PA6 – Polyamide 6 PA6
AKROMID® B3 natural (5230)
AKROMID® B3 natural (5230) is an unreinforced Polyamid 6.
Typical applications
Engineering parts like fasteners, clips, plugs and caps.
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.
