What is Machined PVC
PVC (polyvinyl chloride) is a lightweight, rigid thermoplastic know for its excellent chemical resistance, good dimensional stability, and ease of machining. In most conditions, PVC can holds its shape and doesn’t chip easily. Machined PVC parts are commonly used in fluid handling systems, electrical insulation, and structural supports.
Machined PVC Grades We Work With
There are a few main types of PVC that we regularly machine, each suited to different requirements. Here are the most common types we work with:
- Standard Rigid PVC: This is the most common type which is strong, lightweight, and has excellent chemical resistance. We machine it often for fittings, spacers, and enclosures.
- CPVC (Chlorinated PVC): When higher temperature resistance is required, we use CPVC. It machines similarly to standard PVC but holds up better under heat, especially for fluid system components.
- High-Density PVC: This grade offers added stiffness and better dimensional stability. It’s useful when tight tolerances and rigidity are important.
Great — here’s the Machined PVC Properties section, presented in a clean, data-focused table. These values reflect typical properties of rigid PVC used in CNC machining:

| Maximum Operating Temperature | ~60–70°C |
| Water Absorption (24h) | <0.1% |
Key Benefits of PVC Machining
- PVC has good dimensional stability, it can holds its shape well during and after machining.
- PVC has excellent chemical resistance that resistant to acids, bases, and salts.
- It has low water absorption rate makes PVC won’t swell deform easily in humid or wet environments.
- With good corrosion and weather resitant, PVC is suitable for both indoor and outdoor use when exposure to the elements is a concern.
- PVC is relatively low cost makes it budget-friendly without compromising utility in many applications.
Limitations of PVC Machining
- PVC has lower heat resistance, as it softens at relativly low temperatures (~60–80°C), so it’s not suitable for high-heat environments.
- It lacks the toughness and impact resistance, so PVC is not ideal for high-strength applications.
- Machining at incorrect speeds can generate harmful chlorine-based gases, it can release fumes when overheated.
- At low temperatures, PVC can become more rigid and prone to cracking under stress.
