Higher Stiffness. Higher Performance.
Industrial Sealing & Functional Components
TrueSil A50's higher stiffness and tensile strength make it the go-to choice for demanding industrial sealing applications — gaskets, custom seals, vibration dampers, and functional components where structural integrity under load and resistance to extreme temperatures and chemicals are critical.
Robotics: Structural Actuators & End-of-Arm Tooling
Where robotic components need to maintain shape under load while remaining elastomeric, TrueSil A50 delivers. Ideal for end-of-arm tooling, structural actuator bodies, and gripper frames that require higher resistance to deformation without sacrificing the compliance advantages of silicone.
Medical Devices & Orthotics
TrueSil A50 is well suited for orthotic components, load-bearing medical device parts, and structural elements in soft medical assemblies where a firmer silicone is required to provide support and shape retention alongside biocompatibility and skin safety.
