Uses of Lead Stearate in PVC. Lead stearate is formed from the reaction of lead and stearic acid. It has a melting point of 105-112 掳C and a boiling point of 359.4 掳C. The compound is commonly used as a stabilizer in PVC production. It also lubricates plasticized PVC compounds, specifically in covering PVC cables to help minimize electrical

Internal and External Lubricants are two types of lubricants used in PVC applications. They serve the process of reducing friction. However, both of these category of. lubricants act differently and have distinct functions. There are certain lubricants such. as Stearic Acid that act as both external and internal lubricants.

only one that is used to any extent as a lubricant for rPVC is stearic acid. The most common stearic acid used is the so-called 'triple pressed' grade, which is a blend of palmitic (carbon chain length of 16) and stearic (chain length of 18) acids. It is a good external lubricant with a balance of some internal lubricating properties.

External lubricants reduce the adhesion between PVC and metal surfaces. They are mostly non-polar such as paraffin and polyethylene waxes. The external lubrication effect is largely determined by the length of the hydrocarbon chain, its branching and its functional group. At high dosages they can lead to cloudiness and exudation.

weight acids have a greater affinity to PVC. Stearic acid is the one mostly used because of its low price and its availability. Commercial materials used as lubricants usually contain from 40to 97%stearic acid and the rest is made of palmitic, myristic, and oleic acids. Example

scatter light. In some cases, e.g. with stearic acid, the particles of the excluded lubricant are seen under the microscope to have the form of dendritic crystals. The chemical structure of the lubricant is both the prime factor in its compatibility with PVC and the link between compatibility and the mode of lubricant action.

Synthesized by Nature. Natural waxes and esters are an extremely diverse range of materials that can be used to lubricate rigid PVC. Natural waxes are synthesized by many plants and animals. Rheogistics offers fatty acids, fatty acid esters, and natural waxes suitable for use in rigid PVC. Product Name.
FAQ
- QIs stearic acid a lubricant for rigid poly(vinyl chloride)?ACalcium stearate–stearic acid as lubricants for rigid poly (vinyl chloride) (PVC). Capillary rheometer measurements and extrusion properties Capillary rheometer measurements show that stearic acid can be characterized as a normal lubricant. If the content of stearic acid is increased in rigid PVC formulations, the melt viscosity will decrease.
- QIs stearic acid a normal lubricant?ACapillary rheometer measurements show that stearic acid can be characterized as a normal lubricant. If the content of stearic acid is increased in rigid PVC formulations, the melt viscosity will decrease. This leads to a corresponding increase of shear rate and volumetric flow rate.
- QWhat is your main market?ASouth-east Asia, South-America, Middle-East, CIS Countries
- QWhat are internal lubricants used for PVC processing?AInternal lubricants used for PVC processing reduce mutual attraction between the PVC’s molecular chains and promote the flow between the molecule via chain slippage. They are also known as processing aids or melt flow enhancers.
- QWhat fatty acids are used to lubricate RPVC?AAlthough a large number of fatty acids are commercially available, the only one that is used to any extent as a lubricant for rPVC is stearic acid. The most common stearic acid used is the so-called 'triple pressed' grade, which is a blend of palmitic (carbon chain length of 16) and stearic (chain length of 18) acids.
- QWhich lubricant is used in rigid profile extrusion?APolyethylene waxes or oxidized polyethylene waxes with an acid number of approximately 10-20 are most commonly used. Oxidized polyethylene waxes are used in rigid profile extrusion at levels of 0.1-0.2 phr. 2. Fatty acids, which act mainly as external lubricants. The higher-molecular weight acids have a greater affinity to PVC.
- QWhy is lubricant important in PVC processing?AIn PVC processing, the role of lubricants as an additive is indispensable. Lubricants internally improve the flow characteristics of the PVC melt during processing and externally reduce friction between the PVC melt and the metal surfaces of the processing equipment.
