Chem-Trend introduces new biocompatible release agent for medical silicon products

Specifically for the manufacture of silicone rubber products for medical applications, US-based Chem-Trend has developed a new, biocompatible release agent, Mono-Coat 1989W.

Suitable for the molding of medical parts such as medical tubes, protective caps and closures, the semi-permanent, water based release agent is certified in accordance with the USP Class VI panel of tests.

"Because of its high level of purity, its good biocompatibility, and its high resistance to mechanical stress silicone rubber is widely used for medical applications," said George Barton, Chem-Trend Senior Business Development Director for the rubber industry. "In addition, the new release agent helps reduce scrap and delivers a higher efficiency in the production of silicone rubber medical products."

Mono-Coat 1989W ensures easy release of the finished products from the mold and facilitates the manufacture of clean parts. The new release agent features high temperature and abrasion resistance, and offers multiple releases with little to no transfer to the molded part, said Chem-Trend.

In biological compatibility tests conducted by the independent medical research organization NAMSA, Mono-Coat 1989W was found to meet the requirements of the USP Class VI panel of tests.

The certification was also granted to its Mono-Coat 1973W, which is used in the manufacture of non-silicone medical rubber components, added the company.
