Materials Guide
Rigid PVC
Rigid PVC is a strong, durable thermoplastic widely recognized for its structural integrity and weatherability. It’s commonly chosen for applications that require long-term outdoor performance and flame resistance.
What is Rigid PVC?
Rigid PVC is a non-plasticized version of polyvinyl chloride, meaning no plasticizers are added to soften the material. This gives it superior strength, dimensional stability, and resistance to impact, chemicals, and environmental stress.
Common Applications
Rigid PVC is used extensively in construction and industrial products, including:
- Window and door profiles
- Pipes and fittings
- Siding and trim
- Outdoor decking and fencing components
- Electrical conduit and housings
Fun Fact: Rigid PVC's durability has made it one of the most common materials in building construction - more than 50% of PVC production worldwide goes to pipes and building products.
Important Considerations
Benefits
- High Strength
- Excellent flame resistance (self-extinguishing)
- Strong weatherability and UV stability with proper additives
- Long service life in outdoor environments
- Cost-effective compared to many engineering plastics
Limitations
- Limited flexibility (can be brittle under impact at low temps)
- Lower heat resistance than CPVC or polycarbonate
- Requires stabilizers for extended UV protection
- Heavier than some alternative plastics
