A Comprehensive Guide to Buying Thermoset Plastics

Your Guide to buying the best thermoset plastics

Overview

Thermoset plastics are a type of polymer material which has become increasingly popular for a variety of applications. The unique properties of thermoset plastics make them ideal for use in a wide range of industries, including automotive, aerospace, and construction. This buying guide provides an overview of the different types of thermoset plastics available on the market today, as well as the key considerations to keep in mind when selecting the best material for your project. With the help of this guide, you’ll be able to make an informed decision when selecting the right thermoset plastic for your needs.

Key features

Availability - Thermoset plastics are available in a variety of shapes, sizes, and colors, which makes them suitable for a variety of applications.
Durability - Thermoset plastics are highly durable and resistant to most chemicals, making them great for long-term use.
Cost - Thermoset plastics are relatively inexpensive when compared to other plastics, making them a great choice for a variety of projects.
Ease of Use - Thermoset plastics are easy to work with and contain fewer components than other types of plastics, making them a great option for beginners.
Environmental Impact - Thermoset plastics are generally considered to be more environmentally-friendly than other types of plastics, as they are made from non-renewable materials.
Recyclability - Thermoset plastics are not typically recyclable, so it is important to consider the long-term impact when using them.

Important considerations

Pros

Durability: Thermoset plastics are extremely durable and can withstand high temperatures, making them ideal for products that require long-term performance.
Chemical Resistance: Thermoset plastics are highly resistant to chemical solvents and corrosive substances, making them ideal for applications involving harsh environments.
Lightweight: Thermoset plastics are lightweight and easy to work with, making them ideal for projects requiring portability and easy assembly.
Cost-Effective: Thermoset plastics are typically more cost-effective than other types of plastic, making them ideal for applications requiring a low-cost material.
High Strength: Thermoset plastics are extremely strong and can often be used in place of metal or wood, making them ideal for applications requiring a strong material.

Cons

Cost: In general, thermoset plastics are more expensive than thermoplastics.
Difficult to Recycle: Thermoset plastics cannot be melted and re-shaped and are, therefore, not easily recycled.
Difficult to Repair: Because of their chemical bonds, thermoset plastics cannot be easily repaired when they break or fail.
Heat Sensitivity: Thermoset plastics tend to be more heat sensitive than thermoplastics so they can become weak or brittle when exposed to high temperatures.

Common questions

What is a thermoset plastic?
Thermoset plastics are a type of polymer material that, once cured, will not melt or soften when exposed to temperatures. This makes them more heat resistant than thermoplastics, which are able to be re-melted and reshaped.
What are the advantages of using a thermoset plastic?
The main advantages of using thermoset plastics are their heat resistance, strength, durability, and chemical resistance. They also do not absorb moisture easily, making them ideal for applications where water resistance is important.
What are the disadvantages of using a thermoset plastic?
The main disadvantage of using thermoset plastics is that they are difficult to work with, as they cannot be reshaped or remolded once cured. Additionally, they are more expensive than thermoplastics.
What applications are best suited to thermoset plastics?
Thermoset plastics are best suited for applications that require high heat resistance, chemical resistance, and/or water resistance. Common applications include aerospace components, electrical insulation, and automotive components.
What properties should buyers consider when purchasing thermoset plastics?
Buyers should consider the properties of the thermoset plastic they are looking to purchase, including its heat resistance, strength, chemical resistance, and water resistance. It is also important to consider the cost, as thermoset plastics are usually more expensive than thermoplastics.

Trivia

A funny fact about thermoset plastics is that they are used to make a type of LEGO block called KEVA planks. KEVA planks are unique in that they are made from single pieces of thermoset plastic that interlock together to create structures without the need of glue. This allows children and adults alike to build complex and intricate structures without the mess of glue or extra pieces. They are also great for STEM activities because they offer the opportunity to build complex structures without having to use a lot of pieces. Sources: kevaplanks.com
