Polymer selection is an important aspect of product design in various industries. It can improve the performance of automotive parts, medical devices, textiles, consumer electronics, and much more. Such a guide is helpful and designed to provide you with the knowledge and tools necessary for choosing polymer for application you require the most.
With an understanding of the unique polymer properties and benefits of various polymers, you can make informed decisions for your specific requirements that will not only fulfill your expectations but also exceed your design requirements.
Step-by-Step Polymer Selection Process
Picking the best polymer for your product can be tricky, but this easy guide will help. A good choice is key to your product’s success. By following these steps, you’ll learn the factors to consider when selecting polymer so you can find the best fit for your needs.
-
Define Your Application Requirements
There are many factors to consider when selecting polymer material for a product. A good understanding of the purpose of the product and how it will be used is crucial to selecting the right polymer. Additionally, the product’s operating environment will need to be considered, including the temperature range it will be exposed to, UV exposure, and the chemicals it will encounter during operation.
It is also important to determine the desired lifespan of the product since that will impact the durability of the polymer to be selected. Careful consideration of these factors allows the selection of the most suitable polymer for your application, with optimal performance and longevity.

Explore Different Polymer Families
The world of polymers can seem vast, but understanding the three main classifications is a great first step. The three main families are thermoplastics, thermosets, and elastomers. Each family offers a distinct range of properties, making them suitable for a wide variety of applications. To go deeper, getting to know what are the types of plastics within these families can help you narrow down your choices and find that ideal polymer for your particular application.
Thermoplastics: These can be melted, shaped, and cooled repeatedly—for instance, PE, PP, PS, PVC, and PET.
Thermosets: These undergo a chemical reaction during processing and become permanently shaped—for instance, epoxy, polyurethane, and silicones.
Elastomers: They have high elasticity and flexibility—for instance, natural rubber, and synthetic rubbers.
-
Assess Properties of the Candidate Polymers:
The task of evaluating a polymer’s properties to ensure that they will match the requirements of your application is a critical element of polymer selection. This entails examining the mechanical properties, which include strength, stiffness, flexibility, impact resistance, and creep resistance. About thermal stability, take into account the polymer’s glass transition temperature, melting point, and heat deflection temperature.
Lastly, environmental resistance is important, thus evaluate the material’s tolerance to the temperature range it would face, UV exposure—which is important for outdoor applications, and compatibility with chemicals it would come in contact with. By considering the factors with due care, you will come up with a polymer that can stand the rigors of the application or use one intends it for.
-
Select Processing Methods
Injection Molding: It is best for high-volume production of complex shapes.
Extrusion: This is good when manufacturing continuous plastic lengths, such as pipes and films.
Blow Molding: This process is used in the manufacture of hollow plastic parts, such as bottles and containers.
Thermoforming: This is used in producing shaped plastic parts from pre-prepared sheets.
Ensure that your chosen polymer will be compatible with the processing method to be used.
-
Look into Regulatory and Safety Requirements
Various industries have strict rules governing polymer selection. For example, medical devices must make use of biocompatible polymers for safety within the human body. The same way, food-grade applications require polymers that are safe for use in food packaging so that they do not leach harmful chemicals into edibles.
Additional standards of flammability and smoke emission may also be enforced, depending on the use case of a product. Polymers used in food packaging also have strict regulations to ensure the food is not contaminated and the consumers are safe.
-
Cost and Budgetary Constraints:
When selecting a polymer for your application, take into consideration upfront material costs and long-term cost implications, such as maintenance and replacement. A good balance is necessary between required performance and cost.
-
Expert Advice and Support
Material selection consultation from polymer material experts is instrumental throughout the material selection process. These experts have a better understanding of various polymers and their properties. Material suppliers offer technical support and guidance; specifically, they will tailor it to your needs and the material selection criteria you have established for your project. They can give you valuable insights through case studies and successful material selection examples in a similar application, showing how these criteria are applied in a real scenario.
-
Test and Prototype
Rather than learning how a polymer should perform, test it to ensure it is ideal for your needs. You may conduct strength tests, impact resistance tests, or find out if it will be able to resist the chemicals in the environment. Making a prototype—an early model of your product—will let you see the actual performance of the material in a real situation. This way, you will find any problems early, instead of after you have made hundreds of final products.
