Specification:
Conventional Conveyor Belt, generally used for power, grain and block material.
1) Structure: top cover rubber, bottom cover rubber, carcass, skim coat;


2)Performance indexes(GB/T7984)
Performance of cover

Performance of cover rubber	Tensile strength	H	MPa	≥24
		D	MPa	≥18
		L	MPa	≥15
	Elongation at break	H	%	≥450
		D	%	≥400
		L	%	≥350
	Abrasion loss	H	mm3	≤120
		D	mm3	≤100
		L	mm3	≤200
Thickness of cover rubber	The thickness of common top and bottom rubber cover is 3.0+1.5mm, 4.5+1.5mm, 6.0+3.0mm, and 8.0+4.0mm, respectively. Since under normal service condition, the major loss of the rubber belt is abrasion,We recommend customers to increase the thickness of cover rubber appropriately at the time of placing order so as to improve the use value of the belt.

 
Note: The elongation of reference force in longitudinal direction over the full thickness of the belt is not greater than 4%.
