K-Resin® KR99HG

Polymer,Thermoplastic,Styrene-Butadiene,Styrene-Butadiene Copolymer, SBC

Chevron Phillips Chemical Company LP

产品说明:

Styrene-Butadiene Copolymer

Customer Benefits: This SBC is easily processed by injection molding. Molded parts provide excellent part detail on fast production cycles. Molded parts have excellent clarity, good toughness, excellent stiffness, high surface gloss, and can be blended with Polystyrene.

Applications: Garment Hangers

Processing Recommendations:
Melt Temperature: 232°C, maximum. Screw: plasticizing type injection molder more desirable than plunger type molder. Generally no need to dry resin.
