Abstract: Flexible, conformable, pressure sensitive adhesive film material has a plastic film and a compatible pressure sensitive adhesive layer on at least a first surface of the plastic film. The plastic film is formulated of plastic film polymers and optional additives. The plastic film polymers include, at least, thermoplastic ethylene/styrene interpolymer in major part, and a temperature modifier polymer, which increases the thermal resistance of the plastic film. The pressure sensitive adhesive layer is compatible with the plastic film, such as acrylic-based adhesive and shear-coated rubber-based adhesive. The PSA film material can be harness tape for use in wire harness constructions and can provide advantageously low fogging and good recyclability, along with performance characteristics suitable to stringent harness tape and other end-use applications. In certain embodiments, a plastic barrier layer is coextruded with the plastic film, and a surface of the plastic film opposite the adhesive layer.

Abstract: Adhesives, particularly pressure sensitive adhesives, and adhesive tapes, e.g., harness tapes, that exhibit low-fogging characteristics. The adhesive is a cured composition of an elastomer and a cure system including a sulfur-containing and a zinc-based curing agent.
