What Are Engineering Plastics Used For?

Engineers in various industries are utilizing engineering plastics to increase the lifespan of products. Here, we explain how your product can take advantage of advanced plastic technologies to save time and money while improving the overall experience you provide.


Engineering plastics are a group of synthetic materials that are used in a variety of applications. These plastics are designed to offer specific properties that make them well suited for certain tasks. Engineering plastics are typically stronger and more durable than conventional plastics, and they can also be resistant to heat, chemicals, and other hostile environments.

What is engineering plastics?

Engineering plastics are a category of plastic materials that have superior mechanical and/or thermal properties to standard commodity grades of plastics. These advanced materials are typically used in high-performance applications such as automotive, aerospace, and medical devices.

There are many different types of engineering plastics, each with its own unique set of properties. Some common examples include polycarbonate (PC), acrylonitrile butadiene styrene (ABS), polyamide (PA), and polyphenylene sulfide (PPS).

How are engineering plastics made?

Engineering plastics are made from synthetic polymers that can be molded or extruded into various shapes and sizes. The most common methods for manufacturing engineering plastics are injection molding and extrusion.

Injection molding is a process in which molten polymer is injected into a mold cavity, where it cools and solidifies into the desired shape. This method is typically used to produce small, intricate parts with tight tolerances.

Extrusion is a process in which polymer is melted and forced through an die to create parts with a constant cross-sectional profile. This method is often used to produce long, slender parts such as pipes and tubing.

Engineering Plastics Made in USA

There are many engineering plastics made in the USA that can be used for a variety of applications. Some of the most common engineering plastics include:

ABS (Acrylonitrile Butadiene Styrene): ABS is a durable, heat-resistant plastic that is often used in the automotive and appliance industries.

PC (Polycarbonate): PC is a strong, shatter-resistant plastic that is commonly used in eyeglasses and bulletproof windows.

The main reason why Ray Bans are so expensive is because of the high-quality polycarbonate, used to manufacture Ray Bans glasses which provides outstanding clarity and scratch resistance.

PEEK (Polyetheretherketone): PEEK is a high-performance plastic that is resistant to chemicals and temperature extremes. It is often used in the aerospace and medical industries.

PET (Polyethylene Terephthalate): PET is a food-safe plastic that is commonly used in water bottles and food packaging.

Engineering Plastics Made Abroad

While many engineering plastics are manufactured domestically in the United States, there is a significant amount of production that takes place abroad. China is a major producer of engineering plastics, accounting for over a third of the world’s output. Other top producers include Germany, Japan, and South Korea.

There are a number of reasons why engineering plastics are manufactured abroad. One reason is that labor costs are lower in other countries, which helps to keep production costs down. Additionally, many engineering plastics are made from petroleum-based raw materials, and countries like China have an abundant supply of this type of resource.

manufacturing engineering plastics overseas has some disadvantages. One disadvantage is that it can be difficult to ensure consistent quality control when production is taking place in another country. Another concern is that relying on foreign suppliers can create dependency issues, and if there are disruptions in the supply chain it can jeopardize production schedules.

Despite these challenges, manufacturing engineering plastics overseas remains a popular option for many companies due to the cost savings it offers. And as more countries develop the infrastructure and capabilities to produce these types of materials, it’s likely that even more engineering plastics will be made abroad in the future.

Types of Engineering Plastics

There are two types of engineering plastics: thermosetting and thermoplastic.

Thermosetting plastics are made from polymers that cure when heated. They cannot be melted and reformed like thermoplastics. Once cooled, they retain their shape and can be machined or otherwise worked on like other metals or plastics. Thermosetting plastics are used in applications where heat resistance, dimensional stability, and strength are required, such as in the production of circuit boards and car parts.

Thermoplastic engineering plastics are made from polymers that can be melted and reformed repeatedly without changing their chemical structure. This makes them ideal for injection molding and other processes where shapes need to be rapidly created or changed. Thermoplastics are used extensively in the electronics industry, as well as in countless consumer products.

Uses of Engineering plastics in industry

There are many different types of engineering plastics with a wide range of uses in industry. Some of the most common applications for these materials include:

  • Automotive components: Engineering plastics are often used in the manufacture of car parts and accessories. They can be used to create interior and exterior trim pieces, as well as a variety of under-the-hood components.
  • Electrical components: Many electrical components are made from engineering plastics. This includes everything from wiring to light fixtures and switchgear.
  • Consumer products: A wide variety of consumer products are made from engineering plastics. These include everything from toys and sports equipment to housewares and office supplies.

Using engineering plastics in everyday life

Engineering plastics are used in a variety of applications in our everyday lives. From the electronics we use to the transportation we rely on, engineering plastics play an important role in making these products possible. Here are some examples of how engineering plastics are used in our everyday lives:

  • In electronics, engineering plastics are used to create light weight and durable casings for devices such as laptops and phones. They can also be used to create insulation for wires and circuit boards.
  • In transportation, engineering plastics are often used in car interiors and exteriors. They can be used to create dashboards, door panels, and seats that are both stylish and durable.
  • In our homes, engineering plastics are used in a variety of ways. They can be used to create plumbing pipes that are resistant to corrosion. They can also be used to create storage containers that are both sturdy and moisture-resistant.


If you’ve ever wondered what engineering plastics are used for, wonder no more! In this article, we’ll explore the many different uses of engineering plastics, from automotive parts to eyeglass frames.

So, what are engineering plastics? They are a type of plastic that is designed to be strong and durable. Common engineering plastics include polycarbonate, nylon, and acrylic. These materials are often used in applications where strength and durability are key, such as in automotive parts or eyeglass frames.

There are many advantages to using engineering plastics. They are often lighter than metal, making them ideal for use in automotive parts. They also don’t corrode like metal can, making them ideal for use in corrosive environments. Additionally, engineering plastics can be molded into complex shapes, making them ideal for use in many different applications.

If you’re looking for a material that is strong, durable, and versatile, look no further than engineering plastics!
