Questions & Answers
PVC curtains are available in the following types: opaque colored, ribbed, welded bronze and red, frost-resistant, antistatic, frost-resistant ribbed, super frost-resistant, standard transparent.
ISO 868 - Plastics and Hard Rubber. Determination of Shore Hardness. This standard defines a method for measuring the hardness of soft PVC plastics used to create strip curtains. It establishes a standard procedure for determining the hardness of plastics and hard rubber by measuring the resistance of a surface to penetration by an indenter under a specified load.
ISO 527 is a standard specifying test methods for evaluating the tensile mechanical properties of plastics. It defines procedures for measuring elastic modulus, tensile strength, and elongation at break, ensuring the comparability of results in research and industry.
ISO 1183-1 specifies methods for measuring the density of non-cellular plastics. This standard is used to compare different plastics, assess material homogeneity, and control quality. It includes methods for determining the density of non-cellular plastics in the liquid or solid state. It applies to filled composites, thermoplastics, resins, and thermosetting materials.
