We are frequently asked what the best plastic injection molding resin to use for specific projects is, and the answer is always the same. And, to be completely honest, there is no single answer to this question. The best resin is the one that is most effective for you and your particular set of circumstances. In this case, the good news is that there are many thousands of plastic ABS Injection Molding resins to choose from, each with properties that are similar but not identical to one another, so you have a wide range of options to consider.

Nylon (PA) is a synthetic fiber.

A collection of nylon quick-release buckles in a variety of colors. The purpose of this demonstration is to demonstrate the durability and versatility of nylon resin. Nylon is frequently used in the manufacture of strong mechanical components such as bushings, gears, and bearings. It is widely used in automotive applications not only because it is tough, but also because Injection Mold helps to reduce weight and production costs when compared to a metal analogue, which is advantageous. You should be aware that, despite the fact that it is a durable plastic, it has a tendency to absorb water. It is not the most appropriate material for marine applications. Nylon is also known by the chemical designation PA (Polyamide), which stands for Polyamide.

Polycarbonate (PC) is a type of plastic.

A collection of polycarbonate CD discs that serve as a decorative accent. In addition to polycarbonate, which is a clear Injection Mold resin with excellent optical properties and is extremely durable, there is also polyethylene. Because of the predictable and uniform mold shrinkage of this amorphous thermoplastic material, precise dimensional control can be maintained when molding with it. When we need something that is significantly stronger than acrylic, we turn to polycarbonate. But keep in mind that if you're making optically clear plastic parts, the mold tool will need to be highly polished, which means you'll need to use a higher grade of stainless steel, which will increase the cost of your project. As you can see, the choice of plastic resin has a significant impact on the selection of the appropriate mold tool material.

Polyoxymethylene (POM) is a type of plastic.

This engineering thermoplastic material is extremely strong, tough, and rigid, making it ideal for use in construction. It is frequently used in the manufacture of gears, fasteners, knife handles, and ball bearings, among other things. The presence of hydrochloric acid and nitric acid in POM should be avoided despite the fact that it has excellent resistance to solvents such as alcohols, gasoline, detergents, and motor oils.

Polypropylene (PP) is a type of plastic.

In the food storage and packaging industry, this thermoplastic  material is widely used because it prevents chemical contamination of the foodstuffs. Polyester (PP) is a thermoplastic that can be washed in hot water without degrading and which has excellent chemical and moisture resistance. The impact strength, elasticity, and toughness of polypropylene are incredible. Designers should also keep in mind that polypropylene (PP) is easy to recycle and that, due to its flexibility, it can be used to create live hinges that can be bent repeatedly without tearing.

Thermoplastic Polyurethane (TPU) is a thermoplastic polyurethane.

As a result, it is frequently used in the manufacture of parts that require the properties of rubber, such as elasticity. You should be aware that TPU is more expensive than other resins, but for many applications, such as protective wire and cable sheaths, there is simply no substitute for this material. Additionally, TPU improves the grip of products that need to be held securely in the hand when they are in use.
