Popular Plastics Used In Injection Molding

One of the most famous one for making manufacturing parts is thermoplastic injection molding. In this method, molten material is injected into a mold. But, what are thermoplastics? These are plastic polymers that can be softened by heating and hardened by cooling. 

It is essential to have a clear idea about what type of thermoplastic you want to use to develop parts or products. In this blog, we will tell you about some of the most commonly used thermoplastics injection moldings. Let’s take a look at them.

  • Acrylonitrile Butadiene Styrene (ABS) – This is an opaque thermoplastic and formless polymer. It is composed of three monomers, which are in its name acrylonitrile, butadiene, and styrene. This copolymer is known for making parts, components, and products that are flexible and lightweight. ABS is especially popular in the injection molding process because it can be modified to improve heat and impact resistance as well as toughness.
  • Polycarbonate (PC) – These are plastics that are also formless like ABS but they are transparent. You can use them to make different types of materials. PC is especially preferred for making products that are strong and transparent. The unique thing about polycarbonate is that it can undergo a tremendous level of warping without experiencing any sort of break or cracking.
  • Polypropylene (PP) – PP is known for being one of the most commonly used plastic because of its incredible flexibility. Other properties that make it a widely used plastic in injection molding are high resistance to cracking, high impact strength, high melting points, and high resistance to water, acid, and detergents. It is used to make products such as food containers, utensils, certain apparels, automotive parts, and many other products.
  • Polyethylene – There are two types of polyethylene in the market. High-density polyethylene and low-density polyethylene. Properties such as superior ductility, amazing tensile strength, high resistance to impact, recyclability, etc., make polyethylene one of the most popular plastics in the world. Plastics bags, plastic films, bottles, etc., are made using polyethylene.

Apart from the above-mentioned plastics, some other include high impact polystyrene, polyamide, polystyrene, polyoxymethylene, and thermoplastic polyurethane.
