Introduction

Guangzhou Xinjinlong Industry Co., Ltd. (Chinese: 广州市新锦龙塑料助剂有限公司) is a Guangzhou-based Chinese manufacturer and exporter of plasticizers and related PVC additives. The company is associated with products including dioctyl phthalate (DOP), diisononyl phthalate (DINP), dioctyl terephthalate (DOTP), epoxidized soybean oil (ESBO), dioctyl adipate (DOA), and di(2-propylheptyl) phthalate (DPHP).

Its activities place it within the additives segment of the plastics value chain, where plasticizers modify polymer flexibility, processability, durability, and, in some cases, resistance to heat or migration. Xinjinlong serves PVC processors and distributors involved in products such as flexible films, banners, flooring, synthetic leather, cables, hoses, and other flexible polymer articles. Trade records identify the company’s address as No. 39 Dahua Avenue, Huacheng Street, Huadu District, Guangzhou, Guangdong Province, China.

The company’s commercial profile is oriented toward manufacturing and international supply rather than polymer-resin production or plastics machinery. Its presence at international plastics exhibitions, including VietnamPlas, reflects an export-facing strategy and participation in regional PVC and additives markets.

History and Development

Public company profiles identify Guangzhou Xinjinlong Chemical Additives Co., Ltd. as a related or branch organization and describe the broader Xinjinlong business as having been founded in 1996. The available record indicates several stages in the company’s development:

• Establishment and specialization: The organization developed around chemical additives and plasticizer production, with particular emphasis on PVC applications.
• Expansion into bio-based additives: Epoxidized soybean oil became a significant product category, extending the portfolio beyond conventional phthalate plasticizers.

Trade-data providers record hundreds of export shipments and identify Russia, Vietnam, and the Philippines among important destination markets. Other customs records associate the company with shipments of DOP and related plasticizer products to Vietnam, including material used in PVC banners and printed-sheet production.

The company’s participation in international exhibitions also functions as a business-development channel. At VietnamPlas 2025, Xinjinlong exhibited under the plastics sector and presented a portfolio centered on plasticizers for PVC processors and compounders.

Products and Technologies

Plasticizers for PVC

Plasticizers are incorporated into PVC to reduce intermolecular forces within the polymer and increase flexibility, elongation, and ease of processing. Xinjinlong’s listed product range includes:

The listed product range combines phthalate, terephthalate, adipate, and epoxidized vegetable-oil chemistries. This enables formulators to balance flexibility, volatility, low-temperature behavior, permanence, processing characteristics, and regulatory suitability according to the end use.

Epoxidized soybean oil

ESBO is produced by epoxidizing unsaturated soybean-oil molecules. In PVC, it can function both as a secondary plasticizer and as an acid-accepting co-stabilizer. Its epoxy groups can react with hydrogen chloride released during PVC degradation, helping reduce the catalytic effect of hydrochloric acid during processing and service.

A related company profile describes Xinjinlong’s ESBO production capacity as 100,000 tonnes per year. This figure is a company-associated capacity claim rather than an independently audited industry measurement and should therefore be interpreted as an indication of stated production scale.

Process and formulation considerations

Plasticizer performance depends on more than nominal chemical identity. Important variables include:

• Compatibility with the PVC resin
• Plasticizer concentration and formulation balance
• Volatility and migration behavior
• Resistance to extraction by oils, fuels, or water
• Low-temperature flexibility
• Thermal stability during compounding and calendering
• Interaction with stabilizers, pigments, fillers, and other modifiers

Typical downstream processing may involve high-speed mixing, internal mixing, calendering, extrusion, coating, or plastisol preparation. The suitability of any Xinjinlong product depends on the processor’s formulation, equipment, required performance specifications, and applicable chemical regulations.

Applications and End Markets

Xinjinlong’s additives are relevant to a broad range of flexible-PVC and polymer applications:

• Advertising banners and printed PVC sheets
• Flexible films and coated fabrics
• Synthetic leather
• Flooring and wall coverings
• Wire and cable insulation
• Hoses and tubing
• Gaskets and seals
• Tarpaulins and industrial fabrics
• Packaging-related PVC products
• General flexible molded and extruded articles

DOP shipments identified in customs records have been associated with PVC banner and printed-material production in Vietnam. ESBO and other plasticizers can also be used in flexible films, calendared sheets, and compound formulations, although the precise application depends on product grade and customer requirements.

Demand in these markets is influenced by construction activity, infrastructure investment, consumer goods production, electrical and electronic manufacturing, advertising materials, and the substitution of traditional materials with lightweight flexible polymers.

Global Presence and Market Position

Xinjinlong’s market position is that of a specialized additives supplier serving domestic and export customers. Its international footprint is evidenced by customs records, trade databases, and participation in regional plastics exhibitions rather than by publicly reported market-share data.

Reported export destinations include Russia, Vietnam, and the Philippines, while trade records also identify customers or counterparties in other markets. This geographic pattern places the company within the wider Asian chemicals-trading network, where Chinese producers supply plasticizers and additives to PVC processors, compounders, distributors, and converters.

The company competes in a market shaped by:

• Availability and pricing of feedstocks such as phthalic anhydride, alcohols, terephthalic intermediates, adipic-acid derivatives, and vegetable oils
• Regional PVC demand and construction cycles
• Shipping costs and exchange-rate movements
• Customer requirements for consistency, documentation, and regulatory compliance
• Substitution between phthalate, terephthalate, adipate, citrate, and bio-derived plasticizer systems

No independently verified public market-share figure is established for Xinjinlong. Its visible competitive proposition is instead associated with product breadth, export availability, and specialization in PVC additive chemistry.

Research and Development

The company’s associated profile describes an integrated model involving research and development, production, sales, and service, supported by a technical team and production equipment. Within the plasticizer sector, research and technical work generally focuses on:

• Improving compatibility between additives and PVC
• Controlling color, odor, acidity, moisture, and volatile content
• Enhancing permanence and resistance to extraction
• Developing formulations with improved low-temperature flexibility
• Increasing the consistency of epoxidized-oil products
• Supporting customer trials and process optimization
• Adapting products to changing regulatory and application requirements

For a supplier of multiple plasticizer chemistries, technical service is particularly important because converters often need to adjust formulations rather than replace a single ingredient on a one-for-one basis.

Sustainability and Environmental Considerations

Xinjinlong’s portfolio includes ESBO and other epoxy-functional materials derived partly from vegetable-oil feedstocks. Bio-derived content can reduce reliance on fossil-based raw materials for part of a formulation, although the overall environmental profile depends on agricultural production, land use, processing energy, transport, product lifetime, and end-of-life management.

The company’s portfolio also includes conventional phthalate plasticizers. Their acceptance varies by jurisdiction and application because chemical regulations distinguish among individual substances, exposure routes, product categories, and intended uses. Consequently, the presence of a plasticizer in a supplier portfolio does not by itself establish suitability for a particular regulated market.

Environmental and regulatory priorities affecting the sector include:

• Reduction of hazardous or restricted substances in consumer products
• Development of alternative plasticizers
• Improved migration and emissions control
• Traceability of chemical feedstocks
• Recycling and recovery of flexible PVC
• Management of additives during mechanical or chemical recycling
• Lower-carbon production and logistics

The use of ESBO and alternative plasticizers may support formulation diversification, but it does not eliminate the need for product-specific testing, lifecycle assessment, and compliance review.

Financial Performance and Economic Impact

Publicly available trade-data services indicate substantial export activity, including hundreds of recorded shipments and a reported supplier trade value in the tens of millions of U.S. dollars in one database. Such figures are compiled from trade records and should not be treated as audited revenue, profit, or consolidated financial statements.

The company contributes economically through chemical manufacturing, export logistics, technical services, and supply to downstream plastics processors. Its activity also illustrates the role of specialized additive manufacturers in supporting flexible-PVC value chains that extend from chemical intermediates to finished construction, electrical, packaging, and consumer products.

Public information does not establish a complete breakdown of revenue by product, region, or business segment. Accordingly, the company’s economic significance is best assessed through its manufacturing specialization, export activity, and participation in the international additives supply chain.

Quality Management and Certifications

The ChinaPlas exhibitor listing identifies Xinjinlong as a “Shining Niche” company. This designation relates to the exhibition platform and does not, by itself, constitute a formal product certification or independent assessment of quality systems.

For plasticizer suppliers, quality management typically depends on control of:

• Chemical composition and purity
• Acidity and moisture
• Color and appearance
• Density and viscosity
• Volatile content
• Epoxy value for ESBO
• Batch-to-batch consistency
• Packaging integrity and traceability

The applicability of certifications depends on the specific production site, product grade, destination market, and customer contract. Downstream manufacturers generally require technical data sheets, safety data sheets, certificates of analysis, and documentation addressing relevant chemical regulations.

Innovations and Future Outlook

Xinjinlong’s future prospects are closely connected to the evolution of the global PVC-additives market. The principal opportunities include:

• Growth in demand for alternative plasticizers such as DOTP
• Expansion of bio-derived additives such as ESBO
• Development of grades with lower migration or improved permanence
