Composições de poliolefinas usadas para preparação de folhas gravadas em relevo com retenção de grãos aperfeiçoada

摘要

Embossed sheets having improved grain retention can be made from a polyolefin composition containing a propylene polymer material, a partially crosslinked thermoplastic olefin elastomer composition, and optionally, crystalline polyethylene. Large parts such as automobile door and instrument panels can be formed from these sheets.
