Applications	-	Specially designed with lowest modulus and highest elongation for the most difficult asymmetrical glass clad and plastic laminates	Specially designed to have mid to low modulus properties, excellent low temperature impact resistance and tensile strength which is ideal for large span curved transparencies.	Specially designed for the lamination of optical transparencies using dissimilar products such as glass, polycarbonate, acrylic, and CAB	Specially designed for the lamination of glass to glass laminates with exposed edges. It is a very tough, high tear and high tensile polymer that will impart good impact resistance.

Paint Protection Film

Stevens Urethane offers SS-3119, a caprolactone-based Aliphatic TPU, with excellent abrasion resistance and contains a UV package that enhances outdoor weatherability. The material comes on a PET interlayer which gives the material a high-gloss finish. The following is its general properties.
