PVC sheet performance
General performance PVC resin is a white or light yellow powder with a relative density of 1.35-1.45. The hardness of the product can be adjusted by adding a plasticizer.Mechanical properties PVC has high hardness and mechanical properties. And increases with the increase of molecular weight, but decreases with the increase of temperature. Rigid PVC has good...Read more -
pvc sheet
The natural color of polyvinyl chloride (PVC) is yellowish translucent and shiny. Transparency is better than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard polyvinyl chloride. Soft products are flexible and tough, and feel sticky. The hardness of hard products is higher ...Read more -
What kind of plastic is pvc?
PVC is a multi-component plastic that can be molded and processed in a variety of ways, with a wide variety of products and a wide range of uses. Through the best combination of resin and additives to meet the molding processing and use conditions, the ideal product can be obtained. To do this, it is necessary to understand the type of PVC, processing charac...Read more -
pvc introduction
What material is pvc? PVC resin has the advantages of good chemical stability, high mechanical properties, excellent electrical insulation, flame-retardant and self-extinguishing, and low price. However, it also has poor thermal stability, low use temperature, high brittleness of hard products, and low cold resistance. The shortcoming of easy aging under the...Read more -
In-depth study of the current situation of polyoxygenated adhesives for PVC materials in China
The molecule of PVC flocking glue contains the characteristic urethane polar bond (one NHC00 one), and also contains many ester bonds, ether bonds, urea bonds and so on. It has good bonding properties to a variety of materials. He Yicai described the synthesis of a one-component solvent-based polyurethane adhesive for PVC decorative film-metal plate. It uses...Read more -
PVC resin
PVC resin is a white or light yellow powder. This resin cannot be used directly, but must be modified by adding various modifiers to prepare various products. According to different product uses, different modifiers can be added to show different physical and mechanical properties. Adding an appropriate amount of plasticizer to the polyvinyl chloride resin c...Read more -
cpvc manufacturer
The engineer of the cpvc manufacturer said: CPVC resin is made by modifying PVC resin isopropyl titanate, which is a new type of rubber product. CPVC resin powder is white or light yellow powder. After PVC resin undergoes isopropyl titanate, the irregularity of molecular bonds is improved, the optical rotation is improved, the solubility of the resin is expa...Read more -
cpvc pipe
cpvc pipes are often used in the transportation of sewage and chemical corrosive liquid media. The price of the raw material cpvc is higher due to its high cost, resulting in higher prices for cpvc pipes. Some processing plants will use pvc pipes instead, so can pvc really replace cpvc pipe manufacturers?The editor must first tell you all purchasers that if ...Read more -
pvc material processing and molding polyvinyl chloride
The molding process of polyvinyl chloride pipes needs to start with pvc materials. First, the material formula can be divided into soft polyvinyl chloride and rigid polyvinyl chloride according to the different usage amounts of stabilizers, plasticizers, and lubricants. High-quality polyvinyl chloride is also called UPVC or RPVC, and soft polyvinyl chloride ...Read more -
