Prayag Polytech [Pvt] Ltd offers Carbon Black Masterbatches. Prayag Polytech [Pvt] Ltd. Is an ISO 9002 company. Carbon Black Masterbatches are used a key additive in many types of plastic resins. Carbon black can impart a variety of desirable characteristics, including color, protection from UV radiation and conductivity. Carbon black is a widely used black pigment because of its coloring ability, cost effectiveness and performance. Simple coloring requires only enough carbon black to achieve opacity at 0.5 %loading. The undertone exhibited by carbon black ranges from warm brown to alcohol blue. Carbon Black Masterbatches with blue undertones are often favored because of their perceived higher jet ness. Tint strength is the relative ability of the carbon black to darken a colored resin. Gloss level can range from a very shiny appearance to a matte finish.
Carbon blacks are composed of spherical partials ranging in diameter from 10 to 100 nm, and in surface area from 25 to 150 m2/g. Surface area, in turn, affect jetness [intensity of black color] and UV resistance of the carbon black. Grater surface area increases both jetness and UV resistance because more surfaces are optically available for absorption of visible & UV light. Carbon Black Masterbatches also act as an ultraviolet light stabilizer. Carbon black masterbatches having higher volatile contents tend to act as free radical scavenger.
