1301 FLEXIBLE GRAPHITE IMPREGNATED WITH PTFE BRAIDED PACKING
MK1301 is made of industrial grade graphite impregnated with PTFE mixture and inert lubricant.
Compressed asbestos sheet are generally cheap, convenient. But the biggest trouble is the charring of rubber and packing, and the low temperature will result in the loosen of material. and finally cause leakage in the joint part or in the shim itself, and agglo-merating, smoking, and the planking are more easy sticking on the flange. Beside, asbestos will cause heavy pollution. So the high-strengh graphite sheet and non-compressed asbestos sheet will be used instead of asbestos materials.
Modified PTFE is made of PTFE resin with a certain amount of fillers, such as glass fiber, silica, etc., mixed evenly at high speed, molded by molding, and then sintered at high temperature. Has excellent compressibility, recovery and sealing. Its unique properties and high-level characteristics show tightness and torque retention.
