Dear Sir,Primary Care Diagnostic is a basically a Medical Diagnostic consumable and tiny products manufacturer, based in south India and we have been sourcing a high molecular weight transparent PS resin, with superior Impact strength, which has a Sp.gravity / density of 1.055 to be used in our diagnostic product, called &＃39;FLOAT&＃39;. Please note that we were also suggested by our consultant to try and use Denka Styrol MW or Starex polystyrene resin, which also has a high molecular weight with superior Impact Strength. We wish to know if you also produce/trade PS resin with high MW and increased impact strength. Our annual consumption would be around 100 bags. We also require samples of your PS resin, so that we could run the raw material to check our exact need and requirement of a suitable resin.If you insist, we are ready to buy 1 or 2 bags initially as a startup, to run and check the compatability. I request you to kindly revert back to us, as we are in need of the PS resin.with best regards,Magesh ParthibanEngineer,BioMedical Services Primary Care DiagnosticsOld No.17/New No.8, Ist street,Sakthi Nagar, Choolaimedu,Chennai, TN,INDIA.Tel: +91 44 6518245Mobile: +91 86088 22481
