Hiils sold it's PB-know how early 1970's. Mobil Chemical Co. and Witco Chemical Corp. worked on PB in the USA before SHELL took over the PB-plant. Since then SHELL improved Polybutylene significantly and supplied major companies in USA and Europe with new grades of PB especially formulated for underfloor - heating and radiator connections.
