Preliminary datasheet

PA6.10 – Polyamide 6.10 PA610 + PP

AKROMID® S4 4 L black (7805)

AKROMID® S4 4 L black (7805) is a unreinforced, hydrolysis stabilised, higher viscous polyamide-blend with a reduced density compared to standard PA610

Typical applications

Technical components of cooling water cycles in the automotive industry.

Processing information

The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.
