LSR (Liquid Silicone Rubber) LED gasket buffer components are custom-molded sealing and cushioning parts designed specifically for LED lighting assemblies to address common industry challenges including moisture ingress, dust contamination, vibration damage, and thermal stress. At 橡楚（湖北）橡胶有限公司, 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, we formulate and mold these components from high-purity raw liquid silicone rubber to meet the strict performance requirements of indoor and outdoor LED lighting systems.
Unlike traditional gasket materials such as neoprene, EPDM, or solid silicone, LSR offers unique combinations of long-term weather resistance, low temperature flexibility, and compression set resistance that make it ideal for the extended 50,000+ hour service life expectations of modern LED products. Our LSR LED gasket buffer components serve two core functions simultaneously: they create a reliable environmental seal to protect sensitive LED driver electronics and diode arrays, and they provide controlled cushioning to absorb mechanical vibration and shock during transportation, installation, and long-term operation.
All our components are manufactured in our facility in Ezhou, Hubei, with tight dimensional tolerances to fit standard and custom LED housing designs, and can be formulated to meet specific application requirements from low-temperature outdoor installations to high-heat high-power LED arrays.
Our LSR LED gasket buffer components are produced from addition-cure liquid silicone rubber, with the following core material properties:
Finished component performance meets the following consistent specifications:
All our LSR LED gasket buffer components are produced via precision liquid injection molding (LIM), with the following process controls:
LSR inherently resists UV degradation, ozone attack, and temperature cycling that cause traditional gasket materials to crack, harden, or shrink over time. Our components maintain consistent compression set resistance for the full service life of LED products, preventing seal failure that would lead to LED corrosion or short circuits from moisture ingress. This long-term stability reduces maintenance costs for outdoor LED installations such as street lighting and facade lighting.
LSR’s consistent elastic properties provide predictable cushioning that absorbs vibration from wind, traffic, or nearby mechanical equipment for outdoor LED installations, and reduces vibration transfer from mounting surfaces for indoor industrial LED lighting. This prevents loosening of mounting hardware and damage to sensitive LED diode bonds, reducing early failure rates of finished lighting products.
Our liquid injection molding process enables the production of complex custom profiles, thin sections, and integrated features that cannot be achieved with solid silicone extrusion or cutting. Whether you need a frame gasket for a rectangular LED panel, an O-ring gasket for a round downlight, or a custom-shaped buffer for a high-power heat sink assembly, we can mold components to match your exact design requirements with tight dimensional tolerances.
LSR is an inherently non-conductive material, eliminating the risk of short circuits in LED driver and diode assemblies even in high-humidity environments. Our standard formulations also offer moderate thermal stability, allowing continuous operation at the typical operating temperatures of high-power LED products without performance degradation.
Our LSR LED gasket buffer components are suitable for a wide range of LED lighting applications across multiple industries:
Choosing the correct Shore A hardness depends on your assembly design and performance requirements:
We offer both standard-sized components for common LED housing dimensions and fully custom molding to match your unique product design. Standard sizes are available for common 120mm × 120mm LED panels, 6-inch downlights, and 1-meter linear LED strips. For custom projects, we accept 2D CAD drawings or 3D STEP files to produce components matching your exact dimensions.
We offer two core material grades for different application requirements:
At 橡楚（湖北）橡胶有限公司, we maintain a strict quality management system certified to ISO 9001 standards, with in-process quality checks at every stage of production from raw material incoming inspection to finished component dimensional verification. Each batch of LSR LED gasket buffer components undergoes performance testing for hardness, compression set, and dimensional accuracy before shipment to ensure consistent performance.
All our products comply with international RoHS requirements for restricted substances, and we provide material test reports with every batch upon request. For custom orders, we can provide prototype samples for your functional testing before full production to ensure the components meet your application requirements.
