Aurora, IL, USA

  • INEOS Styrolution’s Styroflex® 4G80 named as the new material in Custom Profile’s medical tubing solutions for medical device designers

Advantages with production, performance, and regulatory compliance make INEOS Styrolution’s Styroflex 4G80, the clear material of choice for Custom Profile’s medical tubing market

Custom Profile, a leading manufacturer of thermoplastic profile extrusions and sub-assemblies, has selected Styroflex 4G80 from INEOS Styrolution, the global leader of styrenics, to supply medical device designers with safe and innovative, next generation medical tubing options.

Styroflex 4G80, a styrene butadiene block copolymer (SBC) has the ability to be processed into a variety of tubing sizes, offering engineers an alternative to existing medical tubing options. It is both a styrene-based thermoplastic elastomer (S-TEP, TPE-S) and a styrene butadiene styrene styrene-block copolymer (SBSS). The material provides cost and performance advantages while meeting ISO 10993, USP Class VI, and food contact regulations. Custom Profile will extrude this material into medical tubing using its existing production equipment and leverage its processing advantages such as lower temperature for energy savings with greater material yields.

Medical device designers, looking for alternatives to existing options in the medical tubing market, are working to find materials that comply with current and future regulatory trends.  Medical tubing extruded by Custom Profile from Styroflex 4G80 is a phthalate-free option that offers many processing advantages. The result is a clean, safe, cost-effective medical tubing that meets a variety of applications’ requirements.

 “Custom Profile is now a key part of the supply chain for safe, clean medical tubing,” said Steve Maxson, Custom Profile, vice president of sales and marketing. “Through our partnerships with INEOS Styrolution for Styroflex 4G80 and Chamfr for sales and distribution, our employee-owned company is supporting the development of next-generation medical devices.”

Alexander Silvestre, global director, healthcare for INEOS Styrolution says, “We are very pleased that Custom Profile selected Styroflex 4G80 as the solution for their next-generation of medical tubing.  Styroflex 4G80 combines transparency, elasticity, and excellent processability. Mr. Silvestre continues, “The material is compatible with common solvent systems, has excellent bond strength for medical tubing to other fluid delivery devices, and is ideal for meeting industries processing and application requirements.”
