Elastomers

ESBR (emulsion polymerization styrene-butadiene rubber)

Characteristics

Non-Oil Extended Styrene Butadiene Rubber / ESBR

JSR 1500

The most typical grade of staining type non-oil extended ESBR. It excels in physical properties such as tensile strength, tear resistance, aging resistance, and abrasion resistance. Furthermore, since rosin acid soap is used as the emulsifier, it abounds in tackiness, and excels in processability.

JSR 1502

A mixed soap of rosin acid and fatty acid is used as the emulsifier, and it is the most typical grade of non-staining, non-oil extended ESBR.

JSR 1507

This is a low Mooney Viscosity, non-staining, non-oil extended ESBR.

JSR 0202

Non-staining, non-oil extended ESBR having high Bound Styrene.

JSR 1503

Non-staining, non-oil extended ESBR having good water resistance.

Oil-Extended Styrene Butadiene Rubber / ESBR

JSR 1723

The most typical grade of staining type oil-extended ESBR and a successor grade of 1712.
(aromatic extender oil).It has good dynamic properties, abrasion resistance, economical and excellent processability.

JSR 0122

This is a successor grade of 0120, and high styrene type of 1723.

JSR 1778

A typical non-staining type oil-extended ESBR.

JSR 1778N

A typical non-staining type oil-extended ESBR.

  • *The extender oil used for JSR 1712, 0120 has been changed to a harmful component reduction type for environmental measures.
