  • Beta(β)-PP(PPH) Main properties

    Beta(β)-PP(PPH) BE60-7032 is a high molecular weigth low melt flow rate polypropylene homopolymer,which through the β modification,with delicate crystal structure.It even has excellent low tempertature impact strength.Increased hydrostatic strength,enhanced chemical resistance,increased temoertature,and its coefficient of expansion down to the lowest point of the same material. Beta(β)-PP(PPH) BE60-7032 is a Northern European chemical industry and for production of ultrapure pipes,fittings,extrsion,sheet and other developed grades.
