CERTIFIED PRODUCTION PROCESSES
The SAERTEX-LINER® consists of a complex of several fibreglass-reinforced laminated sheet layers. For production in our works we only use high quality glass which is permanently resistant to chemical agents or corrosion.
The liners are fabricated to the nearest millimetre and impregnated in the works with an ISO-NPG polyester resin or vinyl ester resin for very aggressive sewage. The advantages are obvious.
On one hand, the entire impregnation process is subject to the strictest controls, so elimination production failures from the outset. On the other hand, th use of chemicals on the site becomes completely unnecessary - an important aspect with regard to the safety of installers and residents and for the protection of the environment. Both resins are suitable for UV curing and warm curing with steam.
The reinforcing glass fibres are embedded in the ideally adapted resins. Hose liners made of synthetic fibres, such as polyester-needled felt, just serve as a base material for the resin and do not have any reinforcing properties. This is why the material specific values of the SAERTEX-LINER® are substantially higher when compared to traditional hose liners produced with synthetic fibres.
