Purpose:
Cold resistant conveyor belt is mainly used for conveying materials in cold areas, such as open air or refrigerated warehouses under - 60 ℃ ~ + 50 ℃.
Structure:
The cold resistant conveyor belt is made of multi-layer impregnated nylon canvas and EP canvas as the skeleton material, covered with cold resistant covering rubber, and made by calendering, molding, curing and other processes.
Features:
This product has the characteristics of cold resistance, high elasticity, impact resistance, wear resistance, etc. it can be used normally under - 60 ℃.
·Executive standard: cold resistant conveyor belt (Hg / t3647-1999)
