Leader Clipperlon 2115 usp

Description

Modified PTFE gasket material manufactured with bi- axial orientated chains to obtain a tight seal for demanding applications. This material has a rather high compressibility characteristics and low minimum seating stress value. Therefore this material is highly recommended for low torque applications, plastic pipe systems and flanges, as well as glass and ceramic lined equipment. White in color and produced with Modified PTFE and hollow glass micro spheres as a filler. Special developed for pharma applications.

Product Data Sheet

Application

Specially developed for high purity applications like Pharmaceutical, Semicon, Food and special bevarage. Optimal in applications with low bolt loaded constructions for sealing applications across whole pH-range: Therefore extremely suitable for glass, ceramics, and plastic lined or distorted flanges and even flanges with light surfaceirregularities. The material is USP class VI plastics (USP 88) listed and meets Food & Diary requirements FDA 21 CFR. 177.1550 and EC 1935/10/2011.

Chemical Compatiblity

Particularly for use with strong acids (except hydrofluoric acid) and alkalis. Other applications include solvents, fuels, water and oil. A chemical resistance list is available upon request. Pressure up to 800 psi Temperature from -410 °F up to 500 °F

Delivery Options

Flange gaskets and sheets are available in thickness of 1/32",1/16", 1/8", 0,5mm, 1mm, 1,5mm, 2mm and 3mm. Other thicknesses available on request.. Standard gaskets can be supplied in accordance with ASME B16.21, EN12560-1 as well as EN1514-1. Non-standard or special gaskets can be manufactured according to customer drawings, or by given sizes or Edrawing.

Temperature

Particularly for use with strong acids (except hydrofluoric acid) and alkalis. Other applications include solvents, fuels, water and oil. A chemical resistance list is available upon request. Pressure up to 800 psi Temperature from -410 °F up to 500 °F
