Due to this unique viscosity/shear rate dependency, normal melt index testing (done at shear rates as low as 50 1/sec) will not reflect how the TPE will process at higher shear rates. Shear rates during extrusion processing are usually in the hundreds of reciprocal seconds and shear rates during injection molding may go as high as 11,000 1/sec. TPE FAQs

GLS™ TPE MAJOR HOME APPLIANCE SOLUTIONS ENHANCE APPLIANCE PERFORMANCE WITH TPEs FOR ANTI-VIBRATION FEET In the highly competitive home appliance market, brands are driving to differentiate products with enhanced performance attributes. GLS TPEs are designed to help you stand out from your competitors with reduced appliance movement and noise. Anti-vibration feet made with our TPEs have resistance to wear and tear, better performance and function, improved processability and reduced number of part defects.

™ TPEs vs. One caveat: Typical TPE shrinkage is around 2% while that of substrate materials is closer to 1%. When looking to incorporate sustainable content into your TPE, the raw material cost may be more expensive than traditional materials for three reasons 1) supply chain maturity, 2) high demand, low supply, 3) location of source and supplier.

Known for offering tight seals and reducing vibration and noise, certain thermoplastic elastomers (TPEs), like OnFlex™ grades, may be better suited for your particular application than the historically incumbent materials, like general purpose TPEs, thermoplastic vulcanizates (TPV), and thermoplastic polyolefins (TPO).
