Notes:
The usefulness of rotational moulding (rotomoulding) as a polymer processing technique isoften limited by the selection of polymers, which in most cases happens to be polyethylene (PE). Inthe present study, PE polyethylene was blended with wollastonite microfibres and maleatedpolyethylene (as a coupling agent) with the purpose of developing an improved material for rotationalmoulding. The incorporation of wollastonite fibres without any coupling agent improved the tensilestrength, but showed a reduction in impact strength. As expected, the most significant enhancementdue to wollastonite was in the tensile modulus.. The addition of a coupling agent improved both theimpact strength and the processability, especially when wollastonite was coated with aminosilane.Scanning electron microscopy revealed good adhesion between the coated fibre reinforcement and thepolyethylene matrix at the fracture surface
