PVC Paste Grade
PVC Paste Resin is the type of PVC resin used in the production of a variety of PVC products. These include construction materials such as roofing, walls, and flooring.
PVC paste resin is a versatile material that can be processed into different forms and used in various applications. It is also resistant to moisture and temperature change, making it ideal for many industries.
Grades of PVC Resins
PVC resin is a highly versatile thermoplastic and can be used in a variety of applications. It is often used in flexible, non-food packaging, roofing membranes, imitation leather, signage, and a wide range of inflatable products. It also has many desirable attributes, including durability, nonflammability, resistance to chemicals and oil, and mechanical stability.
Depending on the application, PVC can be used in either rigid (unplasticized) or plasticized form. Rigid PVC is typically used for pipes and fittings, while plasticized forms are used in various other applications, such as bottles, credit cards, and wire and cable insulation.
Aside from its versatility, PVC is also a good choice for applications that require high strength and impact resistance. These include pipes and fittings for the transportation of drinking water, sewage, and underground drainage.
There are a number of different grades of PVC resins, each with varying properties. These grades are based on their K-value, which is an indicator of the molecular weight and degree of polymerization.
*K70-75 are the highest K value resins and give the best mechanical properties but they are also more difficult to process. They need more plasticizer for the same softness, and are therefore more expensive.
They are also more sensitive to heat and need higher levels of stabilizer to prevent thermal degradation. Stabilizers are also used to help protect the material from moisture and humidity.
Lubricants are additives that help to keep the hot PVC from sticking to metal surfaces during processing. They can be made from a variety of compounds, including stearic acid and waxes.
These lubricants are vital to the performance of the compound, as they can help prevent melts from slipping on the extruder screw or forming a sticky layer on processing surfaces. They can also help to minimize the formation of air bubbles and ensure that the final product is smooth, glossy, and durable.
There are a number of different additives that can be added to PVC resin, including plasticizers and pigments. These can be dissolved in the resin, or they can be formulated into a dry blend, or powder-mix. In addition, there are special acrylic polymers that can reduce the viscosity of the resin during processing, and impact modifiers that can improve the strength of PVC pipe.
Low K Value Resins
PVC paste grade is used for Plastisols and this type of resin is produced by spray drying an Emulsion of a Finely Powdered PVC in Water. This requires much more energy to produce and is considerably costlier than Suspension Resins.
The emulsifying chemicals and catalysts are conveyed with the PVC in the spray dried Emulsion, which reduces the purity of the finished PVC. It is also considerably more difficult to obtain the desired Electrical properties and Precision from this type of resin. The Clarity of PVC Paste Grade plastisols is much poorer than Suspension and Bulk Polymerised pvc and a number of other types of PVC.
Unlike Suspension Resins, Paste Grades do not adsorb much Plasticiser at room temperature. They need a high temperature in excess of 160 to 180 degrees to plasticer into the resin throughout preserving it, and they require more heat than Suspension Resins.
In addition to the emulsifying agents, paste grade resins often contain blending lubricants. These lubricants prevent the hot PVC from sticking to metal surfaces during processing, which is important for production efficiency. Many lubricants are available, including Stearic Acid, Waxes and complex esters, but the correct choice is crucial for the final product.
As well as lubricants, paste grade resins often have additives such as rust inhibitors or flame retardants. These can be useful in preventing damage to equipment, reducing waste and increasing efficiency.
Other additives can also be used to increase strength, dimensional stability, and coloration. These can include titanium dioxide, iron oxide pigments and carbon black.
Another additive can be an abrasive agent, such as Ground Calcium Carbonate. This abrasive filler can cause scratches and damage to the extruder and Injection Moulding machines, which would be impossible with Suspension Resins.
Besides these, paste grade resins can have other added compounds to make them more flexible and more durable. These can include silicone additives, acrylates, urethanes, polyamides and other chemicals.
The demand for PVC paste resins is expected to rise owing to the increasing popularity of PVC-based products in developing countries, especially Asia Pacific. Additionally, the rise in infrastructure development activities is also driving the market. In addition, the increasing demand for vinyl sheet and synthetic leathers is supporting the growth of the global PVC paste resin market.
Medium K Value Resins
The PVC paste grade is a type of polyvinyl chloride (PVC) resin that is used for various applications, including printing inks, molding, automotive sealant, industrial gloves, adhesive, PVC flooring, synthetic leather, wall coverings, and others. It can be manufactured by using either the emulsion or micro-suspension method. It is a cost-effective and lightweight product that offers superior properties compared to other xinjiang zhongtai products.
The global market for paste PVC resin is expected to expand at a CAGR of 5.63% between 2019 and 2027, owing to the rising demand for affordable construction materials and fast urbanization in Asia Pacific. Furthermore, the increasing inclination toward modernizing households and the growing demand for vinyl flooring are also projected to boost the global PVC paste resin market during the forecast period.
Medium K value resins are the most commonly used PVC resins due to their high degree of mechanical properties and processibility. These resins are primarily used for PVC foam and sheet applications, as well as general purpose products. They have a high level of flexibility and can be shaped to different shapes.
This family of PVC resins contains several different grades, all with a similar chemical composition and mechanical properties. The most popular resins are the K65-68 range, which are ideal for UPVC (unplasticised or rigid PVC) applications and plasticised applications. They have a good balance of mechanical properties and processibility, which makes them the most versatile of all PVC resins.
These PVC resins can be processed with a number of different extrusion systems and are available in both rolled and flexible form. They have excellent clarity, color, plasticizer absorption and thermal stability.
Another advantage of this PVC resin is its tackiness and elasticity, which ensures that the material can be molded and shaped easily. It can also be sprayed and dyed to produce different colors.
The optimum processing of this PVC resin is achieved by using the micro-suspension polymerization method. This is a highly efficient and reliable manufacturing process that allows the PVC to be prepared in small volumes with minimal waste.
