Medical & Prosthetics

TrueSil A35 is one of our most widely used materials for prosthetic socket liners, orthotic pads, and wearable medical components — delivering the skin-safe flexibility and mechanical resilience that long-term body contact applications demand. ISO 10993-tested and fully documented for regulatory submissions.

Sealing & Gasketing

The balanced stiffness and chemical resistance of TrueSil A35 make it an ideal material for custom gaskets, O-rings, and sealing profiles with complex cross-sections. Parts maintain dimensional stability across a wide temperature range and resist oils, solvents, and acids without degradation.

Robotics & Automation

From gripper pads and actuator skins to tactile sensor encapsulations, TrueSil A35 provides the ideal balance of compliance and durability for collaborative robotics applications — offering reliable performance across millions of cycles in demanding environments.
