Advantages Of Liquid Silicone Rubber for Medtech Injection Molding

By Calvin Pendorf, Bilal Rafiq, David Pulju, SIMTEC

Manufacturers have recently discovered the advantages of using liquid silicone rubber (LSR) over high consistency rubber (HCR) for injection molding, and for fabricating molded parts. Advantages of using LSR include design flexibility, undercut features, compressibility, and no by-products. LSR is suitable for the custom manufacturing of medical device components ranging from parts for blood analysis machines to surgical instruments. This white paper discusses the different properties and grades of LSR, its injection molding benefits, and the advantages in choosing it for your projects.
