Hello Andy Thank you for your mail, I regret I have no interest in chemicals. However, I have a serious interest in synthetic rubber, to replace the natural rubber in current use in the manufacture of shoes. If you can offer the finished synthetic rubber, I would be very pleased to hear from you again with specification details and whether you can supply small samples. With best wishes.
