Advantages and Disadvantages of PVC (Polyvinyl Chloride) Magnetic Disc Coupling
- Advantages:
- Lightweight and easy to shape
- Corrosion resistant
- Good electrical insulator
- Available in a wide range of colors and finishes
- Disadvantages:
- Not as strong as metals
- Can be susceptible to UV degradation
- Not suitable for high-temperature applications
- Can release harmful fumes when burned
Polyvinyl chloride (PVC) disc magnetic coupling
Our PVC disc type magnetic coupling is manufactured using rigid PVC, a versatile and widely-used thermoplastic polymer known for its durability and chemical resistance. PVC is the world's third-most produced synthetic plastic, and is commonly used in construction, packaging, and various industrial applications.
