Chemical & Heat-Resistant
Custom Plastic Parts
PlasticCNCPro provides precision CPVC CNC machining for custom components that demand heat and chemical resistance, electrical insulation, and dependable dimensional control. From prototypes to repeat low-volume production, we machine CPVC and other engineering plastics with an engineering-first approach.
Engineered for Demanding Environments
Chlorinated polyvinyl chloride (CPVC) delivers a unique combination of properties that make it ideal for hot/corrosive fluid handling, electrical insulation, and structural applications where standard PVC falls short.
Elevated Temperature Performance
Handles hot water and heated chemical service well beyond the limits of standard PVC, making it suitable for continuous-use applications up to 93 °C (200 °F).
Chemical Resistance
Excellent resistance to acids, bases, salts, and many aqueous solutions. Intrinsically flame-retardant and self-extinguishing (many grades meet UL 94 V-0).
Electrical Insulation & Stability
Good dielectric properties, low moisture absorption, and dimensional stability for structural and fluid-handling parts where metal corrosion or weight is a concern.
Flame Retardant
Self-extinguishing behavior reduces fire risk in electrical and industrial equipment. Many CPVC grades carry UL 94 V-0 certification for critical applications.
Dimensional Rigidity
Excellent stiffness and creep resistance compared to many other thermoplastics, with low moisture absorption ensuring stable dimensions in humid or wet environments.
Application Versatility
Proven in chemical-processing equipment, water treatment, electrical/insulation, hot fluid handling, and structural components where metal corrosion or weight is a concern.
Material Grades We Machine
We routinely machine a wide range of CPVC stock forms and specialty grades to meet your design requirements.
