# LSR Waterproof Seal Ring For Facial Cleanser
---
The LSR Waterproof Seal Ring for Facial Cleanser is a precision-molded liquid silicone rubber component designed to provide long-lasting, reliable water resistance for electric facial cleansing devices. Manufactured by 橡楚（湖北）橡胶有限公司 at our facility in 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, this seal ring is engineered to meet the demanding daily use requirements of personal care electronics, balancing flexible conformability, low compression set, and compatibility with common skincare ingredients.
As a specialized manufacturer of liquid silicone rubber (LSR) products, we focus on producing consistent, high-quality seals tailored to the compact geometry of modern facial cleansers. Unlike generic rubber seals, our LSR waterproof seal rings are manufactured through injection molding, enabling tight dimensional tolerances and uniform material properties that prevent water ingress into sensitive electronic components, even after repeated exposure to tap water, facial cleansers, and warm cleansing temperatures.
This product is ideal for brands developing waterproof facial cleansing devices rated from IPX5 to IPX7, providing a cost-effective sealing solution that retains performance through thousands of use cycles.

Our LSR waterproof seal rings are produced from food-contact grade platinum-cured liquid silicone rubber, with the following core material properties:
Finished seal rings meet the following physical performance standards for personal care applications:
All our seal rings are produced via precision LSR injection molding with controlled processing to ensure consistency:

The addition-cured LSR material used in our seal rings has excellent compression resistance, retaining its elastic recovery properties even after prolonged compression in the facial cleanser housing. This prevents the seal from deforming or losing its sealing force over time, avoiding water leakage that would damage the device's internal battery and circuit board. Unlike cheaper peroxide-cured silicone seals, our platinum-cured LSR does not leach volatile byproducts that could cause unpleasant odors or skin irritation.
All raw materials used for our facial cleanser seal rings are selected to meet food-contact and skin safety requirements. The non-toxic, non-irritating silicone material will not cause allergic reactions when it comes into accidental contact with facial skin during use, and it does not support bacterial growth with regular cleaning. It is also resistant to discoloration from contact with common facial cleanser ingredients, maintaining a clean appearance throughout the device's service life.
Modern electric facial cleansers are designed to be lightweight and handheld, requiring small, dimensionally accurate seal rings to fit into tight housing gaps. Our precision injection molding process achieves tight tolerances that eliminate gaps between the seal and device components, ensuring consistent water resistance across every production batch. We can also customize the cross-sectional shape (including O-ring, lip seal, and custom profile designs) to match your specific device design.
Our LSR seal rings maintain their performance through repeated exposure to warm water, facial cleansers, and mild exfoliating ingredients, with no swelling, hardening, or cracking over time. The material's stable chemical properties mean it will not degrade even with regular daily use, extending the service life of your facial cleansing device.
