AKROMID® A3 GF 30 1 L black (4436) is a 30% glass fibre reinforced and heat stabilised polyamide-blend with a reduced density compared to standard PA6.6 GF 30
Typical applications
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.
