Preliminary datasheet

PA6 – Polyamide 6 PA6

AKROMID® B3 3 natural (5772)

AKROMID® B3 3 natural (5772) is an unreinforced, nucleated polyamide 6 with light inherent color.

Typical applications

Applications are thin wall parts and housings for the electro- and electronic market as well as for furniture and mechanical engineering

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.
