An Insight into Different Types of Thermoplastics and Their Applications

Thermoplastics are made of resins that are first heated to melt them down, then molded into the desired shape and cooled to form the final plastic products. One of their main advantages is that there are many kinds of resins that can be made into plastics, and each resin has different properties that serve the needs of the final product they are made into. Common applications include FAR rated plastic, knife sheath plastic, airplane plastics, etc. Here are some common thermoplastic materials and their applications:

Acrylic Plastics

Acrylic is highly transparent and durable at the same time, making it a perfect replacement for glass which is brittle and can pose a risk when shattered. Acrylic products are shatterproof and breakproof, so they last long and can withstand heavy pressure. Acrylic plastics are used to make looking glass, building window glass, car windshields, airplane window glass, submarine glass, and car headlamp lenses.

Polycarbonate

Polycarbonates are tough, stable and heat resistant, making them perfect for a wide range of applications such as knife sheath plastic, molding plastic, appliance covering, automobile parts and many more. Although they are heat and flame resistant, it is recommended not to expose them to direct sunlight for a long time to prevent the composite from weakening.

Polypropylene

It has more applications, both industrial and commercial, than any other variant of thermoplastic. They are highly modifiable in terms of strength and durability, hence they are used for making plastic containers, file folders, storage boxes, heat resistant coatings, medical equipment exteriors, electric cable insulation, and piping systems. They are quite resistant to heat and cold and are best suited for little higher than normal temperature applications.

Polyethylene

Just like polypropylene, polyethylene is also widely useful in a variety of applications. They carry similar properties of polypropylene, but they have less durability and are hence cheaper. They are highly chemically resistant and very tough and can be made into almost anything from FAR rated plastics to garbage bags to tough, rigid pipes and machine parts. The density of polyethylene can be readily adjusted, quickly turning them hard to soft and vice versa during the thermoforming process.

Polyvinyl Chloride

Polyvinyl chloride, also known as PVC, is a versatile thermoplastic that can be made either very soft and thin like a film, or hard and rigid like a tile. This gives them crucial places in diverse applications such as manufacturing of appliance exteriors, drain pipes, plumbing pipes, electrical cable pipes, insulating material, inflatable balloons and inflatable signs, pool toys, rubber toys and many more.

Custom-Made Thermoplastic

While these are generalized thermoplastic variants, many companies make their own custom thermoplastic that caters to specific applications such as aircraft interior materials, fireproof materials, plastics for cleanroom wall linings, high strength custom thermoplastic and so on. They use their own composite resins for the same, and achieve a finer degree of perfection over regular thermoplastics. Businesses who want such custom thermoplastics tailored to their own needs can contact such businesses that make their own thermoplastics.
