The World of expanSil™

Silicone Engineering’s signature silicone sponge material, expanSil™, has become a vital component in a wide range of global markets - such as Aerospace, Rail and Mass Transit, Lighting and Construction.

Designed and developed specifically for the manufacture of extruded silicone sponge products, the expanSil™ range offers incredible resilience and versatility for industries where adverse temperatures are an issue and where sealing is of utmost importance.

Available in General Purpose (GP) and a number of specialist grades, expanSil™ can also be used where there are uneven sealing surfaces requiring a supple material.

The popular material is manufactured in various different ways from tubing and cords to profiles and sections, making it ideal for hundreds of different applications.

Specialist expanSil™ grades include high temperature (expanSil™THT), flame retardant (expanSil™FR), UL94V0 (expanSil™UL) and low smoke and toxicity (expanSil™LCH). These materials are used where more demanding applications or environments are required and when regulations are priority.

Perfect for industries such as Mass Transit and Aerospace, expanSil™ specialist grades are continuously developed, refined and improved to allow the customer complete assurance that the expanSil™ range is of the highest quality and tested to international specifications.

This has created an impressive range of silicone formulations that comply with industry standards and meet ever-changing customer needs.

expanSil™ can also be produced with pressure sensitive adhesive (PSA) where force is applied in a certain application.

Owing to its continuous production process, Silicone Engineering can provide extended expanSil™ coil lengths, significantly reducing set-up and changeover times to increase a company’s operational efficiency and competitive advantage.

Available in several densities ranging from 200 kg/mᶟ (soft) up to 530 kg/mᶟ(firm) and in a range of standard colours white, red and grey.
