# LSR Facial Cleanser Charging Port Dust Plug
Manufactured by 橡楚（湖北）橡胶有限公司
---
The LSR Facial Cleanser Charging Port Dust Plug is a precision-molded custom sealing component manufactured by 橡楚（湖北）橡胶有限公司, designed exclusively to prevent dust, moisture, and cosmetic residue from entering the charging interface of electric facial cleansing devices. Fabricated from 100% pure food-grade liquid silicone rubber (LSR), this dust plug combines excellent elasticity, chemical resistance, and biocompatibility to meet the strict hygiene and durability requirements of personal care electronics.
Unlike conventional injection-molded solid silicone dust plugs, our LSR product is produced through precision liquid injection molding, enabling tight dimensional tolerances and consistent surface finishes that match the streamlined design of modern facial cleansers. It maintains a secure fit through thousands of insertion and removal cycles, without deforming, loosening, or losing sealing performance, addressing common pain points of inferior dust plugs such as easy falling off, material aging, and residue adhesion.
As a professional LSR products manufacturer based in No. 54, Neihe Lane, Fankou Sub-district, Economic Development Zone, Echeng District, Ezhou City, Hubei Province, China, we produce this dust plug with full compliance to ISO 9001 quality management systems, supporting custom sizes, hardness, and color matching to fit any brand of electric facial cleansing device.
Our dust plugs are produced via precision LSR injection molding with the following controlled process parameters to ensure consistent quality:
All raw materials used for our LSR facial cleanser dust plugs are sourced from reputable global silicone suppliers, and the finished product complies with both Chinese food contact material standards and U.S. FDA food contact requirements. It is non-toxic, odorless, and free of BPA, phthalates, and other harmful additives, making it safe for long-term use on personal care devices that come into direct contact with facial skin. Unlike low-cost recycled silicone plugs, our LSR product will not leach harmful substances even when exposed to warm bathroom environments.
Addition-cured liquid silicone rubber has far better compression set resistance than conventional condensation-cured solid silicone. Our dust plugs maintain their original shape and tight fit after more than 5,000 insertion and removal cycles, avoiding the common problem of loose sealing and falling off caused by material fatigue. It effectively blocks fine dust from the bathroom, moisture from showering, and residual facial cleanser or moisturizer from entering the charging port, preventing short circuits, contact corrosion, and extending the service life of the electric facial cleansing device.
Our in-house precision LSR injection molding capability supports custom production for almost all types of facial cleanser charging ports on the market, including rectangular, oval, and rounded interface designs. We can match any color requirement to align with your device's exterior design, from matte to semi-gloss surface finishes. Tight dimensional tolerances ensure the dust plug fits flush with the device body, maintaining the streamlined aesthetic of your product without adding bulk.
The LSR material we use has excellent inertness to common skincare ingredients including facial cleansers, toners, moisturizers, and exfoliating acids. It will not swell, crack, or degrade after long-term contact with these substances, outperforming ordinary rubber and thermoplastic elastomer (TPE) dust plugs that often degrade within 6 to 12 months of use.
The LSR Facial Cleanser Charging Port Dust Plug is a dedicated sealing component for the personal care electronics industry, with core application scenarios including:
In daily use, it provides continuous protection for the charging port: during use and storage in the bathroom, it blocks moisture, soap scum, cosmetic residue, and dust from accumulating inside the charging interface; during travel, it prevents lint from toiletry bags from entering the port, avoiding poor contact caused by foreign object buildup. For waterproof facial cleansing devices designed for use in the shower, the LSR dust plug is an essential component to maintain the product's waterproof rating throughout its service life.
We recommend different hardness based on your product design requirements:
