Chrysler Bending Tester

  Brief Introduction Chrysler bending tester is designed for bending and folding manner by testing base fabric adhesion of the coating material, ie mechanical stability of the coating.  Design Basis Chrysler laboratory test method LP-463LB-9-01.  This test characterizes the degree of adhesion about the vinyl coated fabric and leather fabric coating material. Also it can be vinyl coated fabrics, leather, unsupported rupture, whitening, cracking, lamellar separation of vinyl and other soft furnishings and other materials Product Description： A tester simultaneously tests four samples, including three bend specimens and a folded specimen. When the bending jig sample is clamped at both ends, and taut, holding one end is fixed and the other end of the horizontal movement, the bending test.  The folded ends of the sample close clamped between two opposing plates, a 12lb load is applied in the folding area. If possible, close the flat to exert the appropriate pressure....
