Polypropylene Random Copolymers are thermoplastic resins produced through the polymerization of propylene, with butane and ethylene bonds injected in polymer chain. The tar provide a broad range of characteristics, and are used as an extensive variety of applications.
The thermoplastic resins most often used to make pipes for water and heating systems are:
All the above mentioned resins belong to the polyolephine family, a group of plastic materials obtained by polymerization of unsaturated hydrocarbons, which have one or more double links.
In a conventional polymer the molecular chains are irregularly placed; they have fairly good mobility, heat causes oscillation in these chains until they break, resulting in alteration of the material’s characteristics.
Two ways of preventing this problem have been tested.
Thus it is guaranteed that goods manufactured have high mechanical properties; it has been stabilized with appropriate anti-oxidants to postpone the combined effects of pressure and temperature for a very long time.
Property of Raw Material
KPT- PPR Plumbing Pipe system is made from Basel & Hyosung materials which are considered as one of the best PPR material all over the world, a PPR approved for the production of pipes and fittings according to DIN 8078 & DIN 16962 standards. PPR Raw material is a thermoplastic resin which is transformed into the final product by an ascent in temperature to plasticize the material to allow the pipe to be prepared through EXTRUSION, and the fittings by MOULDING. The raw material is supplied in granules precolored. Special heat resistance is one of the features of this material, lts physical and chemical properties are well suited to the transfer of potable water and in the heating sector. Depending on pressure it is possible to use KPT pipes for constant temperatures up to 70°C with service life of more than 50 years. Peak temperatures of 100°C arising from shot disruptions are not creating any problems.
