The PP-R pipe is also called type three polypropylene pipe and random copolymerized polypropylene. It is made of random copolymerized polypropylene, which can be extruded into tubes and can be molded into tubes. Ethylene is the most commonly used monomer, which causes changes in physical properties of polypropylene.and it has the characteristics of good toughness, high strength, excellent processability, high creep resistance at high temperature, and the unique high transparency of atactic polypropylene.
PPR (polypropylene random) have the characteristics of good toughness, high strength, excellent processing performance, high temperature creep .
1, )the building's hot and cold water system, including central heating system;
2. )Building heating systems, including floors, panels and radiant heating systems;
3. )Pure water supply system for direct drinking;
4 .)entral (centralized) air conditioning system;
1.)Non-toxic and hygienic.
2.)Thermal insulation and energy saving
3.)Better heat resistance
5.)Easy installation and reliable connection
6.)High temperature resistance, high pressure resistance, excellent corrosion resistance
7.)Pretty good flame retardancy
(1) High Temperature Resistance: the maximum sustained working temperature is up to 70 Degrees Celsius,
the maximum transient temperature is up to 95 Degrees Celsius. (2) Heat Preservation: low thermal conductivity which is only 1/1500 of brass pipe, and 1/250 of steel pipe.
Non-toxic: no heavy metal additives would not be covered with dirty or contaminated by bacterium. (3) Corrosion Resistant: resist chemical matters or electron chemical corrosion. (4) Lower Installation Costs: light weight and ease of installation can reduce installation costs by as much as 50% over metal piping system. (5) Higher Flow Capacity: smooth interior walls result in lower pressure loss and higher volume than metal pipes. (6) Long Life: more than 50 years under normal conditions. (7) Recycled and Environment-friendly.
