Basic classification of PVC sheet
Basic classification of PVC sheet PVC has high hardness and mechanical properties. And increase with the increase of molecular weight, but decrease with the increase of temperature. Hard PVC has good mechanical properties, and its elastic modulus can reach 1500-3000MPa. The elasticity of soft PVC is 1.5-15 MPa. But the elongation at break is as high as 200%-450%. The friction of PVC is g
