Space charge accumulation in polypropylene/elastomer blends with different elastomer types

Space charge accumulation in polypropylene/elastomer blends with different elastomer types

Polypropylene (PP) blended with elastomer has been considered to be a tentative replacement of crosslinked polyethylene (XLPE) as a new DC cable insulation material for its excellent dielectric properties, good resistance to heat and chemical erosion, and especially as a type of thermoplastic material which can be recycled when it goes to the end of its lifetime. However, influence of the elastomer on the electrical performance of the blends is still not fully understood. In this work, polyolefin elastomer (POE) and propylene-based elastomer (PBE) have been added into isotactic polypropylene (i-PP) to estimate the effect of elastomer on the space charge behavior in the blends. It was found that space charge accumulation under 18 kV/mm was weak in virgin PP. With the increase of the elastomer content, the charge injection was encouraged especially in PP/PBE blends. It is proposed that the space charge accumulation is dependent upon the compatibility between the base material and the elastomer, where remarkable homocharge injection would occur in the blends with bad compatibility.

Abstract

Polypropylene (PP) blended with elastomer has been considered to be a tentative replacement of crosslinked polyethylene (XLPE) as a new DC cable insulation material for its excellent dielectric properties, good resistance to heat and chemical erosion, and especially as a type of thermoplastic material which can be recycled when it goes to the end of its lifetime. However, influence of the elastomer on the electrical performance of the blends is still not fully understood. In this work, polyolefin elastomer (POE) and propylene-based elastomer (PBE) have been added into isotactic polypropylene (i-PP) to estimate the effect of elastomer on the space charge behavior in the blends. It was found that space charge accumulation under 18 kV/mm was weak in virgin PP. With the increase of the elastomer content, the charge injection was encouraged especially in PP/PBE blends. It is proposed that the space charge accumulation is dependent upon the compatibility between the base material and the elastomer, where remarkable homocharge injection would occur in the blends with bad compatibility.
