Developed in 1930 in Germany, the UPVC (unplasticized polyvinyl chloride) is obtained by the process of polymerization vinyl chloride (a gaseous monomer). An highly
reliable resin with high performance of thermal stability, chemical and mechanical resistance up to 60° C, is obtained by the presence of chlorine in the molecule of PVC.
The different formulations obtained by the addition of suitable additives and stabilizers, make PVC the more versatile of the plastic materials, having several possibilities to be used in many applications of the fluids in pressure

The UPVC represents one of the most economic solutions within the range of thermoplastic and metal materials. The system overcomes problems which can be encountered in the service lines of the industrial fields for the conveyance of corrosive chemical fluids and also in the distribution- treatment of general water. The main reasons for the preference of this system are attributed to the following characteristics of the resin:
The UPVC is basically inert to most inorganic bases, acids, saline solutions and paraffinical/aliphatic hydrocarbons. It is not recommended for use with polar organic solvent, including chlorinated and aromatic types. The unique molecular structure grants a low coefficient of thermal conductivity (λ = 0,15 W/m °C according to ASTM C177). It virtually eliminates condensation and offers superior heat retention reducing heat loss through piping walls. Low permeability to oxygen and reduced water absorption (0,1% at 23°C according to ASTM D 570).Good resistance to ageing, thanks to the chemical and physical properties of the UPVC resin.

All components are suitable for conveying potable water, beverages and food. The basic resins employed are all NSF approved.
The material has excellent mechanical characteristics and good impact strength. These properties make the UPVC suitable for high service pressure (up to 4 – 6 – 10 – 16 bar at 20°C).
The UPVC compounds, presents important characteristics of fire performance, in fact the flash ignition temperature is 399° C and it persists only in extreme conditions, e.g. if the Oxygen concentration is two times higher than the atmospheric one, or only in presence of external flame source. Flash ignition temperature: 399° C
Limiting Oxygen Index: 45%
Class UL 94 rating: V0


The UPVC range is a complete range of fittings for solvent welding, threaded connection for use in the construction of process and service lines to convey industrial fluids at maximum operating temperatures of 60°C.The entire range is produced using UPVC resins compliant with the standards EN ISO 1452 and ISO 4422 and in observance of the requirements of DIN 8063 and EN ISO 15493 for the use of plastic pipes in industrial processes. FIP UPVC fittings are suitable for naval applications and classified according to Boureau Veritas.

Main properties and characteristics:
Good chemical resistance:
UPVC resins guarantee excellent chemical resistance with regard to most acids and alkalis, aliphatic hydrocarbons and saline solutions. UPVC resins are also totally compatible for the handling of food grade fluids, treated and untreated drinking water, as well as demineralised water according to current national and international standards.

Good thermal stability:
mostly in the intermediate temperature range between 20°C and 50°C, UPVC finds its ideal application in industrial and water supplies, assuring optimal performance in terms of mechanical resistance, good rigidity, low coefficients of thermal expansion and optimal safety factors in service.

UPVC resins feature is an high value in the material strength (Minimum Required Strength MRS > 25.0 Mpa at 20°C) and an extremely extended lifetime.

The possibility to choice between different jointing systems make low costs in the operations of installation.
