Expert advice: For PVC paste resins, what properties of the material do the K value, viscosity number, apparent bulk density, moisture content, pH value of water extracts, residue on sieves, and viscosity respectively represent?
For specific details, one should consult relevant books for accuracy. Minutes of the PVC Paste Resin Seminar: The meeting concluded that the domestic paste resin market currently features the following characteristics: 1. Prices of paste resin in China are currently at low levels. Recently, key raw materials such as calcium carbide, VCM, EDC, and ethylene have all seen price increases, placing significant cost pressure on manufacturers, who as a result operate at losses ; 2. The plant load of domestic manufacturers is generally low, with the average industry operation rate remaining at around 70-80%. Some companies’ newly expanded plants already have the capacity to produce, but due to the weak market conditions, they have not started operations yet ; 3. The inventory levels of resin paste manufacturers are at low levels; although some manufacturers have higher inventory levels, there are maintenance plans scheduled for an extended period ahead, so there is little pressure on their inventory levels ; 4. Affected by the financial crisis, demand in downstream sectors remains weak; in particular, the utilization rates in the artificial leather and automotive leather industries are low. The toy, wallpaper, and glove industries are in relatively better condition, but they are heavily impacted by competition from foreign suppliers ; 5. The downstream industry faces significant difficulties, with export-oriented enterprises being the most severely affected. However, as the price of raw materials used in production has remained low for some time now, the downstream industry is generally operating at break-even or with only slight profits. In light of the current characteristics of the paste resin market, the participants reached the following consensus through thorough discussions: 1. Manufacturers should control production levels appropriately, maintain stable operating capacities, and ensure a balance between supply and demand in the domestic market ; 2. All manufacturing enterprises should strengthen communication and coordination in their operations, avoid unnecessary price competition, and safeguard their own interests ; 3. Domestic enterprises should carry out technological upgrades and increase investment in research and development, in order to break the monopoly of imported sources on certain grades of paste resins ; 4. Actively explore international markets, take advantage of the increase in export tax rebates, boost export efforts, and gain a foothold in those markets.
What books? It’s better to be more detailed
There’s a book on PVC processing technology on the forum; you can download it to take a look. I don’t have enough money to do that
There’s a book on the forum titled \"Polyvinyl Chloride Paste Resins and Their Processing Applications\"; you can download it and take a look – it covers everything related to the topic
