Silicone Seals for LED Lighting & Electronics: Waterproofing, Shielding, & Long-Term Reliability

LED lighting and electronic devices face unique sealing challenges: from outdoor LED fixtures needing IP67/IP68 waterproofing to industrial enclosures requiring EMI shielding. Our custom silicone extruded gaskets and seals are designed to protect these devices from environmental damage and electromagnetic interference, ensuring consistent performance in indoor and outdoor applications.

1. Essential Applications in LED & Electronics Industries

• Outdoor LED Fixtures: A North American LED lighting brand uses our co-extruded silicone gaskets with 3M adhesive for their IP67-rated streetlights and landscape fixtures. The dual-material design combines a flexible silicone seal (for waterproofing) with a strong adhesive backing (for easy, permanent installation), preventing water intrusion and extending fixture lifespan.
• Electronic Enclosures & Cabinets: Our EMI shielding silicone gaskets (infused with conductive particles) are used in industrial control panels and telecom equipment. These seals block electromagnetic interference (EMI) from nearby devices, ensuring signal integrity while providing dustproof and weatherproof protection for internal components.
• LED Driver Housings: High-temperature resistant silicone tubes seal LED driver compartments, protecting sensitive electronics from heat buildup (up to 200°C) and moisture. Custom hollow profiles allow for cable pass-through while maintaining a tight seal, reducing the risk of short circuits.

2. Why Silicone Is Ideal for LED/Electronic Sealing

• IP Rating Compliance: Custom profiles (such as U-channel or bulb seals) are engineered to achieve IP65–IP68 ratings, preventing water and dust ingress in outdoor or harsh industrial environments.
• EMI Shielding Capability: Conductive silicone options provide EMI/RFI shielding (up to 80 dB attenuation at 1 GHz), meeting the requirements of industrial and telecom standards.
• Temperature Stability: Performs from -40°C to 250°C, ensuring reliable sealing in both cold outdoor conditions and hot electronic enclosures.

3. Supporting LED & Electronics Innovation

We partner with LED and electronics OEMs to accelerate product development:

• Fast prototyping (3–7 days) allows for quick testing of seals in new fixture designs.
• Custom die-making (3–5 days) enables unique profiles for compact or irregularly shaped enclosures.
• Global logistics support ensures timely delivery of seals for production lines worldwide. Whether you’re designing a weatherproof LED wall pack or a shielded industrial control box, our custom silicone seals provide the protection your electronics need to perform reliably, even in the toughest environments.
