K Value is an indicator of molecular weight : K-57 is medium for injection molding,K-67 is medium-high for rigid extrusion, K-70 is higher for plasticized extrusion or calendering. K value relates to other ASTM indicators of molecular weight like Intrinsic Viscosity or Inherent Viscosity.

Is PE-wax used for making PVC Resins?
It's not used for making PVC resin, but it is used in processing it - they use it as a lubricant when making rigid PVC articles like pipe.
What are the materials used for making quality solvent cement for PVC pie joining?
Quality solvent cement for PVC pipe joining typically consists of a blend of polyvinyl chloride (PVC) resin, a solvent such as tetrahydrofuran (THF) or cyclohexanone, and various additives to enhance performance. The PVC resin provides the bonding strength, while the solvent dissolves the resin to create a fluid adhesive. Additional stabilizers and plasticizers may be included to improve flexibility and resistance to environmental factors. This combination ensures a strong, durable bond that effectively joins PVC components.
How do you melt PVC for casting?
Melting PVC can release toxic fumes, so it is not recommended for casting projects. Instead, consider using materials such as resin or wax for casting as they are safer and more suitable for this purpose.
What raw material is PVC made from?
PVC (polyvinyl chloride) is made primarily from two raw materials: ethylene, which is derived from natural gas or petroleum, and chlorine, which is obtained from salt. These raw materials are combined through a chemical process to create PVC resin, which is then processed into a multitude of products.
Is vinyl the same as PVC?
No, vinyl and PVC are not the same. Vinyl is a type of plastic resin, while PVC (polyvinyl chloride) is a synthetic plastic polymer derived from vinyl. Vinyl can refer to a broader range of materials, while PVC specifically refers to a type of vinyl.
What is formula to calculate k value of PVC resin?
The K value of PVC resin is calculated using the Fikentscher K value equation, which is K = (135.5 - 0.31 * log(viscosity)) * (1 - 0.008 * (log(viscosity) - 1)), where viscosity is the intrinsic viscosity of the PVC resin solution. In practice, the viscosity is typically measured using an Ubbelohde viscometer or an Ostwald viscometer. The K value is an important parameter that indicates the average molecular weight of the PVC resin and is used to classify different grades of PVC based on their properties and applications.
What is K in PVC specification?
K-value is a measure of molecular wiight of PVC based on measurements of viscosityof PVC solution.
What is K-value in PVC resin?
K Value is an indicator of molecular weight : K-57 is medium for injection molding,K-67 is medium-high for rigid extrusion, K-70 is higher for plasticized extrusion or calendering. K value relates to other ASTM indicators of molecular weight like Intrinsic Viscosity or Inherent Viscosity.

Why does UPVC not degrade?
UPVC is unplasticised, rigid, PVC. PVC resin must be compounded with various additives to make it a useful product. Heat stabilisers, pigments, lubricants,process aids, impact modifiers and fillers are all added to the raw PVC resin to allow it to be processed into a durable product. If a liquid plasticiser is added to the PVC compound the finished PVC product becomes flexible, ie, no longer rigid.
