PA6.6 – Polyamide 6.6 PA66 + PP GF40
AKROMID® A3 GF 40 2 L black (7500)
AKROMID® A3 GF 40 2 L black (7500) is a 40% glass fibre reinforced and UV stabilised polyamide-blend with a reduced density compared to standard PA66 GF 40. The compound offers improved excellent surface quality.
Typical applications
Technical components in the automotive and electronic industry, where a weight 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.
