Healthcare & Wearables
The softest material in the TrueSil range — ideal for anatomical models, skin-contact wearables, cushioning pads, and patient-specific devices where ultra-low stiffness and biocompatibility are essential. ISO 10993-tested for safe prolonged skin and mucosal contact.
Audiology & Custom Ear Devices
Shore 20A delivers the natural softness and flexibility required for comfortable, long-wear ear devices — hearing aid tips, custom earmolds, and in-ear monitors that conform precisely to the geometry of each patient's ear canal without pressure or discomfort.
Soft Robotics & Sensor Skins
The high elongation and ultra-low stiffness of TrueSil A20 make it the material of choice for tactile sensor encapsulations, compliant gripper surfaces, and soft robotic skins where maximum compliance and delicate-object handling are required.
