Solve Oil Stain Problems of Interactive Robot Bionic Skin

With the rapid popularization of commercial humanoid robots worldwide, shopping mall guide robots, front desk reception robots and science museum exhibition robots have become mainstream intelligent equipment. These robots need to shake hands, receive touch and interact closely with hundreds of visitors every day. The bionic silicone skin on palms, fingers and facial areas is exposed to continuous contact with human skin sebum, sweat oil and makeup oil.

Traditional ordinary liquid silicone has loose molecular gaps. Grease will slowly penetrate into the silicone interior after a period of contact, forming deep dark oil stains that cannot be wiped off with conventional cleaning agents. Many robot enterprises have to replace the whole piece of silicone skin frequently, which brings high after-sales maintenance cost and shortens the service cycle of robot outer skin. This oil contamination problem has troubled most bionic material R&D teams for a long time.

Shenzhen Hong Ye Jie Technology Co., Ltd was founded in 2006, with nearly 20 years of professional experience in silicone rubber R&D and manufacturing. We keep iterating human body silicone, liquid silicone rubber and other bionic silicone materials. In response to the oil-stain feedback from overseas robot customers, our R&D team optimized the silicone molecular cross-linking structure and developed this anti-sebum oil resistant robot skin silicone, enriching our functional bionic silicone product line.

Different from silicone products with temporary anti-fouling coating, the oil resistance of this new material comes from bulk molecular modification. The compact molecular structure effectively blocks the penetration of sebum and grease. Even after thousands of times of hand contact and repeated wiping, no deep oil stain will remain on the silicone surface, and the bionic skin keeps clean and bright for a long time. The hardness range is adjustable from 0A to 30A. Ultra-soft grades are available for facial and fingertip thin skin, while medium-soft grades fit wrist and elbow joint outer layers. Various human skin tones can be precisely color-matched to meet the bionic appearance requirements of different robot models.

The material has excellent molding adaptability. Moderate fluidity supports vacuum pouring for integrated forming, and also fits manual brush coating to produce ultra-thin curved skin, effectively reducing bubble and wrinkling defects. Adopting platinum addition curing technology, the formula contains no harmful substances and meets strict human skin contact safety standards. Apart from robot skin silicone, Hong Ye Jie provides a full set of supporting materials including silicone rubber, RTV silicone and foam silicone, so customers can finish all bionic material procurement in one stop. Our factory has obtained ISO9001 quality certification, and every batch of products will be tested for oil resistance, surface anti-fouling performance and mechanical properties to ensure consistent quality for mass export orders.

Overseas humanoid robot developers, intelligent equipment manufacturers and simulation model makers are warmly welcome to contact us for free samples and customized technical solutions. We can adjust the formula according to your robot’s daily contact frequency and working environment, and provide stable long-term bulk export supply, helping you cut down skin maintenance costs and keep the robot bionic skin clean and beautiful all year round.
