Low Friction Silent Bionic Silicone for Robot Skin

With the accelerated commercialization of humanoid robots worldwide, exhibition explanation robots, shopping mall guide robots and government reception robots have been widely deployed. These robots interact with visitors frequently, and soft bionic silicone skin is required on their fingers, wrists and moving joints. Traditional bionic silicone has a relatively high friction coefficient. Obvious rubbing sound occurs every time the joint bends and slides. The noise is particularly noticeable during close-range interaction, downgrading product quality and troubling many R&D teams for a long time.

Shenzhen Hong Ye Jie Technology Co., Ltd was founded in 2006 and has nearly 20 years of experience in R&D and manufacturing of silicone rubber. We keep upgrading human body silicone, liquid silicone rubber and other bionic materials. Responding to the noise feedback from the robot industry, our R&D team adjusted the silicone molecular structure and developed this low friction & silent robot skin silicone to enrich our bionic material portfolio.

Different from silicone products that rely on lubricant coating for noise reduction, the noise reduction capability of this product comes from bulk molecular modification. It delivers better friction durability and will not lose silent effect rapidly with surface abrasion. In thousands of cycles of reciprocating joint motion tests, the silicone contact surface maintains low-noise sliding performance, meeting the demand for long-time continuous demonstration of commercial robots. The hardness ranges from 0A to 30A for flexible adjustment. Matching hardness grades can be selected for facial skin, soft fingertip skin and joint skin, and various simulated skin colors are customizable.

It has excellent molding compatibility. Moderate fluidity fits vacuum pouring for integrated forming, and also supports manual brush coating for ultra-thin bionic skin. The material can closely attach to complex curved structures of robots and reduce defects such as bubbles and wrinkles. Adopting platinum addition curing system, the formula contains few harmful substances and is safe for direct human-robot contact. Apart from robot skin silicone, Hong Ye Jie provides a full range of supporting materials including silicone rubber, RTV silicone and foam silicone to satisfy material demands of bionic projects in one stop. Certified with ISO9001 quality system, every batch of our products will be sampled and tested for friction coefficient, noise performance and mechanical properties to guarantee stable mass production quality.
