High MFI PP

The composite has the good properties of plastics such as water resistance, extrudability and formability. Presence of cellulosic filler keeps density of the composite low. It is paintable using regular enamel paints. Its scrap is recyclable

RAW MATERIALS

1. Agricultural waste such as wood flour, saw dust, rice husk, cotton plant stalk powder, jute stalk powder, etc.
2. Polyethylene or polypropylene scrap in pellet form or as output from grinder or agglomerator.
3. A small proportion ~5% of a polymeric wetting agent and viscosity modifier.

TECHNOLOGY

Manas have carried out development work on their modified twin screw extruder with a separate machine for drying wood flour and compression moulding press to prove the technology. Commercially a modified Twin Screw Extruder and specially designed dies for profile extrusion will be required. Compounded granules can also be injection moulded.

LIKELY APPLICATIONS

Panels for interior partitions, Doors / Windows for outdoor exposure and industrial environment. Pallets for material handling. Pots for gardening / plantation (decorative), Table tops, moulded drawers, shelves etc.

The product, being composed of more than 20% Agri waste, does not attract any excise duty currently.
