Take Advantage Of Modern Thermo Plastics

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.

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 fusion of camphor with nitrocellulose, first fashioned in 1856, was deemed as the original thermo plastic and designated as celluloid. Film production and photography used celluloid alone prior to the acetate's appearance during the latter half of the 20th century. Currently, you will more probably find celluloid in the manufacturing of accordions and various musical instruments; guitar plectrums and table tennis balls.

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.

Recently, Acrylonitrile Butadiene Styrene, or ABS for short, is more often used as a replacement for celluloid in wares including appliances, telephones and toys. Another man-made material with extensive purposes is nylon. This polyamide can be substituted for silk when fabricating bullet-proof apparel, pantyhose and parachutes. Ropes, musical strings, rugs and carpets can be constructed using nylon fibres. Nylon in bulk form can be sculpted into power tool cases, machine screws and gear wheels.

Polybenzimidazole (PBI) is one more synthetic fibre boasting excellent stiffness, chemical and thermal stability. PBI is ideal for items requiring an extremely high melting point and is functional for fabrics used in aircraft walls, protective clothing and the membranes in fuel cells. PTFE (Polytetraflouroethylene) is more regularly known by the trademarked name of Teflon as cookware's non-stick coating.

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.
