Opportunity is calling for smartphone cases and accessories

Average smartphone users reach for their phones up to 150 times each day*—with the potential for hours of device-to-skin exposure. To meet this reality, companies are responding with designs and materials that create durable electronics with extra longevity and sustainable value.

Brand owners also see the opportunity to appeal to consumer’ preference for sustainably-sourced products—in particular, how differentiating products based on sustainability can leverage a growing market and new sources of brand loyalty.

Eastman specialty plastics offer distinctive ways for companies to take advantage of these opportunities.

Eastman Trēva™ engineering bioplastic answers a higher call.

Recent surveys show that consumers prefer purchasing sustainably sourced plastics. In fact,—75% said they would pay more for devices made with sustainable materials.*** Most identified bioplastics as the preferred material.

Trēva is a cellulose-based bioplastic that lets companies offer both high performance and an environmental message. In addition to sharing many of the advantages of Tritan, Trēva provides a combination of properties that is unmatched by other thermoplastics, bioplastics, or cellulosics.

  • Biobased content from sustainably harvested forests
    • Appeals to consumer demand for environmentally friendly products. 
  • Reduced environmental impact
    • Less waste thanks to long life and ESC resistance
    • Excellent flow and durability allow thinner walls.

Trēva is the first engineering bioplastic. Unlike other bioplastics, Trēva also is backed by the technical and electronic market expertise of Eastman.
