Abstract EN

We observed the anti-UV action of beetroot extract in an ultra-high molecular weight (UHMWPE) matrix.

The beetroot extract and the one prepared from annatto seed also acted efficiently as pigment to the same polymeric matrix.

Neat UHMWPE and UHMWPE compounded with annatto and beet extract were compression molded and tensile specimens were obtained from the molded plates and submitted to UV radiation for up to 42 days.

Tensile tests were performed and it was observed that the beet extract had a stabilizing action in the polymer compared to neat polymer and the one with annatto extract.

Complementary analyses showed good homogenization of the extracts through the polymer matrix indicating the possibility of use as pigment, although the annatto extract appeared to be very unstable under irradiation.

Spectroscopic characterization helped to explain the stability of the extracts before and after molding.
