Rubber Process Aid FAQ

What makes Blachford a leader in rubber process aids?

High-performance, water-based stearate dispersions engineered for dust-free handling, precise solids, and consistent batch quality at scale —backed by decades of industry trust.

What are rubber process aids?

Specialty additives that improve mixing, flow, and dispersion—reducing viscosity, shortening cycles, and delivering more uniform compounds.

How are process aids different from anti-tack coatings?

Process aids optimize internal mixing and flow; anti-tacks prevent sticking during handling. Different roles, different stages.

Can process aids lower my production costs?

Yes—better filler dispersion and lower viscosity cut mixing time and energy, reduce scrap, and improve first-pass yield.

Who uses Blachford process aids?

Tire manufacturers, custom compounders, and industrial rubber processors (hoses, gaskets, belts), including centralized mixing facilities.

Do you offer FDA compliant process aids?

Yes, we offer FDA compliant products. Please get in touch with us today to discuss your specific needs.

Can you tailor to our elastomers and process?

Yes—solids content, particle size, and surfactant package can be tuned to your polymers, mixers, and throughput targets.

What early results should we expect?

Cleaner lines (low foam/residue), fewer clogs, tighter batch-to-batch variability, and measurable reductions in cycle time and chemical use.
