PA6 – Polyamide 6 PA6
AKROMID® B3 HU grey (7897)
AKROMID® B3 HU grey (7897) is an at UL listed unreinforced and heat stabilised polyamide 6 colored in light grey (RAL 7035)
Housings, cable glands and fixtures in the automotive and electric industry.
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.
