Gịnị bụ polchlorotrifluethylene (PCTFE)?

PCTFE bụ polymer na ajị ahịrị nke na-emegharị nkeji nke polymerization nke vinyl trifluoride.

PcTFE bụ polymer kristal na-agbaze gburugburu 217 Celsius C na njupụta nke 2.13 g / cm3. PcTFE bụ ihe na-arụ ọrụ kemịkal na ụlọ dị iche iche, ebe enwere ike ịlele ya site na mpekere ole na ole wee zachaa ya site na ụfọdụ sochiri ụkwụ dị n'elu 212 Celsius. PCTFE nwere ikike mgbochi gas gas.
