Pipe with PEX / EVOH anti-diffusion layer

Pipe with PEX / EVOH anti-diffusion layer

Overview

Pipe structure with PEX / EVOH anti-diffusion layer:

The first inner layer is made of PEX cross-linked polyethylene. The polyethylene of the inner layer was crosslinked using the organosilane method. The inner (working) layer has a crosslinking degree of 65%.

The second layer is a high-quality adhesive composition that has good adhesion and ensures a reliable connection of all layers.

The third layer is EVOH (ethylene vinyl alcohol copolymer), which prevents oxygen diffusion.

PEX material (English PE - PolyEthylene - polyethylene, X - Cross-linked - cross-link) is cross-linked polyethylene. This material is obtained by special processing of polyethylene raw materials by chemical or physical methods, due to which additional, much stronger cross-links between molecules are formed. Such crosslinking significantly improves both the chemical and physical characteristics of the material, due to which it becomes more durable and heat-resistant.

PEX pipes are produced by the so-called silane process, when the molecular bonds are changed under the action of a catalyst, which is the silane.

A distinctive feature of PEX pipes is their ability to regain their shape ("shape memory") after deformations.

The advantages of cross-linked polyethylene pipes are high strength and heat resistance, resistance to corrosion, overgrowth, siltation and salt deposition; high chemical resistance, resistance to mechanical damage, low roughness, high noise absorption capacity, low thermal conductivity, high plasticity and low weight, technological and economical installation.

Compliance with the passport operating conditions guarantees a 50-year service life of the products.
