The Plastics & Composites
Division operates in two separate plants: the
Thermoplastics Plant and the Reinforced Plastics/Composites
plant. This division designs, manufactures and
fabricates thermoplastic and glass-fibre reinforced plastics products for
commercial and industrial uses.
Thermoplastics are plastics which are processed and formed by the
application of heat. Some types may be welded. In the
thermoplastics plant various forms such as sheet, pipe, fittings are
fabricated into various products such as hoods, ducting, fans,
stacks, tanks, and pumps.
MANUFACTURING AND FABRICATION
The most commonly used resin is unsaturated polyester, which is
processed as a solution in styrene monomer. The products
use high-strength reinforcements such as glass fibres, which are
available in various forms including mat, cloth, rovings and
FRP products are used in commercial applications including
architectural panels, skylights, decorative panels, roof decks,
cooling towers and water tanks. Chemical-resistant applications
are found in many industries including coal, oil and gas, plant
cooling systems for power plants and petroleum and natural gas
plants, geothermal power plants, pulp & paper plants,
pharmaceutical and chemical processing plants, mining and
mineral processing plants, textile manufacturing plants, and
automotive plants. Other applications are found in ports,
offshore platforms and marine applications. The products made
are tanks, piping, pipe fittings, hoods, ducting, scrubbers,
stacks and tank covers. Photographs of large FRP tanks and pipes
are shown on the front cover.
The plant also produces dual-laminate products such as process
vessels, tanks, scrubbers, pipe and fittings using a
thermoplastic inner liner, which is overlaid with glass-fibre
reinforced polyester to enhance the structural strength.
