ultra-high elongation tear-resistant high-toughness robot skin silicone is a newly upgraded high-strength dynamic platinum-cured RTV-2 liquid bionic silicone launched by Shenzhen Hong Ye Jie Technology, targeting the industry pain points of insufficient toughness, low ultimate elongation, stress whitening and easy cracking of traditional robot skin under large-angle extreme deformation. Conventional bionic silicone adopts short molecular chain structure with limited tensile capacity and poor tear resistance. It can only adapt to small-amplitude joint movement, and is prone to local thinning, whitening, micro-cracks and edge chipping under large-angle flexion, full palm opening and exaggerated facial stretching. Long-term high-tension dynamic movement will cause continuous expansion of skin damage, frequent skin replacement and high operation cost, which cannot meet the mass production and stable operation requirements of high-end large-dynamic humanoid robots. This product adopts long molecular chain polymerization toughening technology to optimize internal cross-linking structure, greatly improving ultimate tensile elongation, tear strength and overall structural toughness, fundamentally solving the cracking and tearing failure problems of bionic skin under extreme dynamic working conditions.
It adopts stable 1:1 weight ratio mixing, room temperature curing and heating accelerated curing, compatible with pouring and brushing processes, suitable for integrated molding of robot full-body high-tension dynamic skin, large-angle joint cladding, palm opening tension area and exaggerated micro-expression stretching layer. The hardness ranges from 6A to 28A to meet differentiated extreme dynamic simulation needs. 6-16A ultra-soft high-toughness grade is suitable for facial, eyelid and neck extreme stretching areas, with uniform stretching and no stress whitening or micro-cracks during exaggerated expressions. 18-28A high-strength anti-tear grade adapts to high-tension parts such as wrists, elbows, knees and ankles, resisting extreme stretching, large-angle bending and high-frequency deformation without fracture or edge damage, perfectly adapting to all-weather high-load dynamic operation.
The core advantage lies in ultra-high elongation + extreme tear resistance + zero cracking under large deformation. Different from ordinary silicone that is fragile and easy to crack under high tension, this material features excellent uniform tensile performance and structural toughness. After tens of thousands of extreme stretching and large-angle bending fatigue tests, the skin extends evenly without local thinning, whitening or residual micro-cracks. The edge structure remains complete without chipping, tearing or damage after extreme joint movement and limb swinging, maintaining long-term skin integrity and dynamic simulation stability, thoroughly solving the frequent damage and replacement problems of large-dynamic robot skin.
With ultra-low curing shrinkage rate ≤0.08%, the material accurately restores human skin micro-pores, shallow textures and natural tensile lines, presenting realistic static simulation effect and natural dynamic stretching texture consistent with human movement logic. The upgraded high-toughness color fastness formula ensures stable color performance without whitening, mottling or fading during repeated extreme deformation. It retains excellent dynamic fatigue resistance and high resilience, with rapid reset and zero residual deformation after extreme movement, balancing ultra-high structural toughness and delicate bionic simulation fidelity.
The material features excellent high-stress dispersion performance, effectively avoiding local stress concentration and skin cracking in high-tension areas. The dense and tough surface structure resists dynamic friction and high-load deformation loss, without peeling, delamination or cracking during long-term extreme dynamic operation, greatly extending the service life of high-dynamic bionic skin. Adopting high-purity medical-grade platinum eco-friendly curing system, the silicone is non-toxic, odorless and skin-friendly with excellent biocompatibility, safe for long-term high-intensity human-computer interaction and close dynamic display. It has moderate fluidity and smooth defoaming performance, producing flawless finished products with uniform toughness and tensile performance, suitable for high-end dynamic robot sample testing, extreme simulation customization and large-scale mass production with stable batch consistency.
Shenzhen Hong Ye Jie Technology has built a full-scene differentiated bionic silicone matrix covering ultra-soft micro-expression, low-bleed dry-touch, weather-resistant anti-aging, high wear-resistant scratch-proof, high resilience anti-fatigue, matte anti-fingerprint and this new high-elongation tear-resistant high-toughness type. We support customized hardness, skin tone and toughness reinforcement, free sample testing and full-process technical guidance, helping global high-end dynamic humanoid robot and extreme simulation industries solve large-deformation cracking problems and improve extreme working condition stability.

Operating Instructions
Fully stir Part A and Part B before use to evenly disperse high-toughness tensile fillers and ensure uniform dynamic performance. Mix strictly at 1:1 weight ratio and stir thoroughly by scraping bottom and walls to avoid local toughness weakness. Vacuum defoaming is required to eliminate tiny bubbles and prevent stress weak points. Room temperature pot life is 40-50 minutes, full curing for 5-9 hours. Heating curing at 60-80℃ speeds up mass production without damaging core high-elongation and tear-resistant performance.
Notes
Platinum silicone will be poisoned and fail to cure when contacting sulfur, tin, lead and phosphorus contaminants, resulting in toughness attenuation. All tools and molds must be clean and dry without oil pollution. Avoid violent over-limit stretching and sharp cutting. Ensure uniform skin thickness for high-tension joints to prevent stress concentration. Complete extreme deformation safety test before commercial application.
Packing & Storage
Part A and Part B packed separately in sealed drums: 5kg, 20kg, 200kg. Store in cool, dry and ventilated sealed environment, away from high temperature pollution and sharp hard objects. Shelf life: 12 months, transported as non-dangerous goods.
