Thermoplastics are polymers which we use on a regular basis without realising what they are. They are, in fact, plastic materials with high molecular weights which form chains of polymers due to their intermolecular forces. They are pliable and can be moulded into any form by heating them to a specific temperature.
Once the required shape if acquired, they are cooled and then solidify magically retaining the new shape given. Of course to give them the required shape or to mend them, welding services are required. It must, however, be kept in mind that thermoplastics do not melt on cooling. Hence to reshape or reform them, they need to be heated again. On the other hand, this welding services is commonly known in welding metal or steel using a high quality steel supplies.
Some everyday thermoplastics we use
This ability to get recycled increases their utility and also reduces their cost, thereby making them affordable yet durable substitutes of many costly substances. Since mending can also be easily done using welding services they are used to make consumer goods, medical equipments, machine parts, storage and packaging materials etc. In fact, a few of their common types which we see and use in our daily routine are
• Acrylic: This is probably the most widely used polymer and is commonly used as a replacement for glass because it is transparent and also does not break easily. Some of the common objects that we see around us and made of acrylic are aquariums, helmet visors of motorcycles, windows of aircrafts, viewing ports of submarines etc. In the medical sector, it is also used to replace lenses and is a constituent of bone cement.
• Nylon: This is a well-known polymer used as ropes and strings, in making fabrics and carpets etc. In fact it is also used as an affordable substitute for silk and used to make parachutes, clothing, vests etc. Nylon is also used in bulk in the industrial sector to make machine parts, gear wheels etc.
• Polythene: This is another very common thermoplastic we use daily. Due to its strength and resistance to chemicals, it is used to make a number of products. For example artificial joints, bearings, gears and other machine parts and even bulletproof vests are made from it. Other uses in daily life include bottles, gas and water pipes, small bags, sheets etc.
• Teflon: We keep hearing about getting a Teflon coating done on cars and non-stick cookware. It is chemically inert and is hence used to store reactive chemicals and also to minimise friction in gears, ball bearing and bushings.
• PVC or polyvinyl chloride: It is mainly used in the construction industry as drainpipes and gutters, roofing sheets, electrical insulation etc. It is also used to make water beds, pool toys, jackets and even upholstery of furniture.
• Polystyrene: This thermoplastic is commonly used as CD and DVD jackets, in making disposable cutlery, smoke detectors etc. Commonly known as Styrofoam, it is also used to make drinking glasses and architectural models.
