Based on many years of experience in Polyamide belt products, GC nylon core belt has great properties due to its classic structure and our usage of good raw material for belt cover and tension member:

1,In total, the belt is divided into 5 layers;

2, For both two sides of the belt (L1 & 5L), also called conveying side and running side/pulley side, they are covered with NBR rubber, and we use XNBR for some belt types ;

3, For traction layer, it consists of one PA foil core layer (L3) and two PA fabric layers (L2 & 4L);

Why choose PA sheet as the core traction member? With 1%-2% standard elongation characteristic, Nylon is a quite flexible material. In the meantime, it can provide great chemical resistance property to the belt, such as oil, ozone exposure, steam, fat, benzine. But do remember that they are not able to be resistant to acids (organic and inorganic), phenols, ketones, and alcohols. And nylon sandwich belt should be placed in a dry and ventilated place, to avoid cracking due to wetting.
