DaniMer Scientific, a sustainable company, has released a breakthrough bio-based label adhesive, which has been developed to address the needs of the polyethylene terephthalate (PET) container recycling industry.
The new DaniMer 92721 label adhesive uses renewable building block chemicals from two major suppliers: bio-succinic acid from Myriant and Susterra Propanediol from DuPont Tate & Lyle. DaniMer combines these two chemicals into a patent-pending, proprietary resin material that promotes the advanced properties of the new adhesive.
The 92721 label adhesive has more than 50% of renewable content and it dissolves entirely in PET flake caustic wash recycling processes without any clumps. DaniMer 92721’s rheology allows the adhesive to work in present adhesive systems at below 325F temperatures. Thus, the innovative adhesive helps to overcome the issues associated with PET container recycling.
Conventionally, succinic acid is derived from petroleum and it is used in a broad range of applications, including manufacturing of flavors, detergents, surfactants, fibers and polymers. The high purity bio-succinic acid from Myriant is an ideal substitute for petroleum-based succinic acid. Several customer studies have revealed that Myriant's bio-succinic acid is chemically the same as petroleum-based material and in addition, it is more cost-competitive and environmentally friendly.
The US Department of Agriculture has certified DuPont’s Susterra Propanediol as 100% bio-based material and it is ideal for companies that are looking to add renewable content into their products.
DaniMer Scientific announced the commercial launch of DaniMer 92721 label adhesive at the Nova-Pack 2012 Conference, which was held in Arlington, Virginia from June 7 to 8.
