Jute Reinforced Composites – Natural Fibre Thermostat Composite (NFTC)

Jute Composites are used for manufacturing Hot Pressed Rigid Jute Boards made out of Jute Hessian / Felt as reinforcing material and PF/MF/MUF/PUF resins as binder. These boards are suitable for Panelling, Roofing, Flooring , Moulded products and many structural applications. These are wood substitute. Unique properties of these boards are fire retardant, anti bending, anti water absorption and abrasion resistant.

Different types of Raw Materials are procured from different suppliers and are checked for various parameters mentioned in their test certificate for its acceptance. After the raw materials are accepted as per its requirements it is kept in the store. With different fillers, slurry is made by mixing Phenolic Resin and also Melamine Resin separately in required proportion in normal seasonal temperature and is kept in a tray of the impregnation plant separately.

Then in a impregnation plant we impregnate Jute Hessian Cloth with Phenolic Resin and Fibre/Polyster Cloth with Melamine Resin separately with adequate temperature raised in the chambers by the boiler. This resin coated Jute Hessian Cloth and Polyster/Fibre Cloth is cut into required sizes with the help of a sizing machine.

After that we place impregnate Jute Hessian Cloth and Fibre/polyster cloth in the mould of the Hydraulic Press one above another as per thickness required by customer. In the Heated moulds pressure and temperature is adjusted and after cooling the sheets are taken out. After its normal curing time the sheets are cut into sizes with the help of trimming machine and the sheets are stacked in Finishing Area for the Internal Test and dispatch. These sheets are coloured with prima and spray painting of the desired colour to look more decorative and elegant.

The highlights of Jute Composites are

  • Eco friendly

  • Multi Utility

  • Stronger of wood or its substitute

  • Maintenance – free longer life

  • Fire retardent
