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: When not colored colorless transparent, no ductility, similar glassy materials with similar metal products crisp sound when landing or strike, luster and transparency are better than other common plastic, brittle Hengshui masterbatch silver, easy to break, modified polystyrene is opaque PE: When not colored milky white translucent, waxy, greasy feeling, soft and tough, slightly stretchy, soft low density polyethylene, high density polyethylene hard. PP: When not colored white translucent, waxy, but lighter than polyethylene, transparency is better, harder than the low-density polyethylene. PVC: character yellowish transparent, transparency than polyethylene, polypropylene, polystyrene, inferior, flexible and tough. A domestic polyethylene market analysis, the overall trend of polyethylene market decline this week, according to monitoring, LLDPE fell in the range of 2.67%, a decrease of LDPE at 0.48%, with larger decreases in high-density polyethylene, in the range of 2.28%. Market rebound weakness turned down: Petrochemical quotes come down, stock pressure is acceptable; market transactions in general. Second, the manufacturers of the dynamic this week, the domestic petrochemical manufacturers offer the following tone-based, weekly quotes part petrochemical prices, but week to week following tone-based Sinopec offer Hengshui masterbatch injection, fell in the range 200-300 yuan, Sinopec announced plans to overhaul , after another plant maintenance, supply pressure is acceptable. Third, the market trend this week, falling market polyethylene and polyethylene market down 200 yuan / ton, up and down, linear futures continued to decline, the overall reduction petrochemical prices, market speculation cool atmosphere, turnover is rare weekend PE market price steady decline, most businesses market shipments, some continue to find none other transactions. Downstream demand flat, firm turnover negotiations. LLDPE 7042 mainstream price in 9300-9600 yuan / ton; LDPE 2426H mainstream transaction price in the 9900-10250 yuan / ton; HDPE 5000S mainstream price in 9550-9850 yuan / ton. Fourth, the market outlook forecast Hind, polyethylene unable to continue to rebound this week, the market adjusted downwards, mainly weak downstream demand, obviously unable to continue to hike this week, petrochemicals, but also by the increasing influence of Hengshui masterbatch drawing stock, petrochemical factory price down Hengshui masterbatch, steady market return is expected to maintain the recent market consolidation situation, the ups and downs in the hundred and down.
