GEHR E-CTFETM (HALAR)

E-CTFE is a linear block copolymer and belongs to the group of amorphous high-performance plastics. It is highly UV and weather resistant and also withstands high-energy (radioactive) radiation. Ethylen-Chlortrifluorethylene exhibits an extraordinary impact strength at temperatures ranging from -104 °F to +302 °F. A great part of the product properties attributes to the very smooth surface and differentiates HALARTM from other fluoropolymers. Due to the fact that E-CTFE is very pure, this material is being used to process chemicals and ultrapure water for the semiconductor industry. Also the permeation resistance to oxygen, carbon dioxide, chlorine gas and hydrochlorid acid is 10 to 100 times better than PTFE.
