# Liquid Silicone Waterproof Gasket for Industrial Lamps

Liquid Silicone Rubber (LSR) waterproof gaskets for industrial lamps, designed specifically for sealing and buffering applications in high-power industrial and mining lighting fixtures. Manufactured by 橡楚（湖北）橡胶有限公司 (Xiangchu (Hubei) Rubber Co., Ltd.) at our dedicated production 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, these custom-molded LSR components deliver reliable long-term performance in harsh industrial environments.
Industrial and mining lighting fixtures require consistent protection against moisture, dust, vibration, and temperature fluctuation to avoid premature failure and safety hazards. Our LSR waterproof gaskets integrate two core functions: creating a permanent IP-rated waterproof barrier between lamp housing components, and absorbing mechanical vibration and impact to protect fragile light sources, drivers, and optical components. Unlike cut gaskets made from solid silicone sheets, our injection-molded LSR gaskets feature uniform density, consistent dimensional tolerance, and no material waste from cutting, making them ideal for mass production of standard and custom industrial lighting fixtures.
All our gaskets are produced from 100% virgin low-volatility LSR raw material, with no recycled rubber content, ensuring consistent chemical and physical performance across every production batch. We can produce custom-shaped gaskets and cushioning components to match any standard or custom industrial mining lamp design, from small 50W portable fixtures to large 1000W fixed high-bay mining lamps.

Our LSR gaskets are manufactured via high-precision liquid injection molding (LIM), with the following process controls:
---
LSR inherently resists water, ozone, dust, and common industrial chemical contaminants (including weak acids, weak alkalis, and mineral oils). Unlike organic rubber gaskets that crack, shrink, or degrade after prolonged exposure to outdoor or underground conditions, our LSR gaskets maintain elastic recovery and sealing force for over 10 years of continuous use, preventing water ingress that causes short circuits and lamp failure. The low compression set of our LSR material ensures that the gasket maintains consistent pressure between mating lamp housing components even after long-term temperature cycling, eliminating the need for re-torquing or replacement during the fixture's service life.
Industrial and mining sites are prone to continuous mechanical vibration from mining equipment, heavy machinery, and vehicle traffic. Our LSR gaskets combine controlled hardness and excellent damping properties to absorb high-frequency vibration and impact, preventing loose connections, cracked lenses, and damage to LED chips or driver components. This buffering effect extends the overall service life of industrial lighting fixtures by 20–30% compared to unbuffered hard seal designs.
Our LIM manufacturing process allows for fast, low-cost tooling for custom-shaped gaskets, including round, square, rectangular, and irregular designs with integrated mounting holes, notches, or multi-level profiles. We can adjust material hardness and thickness to match specific sealing and buffering requirements, from thin sealing gaskets for flat housing joints to thick cushioning pads for mounting light sources. This flexibility makes our gaskets suitable for all types of industrial and mining lamps, including roadway lighting, high-bay workshop lighting, underground tunnel lighting, and portable mining work lamps.
Our addition-cured LSR raw material is free of nitrosamines, phthalates, heavy metals, and other restricted hazardous substances, meeting the requirements of RoHS 2 and REACH regulations for industrial products. The low volatile content of our material ensures no outgassing that can fog lamp lenses or reduce light transmittance over time, maintaining consistent lighting output throughout the fixture's service life.

Our Liquid Silicone Waterproof Gaskets for Industrial Lamps are purpose-designed for sealing and buffering in the following industrial and mining lighting use cases:
In these applications, our gaskets perform two core functions: they create a waterproof and dustproof seal that meets IP65, IP66, and IP67 ingress protection requirements, and they absorb vibration to prevent component damage in high-vibration environments.

We produce gaskets for all common industrial lamp sizes, from 50 mm diameter gaskets for small 30–100W fixtures to 500 mm diameter gaskets for 500–1000W high-power high-bay lamps. We also produce custom-sized gaskets to match your fixture design, with lead times for new tooling typically between 7–15 working days for standard mold sizes. We recommend providing 2D CAD drawings or physical samples for custom gasket quotes.
All our LSR gaskets are produced from food-contact compliant raw material as standard. For most general industrial applications, our standard low-volatility grade is sufficient. For applications requiring higher low-temperature flexibility (for use in cold underground mines or high-altitude environments), we offer a modified low-temperature grade that retains elasticity down to -55°C.
