产品说明:

Selar® PA 3426 is an amorphous nylon (polyamide) resin which exhibits superior transparency, good barrier properties to gases, water, solvents and essential oils and high temperature structural properties which make it suitable for consideration in a number of packaging applications. It can be processed on conventional extrusion and injection equipment designed to process nylon ｏｒ polyolefin resins. It is available in the form of small, free flowing pellets in 25 kg (55 lb.) foil-lined bags ｏｒ 750 kg. (1653 lb.) foil lined boxes.
