Compression Seal Profile Constructs

Compression seals, gaskets, bumpers, and tubing can be manufactured a number of different ways. At Pawling EP, we specialize in extruded rubber and plastic profiles, although we can mold these products too if required. The following provides a general overview of the constructs you may be familiar with, but not understand completely.

Dense Extruded Rubber ProfilesDense

The majority of our extruded parts are manufactured using dense materials. Dense profiles are resilient and extrudable whereas some other constructs can only be molded. We offer a wide range of dense materials to select from, including TPV, EPDM, Neoprene, Silicone, and FKM.

Co-Extruded Rubber ProfilesCo-Extruded

Some applications require two types of materials (usually having different durometers) to be joined together to form one part. A typical application involves a rigid component that acts as a retainer and a flexible component to act as a seal or bumper. This is most common with plastic materials.

Sponge Rubber ProfileSponge

Sponge extrusions provide a soft, supple seal while optimizing material usage. Sponge profiles should not be used where compression set is important, because the part will eventually take a permanent set. We do not have expertise with sponge extrusions and can recommend other suppliers if this is what you need.

Fabric Reinforced Rubber ProfileFabric Reinforced

Fabric reinforcement serves many purposes.  Embedded fabric can strengthen a part's tensile strength which will allow it to withstand harsh applications.  It also can be used on a part's surface to reduce coefficient of friction. At Pawling EP, fabric reinforcement can only be applied by molding the part.

Multi-Laminate Rubber ProfileMulti Laminate

Multi-laminate designs are used in extreme applications, like airplane hatch seals.  Aerospace applications use a multi-laminate construct of fabric, silicone, and polyester. The outer fabric reduces the part's co-efficient of friction and the rigid polyester molded insert ensures that the part does not pull out of its retainer.
