-84.48%Rigid PVC (polyvinyl chloride) is a hard plastic that resists acids, bases and many chemicals, insulates electricity and puts itself out once the flame is removed. It weighs 1.35–1.45 g/cm³, barely absorbs moisture and works up to about 60 °C. That is why it is used for insulating supports, flanges, lids, plates and parts for tanks, piping and electrical enclosures. At PREMSA we CNC mill and turn it from your file, starting at a single part with an instant price.
PVC properties: mechanical, physical, thermal, electrical and chemical data to choose the material for your machined part.

What people ask most about PVC parts: what it is, uses, machining, chemicals, temperature, strength, insulation, flame, bonding, threads, weight, price and tolerances.
Rigid PVC is chosen for parts that have to insulate electricity or work with chemicals and water: insulating supports, flanges, lids, plates and parts for tanks, piping and electrical enclosures.
At PREMSA Industries we machine PVC with CNC milling and turning from your file, from a prototype to production.
Rigid PVC is chosen when the part has to insulate, resist chemicals and hold its shape.
If your drawing doesn’t specify tolerances, we machine to ISO 2768-m (medium). On dimensions you call out —holes, slots, contours and fits— we can hold ±0.1 mm (±0.004 in), and critical dimensions are checked in inspection. Rigid PVC is stable, so it holds its dimensions well after machining.
PVC is machined with CNC milling, CNC turning, drilling and tapping. It is cut with sharp tooling, steady feed and good chip evacuation so it doesn’t heat up and soften. Threads are tapped into the material and, if they will be tightened and loosened often, an insert is a better choice.
Because it insulates electricity and resists chemicals, PVC is used in many parts made with CNC machining.
PVC is usually the right choice when the part has to insulate electricity or work with chemicals at room temperature.
