AlphalinerECO - Styrene-free

Following three years of development, RELINEEUROPE has achieved series maturity for a hose liner based on styrene-free resin. Using styrene-free resin provides an efficient and environmentally-friendly alternative to styrene-based systems. Styrene-free products are an ideal solution for all use cases with high demands on emissions (in particular after liner curing) and flammability


AlphalinerECO is a styrene-free vinyl-based GRP hose liner specially designed for rehabilitating waste water sewers with unique demands. In addition, it provides the following:

  • Excellent chemical resistance to communal waste water
  • High mechanical characteristics for long-lasting resilience
  • Unique wearing course on the inner liner surface
  • Optimum solution for circular, ovoid, square, or custom cross-sections
  • No styrene smell


Alphaliners are manufactured in continuous production up to approx. 300m of individual lengths. Using pre-impregnated glass fibre tapes, liners with a diameter of DN150—DN1500 are rolled into a continuous flexible hose.
We use a highly resistant styrene-free vinyl-based polyester resin (UP; classified as per DIN EN 13121 in group 4; DIN 16946-2 type 1140; DIN 18820 group 3) as well as corrosion-resistant ECR glass fibres.

On their inner liner surface, Alphaliners have a special wearing course in compliance with DWA-A 143-3 and DIN EN ISO 11296-4. This wearing course is achieved by using a vylene-bonded high-grade resin layer of at least 0.5mm. Currently, Alphaliners are the only hose liners in the world offering a defined wearing course thickness.

Alphaliner1800-ECO has excellent mechanical characteristics. This qualifies it to withstand the highest structural stress loads at a comparatively small wall thickness.

We offer you the following models:
