Semi Open Cell EPDM Sponge Strip

At Advanced Seals & Gaskets Ltd, we supply a range of EPDM sponge strips, in various densities, grades and in various different products cut from the material.  One of the EPDM sponge grades we can offer is Semi-Open Cell EPDM sponge, sometimes also called Semi-closed cell sponge or semi-open cell foam.  This material is manufactured in block form, which we can split down into sheets or join together and then split to produce continuous lengths or rolls of materials in thicknesses starting at just 1.5mm which can be used to cut into strips. 

By following our customer's samples, drawings or given dimensions, we can produce made to measure Semi-Open Cell EPDM sponge strips using our bandsaws, strippers, log cutters and even presses depending upon the size and quantity of strips required.  In-house production allows us to closely oversee the whole production process to ensure that we consistently produce high quality, competitive prices strips. 

Our Semi-Open Cell EPDM sponge strips are cut from sheets or rolls split down to thicknesses starting at just 1.5mm thick, we can produce strips from 4mm in width and from a few millimetres long up to 50 meters in length (depending on thickness).  During the conversion process, we can laminate layers of Semi-Open Cell EPDM sponge material to produce greater depths or supply them plain, laminated with a choice of self-adhesive foils or even other materials.

Semi-Open Cell EPDM is an extremely soft and flexible grade of EPDM sponge rubber, still manufactured from the chemical components Ethylene Propylene Diene Monomer, but using a different manufacturing process to create the mixture of open and closed cells throughout the material. 

The cell structure of Semi-Open Cell EPDM is created in the manufacturing process by physically "bursting" the closed-cell structure in order to create a product that is softer and therefore easier to compress than the more traditional medium or firm grade EPDM sponge rubber, making it an ideal material for internal and external sealing applications where minimal compression is required for the strips to work effectively.  

Semi-Open Cell EPDM sponge strips are lengths of material often cut to a specific length or supplied as continuous rolls/coils to be cut as and when needed by the end-user.  Semi-Open Cell EPDM sponge strips are often purchased to be used in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities or for anti-vibration and acoustic insulations.
