This work evaluates the technical viability of the use of rice husk ash as filler in polyamide 6 and polyamide 6.6 which are one of the main engineering plastics with applications in several areas. A comparison was made among the mechanical properties of tensile strength, flexural strength, impact strength and the thermal property of glow wire of polyamide 6 and polyamide 6.6 compounds with 30% of rice husk ash and the compounds of these polyamides with 30% of talc. The results of mechanical and thermal properties showed a similar behavior among the polymeric matrices of polyamide with 30% of rice husk ash and 30% of talc. This was verified by the manufacturing of an electric connector injected with polyamide 6.6 with 30% of rice husk ash. Thus, the use of rice husk ash is a viable alternative for the substitution of talc as filler. So, this work contributes for minimizing an environmental problem by enabling the use of rice husk ash in productive processes.
