About Flexible PVC FAQ
What is the difference between rigid PVC and soft PVC?
The main difference lies in the amount of plasticizer used and the resulting performance variations:
Rigid PVC
Contains almost no plasticizer, is rigid and stiff, and has high dimensional stability.
Used for pipes, profiles, window frames, cable trays, cable conduits, panels, etc..
Good shape stability and high modulus, but poor flexibility and impact resistance at low temperatures.
Flexible PVC
Contains a higher plasticizer content, giving the material flexibility.
Soft, bendable, and elastic, suitable for cable insulation and sheathing, hoses, plugs, seals, and flexible profiles.
Further superior flexibility and bending performance, but slightly lower hardness and mechanical strength than rigid PVC.
How durable are your flexible PVC granules?
ZMS Material supplies flexible PVC granules designed for cable insulation, sheathing, and other industrial applications, with a long service life. Under normal operating conditions and with proper cable design, their service life can reach 10-20 years or even longer, depending on the installation environment and voltage level.
They maintain good flexibility and mechanical strength even under repeated bending and handling.
The optimized formulation offers excellent heat resistance, typically reaching 70-90°C, helping cables maintain performance over the long term.
For outdoor or more demanding environments, we can adjust the formulation ratio to further enhance durability according to customer needs.
Of course, actual service life also depends on cable construction, processing conditions, and installation environment, but our products meet or exceed the requirements of IEC/UL/GB flexible PVC cable material standards.
