Conveyor Belt - Shuangma Rubber

Shuangma Rubber is manufacturer and supplier of rubber conveyor belt in China for many years, "Shuangma" industrial conveyor belts constitute Polyester conveyor belt, (EP), Nylon Conveyor Belt (NN) , Cotton conveyor belt, (CC), Chevron conveyor belt, (C5). The above constructions, with a wide range of protective rubber covers, are manufactured in widths up to 2000 mm(78.7 inches) in a most modern automated plant, using the finest raw material inputs.

A.
¤ Lower longitudinal elongation
¤ Higher tensile strength
¤ Good flexibility and troughability
¤ Good resistance to mildew, moisture and rotting
¤ Good resistance to edge wear
¤ Excellent impact resistance
¤ Unaffected by alkalies and weak acids
¤ Suitable for conveying material over long distances

B.
¤ Besides having the advantages as listed for NN carcass belts, EP belts have the additional advantage of lower longitudinal elongation.

C.
¤ Suitable for most applications
¤ Good bonding for rubber
¤ Good fastener holding properties

D.
¤ Good troughability
¤ Resistance to longitudinal tearing and damage due to edge turn up
¤ Improved resistance to impact damage
¤ Lighter in weight
¤ Better mechanical fastener holding properties
