Low Friction & Silent Robot Skin Silicone

HY-E630...
This two-component liquid silicone rubber is specially developed for moving joint and contact surfaces of robot fingers. It delivers outstanding low friction and silent performance. When robot joints bend and stretch repeatedly, the friction noise between silicone contact surfaces is extremely low, avoiding abnormal sounds that disturb interaction scenarios. It can be molded by pouring and brush coating, fits curved bionic skin of robots perfectly. Ideal for exhibition and commercial service humanoid robots to bring quiet and comfortable interactive experience.

Product Overview

Founded in 2006, Shenzhen Hong Ye Jie Technology Co., Ltd launches this low friction & silent robot skin silicone, a high-performance grade within our human body silicone product line. Modified formula reduces the surface friction coefficient of this robot skin silicone, solving the common abnormal noise issue caused by silicone friction during joint movement of humanoid robots. Besides robot skin silicone, we supply silicone rubber, RTV silicone, foam silicone and liquid silicone rubber, and provide stable supply for robot integrators and bionic R&D enterprises worldwide.

Technical Specifications

  1. Two-component platinum cured liquid silicone rubber, mixing ratio A:B=1:1, curable at room temperature or heating;
  2. Excellent low friction property, low sliding friction noise during reciprocating movement for quiet joint operation;
  3. Adjustable hardness from 0A to 30A, highly simulated human skin touch;
  4. Moderate fluidity, suitable for vacuum pouring and thin-layer brush coating;
  5. Working temperature range: -65℃~200℃, stable performance after repeated friction;
  6. Custom skin tones and solid colors are available.

Product Features

  1. Core low friction & silent performance: Molecular modification reduces surface friction coefficient. Faint friction sound during repeated bending and sliding of robot joints, eliminating harsh abnormal noise in interaction.
  2. Realistic bionic touch: Soft texture, close to real human skin, combining bionic appearance and quiet operation.
  3. Strong molding adaptability: Controllable fluidity, suitable for making thin bionic skin on complex curved surfaces such as robot faces, fingertips and joints, less prone to bubbles.
  4. Platinum eco-friendly system: Free of heavy metals and harmful additives, safe and non-irritating for long-term human contact.
  5. Stable friction durability: The silent effect will not decay rapidly after long-time repeated friction for longer service life.

How to Use

  1. Stir component A and component B separately until uniform;
  2. Mix A and B strictly at 1:1 weight ratio and stir evenly for 2–3 minutes;
  3. Perform vacuum degassing after mixing to remove internal air bubbles;
  4. Complete pouring or brush coating within the operating time, then wait for full curing;
  5. Demold to obtain finished low friction silent bionic robot skin.

Application Scenarios

Bionic skin for moving joints of humanoid robots, palm and finger skin of commercial reception robots, outer skin of exhibition interactive robots, surface layer of bionic manipulators, simulation mannequin skin, and all bionic interactive parts where friction noise needs to be avoided.

Value to Buyers

Abnormal friction noise of silicone on joints will greatly reduce user experience when commercial robots interact and demonstrate. This low friction silent robot skin silicone targets the noise pain point, ensuring quiet operation of robots and upgrading product quality. Hong Ye Jie supports free samples and technical guidance for molding process to shorten your R&D and verification cycle.

FAQ

Q1: Will the silent performance degrade after a period of use? A1: The silent feature comes from bulk material modification instead of surface coating. The silent performance remains stable under long-term reciprocating friction. Q2: Can this material be brush-coated to make ultra-thin robot skin? A2: The viscosity is optimized, which is very suitable for thin-layer brush coating to produce thin bionic skin. Q3: Is the material safe for human contact? A3: Platinum curing system without harmful additives, suitable for interactive scenarios with long-term hand contact. Q4: Can custom skin tones be formulated? A4: We support color matching for various human skin tones and special custom colors.
