Application Of Solution Polymerized Styrene Butadiene Rubber In Shoe Making Formula

Solution polymerized styrene butadiene rubber (SSBR) is polymerized from butadiene and styrene in the presence of butyl lithium catalyst in hydrocarbon solvent.

Mainly are the following: 1205: butadiene 75%, styrene 25%. low temperature resistance, wear resistance, bending resistance, compression deformation, mixing compound has high hardness;

1430: increase hardness, flexibility and wear resistance;

Another SSBR 303: is used in pparent rubber.

1205 mainly produces 75 or less common material or trademark material, 1430 mainly produces 75 degree hardness above the standard or special material.

For example, 1205 formula:

5L 20

BR 50

120530

White carbon black 45

Dispersant 1.5

ZNO 5

STA 1

NS 1.3

DM 0.4

19871.5

This formula has a hardness of about 65 degrees and can be used as a general sports shoes.

This formula is one of the series of formulations for a ADI company. I feel that the dosage of accelerator is a little larger, and the pH and pH may not be adequately treated.

For example, a 1430 recipe is made as a standard material, because the material usually touches the ground and needs to be skid resistant.

The hardness is 80 degrees and the wear is less than 0.5.

This is a standard recipe for NIKE. It's really good.
