Global humanoid robot industry is rapidly transferring from lab prototype to commercial application. A large number of service, reception and exhibition humanoid robots are deployed in exhibition halls, shopping malls and showrooms. These robots need long-time static display and frequent physical touch interaction with visitors, bringing new material requirements for bionic skin: not only realistic soft touch, but also stable appearance for long exhibition, comfortable touch experience and low maintenance cost.
Conventional bionic silicone generally suffers from free silicone oil migration. After a period of display, oil bleeds out to the surface, making silicone greasy and sticky. In dusty exhibition environment, sticky skin absorbs dust and hair quickly, losing realistic texture within months. Visitors get greasy residue on hands and clothes after touching robot skin, damaging user experience. Frequent cleaning and polishing will accelerate surface aging and damage painted texture. Robot manufacturers spend high labor cost on regular maintenance and renovation, limiting large-scale promotion of commercial humanoid robots.
Not only humanoid robots, museum display mannequins and premium wax figures also face oil bleed and dust accumulation problems. Static simulation props turn grey and mottled after long exhibition, failing to meet long-term display requirements. Global simulation industry is in urgent need of low bleed dry touch bionic skin material with realistic texture and long-term stability.
Targeting the pain points of commercial interactive robots and long-term exhibition simulation products, Shenzhen Hong Ye Jie Technology developed HYJ-RS-039 low bleed dry touch robot skin silicone with years of silicone purification and formula optimization experience. Raw material purification technology reduces free small molecule components inside formula and suppress oil migration fundamentally. The cured bionic skin surface stays dry and smooth, no greasy touch and low dust adsorption, greatly reducing cleaning workload and maintenance cost, perfectly matching combined working condition of frequent human touch and long static display.
While achieving low bleed dry performance, the material retains soft hand feel and dynamic properties required by bionic skin, with 0‑20 Shore A optional hardness. Ultra-soft grade for robot facial skin reproduces delicate skin texture, supports stretching of smile and frown micro-expression without tearing, and rebounds naturally after deformation. Medium soft grade for palm and torso interactive skin balances soft touch and surface wear resistance, suitable for visitor touch and hand grasping interaction. Low curing shrinkage ensures high-precision texture reproduction. Multiple custom skin tones are available with strong coating adhesion, preventing paint peeling and color fading on dry surface, keeping realistic appearance stable.
The formula adopts long-term anti-yellowing system, slowing yellowing and darkening under indoor lighting, extending service life of bionic skin and reducing renovation frequency. Platinum addition curing system is non-toxic and odorless with good biocompatibility, safe for direct human touch. Moderate fluidity improves finished product yield, compatible with pouring and brushing molding. It supports small batch sampling for R&D and large automated mass production with stable batch quality.
This low bleed dry bionic silicone is widely applied for exhibition reception robots, store service companion robots full-body outer skin, facial expression layer, interactive flexible palms; museum simulation mannequins, high-end art wax figures; long-term displayed film prosthetics, static & micro-dynamic medical simulation mannequins and cultural simulation props.
Shenzhen Hong Ye Jie Technology keeps focusing on material bottlenecks in humanoid robot commercialization, continuously iterating bionic skin silicone with differentiated performance including high tear resistant joint grade, outdoor weather resistant grade, matte anti-fingerprint grade and this low bleed dry interactive grade, providing scenario customized silicone solution for different working conditions. We offer free sample testing, adjustable hardness and skin tone, full technical guidance for mold and molding process, stable delivery for small and bulk orders, helping global commercial humanoid robot and high-end simulation cultural industry achieve commercialization steadily.
