Temperature‑Stable Bionic Skin Silicone for Humanoid Robot Dexterous Gripper & Simulation Props

is a wide‑temperature‑resistant, friction‑resistant platinum‑catalyzed addition‑type RTV‑2 Liquid silicone rubber independently developed by Shenzhen Hong Ye Jie Technology Co., Ltd. It is composed of flowable Part A and Part B, mixed at 1:1 by weight. It cures at room temperature, and heating can accelerate curing speed. It supports thin‑wall, thick‑wall and multi‑layer composite pouring molding, suitable for manual prototyping as well as automated mass‑production.

This series covers Shore A hardness from 0‑30A. Ultra‑soft grade (0‑5A) is ideal for soft‑tissue simulation and movie special‑effect prosthetics. Medium‑soft grade (10‑15A) is designed for humanoid robot facial skin and prosthetic inner liners. Medium‑hard grade (20‑30A) applies to frequently‑used medical teaching models and museum display wax figures.

The material features ultra‑low shrinkage ≤0.1%, which can precisely replicate skin pores and fine surface textures. It delivers outstanding wide‑temperature stability, maintaining stable elasticity and mechanical performance within ‑60℃~200℃, no hardening at low temperature and no softening deformation under high‑temperature environment. Optimized friction‑resistant formula resists surface wear after repeated contact and rubbing, reducing surface damage caused by frequent robot grasping and movement. It is compatible with multi‑layer composite molding, can be stacked with different‑hardness silicone layers to realize gradient bionic skin structure. Compared with ordinary simulation silicone, it effectively resists aging, oil bleeding and premature yellowing, extending service life of bionic finished goods.

The silicone is odor‑free and non‑irritating, safe for indirect human‑skin contact. Custom skin‑tone, translucent and transparent colors are available. Good fluidity supports pouring and brushing molding, fitting both R&D sampling and large‑scale automated production.

Shenzhen Hong Ye Jie Technology Co., Ltd also supplies Mold Silicone, Pad Printing Silicone, Electronic Potting Compound, thermal conductive silicone, liquid and solid silicone rubber. We support sample testing, formula adjustment and bulk order delivery. Global buyers are welcome to request TDS and quotation.

Main Features

1. Realistic skin‑like hand‑feel, natural wrinkle recovery after dynamic deformation
2. Wide hardness range 0‑30 Shore A for robot, medical and entertainment scenarios
3. Wide‑temperature resistance ‑60℃~200℃, friction‑resistant, anti‑aging and anti‑yellowing
4. Compatible with multi‑layer composite pouring for gradient bionic skin structure
5. Platinum addition system, skin‑friendly, no harmful volatile substances
6. Low shrinkage for high‑precision texture reproduction; customizable hardness, color and viscosity

Operating Instructions

Stir Part A and Part B separately before mixing to disperse settled fillers. Mix two components at 1:1 weight ratio for 2‑3 minutes, scrape container bottom and side walls. Vacuum degassing is highly recommended to eliminate bubbles. Pot life is 30‑40 minutes at room temperature, full curing takes 4‑8 hours. Heating at 60‑80℃ can shorten curing time.

Notes

Platinum silicone will fail to cure when contacting sulfur, tin, lead or phosphorus substances. Molds and tools previously used for condensation silicone must be thoroughly cleaned. Avoid sharp‑object scratching and long‑term strong sunlight exposure. Small‑area skin test is required for skin‑contact finished products.
