Introduction
Tangshan Longquan Chemical Auxiliary Co., Ltd. is a Chinese specialty chemical company focused on plastics and rubber additives, with an emphasis on light stabilizers, UV absorbers, and antioxidant-related products used to improve polymer durability and processing performance. The company states that it was established in 1988, later relocating to its current base in Nanpu Economic Development Zone, Tangshan, Hebei Province, where it operates a modernized production site built in 2015 and placed into operation in 2016.
Within the plastics industry, Tangshan Longquan belongs to the upstream specialty-additives segment that supports the performance of polymers exposed to heat, oxygen, and ultraviolet radiation. Its product profile, exhibition presence, and reported cooperation with related marketing partners indicate a business positioned around polymer stabilization technologies, especially for applications where long-term weatherability and color retention are important.
History and Development
Tangshan Longquan’s corporate history, as presented on its official website, begins in 1988, when the company was established under an earlier identity as Langfang Longquan Flux Co., Ltd.. The company later developed a dedicated industrial base in Tangshan’s Nanpu economic zone, a location that is part of one of China’s major chemical-industry clusters.
A major development milestone came in 2015–2016, when the Tangshan facility was constructed and then brought into production, supported by 20 million yuan in registered capital. The company reports a site area of 100 mu, with the first phase covering 80 mu, suggesting a staged development strategy rather than a single one-time expansion.
Another milestone is the company’s recognition as a high-tech enterprise in Hebei Province’s 2019 third batch of proposed high-tech enterprises, indicating that its product development and technical capabilities were viewed as meeting the province’s qualification standards.
Business Operations and Segments
Publicly available information suggests that Tangshan Longquan operates primarily as a specialty chemical manufacturer serving the plastics and rubber sectors. Its business appears concentrated in chemical auxiliaries rather than commodity resins or large-scale polymer production.
Key operational characteristics reported by the company include:
- Factory location: Nanpu Economic Development Zone, Tangshan City, Hebei Province.
- Registered capital: 20 million yuan.
- Workforce: about 120 employees, including 18 technicians with senior-engineer titles.
- Industrial environment: located in a major chemical-industry park, which is relevant for feedstock access, logistics, and regulatory oversight.
Industry market listings also identify the company as active in plastics and rubber and associate it with five product categories and three application areas on CHINAPLAS Online’s exhibitor directory.
Products and Technologies
Tangshan Longquan is best documented as a producer of polymer additives used in stabilization and aging resistance. Available materials point to a product portfolio that includes:
- UV absorbers
- Light stabilizers
- Antioxidant-related additives
- Related specialty intermediates or auxiliaries for performance plastics and rubber compounds
Industry exhibition materials associated with the company and its marketing partner show the broader OMNISTAB-related line including UV absorbers, light stabilizers, phosphite antioxidants, NIR absorber masterbatch, polyurethane anti-yellowing additives, and photovoltaic material weather modifiers. While this exhibition content is not a complete corporate product catalog, it does indicate the technological neighborhood in which the company operates: additives designed to improve resistance to photo-oxidation, discoloration, and weathering.
In plastics processing, these additive classes are typically used in applications where end users require:
- extended outdoor service life
- reduced embrittlement and surface degradation
- preservation of mechanical properties under heat and UV exposure
- improved appearance retention in molded or extruded products
A market report on HALS intermediates identifies Tangshan Longquan as a participant in the hindered amine light stabilizer supply chain, reinforcing its relevance to the stabilization segment rather than broad chemical manufacturing.
Applications and End Markets
CHINAPLAS Online lists the company as serving three applications, though the excerpt available in the search results does not name them specifically. Based on the product categories identified in other sources, the company’s additives are most plausibly used in:
- Plastics compounding and processing
- Rubber formulations
- Weather-resistant materials, including outdoor and engineering plastic applications
Exhibition references to photovoltaic material weather modifiers and polyurethane anti-yellowing additives suggest exposure to end markets beyond conventional packaging, including construction materials, automotive-adjacent polymers, agricultural films, electrical and electronic materials, and solar-related polymer components.
Global Presence and Market Position
Tangshan Longquan appears to be a specialty supplier with international-facing industry exposure, rather than a broad multinational producer. Its presence on CHINAPLAS Online and participation in CHINAPLAS-related exhibition activity indicate that it operates within the trade-show and export-oriented ecosystem common to Chinese specialty chemical firms.
A strategic cooperation noted by Deltachem began in 2015, and later exhibition coverage shows the two companies working together at CHINAPLAS 2023 to present OMNISTAB-branded additive products. This suggests Tangshan Longquan has participated in collaborative commercial channels and product marketing arrangements aimed at the plastics-additives market.
Market research directories and reports list the company among manufacturers active in HALS and related stabilizer markets, indicating recognition in specialist industry databases, though not enough public information is available to quantify market share.
Sustainability and Environmental Initiatives
No detailed sustainability report was identified in the available search results. However, the company’s product focus has clear environmental relevance because plastic stabilizers can extend service life, which may reduce material replacement frequency in durable applications.
At the same time, specialty chemical manufacturing carries standard industry concerns related to:
- process safety
- emissions control
- waste handling
- occupational health and chemical management
Because the available results do not include audited environmental disclosures, any stronger claims about environmental performance would be unsupported. The most defensible statement is that the company operates in a segment where regulatory compliance and production safety are central to competitiveness.
Financial Performance and Economic Impact
No public financial statements, revenue figures, or profit data were identified in the available sources. The company’s scale can only be described indirectly: it reports 120 employees and a dedicated manufacturing site, indicating a small-to-mid-sized specialty chemical operation by industrial standards.
Its economic role is tied to the wider plastics value chain through the supply of additive chemicals that help downstream processors improve product durability and performance. By serving producers of plastics and rubber auxiliaries, the company contributes to the functionality of downstream products used in consumer, industrial, and infrastructure markets.
Leadership and Corporate Governance
The available sources identify Yongsheng Ji as a contact person for the company, but they do not provide a full leadership roster or governance structure. No board composition, ownership breakdown, or executive biographies were found in the supplied material.
The company’s public footprint suggests a privately operated industrial enterprise with a technical workforce that includes 18 senior engineers, which is consistent with a product-driven specialty chemical business.
Innovations and Future Outlook
Tangshan Longquan’s future prospects are likely linked to demand for high-performance polymer stabilization, especially in applications requiring longer outdoor durability, better thermal stability, and resistance to yellowing or UV degradation. These themes align with broader industry trends toward longer-life plastics in construction, renewable energy, transportation, and consumer goods.
Its reported recognition as a high-tech enterprise and its positioning in HALS and UV-related additives suggest that ongoing competitiveness will depend on:
- formulation performance
- process consistency
- compliance with chemical safety and environmental rules
- ability to support downstream customers with tailored additive packages
The company’s exhibition activity and association with additive brands indicate continued engagement with the plastics trade environment, where customer access and technical service remain important commercial differentiators.
