Study of the Mechanical Properties of Polyphenylene Sulfide Films

The mechanical properties of the films of various compositions based on polyphenylene sulfide (PPS) were studied. To obtain the films by extrusion, the PPS powder was subjected to heat treatment for 0/20/60 min. The compositions containing 3% of a plasticizer were also prepared. Each of the film types was tested in two forms: amorphous and crystallized. The crystallized films were obtained by holding the amorphous samples at the temperatures above the cold crystallization temperature. The mechanical properties were studied by conducting tensile tests of the standard film samples.
