ROTATIONAL MOLDING OF LOW VISCOSITY METALLOCENE PP RESINS

摘要

Rotational molding is virtually a shear and pressure free process. The number of materials suitable for rotational molding is limited. This paper gives a summary of a fundamental study on newly developed low viscosity metallocene catalyzed PP resin for rotational molding applications. The influence of viscosity, surface tension and thermal properties on the sintering behavior of the polymers was investigated. Rotational molding experiments were carried out and mechanical properties of the molded parts were characterized.
