Plastic molding gives companies the ability to create parts and components that are customized to their needs. The process generally uses thermoplastics, a type of material known for its versatility. Here are answers to some common questions about this plastic. 

A Guide to Thermoplastics

What are thermoplastics?

A thermoplastic is a polymer resin that becomes flexible when exposed to a certain level of heat and hardens when cooled. The process can be completed multiple times without the material degrading. Polypropylene, acrylic, and polycarbonate are examples of thermoplastics. Garbage bags, sporting equipment, toys, and bottles are among the many products made from them. Thermoplastics can also be used in the 3D printing process.

How are they made?

Thermoplastics are made from monomer resins. That means the material is made of a series of single molecules rather than complex compounds that include many molecules. These resins can be injected into a mold or cut into flat sheets. 

What are the benefits?

Thermoplastics are versatile and can be formed into nearly any shape, including curved surfaces and tubes, when enough heat is applied. Additionally, since the material doesn’t degrade when it is heated or cooled, it can be recycled into new shapes once it is no longer useful in its original form. 

What are the limitations?

Since thermoplastics melt or become pliable amid heat, they are not useful in applications that may be exposed to extreme weather or fluctuating temperatures. For example, many industrial applications require plastics that remain sturdy around heavy machinery that produces heat. Those situations require a different type of plastic with an extremely high melting point.
