| Magnus automotive fire retardant flooring is specially designed for flooring of public transport automobile vehicles. This plywood is made of selected timber and E1 standard BWP grade adhesive. The chemical treatment of this product delays temperature rise, reduces the evaporation of gases, prevents the oxygen content and flame spread. This plywood is ideally suitable for bus floorings, Berths, Seats, Container Floorings, racks and paneling etc. Application: Interior of public transport buses, city buses, low floor buses, high floor buses, automotive cabin, seats & other optional arrangements and fittings. Length: 2440, 2740, 3050, 3200 mm Width: 1220, 1525 mm Density: 0.62 to 0.65 gm/cm3 |
