Fabric Cord Conveyor Belt

Product Detail

Fabric Cord Conveyor Belt
Fabric cord conveyor belt is also called multi-ply conveyor belt. It is made of many plies of fabric and cover rubber.






Fabric cord conveyor belt family:
1. Polyester conveyor belt ( EP )
2. Nylon conveyor belt ( NN )
3. Cotton conveyor belt ( CC )

Carcass Type	Carcass Material		Strength Range	Key Features & Application
	Warp	Weft	kilonewtons per meter width
PN or EP	Polyester	Nylon	200 to 2500 KN/m	Low elongation
				Very good empact resistance
			100 to 500 KN/m/ply	Good fastener holding
				Excellent general purpose fabric
NN	Nylon	Nylon	200 to 2500 KN/m	Excellent impact resistance
				High elongation
			100 to 500 KN/m/ply	Good fastener holding
				Now mostly replaced by PN(EP)
CC	Cotton	Cotton	Up to 400 KN/m	Used in special applications,such as plasterboard & hot pellet handling systerms
			56 & 70 KN/m/ply

Adhesion Strength and elongation
Adhesion strength is one of the key item of the quality. If the adhesion strength is weak, then the total strength of conveyor belt will become weak. What's more, the plies of fabric will leave from each other when the conveyor belts work. This will end the service life of the conveyor belt.
Here is the tech data of standard adhesion strength of our conveyor belt. If you request higher strength, tell us your application, we will design special conveyor belt for you.

Fabric type EP	Adhesion ( N/mm )			Elongation
	Between plies	Between Rubber and Fabric
		Cover thickness ( 0.8~1.5mm)	Cover thickness =1.5mm	Longitudinal elongation at break at all thickness of belt %=
mean value	=4.5	=3.2	=3.5	2
lowest data	=3.9	=2.4	=2.9	2
