Proto Labs Inc. introduced medical-grade liquid silicone rubber (LSR) material to its quick-turn injection molding capabilities. The rapid manufacturing company now offers Dow Corning QP1-250 moldable silicone in addition to its standard and optical-grade LSR materials. Medical-grade LSR is a low-viscosity thermoset material suited for medical applications. Proto Labs can manufacture 25 to 5,000+ parts in 1 to 15 days.
Parts created in LSR are strong and elastic with excellent thermal, chemical and electrical resistance. They maintain their physical properties at extreme temperatures and withstand sterilization. LSR is biocompatible so it is frequently used in products that require skin contact. As a result, moldable silicone lends itself to surgical and dental applications, consumer health care products and other components that have human contact.
