Abstract

In article ways of combination of thermoflexible polyurethane of brand Vitur TM on the basis of simple polyether with In/6 fluoroelastomers SKF-32 and SKF-264V/6 are considered.

Dependence of technological and physicomechanical properties of compositions of thermoelastoplastics (TEP) on ways of combination of initial components is shown: made one- and two-phasic extrusion molding; with use of curative agents for fluoroelastomers and without them; with different options of introduction of components.

Optimum ways of combination of components thermoflexible polyurethane on the basis of simple polyether with In/6 fluoroelastomers SKF-32 and SKF-264V/6 are defined.

Data, confirmatory are provided that at combination of SKF-32 fluoroelastomer and thermoflexible polyurethane of brand Vitur TM occurs increase of firmness of fluorinated composition of TEP to TS-1 fuel and MS-8p oil.
