What is polypropylene made of?
Polypropylene, also known as Olefin, is a synthetic thermoplastic polymer derived from oil and natural gas production. Up until the late 1950's, the gas propylene was a waste product of oil and natural gas facilities. It was not until Italian scientist, Giulio Natta, polymerized the gas propylene and made a commercially feasible plastic polypropylene. Polypropylene is then extruded through a shower head like device known as a spinneret. The spinneret creates the shape and length of threads. After the threads cool, they are spun together in various color and size combinations to make yarns. The polypropylene yarns are then woven into fabric.
What is PPR pipe grade material?
PPR is the abbreviation of type three polypropylene, also called random copolymer polypropylene pipe. It adopts a heat welding method, has special welding and cutting tools and has high plasticity. The price is also very economical. With an external insulation layer, the insulation performance is better, and the pipe wall is also very smooth, excluding the joints of the inner and outer wires. Generally used in embedded walls or deep well-embedded pipes. PPR pipes are moderately priced, stable in performance, heat-resistant, heat-insulating, corrosion-resistant, smooth inner walls, no scaling, safe and reliable piping systems, impermeable, and have a service life of up to 50 years. However, the construction technology requirements are high, and special tools and professionals are required for construction to ensure the safety of the system. The pipe PPR-P00 has developed rapidly in a short period of time due to its excellent mechanical properties, molding processing properties, good chemical stability, heat resistance, and creep resistance, and is widely used in various types of buildings. Cold and hot water delivery system.
