Important raw materials for the manufacture of fluorine coating polytetrafluoroethylene (PTFE Tape) by the August 2010 price of 5.6 yuan / tonne in 14 yuan / ton. August 22nd, are the leading manufacturers in China offer fluorocarbon resin over 140,000 yuan / ton. Dongyue Group Ltd initial price of 144,000 yuan / ton, factory prices Zhejiang Juhua Co. of 143 000 yuan / ton, Shanghai 3F New Materials Co., Ltd initial price of 143,000 yuan / ton. Prices of more than 2 times higher than last year.
Involved in trade, chemical industry analyst, said Zhang Li, the PTFE Adhesive Tape is quickly passed an important reason for the tight supply. Although the number of over-capacity of PTFE, but the most important raw material for the manufacture of Teflon tetrafluoroethylene monomer serious shortage of supply, that the production of Teflon. The report shows that in 2010 the worldwide production capacity of approximately 15 million tons of PTFE, the demand for around 100,000 tonnes, the production, but only 90 000 tonnes. March this year, the earthquake in Japan has led to a reduction in overall capacity effectively PTFE 15000-2500000 tonnes.
So why the main raw material for the production of monomers TFE PTFE appear insufficient supply problem? It is understood primarily by two F22 (R22) from the thermal decomposition of tetrafluoroethylene. Second half of 2010, subject to foreign production capacity of R22, the unit lower factors, tetrafluoroethylene R22 no new supply of raw materials. To produce another great use of PTFE pentafluoroethane (R125) R125, the demand for an increased demand for PTFE.
