This material is a nylon blend.
It consists of a mix of standard unreinforced PA 6 (50% by weight) and a customized PA 6/6 that has been reinforced with standard short glass fiber using a commercially available coupling technology, at a glass loading of 30% by weight.
By weight, the resulting blend is thus 50% PA 6, 34.5% PA 6/6, 15% glass fiber, and 0.5% coupling agent.

Why Use Plastic?
corrosion resistance!
molded-in color!
reduced weight!
molded-in features!
global availability!
design freedom!
net shape manufacturing !
energy efficient!
accurate and repeatable !
environmentally benign!
part consolidation!
lower part costs!
end-use performance!
99% of the time - we make something out of plastic because it is a cost effective manufacturing method
WORKING TOGETHER

ease of use and re-use !
Property Data WORKING TOGETHER
“The designer who has access to standard data sheet values only must use them cautiously as a source of design information. Many of the tests reported on the sheets come under the jurisdiction of the American Society for Testing and Materials (ASTM), and the properties are intended to characterize a material, not necessarily to provide design information.”
