Frequently Asked Questions


What is a TPE?

Thermoplastic Elastomers are generally low modulus, flexible materials that can be stretched repeatedly to at least twice their original length at room temperature with an ability to return to their approximate original length when stress is released. The grandfather materials with this property are thermoset rubbers, but many families of injection-moldable thermoplastic elastomers (TPEs) are replacing traditional rubbers. In addition to use in their basic form, TPEs are widely used to modify the properties of rigid thermoplastics, usually improving impact strength. This is quite common for sheet goods and general molding TPEs.


How does shrinkage affect TPEs?            
As TPEs cool from their molten state, the molecules align with each other and shrink the overall size of the molded part. While usually only in the thousandths of an inch per inch range, shrinkage can dramatically affect the molding and removal of the part as well as the appearance of the final part.
If shrinkage is uneven, a part meant to lay flat can bend or warp. Additionally, in applications with tight tolerances, unexpected shrinkage may affect the fit of a part in an assembly.
What are the advantages of TPEs?
TPE materials have the potential to be recyclable since they can be molded, extruded and reused like plastics, but they have typical elastic properties of rubbers which are not recyclable owing to their thermosetting characteristics. TPE also require little or no compounding, with no need to add reinforcing agents, stabilizers or cure systems. Hence, batch-to-batch variations in weighting and metering components are absent, leading to improved consistency in both raw materials and fabricated articles. TPEs can be easily colored by most types of dyes. Besides that, it consumes less energy and closer and more economical control of product quality is possible.

What are the Processings of TPEs?

The two most important manufacturing methods with TPEs are extrusion and injection molding. Compression molding is seldom, if ever, used. Fabrication via injection molding is extremely rapid and highly economical. Both the equipment and methods normally used for the extrusion or injection molding of a conventional thermoplastic are generally suitable for TPEs. TPEs can also be processed by blow molding, thermoforming, and heat welding.
