2. Physical Properties of Rubber Cover

Grade	Tensile Strength/Mpa ≥	Breaking Elongation/% ≥	Abrasion Loss/mm3 ≤
H	20	400	200
D	18	400	120
L	15	350	200
Note:Grade H-used for highly-sharp working conditions.Grade D-used for highly-abrasive working conditions.Grade L-used for general working conditions.

After-aging properties of rubber cover(70℃×7d):

Change rate of tensile strength & breaking elongation: -25%~+25%.

3. Adhesion

a. Adhesion between rubber cover and belt core: ≥12N/mm.

b. Adhesion of steel core (N/mm)
