SO.F.TER. OBTAINS CSTB APPROVAL FOR WINDOW GASKETS
Two specific grades for the production of resistant, durable and non-stainable gaskets.
SO.F.TER. is glad to introduce the new LAPRENE (TPE-S) for the production of gaskets for windows and
glazed façades, approved by the prestigious French certification authority CSTB (Centre Scientifique et
Technique du Batiment).
The new products, called LAPRENE 83E200A60/CB (natural color) and LAPRENE 83E29ZA60/CB (black color),
have been developed to meet the high quality standards of the gaskets for building sector: high elastomechanical properties, excellent weathering and UV resistance and durable performance are the main
strengths of the new LAPRENE. Moreover, thanks to the special formulation, gaskets leave no stain on
adjoining surfaces and can be installed on any kind of window fixtures (wooden, aluminum, PVC).
Both approved grades have successfully passed rigorous physical-chemical controls, UV ageing tests, and
temperature resistance tests as prescribed by the CSTB standard EC02, obtaining the approval as materials
of “Class 4 + 5” (the highest of the standard), with operating temperatures from -25 °C to 100 °C.
CSTB is one of the most important French certification authorities for the building and construction sector.
The CSTB approval is a fundamental requirement to operate in the French market and is recognized at a
European level as a synonym for product and process quality.
