1. PPR Piping Systems

We are have carefully blended and formulated our own PP-R resins (polypropylene-random) which guarantee that we are only using the highest quality of PP-R granules in our piping systems. A random copolymer grade of PP-R was specially developed for engineering applications with certain stringent requirements.

The random combination of short and long hydrocarbon chains gives rigidity and flexibility resulting higher resistance to external damage for superior physical properties. Compression strength, elasticity, anti-corrosive and heat resistance properties are the factors which make it suitable for potable hot and cold water applications.

RAKtherm PPR systems are extensively used in food and medical industries owing to its harmless and safe properties. Proven to be non-toxic and stable chemically even at elevated temperatures.

RAKtherm PPR piping systems is manufactured in conformance to DIN 8077/8078 German standard.

PPR is the Perfect Solution

In accordance with its areas of application, RAKtherm piping systems is designed for continuous temperatures of 0°C to 90°C, and short-term peak temperatures of up to 100°C with a service life of 50 years. Therefore, RAKtherm is the perfect solution for all types of chilled and heating water networks.

RAKtherm PPR pipes is also very light in weight which is a big advantage for installation and handling and its fusion welding guarantees perfect seal therefore prevents leakage. Chemical components of PPR plastic pipe materials prevent from any bacterial growth which makes RAKtherm highly hygienic and non-toxic.

RAKtherm, a Healthy Choice and Environment Friendly

We believe that health is wealth; we never compromise the safety of our products. At RAKtherm, we produce products that are safe and harmless both for human’s health and environment.

PP-R is a material with excellent chemical resistance which does not react to most chemicals, with non-corrosive properties, proven to be physiologically and microbiologically harmless making it suitable for hot and cold water applications. All materials used in piping systems are 100% recyclable which can be used again in other plastic products, no nickels and chrome which can be found in metal fittings.

3. PEX Piping Systems

PEX refers to cross linked polyethylene (PE-X). It is a polymeric material formed by the chemical joining of individual polyethylene molecules in a process called “crosslinking”, because cross linking alters the performance of the original polyethylene polymer improving its’ properties. The primary reason for cross linking the polyethylene (PE) is to increase the physical properties and materials’ elevated temperature performance under load.

This results in a structure that does not soften when high temperature is applied, thus raising the thermal stability of the material under load, which greatly increases the environmental stress crack resistance, resistance to slow crack growth due to deterioration of the material under continuous temperature use, chemical resistance, toughness and abrasion resistance.
