Is PVC right for the part?
Where PVC works, and where another plastic may suit
General guidance on how PVC behaves. If your drawing specifies a PVC type or grade, we machine to it.
Where it works
- Chemicals
- Resists most acids, alkalis and salt solutions.
- Water
- Takes on almost no water, so it holds its size in wet service.
- Rigidity
- Stiffer than polyethylene or polypropylene, so flat parts stay flat.
- Flame
- Naturally self-extinguishing.
- Cost
- One of the lowest-cost rigid plastics.
Where another plastic may suit
| If the part needs | Often used instead |
|---|---|
| Higher heat PVC softens at fairly low temperatures. These keep their shape hotter. | |
| Solvents Ketones and chlorinated solvents attack PVC. These resist far more chemicals. | |
| Cold and impact Rigid PVC can crack from a sharp knock, more so in the cold. These stay tough. | |
| Wear and sliding PVC isn’t a bearing plastic. These are made for parts that slide and rub. |
Grades
PVC grades
PVC comes as Type I or Type II, in gray, white or clear, with CPVC as its higher-heat version. Name the grade on your drawing, or tell us how the part is used and we’ll suggest one.
| Grade | Typically used for |
|---|---|
| Type I | The standard grade, with the best chemical resistance. Gray is the most common color. |
| Type II | Higher impact strength, with slightly less chemical resistance. |
| Clear PVC | See-through covers and sight parts. |
| CPVC | The higher-heat version, for hotter water and chemical service. CPVC |

All plastics we machineCPVC is PVC with added chlorine. It handles hotter service. PVC is the usual choice at normal temperatures. We machine both, and if your drawing specifies one, we machine to it.
Type I is the standard grade and has the better chemical resistance. Type II is tougher against impact, with slightly less chemical resistance. If your drawing specifies a type, we machine to it.
Both resist a wide range of chemicals and suit wet service. PVC is stiffer and naturally self-extinguishing. Polypropylene is lighter and takes repeated flexing. We machine both, and we’ll suggest suitable plastics for the part.
Yes. We supply PVC sheet and rod, cut to size when you need it, through our material supply service.
