HM426 is manufactured from modified high-modulus PTFE film coated with high temperature silicone adhesive. The PTFE film is subjected to a special process that lowers its elongation and increases its breaking strength for easier handling. One side has a silicone pressure sensitive adhesive and the other side offers low coefficient of friction PTFE film, which is thin and conformable. PTFE backing offers excellent high temperature resistance and is chemically inert. This tape construction is weather resistant, stable and non-toxic.
Applications: It is often used as masking during metal bonding, roll covering on plastic extruders, and for fine wire harnesses industry in their repair shops as well as in other markets where thermal spraying is used.
