Polyethylene in comprised of only Hydrogen and Carbon atoms, so it can be written as [CH2-CH2]n whilst instead of two hydrogens and 1 carbon making a continuous chain, PVC has a Chlorine, so it is
[CH2-CHCl]
Unplastcized polyvinyl chloride
uPVC, or unplasticized polyvinyl chloride, is already a form of PVC (polyvinyl chloride) that lacks plasticizers, making it rigid and inflexible. To convert uPVC into a more flexible PVC, plasticizers are added during the manufacturing process. This addition alters the material's properties, allowing it to be used in applications requiring flexibility and softness, such as in flexible tubing or vinyl flooring. The transformation primarily involves blending uPVC with specific chemical additives rather than a chemical conversion.
The difference between schedule 40 and 80 pvc is the wall thickness and schedule 80 is thicker then schedule 40 so the higher the schedule number the thicker the wall of the pipe thus can hold more pressure.
PVC is the acronym for polyvinylchloride. It is a thermoplastic polymer. It is one of the most commonly used thermoplastic polymers, and is one of the highest revenue-generating products in the chemical industry. It is used to make electric wires, polyvinylchloride (PVC) pipes and unplasticised polyvinylchloride (uPVC) pipes. The most common use of polyvinylchloride (PVC) is to make pipes. The pipes are most commonly used for the purposes of drainage and for protecting or containing the cables in buildings. Unplasticised polyvinylchloride (abbreviated as uPVC) is a low maintenance material. It is used in the construction industry. It is available in a variety of colours and finishes. The photo-effect wood finish of unplasticised polyvinylchloride is used in window frames and window sills as a substitute for painted wood. It is also used as a replacement for older windows which have been installed with a single glazing or while installing double glazing in a new building.
the difference is that in pvc h-c is replaced with c-cl. c-cl is less oxidisible by air while h-cl is oxidisable hence flamable while cl-c doesn't
The main difference between PVC (polyvinyl chloride) and uPVC (unplasticized polyvinyl chloride) pipes is the composition of the material. PVC pipes contain added plasticizers to make them more flexible, whereas uPVC pipes are rigid and do not contain plasticizers, making them better suited for pressure applications such as water supply lines. uPVC pipes are also more resistant to chemical corrosion and are typically used in plumbing and drainage systems.
SWR pipes are used for drainage systems and are made of a special type of PVC material that is resistant to chemicals and high temperatures. uPVC pipes, on the other hand, are used for water supply systems and are made of unplasticized PVC material that is strong and durable. The main difference between the two is their intended use and the type of material they are made of.
As far as I know, uPVC (unplasticized polyvinyl chloride) sewer pipe is still a very costly specialty item, and currently only used for gutters and the like. PVC and uPVC are essentially the same thing expect for one difference. uPVC is not plasticized. The plasticizers in PVC are the main thing by which it causes enviromental damge. Mechanically speaking though, it would make no difference. PVC is very common and works quite well in all its applications. If you want to save major cash though, use ABS.
Unplastcized polyvinyl chloride
The only difference between gray and white PVC piping is in the color. They're both PVC.
The plastic Poly Vinyl Chloride is commonly abbreviated to PVC. UPVC is Unplasticised Poly Vinyl Chloride and is a rigid form of PVC often used in the building industry as a low-maintenance material.

UPVC is unplasticised, rigid, PVC. PVC resin must be compounded with various additives to make it a useful product. Heat stabilisers, pigments, lubricants,process aids, impact modifiers and fillers are all added to the raw PVC resin to allow it to be processed into a durable product. If a liquid plasticiser is added to the PVC compound the finished PVC product becomes flexible, ie, no longer rigid.

uPVC or un-plasticized polyvinyl chloride is manufactured the same way as all PVC resin is. The process takes ethylene and reacts it with chlorine to form ethylene dichloride (EDC). It is then reacted to form vinyl chloride monomer (VCM), which in turn is reacted to form Polyvinyl Chloride. (PVC).
