Technology Process

Natural Fibre Thermostat Composites – Jute Reinforced Composite (NFTC)

  • The sheets shall be sufficiently robust to withstand the normal handling during assembly on coaches. The sheets shall not crack or fracture when worked by ordinary wood working tools or machinery.

  • The sheets shall be weatherproof and shall not loose shape or rot in service. They shall also withstand attack by vermin. The sheets shall not wrap, specially delaminate or blister. Expansion or contraction due to thermal changes may be negligible.

  • The sheets shall have one paintable surface specially prepared for apply the white paint and shall be suitable to receive ready mixed paints, Cellulose lacquer and natural or synthetic enamel.

  • Unless otherwise specified the thickness of sheets shall be 1.5 +0.3 /- 0m. The length and width of the sheets shall be as agreed to between purchaser and the manufacturer. The tolerances shall be ± 10mm for length and width. The out of squareness of the sheets shall not exceed 10mm/1500mm length.
