Complete Guide on PPR (Polypropylene Random Copolymer): Types, Applications, Market Trends & More
1. What is PPR? | Full Form and Overview
PPR stands for Polypropylene Random Copolymer, a thermoplastic used primarily for hot and cold water piping systems. It is produced by the random polymerization of propylene with ethylene, which provides it with better impact strength, flexibility, and heat resistance compared to standard polypropylene.
2. Properties of PPR
-
High chemical and heat resistance
-
Long life expectancy (up to 50 years)
-
Corrosion and scale resistant
-
Excellent weldability
-
Non-toxic and hygienic for potable water use
-
High pressure and thermal endurance
3. Grades & Forms of PPR
| Grade | Applications |
|---|---|
| PPR Type 1 | General piping use |
| PPR Type 2 | Better pressure and heat resistance |
| PPR Type 3 (Random Copolymer) | Ideal for hot & cold water supply |
Available Forms:
-
Virgin Granules
-
Recycled PPR
-
Pipes & Fittings
-
Sheets & Rods
