Material Notes:

Styrene-Butadiene CopolymerCustomer 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 HangersProcessing Recommendations:Melt Temperature: 232°C, maximum. Screw: plasticizing type injection molder more desirable than plunger type molder. Generally no need to dry resin.Data provided by Chevron Phillips Chemical Company LP.
