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.

Elastomer Compounds (Rubber)

At TSE, we custom mold and extrude rubber parts utilizing a wide array of rubber including Natural Rubber, Butyl, EPDM, FKM, Fluorosilicone, HNBR, Neoprene, Nitrile, Polybutadiene, Polyurethane, SBR, and Silicone. Using the charts below, you can research the most popular attributes of the material we handle most often.
