PA6 – Polyamide 6 PA6 + PP GF25
AKROMID® B3 GF 25 1 L black (4637)
AKROMID® B3 GF 25 1 L black (4637) is a 25% glass fibre reinforced and heat stabilised polyamide-blend with a reduced density compared to standard PA6 GF 25
Typical applications
Mainly technical components in the automotive and electronic industry, where a weight and cost reduction is required
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.
