Plastic is the most used product worldwide, made into various consumer products we use every day. From being used in making mobile and other consumer electronic products to being made into medical equipment, to being fabricated into various military applications; making itself a versatile product in society.
Plastics are made using the derivatives of petroleum and natural gas. These are further processed into various forms of polymer chains such as polyethylene, polyvinyl, etc. Using certain formulations and manufacturing techniques, different kinds of plastic polymers.
Various plastic products are made by using plastic granules in manufacturing. These are small beads or granules of one or many types of polymers.
The various types of plastic granules used by the plastic granule manufacturers in India are:
Made by polymerization of the organic compound gas propylene using the Ziegler-Natta or metallocene as the catalyst. The temperature and pressure during the manufacturing decide the grade of the polymer granules.
Polypropylene is the second most used plastic worldwide after polyethylene or polythene with a global market worth of more than $125 billion.
The advantages of polypropylene which it brings in the products are:
- Lightweight or lower density
- The flexibility of the material
- Good resistance to the heat
- Fatigue resistance
The applications of polypropylene vary from being used in industries such as:
- Household appliances
- 3D printing
- CNC machining
- Electric cables
Acrylic or polyacrylates is a type of elastic polymer made from acrylates. Acrylates are the monomers made up of salt, esters, and conjugate bases of the vinyl groups comprising acrylic acid. The vinyl group’s properties are that it is great for the polymerization process.
The plastic granules for the acrylic are manufactured by treating the acrylic acid with corresponding alcohol in the presence of a catalyst.
The properties of the acrylic polymer are:
- Great transparent and optical clarity
- Excellent sunlight and weather resistance
- Great elasticity
Applications of the acrylic polymers are:
- Acrylic paints, both for art and commercial usage
- Acrylic fibers
- Acrylic resins
- Decorative items
- POS displays
Polycarbonates are a group of carbonate chain groups made by reacting the bisphenol and phosgenes. Around 1 billion kilos of polycarbonate is manufactured every year. Polycarbonate is known for its high durability and inertness to various external conditions of stress and weather.
Advantages of polycarbonate exhibited:
- Toughness against external stress and weather
- Resistance against chemicals
- Lightweight in density
Applications of polycarbonate are:
- Memory storage
- Security and Defence equipment
