Softener. A substance added to materials to impart flexibility, workablilty and elongation.

Loss of plasticizer from an elastomeric compound that is absorbed into the adhesive. The result is a softening of the adhesive to the point of adhesion failure.

A strong film having good resistance to moisture, solvents, oils and many other chemicals. It is usually transparent.

An extruded, tough stretchy film having limited temperature resistance but good moisture barrier properties. Good for low temperature applications.

A strong, tough engineering film which resists deformation or decomposition at temperatures in excess of 500 degrees F for many hours. As such, it provides a stable base for polyimide label stock for polyimide labels in barcode applications.

Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units, each a relatively light and simple molecule.

A polyolefin plastic similar in properties to polyethylene but with higher temperature capability and greater strength. A cousin of polyethylene, with generally similar properties, but stronger and having a higher temperature resistance.

A water-white thermoplastic produced by the polymerization of styrene. The electrical insulation properties of polystyrene are outstandingly good and the material is relatively unaffected by moisture.

Trade name for polyethylene available in films or as custom molded articles.
