Liquid silicone rubber (LSR) and polyether ether ketone (PEEK) are excellent materials for manufacturing long-term implantable medical devices. They are often the materials of choice for high-precision, complex or micro-molded components such as seals, membranes, orthopedic implants, electromechanical implants and others.

LSR is a high-purity silicone that offers extreme temperature resistance, high stability, low compression set and other advantages. MRPC specializes in molding LSR materials specified for use in FDA Class I, II and III medical devices.

Using state-of-the-art liquid injection molding (LIM) machines, we use LSR materials to produce some of the industry’s most difficult-to-make components. We also over-mold LSR onto metal or other plastics to create unique products such as orthopedic surgical instrument handles.

PEEK is an organic thermoplastic polymer that has been used for the past 10 to 20 years in the manufacture of implantable medical devices. Because of its biocompatibility, versatility and mechanical and chemical resistance properties, PEEK is increasingly used for medical applications. It also has advantages over metal implants, such as costing less than metal and being more biocompatible with diagnostic imaging.

MRPC uses high-precision machinery to mold PEEK components including dental implants, fixation components, cardiac rhythm management devices, neuromodulation devices and more.
