Abstract:
A composition includes thermoplastic polyurethane (TPU) and methyl methacrylate-acrylonitrile-butadiene-styrene (MABS) graft copolymer. The TPU is present in an amount of greater than 40 parts by weight, and the MABS graft copolymer is present in an amount of from 1 to 50 parts by weight, both based on the total weight of the composition. The composition has a light transmission value of at least 40%, as measured in accordance with ASTM D-1003, and a coefficient of friction of less than 1.5. The composition including the TPU and the MABS graft copolymer in the above weight ranges has good transparency, elongation, tensile strength, tear strength, elasticity, chemical resistance, and abrasion resistance that are all associated with the TPU. The presence of the MABS graft copolymer in the composition lowers the coefficient of friction of the TPU and while still substantially maintaining the light transmission value of the TPU, making the composition useful in many applications, especially in the pipeline repair industry.
