Take Advantage Of Modern Thermo Plastics

By Genevive B. Mata


Modern technology has made some pretty amazing materials possible. Thermo Plastics profit from the facility of being heated countless times. When hot these substances become supple and pliable. Upon being cooled, these polymers solidify but are nevertheless capable of being reshaped. This capacity comes to pass due to the absence of horizontal links through the polymer sequences.

Numerous well known materials are varieties of thermoplastics. These include polyvinyl chloride (uPVC), polyamide (nylon), polystyrene, polymethyl methacrylate (acrylic) and polypropylene. World famous brands like Plexiglas, Lucite and Perspex are cases of acrylics we routinely see used as substitutes for glass in functions such as aquariums, aircraft windows and visors in motorcycle crash-helmets.

The compounds of nitrocellulose and camphor, first created in 1856, were considered to be the first thermoplastics and known as celluloid. Photographers and movie makers exclusively used celluloid before the advent of acetate in the 1950s. Today, celluloid is more commonly used in the manufacture of ping pong balls, guitar picks, accordions and other musical instruments.

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.

Thermo Plastic forms an essential component fibre of this modern world. Either when found in the shape of Lego bricks (the building blocks of modern life), or as durable, lightweight eye-glass lenses, these compounds alter your view of your world. Their capacity for recycling is another significant feature in the hunt for eco-friendly materials.
