Ns302-Red Engineering Plastic, Composite Stone (Durostone)

Item :  NS302-Dark Red Durostone

Product Description

Durostone NS302-DR the is 5 color in this series, there are black ,blue, grey ,dark red and green.
If customer have different item or products , then he can buy different durostone material for distinguish the item during the production .This item can withstand the temperature more than 300 degree (10~20seconds). And keep its mechanical strength, smoothness and original color when continuously used during the temperature of 280°c .Composite materials ( durostone) it is a very good material for Insulation test fixture, wave soldering, reflow soldering, SMT , oven tray, had tin furnace jig
Product Features
