Notes:
NN EP canvas conveyer belt used in very low temperature has the characteristic of cold-resisting, can be used under a circumstance of -40°C and can not break.
Application: suitable for conveying materials outdoors in freezing area, cold storage, etc.
Technical index of NN EP canvas conveyer belt used in very low temperature:
1. NN EP canvas conveyer belt used in very low temperature can be divided into three types, according to the properties of cover: laceration resistant type(H),abrasion resistant type(D) and ordinary type(L).
2. According to the different cold resistant, it can be divided working temperature: from -45 to 50 degree into two types of C1 and C2-Working temperature: from -45 to 50 degree.
