PHB has interesting features such as biodegradability, sustainability and durability.However, it has a high cost, in addition to being hard, brittle and thermally unstable during processing.Therefore, it was found convenient to study the crystallization of PHB/20% babassu compounds, with the intention of reducing the cost of the composite, in addition to seeking improvements in thermal properties.In this work, the parameters of nightstick twm-850xl melt crystallization were studied for PHB/20% babassu compounds driven at different cooling rates under a nitrogen flow.Subsequently, crystallization parameters were compared for different cooling rates.

A kinetic analysis of data obtained for melt crystallization was performed.Among the models studied, Pseudo-Avrami showed the best correlation with experimental data, with discrepancy between +6% and -4%.The Mo model presented a discrepancy between +15% and elbeco adu ripstop pants -8%.A modified Mo model discrepancies are reduced to +3% and -4% within the range of validity of the model.
