The growing demand for plastic materials implies an evolution constant technological change in composition and treatment.

For accompany this evolution, lubricants incorporate sets of additives to improve their physicochemical properties.

Sometimes there may be an interaction between lubricants and plastics or elastomers, due to the polarity of the materials and the tendency to exchange of material between them (migration / dissemination).

The negative effects of these phenomena can be, among others: volume of plastic material because of the penetration of lubricant into its structure and, consequently, an increase in the volume of plastic or the elastomer, softening the polymer, which causes a drop in its structural rigidity or embrittlement, which can result in cracks on the surface.

This is why it is important to check in advance the compatibility of the lubricant with plastic or elastomeric materials in the environment close.
