The Germany headquartered chemical supplier has launched Magnopal Pure A, an environmental-friendly, film-forming bio-polymer based on vegetable biomass.

TFL said its new Magnopal Pure A is produced with sustainable chemistry, so it is free of acrylates, formaldehyde, phenol and naphthalene, with the bio content (BC) of the dry matters reaching 93% using the DIN EN 16785-2 material balance method. The chemical supplier said the product has not only been designed to substitute fossil fuel-based polymers, but also offers interesting economic application features for a wide range of different leather articles.

According to TFL, Magnopal Pure A is a primary ingredient of the wet end process and can be combined with other products from the "TFL Pure-range", aiming for articles with a very low impact on the environment such as Coripol Pure L (fatliquoring agent for soft leathers based on phospholipids; BC=79%), Coripol Pure V (fatliquoring agent for tight leathers based on vegetable seeds; BC=82%), Coripol Pure F (fatliquoring agent for soft leathers based on aquatic biomass; BC=91%), Sellasol Pure H Liq (retanning agent based on animal, and vegetable hydrolysates; BC=97%), and Sellasol Pure M (filling agent based on bio-protein; BC=100%).

Magnopal Pure A is suitable for all kinds of leather articles such as lightweight articles, shoe and leather goods, waterproof leathers, automotive and upholstery leathers as well as garment and glove leathers. According to TFL, it improves the tightness of the fibre structure and is therefore also suitable for retanning fine and smooth grain articles with even grain break after milling. It enhances shade intensity, levelness and defect coverage in the retanning process.
