high elongation and high tear‑resistant robot skin silicone is newly developed for high‑strength dynamic working conditions of humanoid robots, especially for large‑angle joint flexion and extension, arm torsion, palm opening and closing deformation, and exaggerated facial expression stretching. It solves the common industrial defects of traditional bionic silicone such as easy cracking under large deformation, low tear strength, whitening after stretching, elastic attenuation and fatigue fracture after long‑term high‑frequency movement. Widely used for dynamic skin of robot shoulders, elbows, wrists, waists and knees; flexible facial expression skin and high‑toughness finger‑palm skin; large‑deformation film special‑effect prosthetics, high‑flexibility wearable silicone masks, rehabilitation prosthetic liners and dynamic medical simulation models. It is the preferred high‑toughness bionic material for humanoid robot large‑range dynamic motion scenarios.

Full Product Description
HYJ‑RS‑038 high elongation high tear‑resistant high resilience robot skin silicone is a newly upgraded high‑toughness platinum‑cured RTV‑2
liquid silicone independently developed by Shenzhen Hong Ye Jie Technology. Different from ordinary soft but low‑toughness bionic silicone on the market, this product adopts a new molecular chain toughening modification technology, which greatly improves elongation at break, tear strength and dynamic resilience toughness. While maintaining ultra‑realistic human skin soft touch, it achieves no tearing under super large deformation, no fracture during extreme stretching and no fatigue damage after high‑frequency bending, perfectly adapting to the new generation of humanoid robot full‑body high‑dynamic operation requirements and solving the long‑standing industrial pain point of “soft but fragile” for traditional bionic skin materials.
This product adopts 1:1 weight ratio mixing, room temperature curing and heating accelerated curing, compatible with pouring and brushing molding processes. It can form complex curved surfaces, special‑shaped joints, thin‑wall soft skin and thick‑wall stress structures in one piece. The hardness ranges from 0 to 25 Shore A. The ultra‑soft 0‑8A grade is suitable for robot face, eyelid, lip and fingertip ultra‑thin flexible skin, supporting exaggerated expression stretching and large deformation rebound without cracking. The 10‑25A high‑toughness elastic grade is specially optimized for robot shoulders, elbows, wrists, waists and knees, with excellent tear resistance, torsion resistance and folding resistance, stable and durable under long‑term high‑intensity dynamic operation.
Featuring ultra‑high elongation, superior tear resistance and zero‑lag high resilience, the silicone passes tens of thousands of extreme stretching, tearing and cyclic fatigue tests. It will not become thin, break, whiten or produce hidden cracks under large‑angle deformation and extreme stretching, completely avoiding skin tearing, local damage and edge cracking during robot dynamic movement. The high‑resilience molecular structure enables instant reset after deformation without residual creases, relaxation deformation or rebound lag, ensuring smooth and highly simulated robot dynamic motion effect without skin accumulation or stuttering.
With ultra‑low shrinkage rate ≤0.08%, the material accurately reproduces human skin pores, subtle texture and fine lines with high dimensional stability and ultra‑realistic appearance. The upgraded anti‑yellowing and anti‑aging formula maintains stable elasticity and texture after long‑term high‑frequency dynamic operation, without elastic attenuation, surface hardening, yellowing or oil precipitation, greatly extending the service life of robot bionic skin and reducing later maintenance costs.
Adopting high‑purity platinum eco‑friendly curing system, the silicone is non‑toxic, odorless and skin‑friendly with excellent biocompatibility, safe for indirect human contact. Custom skin tone, translucent and special colors are available with uniform color adhesion and no color cracking under deformation. With moderate fluidity and excellent defoaming performance, it achieves high finished product yield, suitable for laboratory R&D sampling, high‑end customization and large‑scale automated mass production.

Operating Instructions
Stir Part A and Part B evenly before use to disperse settled fillers. Mix at 1:1 weight ratio and stir thoroughly for 2‑3 minutes with scraping bottom and walls. Vacuum defoaming is strongly recommended to eliminate tiny bubbles and ensure uniform toughness. Room temperature working time is 35‑45 minutes, full curing for 4‑9 hours. Heating at 60‑80℃ can shorten curing cycle and improve production efficiency without affecting high‑toughness performance.
Notes
Platinum silicone will be poisoned and fail to cure when contacting sulfur, tin, lead and phosphorus substances. All molds and tools must be thoroughly cleaned before use. Avoid extreme violent pulling and long‑term strong UV exposure. Skin contact products need patch test in advance.
Packing & Storage
Packed in 5kg, 20kg, 200kg drums. Store in cool, dry and clean sealed environment. Shelf life: 12 months, transported as non‑dangerous goods.
