A fully biodegradable resin for rigid moulding applications

Greater than 98% biodegradability when tested to ISO14855

Can be used for injection moulding and profile extrusion

BIOGRADE B-M is a fully biodegradable plastic based on a blend of thermoplastic starch (TPS), aliphatic polyesters (AP) and natural plasticizers (glycerol and sorbitol). 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. The resin does not contain polyolefins.

Applications

Biodegradable injection moulded products such as cutlery, toothbrushes, combs, shavers, golf-tees, plant markers, etc.

Extruded tubes and rods

Biodegradable stakes and pegs

Biodegradable tags

Extruded pipes

Injection moulded caps and closures

Compostable rigid products if wall thickness is kept below 1 mm.
