Semi-free-flow modified PTFE.

TFM X 1630 PTFE is a semi-free-flowing modified PTFE for compression molding, said to combine the mechanical, thermal and electrical properties of TFM PTFE with improved processability, as compared to standard-flow PTFE. TFM X 1630 PTFE is engineered with an average particle size of 200 microns and a bulk density of 840 g/l. It is said to be ideal for molding processes that require low pressures and easier mold filling, and for applications that demand smooth, high-quality surfaces and excellent dimensional stability, according to the company. TFM X 1630 PTFE is said to be used in a variety of challenging molding and process applications, particularly thin-walled isostatic moldings and large sheets and billets. The results are said to be high quality end products like valve linings, valve seats, internal pump components, chemical distribution manifolds, gaskets, lined pipe, sheet linings for vessels and other chemical processing equipment. TFM PTFE is said to have the same excellent temperature and chemical resistance as unmodified PTFE. However, it does offer some significant advantages, according to the company, including reduced cold flow and low permeation. (Dyneon)
