Thermo Plastics Are Very Convenient

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.

Several renowned materials are types of thermoplastics. Included amongst these are polypropylene, polystyrene, acrylic (polymethyl methacrylate), polyvinyl chloride (uPVC) and polyamide (nylon). Brands that are known throughout the world like Lucite, Perspex and Plexiglas are instances of acrylics routinely seen used as replacements for traditional glass in items such as crash-helmet visors, aquariums and aircraft windows.

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.

Alexander Parkes is generally credited with being the founding father of the plastics industry. His patented Parkesine clothing water proofer was the original bulk object forming material. Low production costs, toughness, flexibility and resistance to oil, water and dilute acids made celluloid hugely successful in the late 19th Century in the manufacture of mass produced goods such as piano keys, billiard balls, combs, brush handles and eye-glass 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.

PBI (polybenzimidazole) is another synthetic fibre with outstanding toughness, thermal and chemical stability. Polybenzimidazole is perfect for items that need very high melting points and has applications for protective clothing, aircraft wall fabrics and fuel cell membranes. Polytetraflouroethylene (PTFE) is more usually known under the trade name Teflon as the non-stick coating 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.
