Product Detailed
A fully biodegradable resin for moulding and extrusion applications. For use in applications where compostability is required

Biograde T-BM

Rigid  Moulding or Sheet grade Resin-Biodegradable

A fully biodegradable resin for rigid moulding and extrusion applications.For use in applications where compostability is required


BIOGRADE TBM is a fully biodegradable plastic based on a blend of thermoplastic

starch (TPS), aliphatic polyesters (AP), filler 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.


Injection moulded products such as cutlery, toothbrushes, combs, golf-tees, etc.Horticultural products such as flower pots and stakesInjection moulded caps and closuresExtruded sheet for disposable plates and produce traysExtruded tubes for aquatic applications

Processing Conditions

BIOGRADE TBM resin can be processed on standard injection moulding machines or extrusion (sheet or profile)

Suggested Max Moisture (%)           0.2

Middle Temperature (°C)          160 to 170 deg.C

Front Temperature (°F)             140 to 150 deg.C

Nozzle Temperature (°C)           170 to 180 deg.C

Processing (Melt) Temp (°C)            160 to 165 deg.C

Mold Temperature (°C)             10 to 15 deg.C

Specific Instructions for Moulding of BIOGRADE T-BM 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 T-BM resin can be used as the last cleaning step, after which the temperature can be adjusted to the correct settings.

Other Comments

Printability of Biograde TBM is excellent without the need for surface treatment such corona discharge.Wet TBM resin should be dried at 60-70 deg.C for 2-3 hrs before processing.
