We only offer fully refined Paraffin Wax grades which are white in colour, odourless and of straight chain hydrocarbons C20-C40. The melting point of paraffin wax is the main property that enables its engineering latent heat and thermal energy storage applications. Our editors will review what you’ve submitted and determine whether to revise the article. Paraffin Wax is a traditional, multi-purpose, oil-derived wax that can be offered in a wide range of melting points to meet customer requirements. In silver vases, melted paraffin is used as a fastener, for, unlike clay, it will not tarnish the container and can be removed easily with hot water. It is soluble in ether, benzene and certain esters, but does not dissolve in water. The wax may finally be blended together to give certain desired properties such as melt point and penetration. Is paraffin wax bad for you? A fully refined paraffin for use in packaging and candles. Without even realizing it, you may be burning paraffin throughout your home while exposing yourself to the health hazards associated with it. They mainly used for manufacturing candles, board, plastics, rubber and other fields. Our wax range available in melting point from 54°C to 64°C and with slab & granule form; Paraffin Wax offers excellent protection and water barrier properties making it ideal for coating cardboard and paper especially for the food industry. Expired - Lifetime Application number US34726A Inventor Jr James M Page Paraffin wax was first produced commercially in 1867, less than 10 years after the first petroleum well was drilled. It’s a white, waxy or jelly-like substance that comes in many forms. This refers to the temperature the wax needs to reach before it starts melting. Paraffin wax, colorless or white, somewhat translucent, hard wax composed of saturated hydrocarbons ,with a melting point in the range of about 48° to 66°C (120° to 150°F). The heat of the wax is absorbed by the skin and thus opens the pores. In wood and paper matches, it helps to ignite the matchstick by supplying an easily vaporized hydrocarbon fuel. Calwax 127 Parafin Wax. Paraffin represented a major advance in the candlemaking industry because it burned cleanly and reliably and was cheaper to manufacture than any other candle fuel. Table 9.1 shows the paraffin wax properties including the values of wax density, melting point, flash point, and autoignition temperature. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) for paraffin wax fume exposure of 2 mg/m3 over an 8-hour workday. It assists in extracting perfumes from flowers, forms a base for medical ointments, and supplies a waterproof coating for wood. You might have also seen … Paraffin wax, colourless or white, somewhat translucent, hard wax consisting of a mixture of solid straight-chain hydrocarbons ranging in melting point from about 48° to 66° C (120° to 150° F).

BW 407. It is sold with various melt points, typically between 43-60 °C (other melting points are available on request) and has a boiling point above 370 °C. [9] It is insoluble in water, but soluble in ether, benzene, and certain esters. Paraffin wax is soluble in benzene, ligroin, warm alcohol, chloroform, turpentine, carbon disulfide, and olive oil. Download scientific diagram Heating and Cooling Curve of Paraffin Wax from. Paraffin wax is combustible and has good dielectric properties. [11] This is better than nearly all other materials except some plastics (notably Teflon). Paraffin wax is solid at room temperature and begins to melt above approximately 58C Flash point of paraffin wax is about 250 c.Common applications of paraffin wax are candle making, cosmetics, food industry, lubrication, electrical insulation .Paraffin wax has different grades based on 2 main characteristics: oil content and melting pointLight or heavy paraffin wax with different oil contents. 261 paraffin wax melting point products are offered for sale by suppliers on Alibaba.com, of which testing equipment accounts for 1%. In industrial applications, it is often useful to modify the crystal properties of the paraffin wax, typically by adding branching to the existing carbon backbone chain.
