Rubber / Auxiliaries

Stearic Acid

It is a double-pressed animal-derived product used as a component in rubber formulations and latex as a vulcanization activator. It is also employed as a component in the production of waxes, among other applications.

Zinc Stearate

It is an industrial-grade Zinc Stearate, sometimes used as a component in rubber formulations and latex as a vulcanization activator. It is also employed as a release agent to be applied to the surfaces of semi-processed compounds.

Rubber / Sulfur for Rubber

SULFUR / SULFUR 325

Soluble sulfur is used for the vulcanization of unsaturated synthetic and natural elastomers. It can be used alone or in combination with primary and secondary accelerators.

Rubber / DTDM

Di-morpholino disulfide

The DTDM is a sulfur donor used for the vulcanization of synthetic and natural elastomers, replacing sulfur. The advantages it has over sulfur include the elimination of efflorescence produced by sulfur in raw compounds, for example, 2.5 PHR of sulfur per 1.5 PHR of DTDM. Additionally, it improves Green tack and reversion in natural rubber compounds. It does not stain or alter the color. It enhances resistance to aging and compression set.

Rubber / Insoluble Sulfur OT-20

Homopolymeric Sulfur

Sulfur OT-20 is a polymeric sulfur insoluble in elastomers below a temperature of 120°C. Consequently, it prevents migration and delays pre-vulcanization or scorching of compounds during storage, maintaining the green tack of the surface. Above 120°C, it depolymerizes to become soluble sulfur ready for vulcanization, similar to conventional sulfur.
