Product Overview

Our LSR for Injection Molding Electronic Seals is a high-performance Addition Curing Silicone raw materials, specially formulated for injection molding of precision electronic seals. Composed of high-purity flowable Part A (base rubber) and Part B (curing agent), it solves the pain point of ordinary liquid silicone or Condensation Curing Silicone Mold Rubber with poor injection fluidity, low precision, and poor electrical insulation. Unlike standard Mold Making Silicone, it is optimized for injection molding processes, ensuring smooth filling of small electronic seal cavities, precise molding, and excellent compatibility with electronic components, making it ideal for precision electronic seals, connectors, and sensor gaskets.

Product Features & Advantages

1. Excellent Injection Moldability: Optimized viscosity for injection molding, smooth flow, easy filling of small and precise electronic seal cavities, no overflow, ensuring high molding precision, far superior to non-injection-grade liquid silicone.

2. High Sealing Precision: Low shrinkage rate (≤0.03%), precise dimension control, tight fit with electronic components, effective dustproof, waterproof, and anti-leakage, protecting electronic parts from damage.

3. Superior Electrical Insulation: High insulation performance (≥10¹² Ω·cm), safe for electronic components, avoiding short circuits and ensuring device stability.

4. Strong Durability: High tensile/tear strength, good elasticity, resistance to aging and chemicals, long service life, reducing seal replacement costs.

5. Efficient Operation: 1:1 mix ratio, compatible with industrial injection molding equipment; supports room/heat curing, adapting to mass production of electronic seals.

6. Flexible Customization: Hardness, viscosity, curing time, and color can be tailored to electronic seal specifications, matching different injection molding processes.

 

How to Use (Step-by-Step Injection Guide)

1. Mix Part A and Part B of the LSR in a 1:1 weight ratio, stirring thoroughly with industrial mixing equipment for 2~3 minutes until uniform and bubble-free, ensuring injection fluidity.

2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity and vacuum strength) to eliminate bubbles, preventing injection defects.

3. Pour the degassed LSR into the injection molding machine, set injection temperature (180~220℃) and pressure, and inject into electronic seal molds.

4. Cure at 80~120℃ for accelerated curing (tens of minutes) or room temperature (4~5 hours) for full curing.

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 for Injection Molding Electronic Seals is widely used in global electronic manufacturing, including precision electronic connectors, sensor gaskets, automotive electronic seals, circuit board seals, and electronic device waterproof seals. It also applies to Electronic Potting Compound auxiliary sealing and high-precision Prototype silicone for electronic components, bringing tangible value: improving injection molding efficiency by 40%+, reducing seal defect rates by 45%+, and helping B2B purchasers gain advantages in the electronic seal silicone market.
