Ftoroplast-42
Ftoroplast -42 (F-42) is one of few dissolvable ftoroplast, is famous for high tenacity, chemical stability to the most aggressive environments, irradiation stability and is proof to atmospheric forcing and low friction coefficient.
Ftoroplast -42 melts in ketone, especially in acetone at plus 20°С, in esters and in dimethylformamide –at plus 50°С; does not melt in spirits, aromatic and chlorinated hydrocarbons.
Specification of F-42 is famous for cross linking with partial or entire is solvability loss under the temperature, exceeding crystallite fusion temperature, and under irradiation
In spite of good dissolve ability in some solvents, F-42 is famous for chemical stability to concentrated acids, alkalis and oxidizers.
F-42 is a crystal in polymer with crystallite fusing temperature plus155-160°С. According to normative documents, the following marks can be produced:

Ftoroplast -42 is famous for resistance to light aging. 200 hour radiation with ABM-4 lamp doesn’t lead to occurrence of carbonyl groups and double linkage in polymer IR spectrum. The thin layer of fluorineplastic-42, applied to coating made of light-fugitive material, protects it from UV-exposure.
Ftorlon film, coatings and varnished cloth are produced of solution F-42 in acetone.
