It is a braided packing made of pure P.T.F.E. thin yarns fiber which is impregnated piece by piece with P.T. F.E. dispersion, and is treated with a special inert lubricant. It is a very plastic packing Under a minimum pressure of the stuffing box, it keeps unchanged in the long run. The low friction coefficient prevents the surface of the shaft from forming heat even in the presence of high peripheral speeds.
It is suitable for high-concentrated chemical Products, strongly aggressive and oxidative.
