Everberg, Belgium - Leading acoustic flooring group WPT GmbH has developed a new range of soundproofing materials for flooring, with improved environmental credentials, in collaboration with Huntsman Polyurethanes.
Huntsman says German company WPT is a "world-leader in polyurethane-based acoustic systems, decoupling mats and resilient floor coverings." Its soundproofing materials are used under parquet, laminate, tile and stone floors to cut noise.
These products have the durability of PVC-based products, but floors based onWPT's soundproof system are also resilient, hard-wearing and far easierto clean and maintain. According to Huntsman, this makes them "idealfor use in heavy footfall environments such as hospitals, airports,schools, the retail sector, office space, hotels and leisure amenities."
Now the company's ECOLine range of sound-reduction and decoupling mats are better for the environment and less exposed to fluctuating oil prices, Huntsman notes in a 10 March statement.
To develop ECOLine, WPT called on Huntsman Polyurethanes, with a key challenge in replacing a petrochemical-based polyester polyol with a polyether polyol derived from renewable vegetable oils.
Huntsman identified its Suprasec 2385 MDI (methylene diphenyl diisocyanate) as able to give the low viscosity, high linearity and consistent performance needed to help WPT make the transition from polyester to polyether. The result is a range of eco-friendly sound reduction flooring systems based on renewable polyol resources, said the isocyanate supplier.
"As a company committed to sustainability, WPT is absolutely delighted that Huntsman has been able to help us switch to using vegetable oils as the main raw material for our acoustic systems," said Georg Kruse, managing partner of WPT. "Since the late 1990s WPT has developed a highly productive working relationship with Huntsman Polyurethanes ... by enabling WPT to develop innovative acoustic systems and bring to market high quality, customised products such as ECOLine, Huntsman is helping us retain our lead at the forefront of our sector," Kruse added.
Describing SUPRASEC MDI as "an incredibly versatile material that has been used extensively across the flooring sector, Alfred Rasche, sales manager at Huntsman, added: "It can help manufacturers like WPT create hard-wearing, aesthetically pleasing, structurally sound flooring solutions that meet strict environmental regulations."
Flooring manufacturer WPT, formed in 1999, and based in Detmold, Germany, has capacity for 11 million sq.m/annum, making it one of the largest suppliers of acoustic systems in Europe. With its in-house research and testing laboratories, WPT can develop customised products and solutions, base on three core product areas: Soft Sound, an innovative sound-reduction and decoupling product; SRL (Sound Reduct Layer) Mats with insulating and extreme noise-reduction properties; and PURLINE products that are claimed to be exceptionally hard-wearing.
