Near white powder or particles, soluble in water.

The mechanism of action of HP-709 is to replace the sulfur crosslinked bonds that are damaged during molding or product use due to their return to their original state with stable and flexible carbon carbon crosslinked bonds, thereby ensuring long-term thermal stability of sulfur vulcanized rubber materials.

Suitable for most sulfur sulfide polymers (such as NR, IR, SBR, BR, and their blends) to improve their resistance to reversion under oversulfiding conditions.

Suitable for higher vulcanization temperatures, thereby improving production efficiency without compromising product performance.

By generating thermally stable carbon carbon cross-linking bonds to compensate for the loss of sulfur cross-linking bonds due to reversion, the cross-linking density is maintained, thereby controlling the heat generation and thermal degradation of the product during its service life.

Used in the formula of high sulfur curtain fabric adhesive, it can reduce heat generation, maintain the adhesion performance of brass plated steel wire, and improve the heat aging resistance

Used in capsules, it can reduce or eliminate sulfur, thereby overcoming the problem of mold contamination and odor.

There are no regulations in FDA food contact applications

The dosage standard for HP-709 needs to be optimized based on the expected degree of regression (determined by the ratio of accelerator/sulfur). The recommended dosage is as follows:

1. Store in a cool, dry, well ventilated place, away from direct sunlight.

2. Storage period: At least two years under normal storage conditions.
