Silicone Mold Release Agent for Rubber

CAS: 9006-65-9

Silicone-based mold release agents for rubber molding are used to prevent adhesion between cured rubber compounds and metal mold surfaces, enabling clean part ejection and extending mold life. They are available as solvent-based sprays, water-based emulsions, and semi-permanent coatings to suit different molding processes including compression, transfer, and injection molding. Silicone mold releases are compatible with a wide range of rubber types and cure systems including sulfur-cured and peroxide-cured compounds.

Silicone Rubber Cure Inhibitor (LSR/RTV-2)

Silicone cure inhibitors are used in platinum-catalyzed addition-cure silicone systems to extend pot life and working time at room temperature while maintaining fast cure at elevated temperatures. They function by temporarily complexing or deactivating the platinum catalyst below a threshold temperature. Common inhibitor types include ethynylcyclohexanol, diallyl maleate, and 2-methyl-3-butyn-2-ol, which are used at concentrations of 0.01–0.5% to tune working time from minutes to hours.

Stearic Acid (Rubber Grade)

CAS: 57-11-4

Stearic Acid rubber grade is a critical vulcanization activator used in combination with zinc oxide to form the zinc stearate complex that activates accelerated sulfur vulcanization. It also acts as an internal lubricant to improve processing, reduce compound viscosity, and aid dispersal of fillers and other compounding ingredients. Rubber-grade stearic acid is available in flake and bead forms.

TDAE Aromatic Process Oil (Tire Grade)

CAS: 64742-94-9

Treated Distillate Aromatic Extract (TDAE) is the EU-compliant replacement for traditional DAE aromatic process oil in tire tread compounds. TDAE retains the excellent solvation power of aromatic oils for SBR and BR polymers, ensuring good filler dispersion and compound processing, while its reduced polycyclic aromatic hydrocarbon (PAH) content complies with EU Directive 2005/69/EC and REACH regulations. TDAE is the standard extender oil for emulsion SBR and is widely used in tire and industrial rubber compounding.

Zinc Oxide (Rubber Grade)

CAS: 1314-13-2

Zinc Oxide rubber grade is an essential vulcanization activator that, in combination with stearic acid, activates accelerated sulfur vulcanization by forming zinc complexes with accelerator decomposition products. It also improves thermal conductivity, heat dissipation, and abrasion resistance in rubber compounds. Rubber-grade ZnO is available in indirect-process and active nano grades to suit different compound requirements.
