# Medical Liquid Silicone Lens Protective Sleeve
*Manufactured by 橡楚（湖北）橡胶有限公司*

The Medical Liquid Silicone Lens Protective Sleeve is a custom-molded precision component manufactured by 橡楚（湖北）橡胶有限公司, designed to protect sensitive optical lenses in medical diagnostic and surgical imaging equipment. Produced from high-purity medical-grade liquid silicone rubber (LSR) through precision injection molding, this product combines excellent biocompatibility, optical stability, and mechanical flexibility to meet the stringent requirements of the global medical device industry.
Our lens protective sleeves are engineered to form a tight, non-slip seal around optical lens assemblies, preventing dust, moisture, bodily fluids, and other contaminants from compromising image clarity or damaging delicate lens surfaces. Unlike generic rubber or plastic protective components, our LSR formulation maintains consistent performance across repeated sterilization cycles and extreme operating temperatures, making it suitable for both single-use disposable and reusable medical device applications. At 橡楚（湖北）橡胶有限公司, we manufacture all our LSR products at our facility 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, with full process control from raw material mixing to final inspection to ensure every component meets medical industry quality standards.

All our Medical Liquid Silicone Lens Protective Sleeves are produced from virgin, medical-grade LSR with no recycled content or harmful additives. Key material properties are as follows:
Consistent mechanical performance is critical for protective lens components used in medical equipment. Our product meets the following physical specifications:
Our precision injection molding process ensures tight dimensional tolerances and consistent surface finish for all lens protective sleeves:
---
Our lens protective sleeves use only platinum-cured LSR that meets international biocompatibility standards, eliminating the risk of residual toxic byproducts common in lower-grade peroxide-cured silicones. The non-porous surface prevents bacterial adhesion, making it easy to clean and sterilize for repeated clinical use, and safe for short-term and long-term contact with patient tissue when used as part of approved medical devices.
We use custom precision molds engineered to match your exact lens assembly dimensions, ensuring a snug, gap-free fit that does not interfere with light transmission or lens focusing. Unlike machined or extruded protective components, our injection-molded LSR sleeves have consistent wall thickness and no flash or burrs that could cause misalignment of optical components. The material has consistent refractive index that can be tuned to meet specific optical requirements for semi-transparent protective sleeve applications.
Our LSR formulation retains its flexibility, mechanical strength, and dimensional stability after more than 100 cycles of standard autoclave sterilization, with no cracking, hardening, or discoloration. This extended service life reduces replacement costs for reusable medical equipment, compared to lower-grade rubber or plastic components that degrade quickly with repeated sterilization.
We can manufacture Medical Liquid Silicone Lens Protective Sleeves in any custom size, shape, hardness, and color to match your specific equipment design requirements, from small endoscope camera lenses to large surgical microscope objective lenses. We also offer optional secondary processing including adhesive bonding, surface treatment for improved anti-fog performance, and custom cutouts for mounting hardware.
