WPIC – Shaping-Up, Mar 2026

This report highlights the importance and applications of platinum-cured liquid silicone rubber (LSR) in manufacturing, especially for medical devices.

LSR is prized for its flexibility, durability, resistance to extreme temperatures, and high purity. Platinum catalysts play a crucial role in curing LSR, ensuring efficient production and superior product quality. The material is widely used in medical applications due to its biocompatibility, chemical stability, and safety. Medical-grade LSR products include respirator masks, surgical tool handles, tubing for heart-lung machines, dialysis, respiratory equipment, catheters, drug dispensing hoses, and implantable devices. Companies like WACKER and DuPont are innovating with platinum-catalyzed LSR to enhance product quality and meet regulatory standards. New LSR grades offer improved flow, lower viscosity, and greater processing efficiency, enabling cost-effective manufacturing of complex medical parts.
