Described are polymer compositions that include a blend of recycled poly(ethylene terephthalate) (rPET) and a copolyester based on monomers that include on terephthalic acid (TPA), ethylene glycol (EG) and 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD), wherein the blend has improved engineering properties compared to the rPET material.

Blends of copolyesters having recycled content and high heat resistance

Provided is an optically clear protective cover plate for Human Machine Interface (HMI) touch panel displays wherein the cover plate is formed from a thermoplastic polymer comprising a high melt flow polycarbonate. The polycarbonate is characterized by a melt flow rate (MFR), or melt flow index (MFI), of between about 60 and about 80 g/10 min (ASTM D-1238, 300° C./1.2 kg).

HMI display covers having low birefringence

A shaped article comprising a polymer-based resin derived from cellulose, wherein the polymer-based resin has an HDT of at least 95&#xb0; C., a bio-derived content of at least 20 wt %, a notched izod impact strength of greater than 80 J/m and at least one of the following properties chosen from: flexural modulus of greater than 1900 MPa; a spiral flow length or at least 3.0 cm; a flex creep deflection of less than 12 mm; a transmission of at least 70%; a &#x394;E value of less than 25; or an L* color of at least 85.
