ultra-low modulus ultra-soft high-flexibility dynamic bionic skin silicone is a new high-end refined platinum-cured RTV-2
liquid silicone launched by Shenzhen Hong Ye Jie Technology, targeting the core pain points of stiff micro-expressions, dynamic lag, high deformation stress and rigid mechanical sense of high-end emotional humanoid robots. Conventional bionic silicone adopts high-modulus rigid molecular structure with large deformation resistance, which can only adapt to large-amplitude joint movements but cannot restore subtle facial micro-dynamics. High-modulus silicone causes unresponsive fine movements, single expression layers and obvious mechanical stiffness, failing to meet the ultra-realistic simulation standards of high-end AI emotional robots and live broadcast robots. Long-term high-frequency micro-deformation will lead to internal stress accumulation, gradual skin hardening and dynamic performance attenuation, increasing equipment operation load and wear loss. This product adopts upgraded flexible molecular chain reconstruction technology to greatly reduce deformation stress and dynamic resistance, perfectly solving the fine dynamic stiffness defect of traditional robot skin and filling the market gap of high-end refined emotional bionic materials.
It adopts stable 1:1 weight ratio mixing, room temperature curing and heating accelerated curing, compatible with precision pouring and fine brushing processes, suitable for integrated molding of robot full-face fine skin, eye dynamic layers, mouth expression layers and neck flexible deformation layers. The hardness ranges from 3A to 18A to meet high-precision differentiated simulation needs. 3-10A ultra-low modulus grade is dedicated to ultra-fine micro-expression areas such as face, eyelids and lips, realizing zero-stiffness synchronous response to millimeter-scale subtle movements. 11-18A flexible high-toughness grade adapts to neck and cheek soft deformation areas, balancing delicate dynamic fluency and structural stability, perfectly adapting to all-weather high-precision emotional interaction working conditions.
The core advantage lies in ultra-low modulus low-stress deformation + ultra-soft flexibility + zero-stiffness micro-expression. Different from ordinary high-modulus silicone with rigid deformation and stiff dynamics, this material features human-skin-like flexible mechanical properties with minimal deformation resistance and uniform stress release. Subtle facial adjustments such as eyebrow lifting, blinking and mouth corner micro-movements can be responded synchronously with rich expression layers and smooth dynamic transition, without mechanical stuttering or rigid stretching. After tens of thousands of high-frequency micro-deformation fatigue tests, the material maintains permanent flexibility without stress accumulation or dynamic aging, keeping the robot’s micro-expressions delicate and vivid for long-term operation.
With ultra-low curing shrinkage rate ≤0.07%, the material accurately restores ultra-fine human skin pores, shallow delicate textures and natural soft lines, presenting superior realistic static texture without plastic stiffness or heavy cortex sense. The upgraded flexible color fastness formula ensures stable color performance without yellowing, darkening or mottling during long-term subtle cyclic deformation. It retains excellent flexible tear resistance and micro-fatigue resistance, with no cracking, peeling or fading in long-term fine dynamic operation, balancing top-level ultra-realistic texture and long-term dynamic stability.
The low-stress dynamic adaptation is optimized for high-end precision robot structures, effectively reducing equipment driving load and precision component wear, lowering long-term failure rate and maintenance cost of high-precision emotional robots. The tightly fitted skin structure ensures uniform thickness and zero hollowing, realizing zero-lag synchronous dynamic response without movement disconnection. Adopting high-purity medical-grade platinum eco-friendly curing system, the silicone is non-toxic, odorless and skin-friendly with excellent biocompatibility, safe for high-end close human-computer interaction, ultra-realistic boutique display and AI live broadcast commercial scenarios. It has moderate fluidity and smooth defoaming performance, producing flawless high-precision finished products with uniform flexibility and consistent micro-dynamic performance, suitable for high-end robot customized R&D and boutique mass production with stable batch consistency.
Shenzhen Hong Ye Jie Technology has formed a full-differentiated bionic silicone matrix covering wear resistance, weather resistance, high resilience, high tear resistance, matte texture, zero-bleed dry touch and this new ultra-low modulus flexible micro-expression type. We support customized ultra-realistic skin tone, precise modulus adjustment and micro-dynamic performance enhancement, providing free sample testing and full-process refined technical guidance, helping global high-end emotional robot and ultra-realistic simulation industries upgrade micro-dynamic fineness and human-like simulation accuracy.

Operating Instructions
Fully stir Part A and Part B before use to evenly disperse ultra-low modulus flexible fillers and ensure uniform dynamic flexibility. Mix strictly at 1:1 weight ratio and stir thoroughly by scraping bottom and walls to avoid local stiffness and inconsistent dynamic response. Vacuum defoaming is required to ensure flawless fine skin surface and smooth micro-dynamics. Room temperature pot life is 45-55 minutes, full curing for 6-10 hours. Heating curing at 60-80℃ accelerates mass production without damaging core low-stress flexible performance.
Notes
Platinum silicone will be poisoned and fail to cure when contacting sulfur, tin, lead and phosphorus contaminants, resulting in flexibility attenuation and skin hardening. All tools and molds must be clean and dry without oil pollution. Adopt high-precision pouring process for facial fine molding to ensure uniform skin thickness. Avoid long-term high-temperature exposure to prevent flexible molecular aging. Complete micro-dynamic response test before commercial application of high-precision robot products.
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, oil and chemical pollutants, avoid long-term strong light exposure. Shelf life: 12 months, transported as non-dangerous goods.
