Adhesive Backed Gaskets
Stockwell Elastomerics has a proven expertise in manufacturing adhesive backed rubber gaskets, integrating premium adhesives with engineered gasketing materials. Engineers and designers can select from a menu of adhesives and gasket materials to create a custom combination the best suits their application. Adhesive backed gaskets, sometimes called peel and stick gaskets, feature ease of installation, gasket positioning, dimensional stability, and can be made as kiss-cut gaskets supplied on a roll.
Ease of installation – A peel and stick gasket allows assemblers to install a gasket or pad quickly and hold it in place during product assembly and shipping.
Gasket positioning – Adhesive backing on door gaskets holds the gasket in position when the door is opened and closed. This feature also applies to other enclosures such as clamshell gaskets and battery compartment gaskets. Without a pressure sensitive adhesive (PSA) backing, the gasket can move when the lid or mating surfaces are compressed. The motion of the mating faces can move or twist the gasket causing an ingress path.
Kiss-cutting – Adhesive backings allow for gaskets to be kiss-cut. This is often preferred by manufacturing engineers since parts are presented to the assembly operators on rolls. Parts can be removed from the adhesive liner easily, compared to individual cut-though parts that require time consuming adhesive liner removal.
Bolt hole position – Double-coat adhesive backing or film supported adhesive provides gaskets having a series of bolt holes dimensional stability. The thin PET film layer embedded in the adhesive limits the gasket from stretching in the X and Y dimensions during removal of the release liner. Without the film support, large soft gaskets cut from high elongation materials may stretch during installation, causing the bolt holes not to line up with the matching surface.

Material and Adhesive – Combinations
Stockwell Elastomerics applies adhesives at the time of running an order, allowing for a wide range of design flexibility. Most adhesive and materials offered by Stockwell Elastomerics can be combined; this flexible manufacturing helps engineers specify the best material and adhesive for their application. Custom gaskets, particularly custom adhesive backed gaskets, are Stockwell Elastomerics’ core competence.
Secondary Release Liner for Easy Peel Foam Adhesive Backed Gaskets Demo
The video above illustrates a secondary, twelve point (12pt) liner vs. the inherent liner (very thin paper) that is supplied with the adhesive. Very often the inherently liner is very difficult to remove from thick, soft foam products. Stockwell Elastomerics’ 12pt can be used to greatly improve handling and liner removal during installation.
