Dissipation of static build-up and dust control.

Astra Product Code Astra Internal Reference Description
A-3450 PE Anti-Oxidant additive Masterbatch
A-3500 PE process Stabilizer additive Masterbatch
A-3550 PE Anti-Static additive Masterbatch

The choice of a correct antistatic is crucial and is determined by a wide range of factors such as polymer type, processing conditions and end application. By careful selection of the correct blend of antistatic ingredients, Astra Polymers has developed a dynamic range of products to cover the whole spectrum of requirements.

Masterbatches can be fast acting to reduce dust attraction in food packaging and display applications and can be formulated to give longer-term effects in demanding applications such as flooring.

Combinations with antiblock and slip products for use in the film industry allow cost effective and high performance to be available for polyethylene and polypropylene film extruders.

Application:-Examples Sheet, Film, Fibres, Injection Moulding and others.

Antistatic Additive Packages

  • Many years experience with antistatic technologies
  • Products for film, fibre, sheet, & mouldings
  • Products tailored for specific performance applications
  • Combination masterbatches for the complete solution

Antistatic Additives

Internal antistatic additives are substances which are added to polymers/plastic articles during thermoforming or compounding in order to minimize the natural tendency of most plastics to accumulate static charge.

Generally these additives work by migrating to the surface of the polymer, usually in a molecular or multi-molecular layer, and attracting water molecules from the atmosphere. The water lowers the surface resistivity from the approximate value of 1014 - 1015 ohms for most polymers (including styrenics and polyolefinics) to 1011- 108 ohms.

The additive molecule normally consists of a hydrophobic part, which confers a level of compatibility with the polymer and a hydrophilic part which attracts the water that forms the surface conductive path. The type of additive used depends on achieving appropriate compatibility with the polymer in question, an appropriate rate of migration, an appropriate persistence of effect and the ability to undergo the manufacturing process, both of the additive concentrate and subsequent conversion into the finished product.

The speed of antistatic effect and its duration can be optimised through careful choice of the additive. The migration rate is determined by a number of factors including the relative compatibility of the additive and the polymer, polymer crystallinity, total additive formulation, concentration of antistat present and temperature.

Classes of Antistatic Additive:-

There are four classes of antistatic additive:

  • Cationic:
  • Anionic:
  • Nonionic:
