New Low Compression-Set Bionic Silicone

In a humanoid robot, the palm and fingertips do the real work of grasping. They are squeezed, pressed and held under load millions of times over the product life. Ordinary bionic silicone feels soft at first, but after months of gripping it takes a permanent set: the pad goes flat, loses its cushion and grip contour, and the hand starts to slip.

Shenzhen Hong Ye Jie Technology Co., Ltd, founded in 2006 and specialized in silicone rubber, liquid silicone rubber and human body silicone, has developed a low compression-set robot skin silicone that directly addresses this long-term grip problem.

This product resists permanent compression deformation. After repeated pressing and long-time holding under load, it rebounds instead of going flat, so the palm and fingertip pads keep their natural contour, soft cushion and secure grip feel through millions of cycles. It is soft but supportive, holding objects steadily without collapsing.

The material keeps a realistic bionic skin touch, with hardness adjustable from 0A to 25A. It supports vacuum pouring for large outer shells and thin brush coating for fingertips and palm details. The platinum-cure system is non-toxic and meets RoHS and REACH standards.

Besides robot skin silicone, Hong Ye Jie supplies silicone rubber, RTV silicone, foam silicone and liquid silicone rubber for one-stop sourcing. Our factory is ISO9001 certified, with every batch tested for compression set and rebound performance.

We welcome humanoid robot makers, collaborative robot integrators and soft gripper producers to contact us for free samples and compression set test reports. We can customize hardness, color and viscosity, and support stable bulk supply.
