GON-B5350 is a low-density ethylene-butene POE copolymer (77.2% ethylene, 22.8% butene). Designed for high-end TPO modification, it features ultra-high melt flow, outstanding low-temperature toughness, high light transmittance and great flexibility. Supplied as cylindrical pellets for injection and extrusion, widely used in photovoltaic, automotive, home appliance and footwear industries.
Low-density ethylene-butene copolymer with ultra-high melt index, offering superior fluidity for high-speed extrusion and thin-film production
Excellent low-temperature resistance with Tg ≤ -49°C, maintains flexibility and impact strength under cold environments
High elasticity with elongation at break ≥900%, Shore A 72 hardness balances softness and structural support
High light transmittance for UV and visible-near infrared spectrum, ideal for photovoltaic packaging films
Extra-high volume resistivity provides reliable electrical insulation performance
Efficient impact modifier for TPO, PP and other polyolefin materials
Uniform cylindrical pellets, packed in 25kg bags for convenient storage and processing
