3 Composites are combinations of at least two materials which is matrix and filler as reinforcement. Natural filler offers many advantages such as low in weight, enhanced biodegradability, and high filling level in composites. Compatibilizer has the ability to react with organic fillers and matrices, forming bridges across the interface.

4 EVA is the copolymer of ethylene and vinyl acetate segments which formed via radical polymerization with different acetate contents. RHDPE is recycled plastic from HDPE which can be used for same application of HDPE with slightly different properties. Taro is an ancient crop that originated in Asia, but is now grown in many parts of the world where it is also known as eddo, dasheen or cocoyam. Taro can be used as potential filler in plastic field.

10 Elongation at Break (%) RHDPE80/EVA20 RHDPE80/EVA20/CL-MAH Filler Loadings (phr)

11 Percentage Mass Swell (%) Taro filler Taro Filler CLMAH Filler Loadings (phr)

12 Increase in filler loading of Taro fillers to RHDPE/EVA/ Taro composites improved tensile strength but reduced elongation at break and mass swell resistance of the composites. Addition of CL-MAH as compatibilizer improved the compatibility and stress transfers of the composites lead to increased in tensile strength and decreased of elongation at break.
