Worthen Performance Films (WPF) produces high-performance thermoplastic films which are used in a variety of physically and chemically demanding applications.
What separates WPF from other thermoplastic film suppliers is that we can draw from the talents and ideas of other Worthen business units. WPF can apply unique Worthen adhesives and coatings to our thermoplastic films and/or compound a resin specifically for your application. Our co-extrusion capabilities allow us to manufacture single or multi-layer thermoplastic films in a wide variety of thicknesses, colors, and finishes.
Whether you are looking for an adhesive-coated film, cast film, or cast-on-carrier film, WPF would like the opportunity to be your thermoplastic film supplier.

Urethanes were the first major elastomer that was capable of being processed by thermoplastic methods. Urethanes have outstanding abrasion resistance. The low temperature flexibility is good. Oil resistance is excellent. Additives can improve dimensional stability and heat resistance, increase flame retardancy and weatherability. Urethanes are a reaction product of a di isocyanate and long and short polyether, polyester or caprolactone glycols. Polyether types have better hydrolytic stability and low temperature flexibility than the polyester types. TPU's come in a wide range of hardness grades.
Ethylene vinyl acetate is inherently flexible, tough and clear. They demonstrate excellent resistance to ozone and environmental stress cracking. EVA's range commercially from 6 to 40% of vinyl acetate. EVA can be extruded as is or as an additive to improve performance properties of other elastomers. EVA do not have plasticizers to migrate which is an advantage over PVC.
Thermoplastic rubber elastomer/Thermoplastic vulcanizate. TPR's provide properties tailored to meet tack, stiffness and cohesive strength of the desired product needs. TPR's contain both hard and soft segment. TPR's are light in weight, colorable with excellent abrasion resistance. TPR's have good low temperature flexibility and electrical properties. TPV's are compounds containing a fully crosslinked rubber in a continuous thermoplastic matrix of plastic. TPV's have excellent electrical properties and impact strength with high flex fatigue resistance and excellent weathering properties. Both TPR and TPV are suited to a wide formulating spectrum.
An ionomer is a polymer which has ethylene as the major component but contains both covalent and ionic bonds. Common ionomer types contain metal salts of either sodium, zinc or lithium. Ionomers have a unique combination of higher stiffness and excellent sealant properties. Ionomers are clear materials, easily compounded with other additives. Ionomers provide excellent electrical properties.
Olefins cover a wide range of materials including polyethylene and polypropylene. Selection of the proper grade will depend on the desired properties of the end product. Olefins are widely used in extrusion applications where chemical resistance, tear strength, toughness and tensile strength is required.
