# Medical Grade Liquid Silicone Contact Pad
Manufactured by 橡楚（湖北）橡胶有限公司

Medical Grade Liquid Silicone Contact Pad (hereafter referred to as the LSR contact pad) is a precision-molded silicone product manufactured by 橡楚（湖北）橡胶有限公司 from low-volatility, biocompatible liquid silicone rubber (LSR) specifically designed for repeated skin and soft tissue contact in medical and healthcare settings. Unlike general-purpose rubber contact pads, our product is formulated to meet strict biocompatibility requirements for long-term or repeated skin contact, with excellent softness, non-slip grip, and resistance to repeated sterilization cycles.
Our LSR contact pads are produced via injection molding of raw platinum-catalyzed liquid silicone rubber, eliminating the residual cross-linking byproducts common in condensation-cured silicones. They maintain consistent physical performance across a wide temperature range, do not leach harmful additives into biological tissues, and resist staining, bacterial colonization, and degradation from repeated exposure to common medical disinfectants. This product is developed to meet the core needs of medical device manufacturers, clinical care institutions, and rehabilitation equipment suppliers for a reliable, safe contact interface between hard medical equipment and human tissue.
橡楚（湖北）橡胶有限公司 is located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, and specializes in the production of custom and standard LSR products for industrial and medical applications, with strict raw material incoming inspection and in-process quality control to ensure every batch of contact pads meets consistent biocompatibility and performance standards.

For custom-sized and shaped contact pads, our standard production parameters are:

All raw materials used for our medical grade LSR contact pads are sourced from certified LSR suppliers with pre-tested biocompatibility, and we do not add any unapproved processing agents or plasticizers during production. Unlike natural rubber pads, our product is entirely latex-free, eliminating the risk of latex allergic reactions for patients and healthcare workers. The low-volatility formulation prevents leaching of organic compounds onto skin or medical devices, meeting the basic safety requirements for prolonged contact with intact skin.
Platinum-catalyzed LSR has inherently better thermal and chemical stability than organic rubber or condensation-cured silicone. Our contact pads resist cracking, hardening, or discoloration after more than 500 cycles of 121°C autoclave sterilization, outperforming general-purpose silicone pads that often degrade after 100–200 cycles. They are also resistant to corrosion from common medical disinfectants including quaternary ammonium compounds, chlorhexidine, and isopropyl alcohol, maintaining non-slip performance and physical integrity for long-term use.
We offer a full range of hardness options from 10 Shore A (extra soft for pressure redistribution) to 50 Shore A (firmer for structural support) to match different application requirements. The non-porous surface of LSR provides consistent non-slip grip without using adhesive coatings, so the pad stays firmly in place on both device surfaces and skin without leaving residue. The soft, conformable nature of LSR allows the pad to adapt to body contours, reducing pressure points and improving patient comfort during long-term use.
Unlike open-cell foam or porous rubber materials, LSR has a fully closed, non-porous surface that does not absorb bodily fluids, ointments, or disinfectants. This makes the pad easy to clean and disinfected thoroughly, and significantly reduces the risk of cross-contamination and bacterial colonization between uses, a critical advantage for reusable medical equipment.
