TempRite® Engineered Materials offers CPVC resins and compounds covering a wide spectrum of performance attributes. This allows more manufacturers worldwide to utilize CPVC’s inherent benefits in their product designs.
A range of resins having different molecular weights and chlorine contents, as well as a variety of compounds tailored to different part manufacturing processes make CPVC the smart way to get high performance products, profiles, parts and fittings.
Properties of TempRite CPVC
CPVC resin is created through chlorination of the PVC molecular chain. Chlorine atoms surround the chain, stiffening the carbon backbone and driving the softening temperature higher. CPVC resin, when specified for material compounds provide a number of advantages:
- Heat resistance
- Fire and smoke characteristics
- UV resistance
- Resistance to corrosion
- Environmental benefits
TempRite CPVC resins can be compounded with a variety of additives that can tailor each of these characteristics of the finished product:
- Tensile strength
- Heat distortion temperature
- Long term creep performance
- Flame & smoke performance
- Impact strength
Manufacturing with TempRite CPVC
TempRite CPVC is suitable for a variety of parts manufacturing processes, including extrusion, injection molding, thermoforming, and compression molding. CPVC parts can be fabricated into assemblies by a variety of options including solvent welding, hot plate welding, rod welding, and extrusion welding. CPVC provides a number of benefits over other materials in parts manufacturing.
✔ Mold shrinkage/appearance - Because it is a rigid amorphous thermoplastic, CPVC generally has much less mold shrinkage than many other materials and produces parts with a smoother glossier surface.
✔ Thermoforming - CPVC gives manufacturers the ability to extrude sheets and re-mold them into other shapes.
✔ Vacuum forming - CPVC can be extruded into sheets and vacuumed down into different molds, offering a fast and flexible solution to many applications, such as signage, trays and shells.
✔ Foaming for lightweight applications - Amorphous materials such as CPVC can be extruded as foamed material, for a variety of lightweight applications. Polystyrene-like packaging can be manufactured and used with the inherent fire repellent properties of CPVC.
✔ Weldability - CPVC can be welded with solvents or with a variety of common welding techniques including hot-plate welding, rod welding, and extrusion welding.
✔ Recycling - CPVC can be reheated and remoulded after initial processing, minimising wastage in the manufacturing process.
While manufacturing with CPVC is similar to PVC, it is not the same. To learn more about how to use TempRite CPVC in your processes, contact us to talk to a TempRite Engineered Materials representative.
