Clear & Rubber Alternative Solution for Medical

Heath Schmid, director of business development, Colorite said: “Changes in regulations and market conditions are prompting medical device manufacturers to look for solutions via other materials. The Cellene® TPE compound line is ideal for medical device manufacturers and others looking for alternatives to PVC, phthalate-plasticized compounds and various rubber materials,”

“The line expansion will assist in reducing the development cycle and provide manufacturers with greater options to obtain the durometer rating required for their applications.”
