PVC PVG Core Heat Vulcanized Joint Compound High Performance Flame Retardant

PVC PVG whole core flame retardant belt heat vulcanized joint compound

Operating procedure of the whole core with joints:

1. Put the beam column, water plate and the lower plate of the curing machine in order to set up the working platform. Find a right angle, cut one end of the belt into full edges, and fix the belt with a G-shaped card;
