However, since direct importation is not possible for us, we request you to let us have the name and contact address (phone no.) of your dealer or agent in India ( Mumbai) or Bombay as it was earlier known. Besides the above we are very keen to have Nucleating Agent for improving the clarity of P.P.Homopolymer to as close as possible to Random P.P. |
