TPEs boost environmental credentials via starch blending

Thermoplastic elastomers (TPEs) for injection molding applications feature reduced environmental burdens through the addition of a 30-50% loading of starch. Supplied by Cereplast, Inc. (El Segundo, CA), the two grades on offer are Hybrid 111D with a 30% starch loading and Hybrid 112D with a 50% starch loading. Both grades are soft and pliable, offering stretch with some recovery for soft grip applications such as handles for bicycles and tools, cosmetics packaging, housewares, household appliances, footwear and automotive applications.

"We are enthusiastic about the addition of TPE starch blends to the Cereplast Hybrid Resins family, as we continue to expand our line of bioplastic resins to provide low carbon footprint products to the marketplace," says Cereplast CEO and Chairman Frederic Scheer. "In the next few months we will also introduce polyethylene hybrids, which will round out our product offering, furthering our leadership role for hybrid resins in the bioplastics industry and meeting the demands of our customers for the properties and pricing that they desire."

Furthermore, Cereplast has also introduced a new category of bioplastics with what is claims to be the first ethylene-vinyl acetate (EVA) starch hybrid resin. Hybrid 651D is a tough, soft touch, pliable material that is ideal for extrusions and soft injection moldable applications.

Hybrid 651D is a proprietary formulation of EVA and industrial starch, which is compounded on state-of-the-art mixing equipment. Hybrid 651D can be used for the manufacture of consumer goods and packaging, footwear, handbags and other fashion accessories, as well as wire and cable insulation, soft plastic goods such as tubes and hoses and adhesion layers for multi-layer films.-[email protected]
