list of thermoplastics

Polyester fabrics also highly stain resistant. It is non-toxic and so can be produced to fit FDA grades and be used as containers for consumable goods. It is available in two forms namely flexible and rigid. The forms of vinylchloride are almost unlimited. (x) Pipes and fittings for water service (unsuitable for hot water service because of low softening point). Huge Collection of Essays, Research Papers and Articles on Business Management shared by visitors and users like you. Content Guidelines 2. (iv) They are unaffected by water, inorganic salts, alkalies and many acids. Polypropylene 4. The other reactant is methyl chloride, prepared by chlorinating methane gas. Some typical examples of amorphous thermoplastics are PMMA, PS and PC. PMMA is manufactured by addition polymerisation of methyl methacrylate in presence of a peroxide catalyst. (i) All nylons possess good abrasion resistance. Necessary cookies are absolutely essential for the website to function properly. This thermoplastic comes into its own when a strong, transparent material is required. i.e., Thermoplastics and thermosetting polymers are types of plastic that undergo different production processes and yield a variety of properties depending on the constituent materials and production method. These are applied extensively in automotive, electronics and other industrial sectors. All of these types can be melted down many times and re-shaped into different forms. It has been compounded for a wide range of products and is extremely versatile. Polyethylenes are obtainable as various liquids, gums and tough flexible solids suitable for moulding. The desired products are then hydrolysed and condensed to form silicon polymers. Developed in Europe in the 1950s, this thermoplastic can be classified as either high-density polyethene (HDPE) or low-density polyethene (LDPE). (viii) Although its electrical properties are not so good as those of rubber, it offers more resistance to oxygen, ozone and sunlight. (vi) Freedom from taste and colour and physiologically harmless nature makes polystyrene suitable for use in contact with foodstuffs. Because of their unique chemical properties, thermoplastic materials can be remolded and recycled without negatively affecting the material’s physical properties. Types of thermoplastics include polyethylene (PE), polyvinyl chloride (PVC) and polystyrene (PS), which often are used for packaging. It is stronger and more rigid material than polyethylene owing to the presence of CH3 group attached to the linear molecular chains. Teflon or Polytetrafluoroethylene 5. Also, you may want to use our Plastic Material Selection Guide or Interactive Thermoplastics Triangle to assist with the material selection process based on your application requirements. Below are the most common thermoplastics used in injection molding. How does it work? This category only includes cookies that ensures basic functionalities and security features of the website. PTFE is manufactured by addition polymerisation technique. (iv) They are brittle at low temperature, translucent and flammable. They exhibit good temperature capability as they possess high glass transition temperature, Tg. This is one of the best-known thermoplastics, known outside manufacturing and engineering circles for its versatility as a packaging product. PVC can be manufactured in expanded or cellular form. For all nylons similar nomenclature is used. A small amount of lead salt, lead silicate or lead stearite is blended into the polymer at the compounding stage to prevent the same. Higher density versions tend to be more rigid and heat resistant, making it suitable for. (vi) As insulation in submarine cables and radar lines. Susceptib… It has a variable crystalline structure that allows for a vast range of applications. : Ther difference between these two types of plastics is that Thermoplastics … In order for the method to be flexible, as well as highly reliable, a range of thermoplastics is necessary. They are mechanically weak and have poor chemical resistance. Thermoplastics have been extensively used in numerous automotive and transportation applications. Thermoplastic polymers consist of long polymer molecules that are not linked to each other. plastic. These reviews at the bottom based on personal experience. The silica is reduced to silicon, which is one of the starting materials. (i) High voltage (upto 30 kV) applications. Important thermoplastic materials are described as follows: 1. (iii) High resistivity and dielectric strength. Acrylic is popular for its attractive finish and its versatile nature. Generally, amorphous thermoplastics are less chemically resistant and can be subject to stress cracking. It has a variable crystalline structure that allows for a vast range of applications. Use our interactive properties table below to explore by property group, sort, or compare two or more plastic materials. Polyamide is better known as nylon and is a common material used in fabrics and sports equipment such as nets. Terms of Service 7. Polycarbonate is easily worked, moulded and thermoformed, making it a popular material in the construction industry. (x) Housewares like water jugs, mugs, tumblers, plates, trays etc. Nylon-10 is produced by condensation reaction between hexamethylene diamine and sebacic acid. It is the oldest known plastic and was employed about 3000 B.C. Polyethylene or Polythene 2. Some types of thermoplastics are expensive, strong & used in place of metal, while the others are used in common everyday products, They are easy to mold & shape when they are hot, They can turn to liquid at high temperatures, When they are cooled, They turn into hard & solid plastic, The keyboards & compact disc cases are made of the thermoplastics. Thermoplastics offer many advantages over traditional materials, including: low density; low energy for manufacture; low processing costs; and the ability to make complex shapes relatively easily. This list may not reflect recent changes (). (viii) Fan and blower casing (gas filled polythene). The joints are obtained by solvent welding. having the pr... celluloid. It can be fabricated into desired shapes by hot processing and sintering the polymer powder. Following is a list of types of thermoplastics and their most common uses: ABS (acrylonitrile butadiene styrene): Because this material is lightweight but has high-impact resistance and mechanical toughness, it is often used as a material in toys, appliances, telephones, cell phones, microwaves, musical instruments and safety hats. This is obtained by low pressure polymerisation process. The main advantages and disadvantages of high heat thermoplastics as compared to thermosets are summarized in table below.
