Testing standards and items of PVC

PVC is a homopolymer of vinyl chloride, which is called PVC for short. It is a thermoplastic resin polymerized by vinyl chloride under the action of initiator; It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. Common products: plates, pipes, doors and windows, wire skins, soles, toys, stationery, etc. What matters is the quality of PVC profile. The prerequisite for determining the quality of PVC profile is its formula composition, because poor formula can not produce high-quality profile. Therefore, it is necessary to design a reasonable formula for the manufacturers of profile. Next, microspectrum technology will provide you with some reference materials about PVC material test report and relevant standards, hoping to be helpful to our friends.

Testing range of PVC materials:

Impact property, tensile property, density, water absorption, wear resistance, apparent density, friction coefficient, tear property, thermal stability, moisture content, vibration test, salt spray test, aging test, surface resistivity, volume resistivity, breakdown voltage, dielectric constant, component analysis and other test items.

PVC material testing standard:

Apparent density g / cm30 5-0.8 elongation at break% 15-20

Tensile strength MPa 12-20 shore hardness D type 45-50

Bending strength MPa 12-18 water absorption% ≥ 1.5

Bending elastic strength MPa MPa 800-900 Vicat softening point ℃ 73-76
