Shell Expands Sales Of Corterra PTT Polymers

Shell Chemicals, Houston, has
introduced its Corterra PTT polymers to engineering thermoplastic producers globally.

“Corterra polymer is a viable replacement as well as a valuable choice, for new developments
in ETP applications where PBT and PET would be candidates, including molded and extruded goods in
the automotive and electrical/electronics market,” said Barry Cristea, Corterra Polymers business

Shell has worked with several companies on market validation. These companies include Lati
Industria Termoplastici SpA, Italy; LNP Engineering Plastics Inc., Exton, Pa.; and RTP Co.,
Winona., Minn.

According to Kevin Marshall, market manager, RTP Co., Corterra has a promising future in
this market. “After conducting a battery of evaluations, through which we routinely put PRT and
other polymers, we found compounds based on Corterra polymers displayed better tensile and
structural strength than PBT and displayed lower moisture absorption than PBT and nylon.”
