Most Common Manufactured Automotive Plastics

In today’s world of technology, plastic is a necessity that we can’t do without it. As such, there are so many different types of plastics made for different purposes.

Plastic types for use in automobiles are no different. Manufactured automotive plastics are specially created for vehicles to make sure that we’re safe as we traverse the roads.

But what are these plastics, exactly? And what do they do? We’ll go into all the specifics below. 

Keep on reading to find out!


Polypropylene is one of the most commonly manufactured automotive plastics on the market today. It is both lightweight and durable, which makes it ideal for applications where weight is a major factor.

It is also highly resistant to moisture, oils and common chemicals and can withstand temperatures ranging from -60°C to +120°C. Additionally, it is virtually unbreakable and has the ability to be formed and molded into many shapes and sizes to fit the desired application or purpose.

Acrylonitrile Butadiene Styrene

Acrylonitrile Butadiene Styrene (ABS) plastic is one of the most common thermoplastic materials used in the manufacture of automotive parts.

ABS is a more cost-effective and stronger alternative to aluminum and other metals commonly used in automotive parts. Due to its relatively low cost, ABS is used for both exterior and interior parts, such as body panels, dashboards, bumpers, and foot pedals.

ABS has superior temperature resistance and impact resistance, making it an ideal material for car parts.


Polyester is one of the most commonly manufactured automotive plastics that also need automotive injection molders. It’s strong, durable, lightweight and easy to mold, making it an ideal choice for a range of car parts.

Polyester is often used for interior and exterior parts, as it is resistant to heat and abrasion. 

Additionally, it is chemically resistant due to its cross-linked molecular structure, making it a great choice for parts that come into contact with oils, lubricants and other chemicals. 


Composites are one of the most common manufactured automotive plastics. This type of plastic is usually made up of several materials that are fused together to create a material with higher strength, increased flexibility and improved durability.

As such, it is the perfect choice for automotive applications as it is able to resist wear and tear, and can resist heat as well. 

Thanks to their versatile characteristics, composites have become the go-to choice for the automotive industry. They are used in almost all auto parts, from the body to the mechanical components, helping to create safer and more reliable vehicles.

Thermoplastic Elastomers

Thermoplastic elastomers are also one of the most commonly manufactured plastics in the automotive industry. They are cost-effective, lightweight, and provide excellent resistance to extreme temperatures and environmental conditions.

This makes them an ideal choice for components in vehicles such as interior trim, hoses and seals, instrument panel parts and panels, mirrors, door seals and even tires.

A Guide to Knowing Manufactured Automotive Plastics

As a result of reading this guide, you should have a greater understanding of the many varieties, uses, and benefits of automotive plastics.

Knowing these features of the material can help you choose the engine parts and auto body parts that are right for you. Be sure to contact your mechanic for further advice.
