The 10 Most Popular Injection Molding Plastic Types


Sometimes, people ask what the best plastic injection resin is for their particular project. In most cases, its not the one that works for everyone. There are many plastic injection molding resins that have the same properties, but with different properties. Injecting plastic resin is a process that produces plastic parts with the same properties. This means that there are many options when it comes to making plastic injection mold components.


Before buying a plastic, make sure that it has the proper function and physical environment in mind. There are a number of factors that you should consider when choosing a plastic material. When it comes to choosing a material for injection molded parts, many factors go into play. Some of these include strength, durability, flexibility, and color. Understanding the properties of plastic injection molding resins can help you narrow down your search.


Nylon (PA)

Nylon quick-release buckles are made from durable resin. These versatile components can be used to produce various mechanical parts. Nylon is very popular in various industries due to its numerous advantages, such as its toughness and low weight. However, it is not ideal for marine applications. Although it has a strong plastic, nylon tends to absorb water. This material is not ideal for marine applications.


Acrylic

These tubes help to demonstrate the various properties of acrylic. It's commonly used to produce transparent components such as windows and lighting equipment. Its transparent and optical properties make it suitable for various artistic purposes. BPA is a harmful organic compound, so plastic injection molding resins like acrylic are considered safe for food storage.


Polycarbonate (PC)

A decorative collection of CD discs made from polycarbonate. This resin is very durable and has excellent optical properties. Amorphous thermoplastics such as polybutene can provide a uniform and predictable mold shrinkage. When used for high-strength applications, polycarbonate can be used. When it comes to making optically clear plastic parts, the mold tool should be polished to a high quality. This means that it should use a more expensive steel material.


Polyoxymethylene (POM)

This image shows a kitchen knife with a handle made using polyoxymethylene (POM). This material is mainly used as a component of the gears and other industrial equipment. It has a very strong and rigid structure. POM shouldn't be exposed to gasoline, diesel, and alcohols. Also, it shouldn't be used to remove nitric acid and hydrochloric acid.


Polystyrene (PS)

There are two main types of polystyrene resins used in injection molded goods. These are High Impact Polystyrene and General Purpose Polystyrene. Both GPPS and HIPS are transparent. Both the transparent and opaque sides of PS are visible, while the high impact part is opaque. Cases for power tools are made with HIPS.It can take a lot of abuse in the field. But that also means it’s not very environmentally friendly.


Acrylonitrile Butadiene Styrene (ABS)

Due to its properties, polypropylene is commonly used in the food packaging industry. It doesn't mix with chemicals and can be washed in hot water. Polyester PP can be washed in hot water without damaging it. It has high chemical resistance and good moisture resistance. PP is also easy to recycle, and it can be used to make various live hinges that can be bent without tearing.


Polyethylene (PE)

A row of four polyethylene trash cans lining a park is commonly used as a template for making plastic resin containers. This material is called PE, and it's a lightweight plastic that has properties that make it more durable. This cheap and easy-to-use plastic cleaner is commonly found in plastic containers. It can be used to remove plastic parts from various products. PE is also the most common injection molding resin for making toys because it’s non-toxic and can take a beating without complaint.


Thermoplastic Polyurethane (TPU)

TPU is a type of flexible plastic that has great tear and tensile strength. It is commonly used to make parts that require elasticity. Although it's more expensive than other resins, TPU is often considered the substitute for many applications. One example is the use of TPU for holding cables and protective wire.


Thermoplastic Rubber (TPR)

Thermoplastic Rubber is a type of resin that's commonly used in the medical industry. This material is very durable and can withstand harsh weather conditions. TPR is a highly resilient plastic that can handle different types of liquids. It is used in various applications due to its properties. This material is commonly used in medical equipment such as catheters and suspension bushings.
