Sealing Materials For Lighting

Effective sealing materials for lighting are essential for preventing dust or moisture from seeping into a lighting component. Any seepage could cause the component to suffer from damage or even failure, often resulting in costly replacement fees. At CB Frost, we ensure that we carefully choose the appropriate enclosure and gasket materials for the relevant seal design to ensure that the seal is effective for a long period of time.

Each type of material offers different qualities, properties and characteristics which result in different sealing capabilities whilst able to achieve an IP rating of IP66 and IP67 (Subject to sounds design).

When selecting the optimum material for a lighting seal, the following points must be taken into consideration:

Compressibility
Environmental exposure
Sealing effectiveness
Outgassing levels
Non-fogging capability

A variety of materials can pose a variety of problems. That’s where CB Frost’s expertise comes into play. We are aware of outgassing issues including Sulphur from various materials as well as adhesive problems when using acrylic based solutions. Even in extreme conditions our knowledge and experience gained from such projects as:

Quality without compromise

CB Frost was founded in 1921 in Birmingham, UK. Whilst we have seen so many changes in the last century, one thing that has always remained the same is our commitment to provide ‘quality without compromise’.

Who we are
Rubber and plastics specialists

CB Frost supplies an extensive range of high performance rubber, sponge, foam and plastic materials. With our technical knowledge and manufacturing expertise, we are here to advise on material selection to best suit your requirements.

Who we are
Experts in our field

As experts in our field, we have worked on a wide range of major projects, including the Chernobyl Sealing project, Crossrail, and Rail Floating Floor. Our expertise has also led to partnerships with Rogers’ Corporation and Armacell.

Who we are

Some of our most commonly used sealing materials for lighting are:

BISCO™ Silicones and Poron Urethanes™

At CB Frost, we commonly utilise BISCO Silicones and PORON Urethanes as lighting gasket materials as they are already certified for use under a range of standards. The fact that the materials already have the relevant certification means that the screening process can be simplified, as it removes the need to test each individual material used within the component.

Manufactured parts which include BISCO Silicones and PORON Urethanes should continue to perform to a high standard even after constant and repeated deflection, meaning that sealing integrity should always be maintained.
