GENERAL DESCRIPTION
TecaPro ® MT Heat Stabilized Polypropylene sheet provides all of the outstanding properties found in standard polypropylene, but has been subjected to a special heat-stabilizing process. As a result, TecaPro ® MT is able to withstand higher service temperatures with less water absorption than standard polypropylene.
The enhanced properties of TecaPro ® MT make this material an excellent candidate for replacement of PBT, Acetal, PTFE, PPO and a number of other high-performance plastics. Recommended sterilization techniques include steam autoclaving and cold sterilization.
TecaPro ® MT is available in white and black colored sheets only. Contact us for size availability.
