Clipperlon 2115 USP is a modified PTFE sheet specially designed for high-purity applications such as pharmaceuticals, semicons, food and beverages. The material is free of any pigment, has a natural white color and meets the USP class VI plastics (USP 88), Food & Diary requirements FDA 21 CFR. 1771550 and EC 1935/10/2011 requirements. It is manufactured with bi-axial orientated chains to obtain a tight seal for demanding applications and is produced with hollow glass micro spheres as a filler.​

This material has rather high compressibility characteristics and a low minimum seating stress value. It is therefore highly recommended for low torque applications, plastic pipe systems and flanges, as well as glass and ceramic lined equipment in a wide variety high-purity applications.
