Biomax Polyethylene terephthalate polyester DuPont Polyester >> Unsaturated >> Aromatic ADHESIVE >> Hot-melt To meet this challenge, DuPont scientists have created a new family of highly versatile polymers based on polyethylene terephthalate (PET) technology and known commercially as DuPont Biomax® hydro/biodegradable polyester. Depending on the application, up to three proprietary aliphatic monomers are incorporated into the polymer. The monomers create weak spots in the polymeric chains, thereby making them susceptible to degradation through hydrolysis. The large polymer molecules are cleaved by moisture into smaller molecules, which are then consumed by naturally occurring microbes and converted to carbon dioxide and water. The sheer number of potential applications for Biomax® is immense. Because it can be made into fibers, films or resins, it is suitable for a range of single-use products, including domestic wipes, yard waste bags, the top and back sheets of disposable diapers, blister packs and disposable eating utensils. It can be used to create geotextiles, agricultural films, seed mats, plant pots and bags that cover ripening fruit. It can find application in coated paper products such as disposable plates and cups, aluminized films for food packaging and hot-melt adhesives. It is also suitable for thermoformed packaging, blown bottles and injection-molded objects. Product properties are diverse and customizable, but are generally tailored to mimic polyethylene or polypropylene. Biomax® is soft, pliable, low in noise and has a good hand. Melting points are high for a degradable material, generally around 200°C, which opens up a range of processing options. It can be formulated to be as low in strength as low-density polyethylene or as high as half the strength of DuPont Mylar® polyester film. Elongation can range from 50 to 500 percent. Hydro/biodegradable, highly versatile polyethylene terephthalate (PET)polyester. Used in hot-melt adhesives. Can be degradated through hydrolysis. Possesses softness, pliability, low noise, a good hand and high melting point.
