Polypropylene is a thermoplastic and partially crystalline resin belonging to the family of polyolefins. PP is obtained through the polymerization of propylene (C3H6) with the aid of catalysts. For use in piping systems, the latest-generation Polypropylene Homopolymer
variant, or PP-H, offers excellent performance at working temperatures of up to 100° C and a high resistance to chemicals due to the excellent physical and thermal characteristics of the
resin.The PP-H line in latest-generation Polypropylene Homopolymer consists of a comprehensive range of pipes, fittings and valves for use in the construction of process and service lines for conveying pressurised industrial fluids and for maximum operating temperatures of up to 100° C. The entire line is made of Polypropylene Homopolymer resins MRS 100 (PP-H 100) according to the classification DIN 8077-8078, DIN 16962 and
approved by DIBt - Deutsches Institut für Bautechnik for use in industrial processes.

The main properties of the latest-generation Homopolymer resins are:

High chemical resistance:

In addition to ensuring excellent chemical resistance, especially against halogens and alkaline solutions, the use of PP-H resins with special additives also ensures excellent mechanical properties when conveying detergents and similar chemicals. PP-H pipe systems are also fully compatible with the transport of drinking, unconditioned, demineralised and spa water for therapeutic and kinotherapeutic uses.

Excellent thermal stability:

Particularly in the intermediate temperature range between 10° C and 80°
C typical of industrial applications, PP-H ensures excellent mechanical
strength and impact resistance with high safety factors.

Resistance to ageing:

PP-H resins have a high circumferential breaking strength (Minimum
Required Strength MRS ≥ 10.0 MPa at 20°C) and allow long installation lifetimes without showing any signs of significant physical-mechanical deterioration.
