Cover Performance
 

Rubber Cover	Tension Strength Mpa  ≥	Elongation % ≥	Abrasive mm^3, ≤
D	18	450	200
L	14	400	250
Remark: D--- high abrasion;    L---- common working conditions Under 70ºC, 168h, tension strength and elongation changing rate against before testing ≤25%

Safety Performance
 

Combustion Retardant J	K Flame Retardant and Static Conductive
The average flame time of three whole thickness samples in longitudinal direction is not more than 60s, and none reburning phenomenon happesn at each test	Flame retardant requimrent is same as Standard J, Static conductive ≤ 3*10^8

. PVC & PVG whole core conveyor belt adapts PVC or plastic-rubber mixture, which has a good performance on flexibility, light body, easy connection, cheap production cost. It works both for on the ground and underground, but mainly for not so heavy workng tension, not so long transporation distance.

. Flame retardand steel cord conveyor belt adapts higher tension strength, less elongation galvanized steel cord, suitable for the area of fire prevention, explosion-proof, high strict fire alarm. It is used to convey materials at the occasion of long distance, high span large loading and high strength, in flame retardant antistatic enviroments, mainly for coal ming underground conditions. 

According to its flame resistant performance of rubber cover in GB/T10822-2003 standard, here are K2 and K3. Normally K2 is of better performance on flame retardance, working for bad conditions. MT668 standard is only used for flame retardant steel cord conveyor belt underground.  In standard DIN, mainly for K15 and K20. K20 quality has 20Mpa tension and under 60s burning time. K15 is of 15Mpa tension strength and better burning time under 15s.
