What Is PVC Plastic?
Machining of PVC
PVC (Polyvinyl Chloride) is a durable thermoplastic material widely used in industrial, chemical, and electrical applications. It offers excellent resistance to acids, alkalis, salts, and many corrosive chemicals while maintaining good mechanical strength and dimensional stability.
PVC is available in several grades, including rigid PVC, high-impact PVC, and clear PVC, allowing it to meet the requirements of a wide range of engineering applications.
Please contact our sales and technical teams to learn about how we can provide high-quality machining PVC Engineering plastic services at a fair and competitive price.

PVC vs CPVC: Which Vinyl Plastic Should You Choose for Your Project?
PVC and CPVC (chlorinated PVC) are both versatile vinyl-based plastics, but CPVC offers higher temperature resistance while PVC provides better impact strength at a lower cost.
| Property | PVC (Rigid) | CPVC (Chlorinated PVC) |
|---|---|---|
| Max Service Temperature | 60-80°C | 90-105°C |
| Tensile Strength | 45-55 MPa | 50-60 MPa |
| Impact Resistance | Good | Moderate |
| Chemical Resistance | Excellent (acids, alkalis) | Excellent (broader range) |
| Flame Rating | UL94 V-0 (self-extinguishing) | UL94 V-0 (self-extinguishing) |
| Density | 1.38-1.41 g/cm³ | 1.49-1.58 g/cm³ |
| Moisture Absorption | Very Low | Very Low |
| Electrical Insulation | Excellent | Excellent |
| Machinability | Excellent | Good |
| Relative Cost | $ | $$ |
| Best For | Chemical processing, electrical enclosures, piping, construction, industrial components up to 80°C | Hot chemical processing, high-temperature piping, industrial applications up to 105°C |
Choose PVC if you need a cost-effective, impact-resistant vinyl plastic for chemical processing and industrial applications operating below 80°C. Choose CPVC if your application requires higher continuous service temperature (up to 105°C) or broader chemical resistance for hot chemical environments.
