Plastic Materials And Its Important Types | Mechdor

Plastic Materials

'Plastic Materials are the result of a combination of carbon elements reacting with Oxygen, hydrogen, nitrogen, and Other organic and inorganic elements.'

The world is full of plastic. Whether you realise it or not, practically everything you see and use daily is entirely or partly plastic. Your Television, computer, car, house, refrigerator, and many other essential products utilise plastic materials to make your life easier and more straightforward. However, all plastics are not made alike. Manufacturers utilise a variety of different plastic materials and compounds that each possess unique properties.

👇 The 7 most popular and commonly used plastics:

• Acrylic or Polymethyl Methacrylate (PMMA)
• Polycarbonate (PC)
• Polyethylene (PE)
• Polypropylene (PP)
• Polyethylene Terephthalate (PETE or PET)
• Polyvinyl Chloride (PVC)
• Acrylonitrile- Butadiene Styrene (ABS)

 Let's take a look at these plastic materials.

    

Acrylic or Polymethyl Methacrylate (PMMA)                     

PMMA is used in optical devices and products. Acrylic is a transparent thermoplastic used as a lightweight, shatter-resistant alternative to glass. Acrylic is typically used in a sheet form to create products such as acrylic mirrors and acrylic plexiglass. The transparent plastic can be made coloured and fluorescent, not abrasion-resistant, bullet-resistant, UV-tolerant, non-glare, anti-static and many more. In addition to being glass and polycarbonate sheeting, acrylic is seventeen times more impact resistant than glass, is easier to handle and process, and has endless applications.

Acrylic is widely used for:-

• Indoor and outdoor signs
• POP displays and exhibits
• Architectural glazing, skylights
• LED diffusing lighting panels 
• Transporting applications
• Brochure holders
• Shelves and retail fixtures 
• Transparenmanifoldsds
• Frames and display cases

Polycarbonate (PC)

Tough, stable and transparent, polycarbonate is an excellent engineering plastic that is as clear as glass and 250 times stronger than acrylic. Clear polycarbonate sheets are also easily worked, moulded and thermoformed or cold-formed. Although extremely strong and impact-resistant, polycarbonate plastic possesses inherent design flexibility. Unlike glass or acrylic, polycarbonate plastic sheets can be cut or cold-formed onsite without pre-forming nanofabrication. Polycarbonate plastic is a wide variety of products, ts including greenhouses, DVDs, sunglasses, police riot gear, and more.

Polyethylene (PE)

The most common plastic on earth, polyethylene, can be manufactured in varying densities. Each different density of polyethylene gives the final plastic unique physical properties. As a result, polyethylene is used in a wide variety of products.

The four common polyethylene densities:

• Low-Density Polyethylene (LDPE)- This density of polyethylene is ductile and used to make products like shopping bags, plastic bags, clear food containers, disposable packaging, ng etc.

• Medium-Density Polyethylene (MDPE)- Possessing more polymer chains and thus, greater density, MDPE is typically used by gapipespe, shrink film, carrier bags, screw closures and more.

• High-Density Polyethylene (HDPE)- More rigid than both LPDE and MOPE, HDPE  plastic sheeting is used in products such as plastic bottles, piping for water and sewer, snowboards, boats and folding chairs.

• Ultra-high Molecular Weight Polyethylene (UHMWPE)- UHMWPE is not much denser than HDP. Compared to HOPE, this polyethylene plastic is much more abrasion-resistant due to the extreme length of its polymer chains. Possessing high density and low friction properties. UHMWPE is military body armour, hydraulic seals, and bearings, a biomaterial for hip, knee, and spine implants, and artificial ice skating rinks.

Polypropylene (PP)

This plastic material is a thermoplastic polymer and the world's d,s second most widely produced synthetic plastic. Its widespread use and popularity are undeniable because polypropylene is one of the most flexible thermoplastics on the planet. Although PP is stronger than PE, it still retains flexibility. It will not crack under repeated stress. Durable, flexible, heat-resistant, acid-resistant, and cheap, polypropylene sheets are used to make laboratory equipment, automotive parts, medical devices and food containers.

Polyethylene Terephthalate (PETE or PET)

The most common thermoplastic resin of the polyester family, PET, is the fourth-most-produced synthetic plastic. Polyethylene Terephthalate has excellent chemical resistance to organic materials and water and is easily recyclable. It is practically shatterproof and possesses an impressive high-strength-to-weight ratio. This plastic material is in fibres for clothing, containers for food and liquid, glass fibre for engineering resins, carbon nanotubes, and many other products that we use daily. 

Polyvinyl Chloride (PVC) 

 The Third-most produced synthetic plastic polymer, P, VC can be manufactured to possess rigid or flexible properties. It is well known for its ability to blend with other materials. For example, expanded PVC sheets are a formed polyvinyl chloride material that is ideal for products like kiosks, store displays, and exhibits. The rigid form of PVC is commonused ly in construction materials, doors, windows, bottles, non-food packaging, and more. With the addition of plasticisers such as phthalates, the softer and more flexible form of PPVC is used in plumbing products, electrical cable insulation, clothing, medical tubing and other similar products.

Acrylonitrile-Butadiene-Styrene (ABS)

Created by Polymerizing styrene and acrylonitrile in the presence of polybutadiene, ABS is robust, flexible, glossy, highly processable, and impact resistant of thickness from 200 microns to 5mm with a maximum width of 1600mm With a relatively low manufacturing cost, ABS plastic sheeting is typically used in the automotive and refrigeration industries but is also in products such as boxes, gauges, protective headgear, luggage, and children's toys.
