GON-B5330 is a low-density ethylene-butene POE copolymer (77.6% ethylene, 22.4% butene). Optimized for high-grade TPO modification, it offers great flowability, superior impact resistance, high light transmittance, ultra-low cold resistance and ultra-high elongation. Provided as cylindrical pellets for injection & extrusion, widely used in PV, auto, home appliance and footwear fields.
Low-density ethylene-butene copolymer structure with excellent melt fluidity for smooth extrusion & injection molding
Exceptional impact resistance and ultra-low temperature toughness with glass transition temperature ≤ -49°C
Ultra-high elongation at break over 950%, flexible Shore A 70 hardness for great elasticity
Outstanding light transmittance: ≥86% for UV band and ≥91% for visible & near-infrared light
Extra-high volume resistivity ≥10¹⁵ Ω·cm with reliable insulation performance
Compatible with TPO, PP and polyolefin materials as high-efficiency impact modifier
Stable physical properties, uniform cylindrical pellet form, 25kg sealed bag packaging for easy storage
