Flame Retardant PVC Compound
- Compared to ordinary PVC insulation, flame-retardant PVC insulation reduces the rate at which flames spread along cables.
- It helps cables pass vertical flame retardancy tests or bundle flame retardancy tests.
- Depending on the formulation, it can be used for cable insulation and sheathing, maintaining good mechanical and electrical properties.

Key Advantages of ZMS Flame Retardant PVC Compounds
1. Reliable Flame Retardant Properties
Designed to help cables pass typical flame retardant tests such as IEC 60332-1 and similar standards, ensuring consistent flame retardant performance between batches. Commonly used for insulation and sheath materials.
2. Stable Cable Extrusion Production Lines
FR PVC material exhibits good melt flow and thermal stability during the injection molding process. The extruded cable sheath layer has a smooth surface and uniform diameter, making it suitable for high-speed extrusion and continuous production.
3. Balanced Mechanical & Electrical Properties
Maintains the required tensile strength and elongation, exhibits good flexibility and bending properties, and provides reliable electrical insulation performance throughout processing.
4. Environmentally Friendly
Utilizes a lead-free calcium-zinc stabilizer system and offers formulations compliant with RoHS and REACH standards. Phthalate-free or low-toxicity plasticizers can be selected based on market demand.
5. Customizable Formulations
Hardness, color, flame retardancy rating, and smoke performance are all adjustable. UV resistance, cold resistance, or oil resistance can be added to meet specific application requirements. Suitable for different operating temperature ratings (70°C/90°C) and various cable standards.
