CK Type solution vinyl resin is a high molecular weight copolymer of vinyl chloride and vinyl acetate. It is supplied as a powder. CK type solution vinyl resin is normally supplied as a powder. The resin should be stored in dry place in its original closed packaging.Resin has a shelf life of approximately twenty four months when stored at 24℃(75℉) and low humidity. Storage at higher temperatures or conditions of high humidity may result in some product discoloration.resin is mainly applied in binding magnetic card substrates such as telephone card and credit card.
Packing and Storage:
25 Kg /Bag; Craft Paper Bag or PP Knitted Bag lined with plastic film.
550 Kg /Jumbo Bag; PP Knitted Bag lined with plastic film.
Stored in dry place at room temperature,
