PolyOne Corporation has unveiled the first-ever thermoplastic elastomer (TPE) material able to resist blue jean staining for white and light-colored phone cases.

New Stain-resistant TPEs


Michelle Hearn, global marketing director, Specialty Engineered Materials at PolyOne, said:
“Leading phone case brand owners have been searching for a blue jean stain resistant material that offers expanded design freedom. In addition to a boost in design capabilities, our new stain-resistant TPEs also offer the supply chain flexibility and ease of processing that brands require bringing their white and light-colored phone cases to market both quickly and costing effectively.”

Versaflex™ CE 3320-70 TPE


Using Versaflex™ CE 3320-70 TPE helps brands avoid the sourcing and manufacturing issues of silicone, and it is the only thermoplastic material that stands up to blue jean staining when used in white and light-colored phone cases.

Alternative to Silicone or TPU


Brands using silicone or TPU materials have been seeking an alternative for a number of reasons, including long sourcing lead times and manufacturing challenges for silicone and the inability of TPU to endure blue jeans contact without staining.

Test Methodology


To test the effectiveness of its materials, PolyOne used the same rigorous test methodology used to measure blue jean staining on automotive car seats. Versaflex CE 3320-70 showed no signs of staining, equal to that of the industry benchmark, a branded white silicone case.

Comparison tests using the same methodology that measures blue jean staining on car seats show how new Versaflex™ CE 3320-70 performs versus silicone and TPU

Other Benefits


In addition to blue jean stain resistance, the new Versaflex CE material provides the performance manufacturers expect from a consumer material. It stands up to sunscreen, hand sanitizer and isopropyl alcohol while enduring UV light. This recyclable thermoplastic also processes faster than silicones and adheres well to polycarbonate when overmolded.

This new Versaflex offering can be pre-colored to specifications or used with a PolyOne OnColor™ masterbatch colorant.
