biodegradable and compostable resin
Product Detailed
A fully biodegradable resin for rigid moulding applications Greater than 98% biodegradability when tested to ISO14855

Biograde B-M

A fully biodegradable resin for rigid moulding applicationsGreater than 98% biodegradability when tested to ISO14855Can 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.  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.

 Specific Instructions for Moulding of BIOGRADE B-M Resin:

Before moulding the resin, the injection moulders barrel needs to be purged and cleaned of residual polyethylene or other polymers and then the BIOGRADE B-M resin can be used as the last cleaning step, after which the temperature can be adjusted to the correct settings.

Other Comments

The mouldings need to condition for 1-2 days after processing to develop their full strength.  During the conditioning the starch component reabsorbs its moisture content making it more ductile.BIOGRADE B-M resins can be blended with natural fibres such as flax, hemp, sisal and coconut hair (coir) to add reinforcement and to assist with water-wicking into thick section mouldings.Wet resin should be dried before processing to limit degradation induced by water (hydrolysis).
