Benefits
Environmental
SAERTEX-LINER® ENVIRONMENT is impregnated with styrene-free vinyl ester resin, making it ideal for UV-CIPP rehabilitation of pipes in environmentally sensitive applications
Industry leading mechanical properties
This styrene-free liner has exceptional mechanical properties, making it suitable for various applications. It features a long-term circumferential E modulus of 9,450 N/mm² (1,370,000 psi) and an impressive preliminary retention factor of 1.37 (73%) after 2,000 hours of testing.
DiBT approved
SAERTEX-LINER® ENVIRONMENT is the first fiberglass-reinforced pipe liner impregnated with styrene-free VE resin on the market approved by the German Institute for Building Technology (DiBT).
Installation-friendly construction
The construction of SAERTEX-LINER® ENVIRONMENT allows higher pulling forces and prevents the liner from overstretching. Its low weight makes for easier handling, and the lower wall thicknesses shorten curing times. The “FastPlus” option saves even more installation time because the inner foil stays in place after curing.
