Calcium carbide method PVC resin analysis
Calcium carbide method PVC resin analysis,
ethylene method PVC resin, PVC CFR prices, PVC manufacturers, PVC market, PVC quotation,
This week PVC maintenance enterprises are still more, less new maintenance enterprises. The overall reduction of PVC enterprises is higher. The start of PRODUCTION of PVC manufacturers decreased by 1.01% month-on-month to 76.40% and 7.43% year-on-year. Calcium carbide method increased by 0.08%, in 78.30%; The ethylene method decreased 5.08% to 69.92%. The northwest region saw a month-on-month decline of 1.91% to 84.29%.
Social inventories continue to increase Despite the current decline in operating rates, social inventories continue to increase due to weak demand. The social inventory of the latest PVC market was 339,100 tons, with a sequential increase of 0.91% and a year-on-year increase of 114.62%; In east China, the monthly increase was 2.63% to 275,100 tons, while in South China, the monthly decrease was 5.88% to 64,000 tons.
The domestic downstream starts to maintain a low level. According to the statistics bureau, from January to May, the development investment of real estate enterprises, the area of new construction, and the area of land purchase all showed a decline of different magnitude; From January to May 2022, the investment in infrastructure construction increased by 6.70% year-on-year, but the demand for PVC industry has not been fully implemented. The finished products of enterprises are facing sales pressure. In terms of raw materials, we maintain the rhythm of receiving orders at low prices and replenishing inventory at low prices. Product inventory: maintain a partial position, some enterprises due to the difficulty of product sales promotion.
In export markets, CFR China prices hit their lowest since January 2021, with expectations for further downward revisions in New Asian quotes in July. India’s monsoon season is expected to last until September as domestic demand weakens and businesses are cautious about imports. PVC quotation in Asia in July is expected to continue to decline month-on-month, and is expected to drop around $100 / ton.
Overall, PVC cost end support is weak; The late maintenance of the supply side will be reduced, and the start of construction will be improved. The turning point of social inventory has not yet appeared. Demand side, domestic and external demand double off-season, downstream to maintain the main demand for procurement. PVC will continue to weak shock, rebound is limited, PVC market is expected to continue to run weak shock in the short term.
PVC is an acronym for polyvinyl chloride. A resin is a material often used in the production of plastics and rubbers. PVC resin is a white powder commonly used to produce thermoplastics. It is a synthetic material widely used in the world today. Polyvinyl chloride resin has outstanding characteristics such as abundant raw materials, mature manufacturing technology, low price, and wide range of uses. It is easy to process and can be processed by molding, laminating, injection molding, extrusion, calendering, blow molding and other methods. With good physical and chemical properties, it is widely used in industry, construction, agriculture, daily life, packaging, electricity, public utilities, and other fields. PVC resins generally have high chemical resistance. It is very strong and resistant to water and abrasion. Polyvinyl chloride resin (PVC) can be processed into various plastic products. PVC is a lightweight, inexpensive, and environmentally friendly plastics. Pvc Resin can be used in pipes, window frames, hoses, leathers, wire cables, shoes and other general purpose soft products, profiles, fittings, panels, injection, moulding, sandals, hard tube and decorative materials, bottles, sheets, calendaring, rigid injection and mouldings, etc. and other components.
Features
PVC is one of the most widely used thermoplastic resins. It can be used to make products with high hardness and strength, such as pipes and fittings, profiled doors, windows and packaging sheets. It can also make soft products, such as films, sheets, electrical wires and cables, floorboards and synthetic leather, by addition of plasticizers
