What is the meaning of K-value in PVC resin?

What is the meaning of K-value in PVC resin?

K-value. A characteristic of the PVC resin which describes the length of the polymer molecules. A measure of the molecular weight of PVC based on measurements of viscosity of a PVC solution. It ranges usually between 35 and 80.

What is PVC 67?

67-01. Reon 67-01 is a medium molecular weight suspension type PVC resin suitable for rigid extrusion products. It is specially recommended for rigid pipes & conduits, rigid profiles, rigid sheets, unplasticised tubular film etc.

What is PVC resin grade?

We are engaged in offering our clients Poly Vinyl Resin (Suspension Grade). PVC Resin is a thermoplastic resin, which in versatility of processing and application surpasses all other thermoplastic materials. We are instrumental in offering qualitative PVC Resin to our valued clients.

What is k67 PVC resin?

PVC Resin Virgin (K -67), commonly abbreviated PVC, is the third-most widely produced polymer, after polyethylene and polypropylene. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows.

What is a K value?

K-value is simply shorthand for thermal conductivity. Thermal conductivity, n: the time rate of steady state heat flow through a unit area of a homogeneous material induced by a unit temperature gradient in a direction perpendicular to that unit area. This definition is really not that complex.

What is K value unit?

K Value is a steady state of the heat flow through a unit area of a homogeneous material induced by the unit temperature gradient. It is used to describe British thermal unit (BTU) per hour. The K Value is independent of the thickness of a substance. It is expressed as watts per meter-Kelvin.

How is PVC resin made?

PVC is produced by polymerization of vinyl chloride monomer (VCM). The PVC is separated off and dried to form a white powder also known as PVC resin (see flow diagram). Emulsion polymerization produces finer resin grades having much smaller particles, which are required by certain applications.

What are the types of PVC?

There are four types of PVC pipes:

  • Unplasticized PVC (PVC-U)
  • Chlorinated PVC (C-PVC)
  • Molecular oriented PVC (PVC-O)
  • High Impact PVC (PVC-Hi)

What is difference between PVC and PVC resin?

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. Other members of the vinyl family can be used for similar applications, but PVC tends to be the most popular member of that family.

What are the different types of PVC resin?

  • PVC Resin. There are 4 types of PVC Resin grouped by polymerization method.
  • Suspension Grade PVC:
  • Emulsion Grade PVC:
  • Bulk Polymerised PVC:
  • Copolymer PVC:
  • K Value.
  • Primary Plasticisers:
  • Secondary Plasticisers:

Are there different grades of PVC?

There are two common types of PVC pipe – schedule 40 PVC and schedule 80 PVC. Schedule 40 PVC is usually white in color and schedule 80 is usually a dark gray (they can also be found in other colors). Their most important difference, though, is in their design. Schedule 80 pipe is designed with a thicker wall.

How is K value calculated?

They can be calculated as 1 / (the sum of the resistances of the various layers of the element (its R-values) + the resistance of the internal and external surfaces of the element).

What is the trade name for PVC K67?

Product: Poly Vinyl Chloride (PVC) Trade Name: PVC K67. PVC K67 is designed to give an easy processing product for extrusion rigid applications since it has moderate melt viscosity with high melt strength.

What kind of resin is Reon 67-01 used for?

Reon 67-01 is a medium molecular weight suspension type PVC resin suitable for rigid extrusion products. It is specially recommended for rigid pipes & conduits, rigid profiles, rigid sheets, unplasticised tubular film etc.

How is PVC K67 used in rigid extrusion?
