Biograde B-LM

 

·        A hybrid masterbatch with high content of renewable resources and Polypropylene (PP) for moulding rigid products where Biodegradability is not required.

·        For use in applications where the use of renewable resources or sustainability are desired.

·        Can be used by blending BLM masterbatch with PP in injection moulding and extrusion applications.

 

BIOGRADE B-LM 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. 

 

·        Injection moulded products such as cutlery, toothbrushes, combs, shavers, golf-tees, etc.

·        Stakes and pegs

·        Horticultural products such as flower pots, planters and stakes

·        Injection moulded caps and closures

·        Sheet extruded products such food trays, tubs, disposable plates, strapping and labels

·        Blow moulded bottles and toys

·        Profile extruded products such as candy sticks and disposable drinking straws

 

 

BIOGRADE B-LM masterbatch can be blended with PP and processed on standard injection moulders, profile extruders, blow moulders, and or sheet extrusion lines.

Specific Instructions for Moulding of BIOGRADE B-LM Resin:

 

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

 

 

 

1.        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.

2.        Wet resin should be dried before processing to limit degradation induced by water (hydrolysis).

 

 

 

BIOGRADE B-LM is not a Biodegradable Polymer. While it is suitable for the manufacture of injection moulded or extruded products, it is not intended for ultimate disposal in commercial composting facilities. If Biodegradability is required, use of Biograde B-M or TBM resin is recommended.
