Silicone solutions for LED lighting systems

Today’s elastomer market presents an extensive range of rubbers available to lighting engineers, designers and buyers. With so much choice on offer, it is imperative to select the correct specification of rubber with suitable grades, forms and thickness to ensure application performance.

Silicone rubber, with its superb sealing properties, ability to withstand high temperatures and lightweight features makes it the material of choice for both indoor and outdoor LED lighting applications.

Selecting the right material for LED lighting applications is crucial, as significant downtime and repair costs can occur if electrical enclosures fail to keep out water, moisture or dust ingress. Our material engineering specialists have developed a high-performance closed cell silicone sponge which boasts many protective properties including heat and weathering resistance.


How can silicone be used?

Silicone sponge is used in a variety of applications but generally its purpose is to seal, insulate or protect an application from flame, heat, water, dust or general weathering.

Why choose silicone rubber for LED lighting?

Silicone rubber boasts a host of properties which make it an ideal solution for LED lighting systems. Silicone rubber can withstand extremely high temperatures up to 230°C, making it a perfect choice for high heat resistant lighting. It also has great performance in sub-zero conditions and stays flexible to -60°C. Our closed cell silicone sponge boasts excellent protective properties, capable of meeting IP ratings 1P66 and IP67, ensuring sealing to the very highest standards, low water absorption and low risk of water and dust ingress.

Extreme Temperature Resistance

Silicone rubber boasts extreme temperature resistance from 230°C to -60°C together with chemical stability and low compression set. Performing comfortably with high heat generated from the diodes and being able to stay flexible in sub-zero temperatures, silicone is a highly reliable and robust choice for a cast range of LED lighting projects.


Silicone rubber is the ideal choice for LED lighting applications due to its superb sealing properties. It prevents water, moisture or dust ingress from occurring within electrical enclosures, making it a reliable and high-performing option.


Silicone is a highly-robust material offering excellent environmental resistance from ozone, oxidation, ultraviolet light, corona discharge, cosmic radiation, corona discharge, ionising radiation and general weathering.
