Applied Silicone Releases Next-Generation HCR Silicone Elastomer for Extrusion Processes

Santa Paula, Calif.-based Applied Silicone Corp., a supplier of long-term implantable silicones for the medical device and critical healthcare market, has introduced an implant-grade, high-consistency addition-cure silicone rubber (HCRA) that the company claims is “optimized for improved productivity, better dimensional control, and reduced scrap in extrusion processes.”

The extrusion process requires constant monitoring and adjustment to maintain the dimensional tolerances of tubing. Applied Silicone’s next-generation HCRA 4700 series delivers reduced porosity, high plasticity, long table life, and dimensional stability for faster extrusion line speeds and reduced scrap, according to the company.

Supplied as a two part 1:1 elastomer system, the HCRA 4700 series is available in 20-kilogram kits of 35, 50, and 65 Shore A, which can be blended to create custom durometers or physical property profiles.

“We listened carefully to our customers to define and deliver the optimum properties to improve their overall production process,” said Alastair Winn, president of Applied Silicone. “We are very confident that our optimized HCRA 4700 series combines carefully controlled plasticity and rapid cure to create an excellent base to extrude challenging profiles and maximize line speeds.”

Founded in 1987, the company makes high-purity silicone gels, elastomer dispersions, adhesives, liquid silicone rubber, high-consistency silicone rubber, lubricant coatings, primers, fluids, and sheeting. All products are manufactured in California.
