3. PPRC pipe features Leak-proof & airtight homogenous joints by fusion welding methods. Negligible head loss, Minimum Pressure loss & Higher Flow Rate due to smooth internal surface & homogenous joints. Inherited characteristic of high impact strength makes its suitable for industrial application at unskilled labor region. Wide Temperature range: -4 0 C to +95 0 C (suitable for both hot & cold). Very low thermal loss, as PPR-C is poor conductor of heat & condensation Trouble-free installation process & light in weight for transmit.

4. PPRC pipe features Exceptional corrosion & erosion resistance as PPRC is a polymer product, hence after installing PPRC just forget about corrosion problems & so it is a ideal product for various Chemical & other Fluid transmit application. High chemical resistance power even at high temperature. Low Thermal Conductivity makes it an ideal Piping system where one needs to Control & Maintain the Temperature. Indeed it has the lowest Thermal Conductivity compared to any other polymers. Anti-Fungal & Non-toxic product, free from the growth of any bacteria.

5. PPRC pipe features Long Service life, above 50 years over a wide temperature range. Highly economical as compared to G. I., C. I., M. S., PVC and also CPVC. PPR-C being an Eco-Friendly product does not catches fire straightforwardly, indeed in case of fire it doesn’t produce toxic gases. Superior Impact, Fracture Resistance & Minimum Crack Transmission

6. Polypropylene material information The raw material PP-R is grouped into three classes according to the resistance against heat, compression and chemical characteristics. Type-1 : PP-H – polypropylene homopolymer Type-2 : PP-B – polypropylene block polymer Type-3 : PP-R – polypropylene random co-polymer Raw material type-3 has higher performance and superior qualities with respect to raw materials type-1 and type-2 from the points of physical and chemical characteristics.

7. Homopolymers – General Purpose Grade that can be used in a variety of different applications. Block copolymers- Incorporating 5-15% ethylene, have much improved impact resistance extending to temperatures below -20oC. Their toughness can be further enhanced by the addition of impact modifiers, traditionally elastomers in a blending process. Random copolymers – incorporate co-monomer units arranged randomly along the polypropylene long chain molecule. Such polymers typically containing 1-7% ethylene are selected where a lower melting point, more flexibility and enhanced clarity are advantageous. Different PP grades are available dependent on the application and chosen processing method Polypropylene material information

8. About Polypropylene Polypropylene is an economical material that offers a combination of outstanding physical, chemical, mechanical, thermal and electrical properties not found in any other thermoplastic. Compared to low or high density polyethylene, it has a lower impact strength, but superior working temperature and tensile strength. Polypropylene possesses excellent resistance to organic solvents, degreasing agents and electrolytic attack. It has a lower impact strength, but it's working temperatures and tensile strength are superior to low or high density polyethylene. It is light in weight, resistant to staining, and has a low moisture absorption rate. This is a tough, heat-resistant, semi-rigid material, ideal for the transfer of hot liquids or gases. It is recommended for vacuum systems and where higher heats and pressures are encountered. It has excellent resistance to acids and alkalies, but poor aromatic, aliphatic and chlorinated solvent resistance.
