Material Choices

Choosing a material is not an easy task, but most often the selections can be pared down to a handful of candidates that will work with your project. After that, the final option may have to be determined with testing. TSE Industries offers a number of material options in the areas of Engineered Polymers (Plastics) and Elastomer Compounds (Rubber). Based on the industry served and end-use, several options may be of interest to you. The material choices below will provide you with a brief overview of the product attributes. 

At any time, our staff are happy to discuss the various options with you. Contact us today to start the conversation!

Note: Property data shown are typical average values and will vary based on specific production lots and by size and product configuration. They should be used only as a guide to primary selection for the application of a given material and never for purchase specifications. All values shown are based on bone dry specimens.
