How To Choose The Right Plastic Materials?

Choosing the right plastics for the project begins by defining your application’s functional, mechanical, thermal, chemical, and environmental requirements. These needs help determine whether an amorphous plastic or a semi-crystalline plastic is most suitable. Once the plastic family is selected, the specific materials such as polypropylene, polyethylene, PVC, or polycarbonate can be matched to the application. The final choice should ensure reliable performance under expected loads, temperatures, and exposure conditions.

Main Factors To Consider

When choosing plastic materials consider these main factors in order to find the right materials for each application.

Confirm the chemicals being used in the application will be compatible with plastics being considered. Different plastics have different reactions to different chemicals.

Will the plastics be exposed to the outdoors? If so, consider factors such as UV resistance, resistance to temperature changes, and weathering.

Determine the stress on the plastics during the application. Ensure the plastics being used meet the impact, pressure, and load resistances needed.

Take into account the temperature range of the applications and confirm that the plastics being used are compatible with that range.

Consider the industry regulations were the plastics will be used. If the application is being used within industries involved with food, water, medical, agriculture, etc. ensure the plastics are safe for use in those industries.

Consider if the plastics will needed to be bent, threaded, welded, or glued and ensure the plastics being used are capable of those processes. 

Additional Factors To Consider

Use these additional factors to ensure the plastic materials being used are the optimal choice for the application.

Appearance

Different plastics come in different colours and transparencies. Take into consideration if the application has appearance requirements and ensure the plastics being used meet those.

Cleaning

Consider if cleaning or sterilization processes are needed in the application and make sure the plastics being used are compatible with those methods.

Thickness

Plastic materials are available to come in many different thicknesses. Determine if the application will require thinner materials for lighter weight and flexibility, or thicker materials for more strength and rigidity.

Weight & Density

If there are weight or space requirements in the application take into consideration the weight and density of the plastics. Different plastics have different weights and densities for the same amount of material.
