Polygon   PP- R pipe system is made of Vestolen P9421 that is one of the best PP- R material over the world, the material is supplied in granules pre colored. Special heat resistance is only one of the features of this material, its physical and chemical properties are well suited to the transfer of potable water and in the heating field. Depending on pressure it is possible to use Polygon  PP- R pipe for constant temperatures up to 70°C with service life of more than 50 years. Peak temperatures of 100°C arising from short disruption are unproblematic. Before processing, the granule under goes specific tests in our laboratories to verify its suitability for use.


Application of PPR Pipe

As a key type of Construction Material, it is widely used in the following fields:

  1. Portable water supply in residential buildings, hospitals, hotels, shipbuilding etc;

Hydrostatic Pressure Performance

The Performance of Polygon  PP-R Pipe

Thanks to the antibacterial granules which is added to inner layer of the pipes, it makes the pipe antibacterial, hygiene and clean.

For annealed Coil

Pancake coils
Pancake coils are the standard soft annealed coils and available in 15 metre lengths and on request. They are particularly suitable for merchandising as they are individually  packed in polythene bags. Because of their shape they are easy to be stored and handled.

Straight lengths
Available in 5.8 metre lengths and on request usually in “hard” temper or if specified – “soft” temper. Streamline Mueller has the capacity to cut lengths as short as 1/2″ accurately. Mill tolerances achievable are to within ± 0,0625″ (1.59mm).

Level wound coils
Level wound coils are especially adapted to long production runs and can be supplied in lengths over 300 metres (1000ft). The chief advantage is the consistency of diameter which enables the coil to be played off a mandrel for long production runs.

Supplied in ASTM:
ASTM Standard (1/4″, 3/8″, 1/2″, 5/8″, 3/4″, 7/8″, 1″, 1 1/8″, 1 1/4″, 1 3/8″, 1 5/8″, 2 1/8″, 2 3/8″, 2 5/8″, 3 1/8″, 4 1/8″).
BS Standard (British Standard) (6mm, 8mm, 10mm, 12mm, 15mm, 22mm, 28mm, 35mm, 42mm, 54mm, 67mm, 76mm, 108mm, 133mm, 159mm.


Insulflex is a flexible and light weight elastomeric nitrile rubber material designed for thermal insulation. Insulflex insulation is generally black in colour, other colours are availble upon request. The product comes in tubing, roll and sheet form.The extruded flexible tubings are specially designed to fit the standard diameters of copper, steel and PVC pipings. Sheets are available in standards precut sizes or in rolls.

Use in:

Insulflex insulation is an expanded closed cell structure provides the ideal and most efficient vapour barrier for the prevention of condensation or frost formation on cooling systems, chilled water and refrigerant lines.

Insulflex insulation also prevent retards heat loss for hot water plumbing and heating, dual temperature piping systems. It protects pipes by acting as a vibration damper and giving protection against corrosion by atmospheric and industrail environment.

Insulflex insulation with its inherent flexibility makes it ideally suited for the insulation of large surface area such as tanks, irregular shaped vessels, air-ducts and large diameter pipes.



Characteristics and Advantages :

Insulflex insulation material has been specially designed to provide the following features :

  • Its low thermal conductivity (k Value) which makes it highly efficient and effective in the insulation of cooling or heating systems.
  • The hermatic blister closed cell structure forms an impermeable layer which is in itself a good vapour barrier.
  • It is suitable for appliction within the temperature range of –40 deg to 105 deg C.
  • The material has been specially compounded to be self extinguishing in nature.
  • Insuflex has excellent ozone and ultraviolet ray resistant.
  • It is CFC, chlorine and fibre free and does not cause skin allergy.
  • It is also inert to majority of chemical agents and neutral to pipe metals.
  • The extreme flexibility of material makes installation fast, easy and economical.
  • It is able to withstand tearing, rough handling and severe site conditions.
  • Much lesser space is needed for Insulflex as a thinner wall is required due to its low k value as compared to other types of insulation.
  • The smooth surface of insulflex material gives the finished insulation a net aesthetic appearance.No coating is needed on most indoor installations.
