Auto Interior PP & K8303 Pricing
Vehicle interiors consume large volumes of polypropylene for trims, panels and ducts, and the trend toward lighter cabins keeps that demand firm. High-impact grades serve the parts most exposed to handling and temperature swings.
As with other automotive resins, approvals and lot consistency dominate the buying decision. A grade that drifts in flow or impact can disturb tooling and finished-part results across a model line.
Sinopec K8303 targets these demanding interior and semi-structural uses, where toughness at temperature is part of the specification rather than a bonus.
