Thermo Plastics Can Prove Vital For You Manufacturing Needs

By Genevive B. Mata


Having the right material for every job is essential. Thermo Plastics benefit from the capacity to be heated many times. When heated these materials become soft and malleable. Upon cooling, these polymers harden but are still able to be reshaped. This facility arises from the lack of links horizontally between the polymer chains and can be used for a wide variety of applications.

Many well known substances are forms of thermoplastic. These include uPVC (polyvinyl chloride), nylon (polyamide), polystyrene, polypropylene and acrylic (polymethyl methacrylate). Household brands such as Perspex, Plexiglas and Lucite are examples of acrylics that are used as glass substitutes in applications such as aircraft windows, aquariums and motorcycle crash-helmet visors.

The amalgams of camphor and nitrocellulose, first formed in 1856, were deemed as being the original thermoplastics and named celluloid. Film makers and photographers used only celluloid prior to the arrival of acetate during the 1950s. Nowadays, it is more likely to find celluloid being used to manufacture table tennis balls, accordions, guitar picks or other musical gadgets.

The founding father of modern plastic production is generally acknowledged to be Alexander Parkes. The first material used to bulk form objects was the patented water proofer for clothing, Parkesine. Flexibility, toughness, low production costs as well as being water-, oil- and acid-resistant meant that celluloid was enormously successful at the end of the 19th Century for the construction of mass produced merchandise such as billiard balls, piano keys, brush handles, combs and spectacle frames.

Nowadays, ABS (Acrylonitrile Butadiene Styrene) is more commonly used than celluloid in products including telephones, toys and appliances. Nylon is another plastic material that has widespread uses. It is an alternative to silk for use in parachutes, stockings and flak jackets. Carpets, ropes and musical strings can be made of nylon fibres, and in bulk form it can mould gear wheels, machine screws and casings for power tools.

Thermal and chemical strength combined with excellent rigidity are the beneficial characteristics of polybenzimidazole (PBI). This synthetic fibre is flawless for objects requiring exceptionally high melting points and is practical for use in the walls of aircraft, protective gloves and other clothing as well as the membranes of fuel cells. Teflon is the brand name most people recognise for PTFE or polytetraflouroethylene when applied as a non-stick protection on cookware.

The range of Plastics is an intrinsic part of the fibre of the modern world. Whether to be found as a building block of contemporary life as a Lego brick, or as lightweight, durable spectacle lenses, these polymers change the way you see your world today. Their ability to be recycled is another important aspect in the search for eco-friendly materials.
