Resin

A barrier resin par excellence, EVOH is celebrated for its exceptional resistance to gas permeation, effectively impeding the infiltration of oxygen, carbon dioxide, and other gases. Its superior processability, combined with outstanding transparency, luster, mechanical strength, flexibility, abrasion resistance, and cold endurance, make it an indispensable choice in high barrier applications. These include food packaging films, containers, automotive fuel tanks, and underfloor heating pipes.

Distinguished by its remarkable thermal stability, pliability, and elasticity, EMA exhibits excellent compatibility with polymers such as PE, PP, PA, and PVDC. Its affinity for bonding with various substrates renders it an ideal component in the production of films that require softness, elasticity, and robust heat-seal characteristics, such as thermal sealing layers in food packaging. It also serves as a cold-weather toughener for a myriad of high polymers and alloys including ABS, PA, PC, PBT, PET, PBT/PC, PC/ABS, PP, and more.

Grafted polypropylene commonly refers to maleic anhydride grafted polypropylene, which introduces highly polar side groups (maleic anhydride) onto the polypropylene chain, serving as a bridge to enhance the adhesion and compatibility between polar and non-polar materials. It is instrumental in PP + glass fiber modifications and when added in filled polypropylene production, significantly improving the affinity and dispersion of fillers.

TPO’s architecture may feature high-ethylene content propylene copolymers with ethylene propylene rubber structures. It is a composite that melds the robustness of plastics with the resilience of rubber. Renowned for its resistance to UV radiation and chemicals, TPO is a versatile material heralded for its durability and flexibility across various applications, including automotive components, water proofing membrane and consumer goods.

EVA, with its vinyl acetate (VA) content ranging from 5% to 40%, surpasses polyethylene in toughness, impact resistance, filler miscibility, and heat salability. Its applications are extensive, from foam shoe materials, functional greenhouse films, packaging films, hot melt adhesives, wires, and cables, to toys. EVA also enjoys a burgeoning presence in the renewable energy sector, finding utility in photovoltaic materials and as an adhesive for solar cells.

Introducing polar side groups into the non-polar backbone of elastomer molecules, maleic anhydride grafted POE acts as an excellent toughening and computerizing agent. It finds applications in compatibilizers and tougheners for PA/PE, PA/PP alloys, PC, ABS, PET, PBT, and their respective alloys.

With a lower melting point and enhanced toughness, this resin offers superior transparency and sealing qualities, ideal for packaging applications requiring low heat-seal temperatures and robust seal strength

With a density spanning 0.910～0.940g/cm3, LDPE is a versatile polymer widely utilized in applications ranging from blow and cast films to extrusion and coating, rotational and injection molding. VLDPE, on the other hand, with a density of 0.885~ 0.915 g/cm3, excels in impact, tear, and puncture resistance. It’s typical applications include hoses, bag-in-box packaging, low-temperature heat-seal packaging, freezer bags, shrink films, medical packaging, cling films, and more.

With a molecular weight exceeding one million, UHMWPE exhibits exceptional properties, combining impact resistance, low-temperature endurance, wear resistance, chemical resistance, intrinsic lubricity, and shock absorption energy. Its applications span various industrial domains, including machinery, transportation, military, medical, food processing, chemical, electronics, and more. For instance, UHMWPE fibers, emerging as the third generation of high-performance fibers after carbon and aramid fibers, are used in high strength rigging and bulletproof vests.
