Mold Release Agent for Rubber Molding

Mold Release Agent for Rubber Molding

Reliable Rubber Mold Release, Improved Rubber Flow Out, Cost-Effective – a potent combination.

Miller-Stephenson has pioneered mold release agent coatings for rubber molding for more than 40 years. The ReleaSys product is a designed to perform in today’s higher temperature and shorter cycle production facilities.  Developed in conjunction with our rubber manufacturing customers, ReleaSys Rubber mold release agents provide mold surface with a high lubricity, thin film. The release agent film seals micro porosity, enhances rubber flow out and facilities long lasting release performance.  Durability and abrasion resistance is dramatically increased as well, without any mold build-up or oily residue. The unique chemistry used in mold release agent for rubber mold are used across the globe to make golf balls, airplane door seals, gaskets, floor mats, nitrile seals, etc.  Miller-Stephenson ReleaSys Mold Release Systems deliver the highest performance, cost effectiveness, and release ease available.

Mold Release Agents for Rubber Molding Benefits:

  • Superior part release: ReleaSys mold release agents are formulated to maximize releases per applications and improve surface quality.  The result: Reduced down time and fewer defects.
  • Higher efficiency: ReleaSys was designed to maximize releases per applications and minimize mold fouling, which ultimately leads to less time spend applying mold release agents and less time cleaning up the residue.
  • Non Reactive Coatings: Miller-Stephenson’s rubber mold release coatings contain advanced polymers which rapidly form durable, inert films on the mold surface. The low surface energy release film is resistant all vulcanization practices including peroxide, sulfur, etc.
  • Water based, no VOC emissions, cleaner safer working environments: ReleaSys rubber mold release agents are water based, zero VOC and intrinsically safer
  • Minimal Transfer: ReleaSys rubber mold release agents are designed to crosslink and form a tough, durable film on the mold surface, eliminating transfer.
  • Higher quality parts: ReleaSys is designed  to enhance rubber flow out, smoothness and ease of release. The result are improved surface quality, fewer rejected parts and better output.
