High strength and abrasion resistance
Origin:China
Model No.:SBR 1502 (Non-staining)
Transportation:35kgs/bale 21tons/20FCL
SBR 1502 is a clear non-staining SBR polymer produced by the cold emulsion process.This yields a random structure and the amorphous nature of the polymer gives poor strength in unfilled compounds but high strength and abrasion resistance with reinforcing
Application as follow:
-tires
-shoe soles
-sporting goods,
-floor coverings
-mechanical goods
-heels
-many more general purpose applications where color stability or freedom from staining is important
Handling Precautions:Direct exposure to sunlight and humidity may cause discoloration or quality deterioration.
Keep the produt away from direct sunlight,humidity and impurities,and store in a cool place.
