Silicone foam hoses

Our silicone foam tubing (closed cell) is available for general purpose and in almost all of our special formulations. Our foam tubes can be manufactured with an inner diameter (ID) from 5 mm up to 70 mm and an outer diameter (OD) from 10 mm up to 100 mm.

Density (kg / m3) Min Max
250 6 mm 2 mm 80 mm 40 mm
400 6 mm 2 mm 60 mm 18 mm
530 6 mm 2 mm 40 mm 12 mm

Silicone foam rectangular profiles

Our silicone foam rectangular profiles can be manufactured from 2.5 mm thick and up to 100 mm wide. Applications include duct seals where the profile lies in a duct to provide a sealing surface. We are able to join the profiles to form rings or mitred corners.

Silicone foam profiles

Our silicone foam profiles are specifically tailored to our customers' requirements and can be manufactured in any of our general purpose and specialist grades. From simple 'P' profiles to more complex shapes, we can use our knowledge and experience to provide cost effective solutions to our customers through efficient design and manufacturing techniques.
