A study of weathering of polyamide-6 under stress

الملخص EN

A method is presented by which polymeric films are exposed to outdoor aging under simultaneous action of mechanical stress and the effect of direct contact between the sample and different solid materials during the exposure can be evaluated.

The results of stress-strain tests for polyam؛de-6 films after two months exposure suggest that upon aging anisometric flaws develop in the material.

The severity of the flaws is affected by the presence and type of the solid material supporting the film.

In the case of a steel support, the flaw formation is accompanied by distinct plastification.
