Its business model also includes international trade. Supplier-directory information associates Lepuz with overseas markets including the United Kingdom, South Korea, Canada, Malaysia, and Australia, although directory-based geographic percentages should not be treated as audited measures of revenue or market share.
Products and Technologies
Antioxidants
Lepuz markets polymer antioxidants, including antioxidant 1010, a hindered phenolic antioxidant identified by Chemical Abstracts Service number 6683-19-8. Such additives are used to reduce oxidative degradation during polymer processing and long-term service, particularly in polyolefins and other thermoplastics.
Antioxidants are commonly selected according to:
- Processing temperature and residence time
- Polymer type and molecular structure
- Required color stability
- Exposure to heat, oxygen, and mechanical shear
- Interaction with phosphite or other secondary stabilizers
Antioxidant 1010 is generally used in applications involving polypropylene, polyethylene, polyurethane, ABS, and related polymer systems. It is normally incorporated through dry blending, masterbatching, or compounding.
Light stabilizers
The company’s listed product information includes hindered amine light stabilizers, commonly known as HALS, including grades associated with applications such as polypropylene fibers, flat yarn, low-density polyethylene, and linear low-density polyethylene agricultural films.
HALS function primarily by interrupting photo-oxidative degradation cycles. They are particularly relevant to outdoor products, where ultraviolet radiation can cause embrittlement, cracking, fading, and loss of tensile performance. Formulators generally select HALS according to polymer chemistry, film thickness, pigment system, agricultural chemical exposure, and required service life.
Slip and processing additives
Lepuz is associated with erucamide, a fatty-acid amide used as a slip additive in polymer films. Erucamide can migrate gradually to the film surface and reduce the coefficient of friction, improving winding, unwinding, bag manufacture, and handling performance.
In flexible packaging and agricultural-film production, slip additives are typically balanced against:
- Coefficient of friction
- Surface bloom and appearance
- Sealability
- Printing and coating adhesion
- Additive migration
- Time required to reach target surface performance
Optical brighteners
Product listings associated with the company include optical brighteners such as FP-127 for applications including footwear materials. Optical brighteners absorb ultraviolet radiation and re-emit part of the energy in the blue region of the visible spectrum, producing a visually whiter or brighter appearance in selected polymers, coatings, and synthetic materials.
Their performance depends on resin chemistry, processing temperature, pigment loading, dispersion quality, and exposure conditions.
Intermediates and specialty chemicals
Beyond polymer additives, Lepuz supplies chemical intermediates and specialty products for coatings, inks, agriculture, and other industrial sectors. This broader portfolio allows the company to serve customers purchasing multiple classes of chemical auxiliaries, although the technical requirements and regulatory obligations differ substantially among these markets.
Applications and End Markets
Lepuz’s plastic-additive products are relevant to several downstream sectors:
- Flexible packaging: Slip additives, antioxidants, and stabilizers for polyethylene and polypropylene films
- Agricultural films: HALS and antioxidants supporting outdoor weatherability and service life
- Fibers and woven products: Stabilizers and processing aids for polypropylene fibers, flat yarn, and related products
- Automotive and electrical plastics: Stabilization packages for engineering and commodity thermoplastics
- Footwear and synthetic materials: Optical brighteners and additive systems used to control appearance and processing
- Coatings and printing inks: Functional additives and intermediates supporting surface, durability, and formulation properties
- Agriculture: Pesticides, fertilizers, and plant-protection products
The company’s cross-sector portfolio connects it to several major plastics-industry trends, including demand for longer-lasting materials, lightweight packaging, outdoor polymer durability, improved processing efficiency, and more consistent surface properties.
Global Presence and Market Position
Nanjing Lepuz is headquartered in Nanjing, an important commercial and industrial center in eastern China, while its Yangzhou manufacturing operations are situated within the wider Jiangsu chemical and manufacturing region.
The company’s international position is based primarily on chemical-product supply and export activity rather than on ownership of overseas manufacturing plants. Its participation in international supplier directories and plastics exhibitions provides access to compounders, film producers, masterbatch manufacturers, coating formulators, and distributors.
Within the plastics additives market, Lepuz competes through a combination of:
- Product breadth across stabilizers, antioxidants, slip agents, and optical brighteners
- Chinese manufacturing and supply-chain access
- Technical and application support
- Export capabilities
- Ability to serve both plastics and adjacent chemical markets
Its competitive environment includes large multinational additive producers, specialized Chinese manufacturers, regional chemical distributors, and vertically integrated polymer companies. Customer decisions in this market typically depend on consistency, regulatory documentation, batch reliability, price, technical service, and supply continuity rather than on product identity alone.
Research and Development
Lepuz presents technical development and application service as part of its business activities. For plastic additives, research and development generally involves adapting formulations to resin type, processing method, additive concentration, and end-use conditions.
Relevant technical areas include:
- Stabilizer combinations for polyolefins
- Slip and antiblocking performance in films
- Weatherability of outdoor plastics
- Thermal stability during extrusion and injection molding
- Dispersion and compatibility in masterbatch systems
- Color retention and optical performance

In practical manufacturing, additive development is frequently conducted through laboratory compounding, accelerated aging, color measurement, friction testing, and mechanical-property evaluation. The commercial value of such work lies in translating chemical performance into stable production conditions for customers.
Sustainability and Environmental Considerations
Plastic additives can contribute to sustainability by extending product service life, reducing premature failure, lowering scrap rates, and enabling lightweight designs. Antioxidants and light stabilizers, for example, can help preserve mechanical properties and appearance during processing and outdoor use.
At the same time, additive selection must address environmental and regulatory considerations:
- Chemical exposure during manufacture and handling
- Potential migration from packaging and consumer products
- Persistence and degradation behavior
- Worker protection and plant emissions
- Compatibility with recycling processes
- Restrictions affecting food contact, agriculture, and medical applications
For recyclers and compounders, the presence of legacy stabilizers, pigments, fillers, and other additives can affect sorting, reprocessing, odor, color, and final performance. Consequently, additive suppliers increasingly need to provide composition information, safety documentation, regulatory statements, and guidance on use in recycled polymers.
Lepuz describes itself as an ISO-certified enterprise and states that its manufacturing operations follow ISO 9001 quality-management requirements. Quality certification supports process control, although it does not by itself establish environmental performance or product suitability for every regulated application.
Quality Management and Certifications
The company identifies ISO certification and ISO 9001 production and quality-management practices among its operating credentials. In additive manufacturing, an effective quality system normally covers:
- Raw-material qualification
- Batch traceability
- In-process controls
- Purity and assay testing
- Particle-size and appearance checks
- Packaging and labeling
- Retention samples
- Customer complaint and corrective-action procedures
For international sales, customers may also require technical data sheets, safety data sheets, certificates of analysis, statements concerning restricted substances, and application-specific compliance documentation.
Financial Performance and Economic Impact
Lepuz is a privately held chemical enterprise, and publicly available company materials emphasize products, capacity, and business scope rather than audited financial statements. Its reported combined annual production capacity exceeds 50,000 tonnes across two production bases.
The company contributes to the regional chemical economy through:
- Manufacturing and distribution of specialty chemicals
- Employment in production, laboratory, logistics, sales, and technical services
- Demand for chemical raw materials, packaging, testing, and transport
- Export activity from Jiangsu Province
- Supply of inputs used by plastics converters, coating formulators, agricultural businesses, and other manufacturers
Capacity figures indicate operational scale, but they should not be interpreted as actual sales volume, utilization rate, or market share.
Innovations and Future Outlook
Lepuz’s future development is likely to be shaped by the technical and regulatory pressures affecting the broader additives industry. Important areas include:
- Additives compatible with recycled polyethylene and polypropylene
- Stabilizer packages for mechanically recycled materials
