At Kewell Converters we provide a range of industrial closed cell foam to suit any number of applications and requirements. These are the kind of foams that are commonly used for protective packaging, case inserts and other industrial safety components. Our foams are regularly checked to ensure that our clients receive their orders in the best possible condition. Closed cell foams are so widely used due to their extremely flexible characteristics. They are durable, resilient, lightweight and waterproof.
Cellular foam rubber made by KÖPP is the ideal material for sealing, insulating, isolating, damping and rattle prevention. That is why this cost-effective material is used successfully throughout industry. The material can be supplied in blocks, sheets or rolls. It can be punched, milled or customised to your requirements. It is also available in a self-adhesive a self-adhesive version. KOEPPcell® cellular rubber can be processed in many different ways.

Advantages of Closed Cell Foam
Closed cell foams are popular in a wide number of industries because they have a number of great characteristics. It produces minimal vibration and has high energy absorption properties. It resists water, oil, ozone and detrimental weather conditions. It's an excellent sealant and will withstand a wide range of temperatures. It also has low levels of flammability and smoke release in the event of a fire. This makes the foam perfect for a wide range of industrial applications where other insulators can burn easily and become hazardous.
