  • Optical brightener concentrates

  • Optical brighteners are compound that fluoresce under UV light, reemitting in the blue region of the spectrum. Optical brightener masterbatches are used to produce materials that require ”extra whiteness”. the…

  • Clarifying and nucleating agent

  • Some thermoplastic polymers crystallize on cooling where as others don’t. crystallization takes place during cooling in the mould, with the formation of microscopic-ordered regions called spherulites. Clarifiers improve the optical…

  • Flame retardants and smoke suppressants

  • There are two ways to reduce polymer flammability. A few polymers (mostly thermosetting) can have their synthesis modified by replacing part of the starting materials chemically reactive halogenated analogues. In…

  • Antiblock Masterbatch

  • Antiblocking agents are used in the packaging film industry to stop film from sticking to itself during processing, when in use, or during storage on rolls or shipped in cartons.…

  • Antioxidants

  • Most synthetic polymers are fairly stable for long periods provided that they are (a) not heated and (b) kept away from light. But they can be attacked very slowly by…

  • Antistatic masterbatches

  • Plastics are mostly electrical insulators. The development of a static charge on two plastic film surfaces during mutual contact occurs by the transfer of electrons from one film surface to…

  • Fillers

  • Particulate fillers such as calcium carbonate, carbon black, silica, talc and chopped cottonwere originally used in the early plastics as cost-cutting additives because their cost by weight was lower than…

  • Process aid masterbatches

  • Process aids are added in small quantities to minimize defects in finished products and to improve processing characteristics. Some lubricants and impact modifiers also have beneficial effects on processing. The…

  • Slip agents

  • Most polyolefin exhibit a degree of thickness and hence can’t be readily processed into packaging films without the presence of additives to ease their ability to separate and slide. Slip…

  • UV light stabilizer

  • Most products are exposed to sunlight or fluorescent lighting at some time during service. Light can promote degradation, sometimes involving oxygen. Prolonged exposure to oxygen and light especially with a…
