US 2021/0347945 A1 · VEHICLE INTERIOR COMPONENT WITH POLYMER COMPOSITION

Abstract

A component for a vehicle interior is disclosed. The component may be formed from a composition comprising polyketone resin in a range of less than about 40 percent by weight, compatible resin, copolymer, compatibilizer and reinforcing material. An effect on a surface of the component is provided by the composition as a result of crystallinity and half-time of crystallization. The composition may provide crystallinity above about 15 percent and half-time crystallization above about 42 seconds. The component may provide crystallinity in a range of between about 17 to 26 percent. The effect provided by crystallinity and crystallization rate of the composition may comprise a substantially consistent visual effect at the surface of the component. The composition may comprise a polyketone composite material. A method of forming the component providing the crystallinity for the visual surface effect from the composition in a tool as a molded part is also disclosed.
