1

Thermal aging

1、GM9131P-1994： 80±2°C×240h
2. After 24h at room temperature, wear resistance after standard gm-9909-2004

5000 times of wear-resisting can not see the base material, in the detection surface should have thin and even the flocking face, the velvet belt has no crack, the base material has no obvious bending, no damage.

2

High temperature resistance

1、GM9329P-2003： 80±2°C，95±5% humidity ×240h。
2. After 24h at room temperature, wear resistance after standard gm9909p-2004

5000 times of wear-resisting can not see the base material, in the detection surface should have thin and even the flocking face, the velvet belt has no crack, the base material has no obvious bending, no damage.

3

Heat cycle

1, 80 + 2 ° C x 15.5 h at room temperature 15.5 h - 30 + 2 ° C x 7.5 h at room temperature for 0.5 h50 plus or minus 2 ° C and 95 + / - 5% humidity room temperature is 0.5 x 15.5 h h - 30 + 2 ° C x 7.5 h at room temperature for 0.5 h, the above cycle 5 times.
2. After 24h at room temperature, wear resistance after standard gm9909p-2004

5000 times of wear-resisting can not see the base material, in the detection surface should have thin and even the flocking face, the velvet belt has no crack, the base material has no obvious bending, no damage.

4

The friction resistance

PV3363-2006

Load 250G, travel 70mm. Speed 60 plus or minus 5 reciprocating/min. After 250 times, the rubber layer is in good condition, and the base material can not be found. On the test surface, it should have a thin and uniform flocking surface

5

Wear resistance

GM9909-2004

Standard or room temperature environment, load 1kh, cycle wear-resisting 10,000 times invisible base material, should have thin and uniform flocking surface on the detection surface

6

Xenon aging

Gm9909p-2004, SAEJ2527-2004 (500KJ/square) aged 1KG with 5000 friction loads

On the detection surface should have thin and uniform flocking surface, the velvet belt has no crack, no obvious bending of the base material, no damage.
