AKROMID® T5 GF 50 8 black (6205) is a 50% glass fibre reinforced polyphthalamide with very high stiffness and strength and light inherent color. The material fulfills the requirements according to KTW, DVGW W270, ACS, WRAS as well as NSF. It is suitable for applications that are in contact with cold and hot drinking water as well as food.

Typical applications

Mainly components in domestic and industrial applications that are in contact with food or drinking water.

Regulatory

ACSEU10-2011FDAKTW_coldW270WRAS

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.
