With the rapid commercial upgrading of global humanoid robot technology, robot dynamic flexibility and motion range have been greatly improved. Robots have gradually moved from laboratory small‑range micro motion to commercial full‑body large‑angle joint flexion, limb swing, exaggerated facial expression stretching and high‑frequency palm opening and closing movement. Traditional general bionic silicone can no longer meet the high‑toughness dynamic operation standards of new‑generation commercial robots.
Ordinary bionic silicone generally has the defect of “soft but not tough”. It has soft hand feel but low elongation and poor tear resistance. Under large‑angle torsion, folding and extreme stretching of robot joints, the skin is prone to whitening, thinning and hidden cracks, eventually leading to tearing and damage after long‑term cyclic operation. In addition, ordinary silicone has slow rebound speed and obvious hysteresis, resulting in residual wrinkles and loose skin after robot movement, which makes the bionic effect stiff and unnatural. Long‑term dynamic fatigue will cause rapid elastic attenuation and short service life, bringing high maintenance and replacement costs for robot enterprises.
In high‑end dynamic simulation fields such as film special‑effect large‑movement prosthetics, high‑flexibility wearable masks and medical dynamic training mannequins, traditional silicone also faces the problems of easy cracking under large deformation and insufficient dynamic durability, restricting the quality improvement and service life of high‑end bionic products. The global bionic manufacturing industry is in urgent need of professional high‑toughness bionic skin materials with high elongation, high tear resistance and stable dynamic resilience.
Targeting the dynamic toughness bottleneck of traditional robot skin materials, Shenzhen Hong Ye Jie Technology independently developed and launched HYJ‑RS‑038 high elongation high tear‑resistant high resilience robot skin silicone. Breaking the toughness imbalance limitation of traditional silicone, this new‑generation material adopts molecular chain toughening technology to greatly improve extreme stretching resistance, tear strength and dynamic fatigue resistance while retaining ultra‑realistic human skin soft touch.
The material maintains stable structure without breaking or whitening under ultra‑large deformation, perfectly adapting to exaggerated facial stretching, extreme palm opening and closing and large‑angle joint movement of humanoid robots. The excellent anti‑tear toughness effectively avoids local stress damage and edge cracking during long‑term high‑frequency dynamic operation. The instant high‑resilience performance ensures rapid reset after deformation without residual creases or skin relaxation, making robot dynamic movement smooth, natural and highly anthropomorphic.
After tens of thousands of professional dynamic fatigue tests, the material maintains stable elasticity and toughness without attenuation, hardening or aging, greatly extending the service life of robot bionic skin and reducing commercial operation costs. The ultra‑low shrinkage rate ensures high‑precision restoration of skin texture and delicate details, realizing perfect integration of high dynamic performance and ultra‑realistic bionic appearance.
The eco‑friendly platinum curing system meets international safety standards for indirect human contact. Custom skin tone and special colors are available with strong deformation resistance and color fastness. Widely used in commercial humanoid robot full‑body dynamic skin, large‑deformation film special‑effect prosthetics, high‑flexibility wearable masks and dynamic medical simulation equipment.
As a professional silicone manufacturer focusing on humanoid robot special materials, Hong Ye Jie insists on scenario‑based formula iteration and industrial pain point solving. We provide free sample testing, customized formula adjustment and stable global bulk supply services, helping overseas bionic customers improve product dynamic performance, extend service life and enhance market competitiveness.
