HONGYE SILICONE’s LSR Material for Seals and Gaskets is a premium dual-component addition curing Liquid silicone rubber, tailored for global B2B purchasers in industrial sealing, automotive, electronic, and medical sealing scenarios. As a national high-tech enterprise with standardized production and one-stop solutions, this LSR material features excellent sealing performance, high elasticity, wide temperature resistance, and chemical resistance. It supports room/heat curing, deep curing without thickness limits, and flexible customization, helping purchasers produce durable, leak-proof seals and gaskets, reduce replacement costs, and meet strict industrial sealing standards.
Product Overview
Our LSR Material for Seals and Gaskets is a high-performance Addition Curing Silicone raw materials, composed of high-purity flowable Part A (base rubber) and Part B (curing agent), specially formulated for sealing and gasket manufacturing. Unlike ordinary liquid silicone or Condensation Curing Silicone Mold Rubber, it solves the pain points of poor sealing, low elasticity, and short service life in harsh working environments. As a professional supplier, we provide standardized production to ensure stable batch quality, making it ideal for manufacturing high-performance seals and gaskets for automotive, electronic, medical, and industrial equipment.

3. High Durability: High tensile/tear strength, elongation at break ≥500%, service life ≥5 years, reducing seal replacement frequency and costs.
4. Safe & Compliant: FDA and RoHS certified, non-toxic, odorless, no harmful by-products, suitable for medical and food-contact sealing scenarios.
5. Easy Industrial Operation: 1:1 mix ratio, simple stirring for 2~3 minutes, compatible with industrial molding equipment; supports room/heat curing, adapting to mass production.
6. Flexible Customization: Hardness, elasticity, curing time, and color can be tailored to different sealing needs (automotive, electronic, medical), ensuring perfect fit.
How to Use (Step-by-Step Production Guide)
1. Mix Part A and Part B of the LSR material in a 1:1 weight ratio, stirring thoroughly with industrial equipment in an irregular direction for 2~3 minutes until uniform and bubble-free, ensuring sealing performance.
2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity and vacuum strength) to eliminate bubbles, preventing seal defects.
3. Pour the degassed LSR into seal/gasket molds, leveraging good fluidity to fill all details and gaps, ensuring uniform thickness.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing to meet industrial production efficiency.
5. Store unused LSR in sealed packaging, separate Part A and Part B, indoor storage away from sunlight and rain, use within 10 months; avoid contact with N, P, S-containing compounds to prevent curing failure.
Application Scenarios
Our LSR Material for Seals and Gaskets is widely used in global industrial fields, including automotive seals (engine gaskets, door seals), electronic gaskets (circuit board seals), medical equipment seals, industrial equipment gaskets, and liquid tank seals. It is also suitable for Food grade mold silicone sealing accessories and Electronic Potting Compound auxiliary sealing, bringing tangible value: reducing seal replacement costs by 40%+, improving equipment reliability by 50%, and helping B2B purchasers gain advantages in the global sealing material market.
