First, the appearance of the identification method by observing the appearance of the characteristic of plastic products, such as the shape, transparency, color, luster, hardness, elasticity, etc. to identify their type of plastic. For example (appearance): PS: colorless transparent when not colored masterbatch Cangzhou free hair samples, no ductility, similar glassy materials with similar metal products crisp sound when landing or strike, luster and transparency are better than Other common plastics, brittle, easily broken, modified polystyrene is opaque PE: When not colored milky white translucent, waxy, greasy feeling, soft and tough, slightly stretchy Cangzhou masterbatch, relatively low-density polyethylene soft, hard high density polyethylene. PP: When not colored translucent white masterbatch Cangzhou Toner, waxy, but lighter than polyethylene, transparency is better than low-density polyethylene hard. PVC: character yellowish transparent, transparency than polyethylene, polypropylene, polystyrene, inferior, flexible and tough. Masterbatch market demand customer demand for masterbatch mainly depending on the resin, processing methods and end-use change. For the United States, accounting for polyolefin masterbatch market demand for more than 2/3, PVC masterbatch with demand rising, PET is a small but fast development of resin, because by the environmental restrictions, PET were more inclined to use the fiber before spinning colored masterbatch. Because more and more customers welcome masterbatch masterbatch Cangzhou silver, masterbatch production in the US is expected to be higher than the growth rate of the plastics industry. Plastic masterbatch profits will be greater than other resin masterbatch profit, because plastic masterbatch require high temperature, high-tech, and thus added value is also large. In the long run, China's plastics industry "15" will be the rapid development period, to 2005, China's total to more than 12 million plastic t, need masterbatch 150 000 -24 million t Cangzhou masterbatch free hair Sample | Cangzhou masterbatch | Wong Chun Bird Cangzhou masterbatch can be provided by the Texas Plastic Co., Lyle.
