Plastic Properties of Polyvinylchloride (PVC)
PVC Parts
PVC is a great product for machining. Above shows two disks as well as a small section of machined piping.
Polyvinylchloride (PVC) has a linear structure similar to polyethylene but with a chlorine atom replacing a hydrogen atom on alternate carbon atoms. PVC itself is hard and rigid but the addition of phthalate esters as plasticizers makes it soft and pliable and ideal for gloves, photographic dishes and tubing. Polyvinylchloride is generally transparent with a bluish tint. It is attacked by many organic solvents but it has a very good resistance to oils and it has a low permeability to gases. In its rigid form PVC is available in sheets which can readily be welded to produce tanks, trays and troughs. It is not recommended for use above 70° Celsius although it can be taken to 80° for short periods.

Dynalab Corp's plastic fabrication shop fabricates many catalog and custom Polyvinylschloride products. If you can't find the product you require on our website please e-mail for a custom quote.

Don't see the answers to your PVC questions? It must be time to see what Mr. Plastic has to say. Mr. Plastic is a wealth of technical, practical and even some hysterical plastic advice. Please submit your request via e-mail, phone calls will not be accepted.
