A Hybrid resin for rigid moulding and extrusion applications where Biodegradability is not required. For use in applications where the use of renewable resources are desired. Can be used for injection moulding BIOGRADE DM is based on a blend of thermoplastic starch (TPS) and polyolefin’s. This grade of resin is compatibilised to offer a high level of mechanical strength, good elongation properties and toughness. The resin is based on corn starch which is a renewable material. Applications Injection moulded products such as cutlery, toothbrushes, combs, shavers, golf-tees, etc. Stakes and pegs Horticultural products such as flower pots and stakes Injection moulded caps and closures Disposable plates and produce trays&& |
