Product catalog summary

General Properties
Density of PVC ranges from 1.15 to 1.48 g/cm³ at 23°C.

Thermal Properties
Cold flex temperature is between -10°C and -50°C. The service temperature ranges from a minimum of -30°C to a maximum of 50°C for continuous use and 70°C for intermittent use.

Mechanical Properties
Softness is measured by BSS number ranging from 20 to 120. Hardness is measured on the Shore A scale from 40 to 90. Tensile strength varies between 5 and 20 MPa, with elongation at break between 250% and 450%. The modulus at 100% extension is between 2 and 15 MPa.

Flammability Properties
The oxygen index is between 25 and 40. The flammability rating according to UL 94 is HB to V0.

Chemical Properties
PVC shows good resistance to weak acids and alkalis but poor resistance to strong acids, strong alkalis, organic solvents, oils, and greases. It has good resistance to UV exposure.
