Antistatic Masterbatch - Based on Stearate type antistatic agent - Offers the possibility of avoiding electrostatic charging by causing a fast discharge of the plastic's surface - Ha.. RM . Additives that render plastic compounds antistatic or electrically and/or thermally conductive are in hot demand. The wider acceptance of such compounds in replacing metal (particularly aluminum) and non-conductive plastics is evident in their double-digit annual growth rates over the last decade.
anti-static additive ato replacement additives compatibilizers natural fibers for wood like effect, also non ferrous metals when packed in films containing this additive prevents growth of bacteria and fungus on any polymer surface- based on organic biocide. According to author and consultant Ed Crutchley the book covers well over different innovations. Raw materials covered include: color or reflectivity change materials and additives; effect and other special color materials; films, foils and labels; inks, paints, coatings; and substrate polymer resins, blends and additives.
Anti-static powder: EP series: This product is a powder antistatic product. Applicable to all kinds of antistatic coating and all antistatic products, market coverage in the domestic leading position, and bulk exports to the overseas market. Conductive Agents/ Anti-static Agents: EL series: This product is a liquid antistatic product. In general, addition of fibers improves the mechanical properties of plastics like tensile strength, elasticity and heat stability. Carbon and metallic fibers are known to offer antistatic and conductive properties to the plastic. Fibrous additives can .

Inorganic Anti-static Agents Inorganic salts and some basic organic elements can be incorporated into the polymer matrix to suppress long term use static accumulation. Examples include: Carbon that is used in carpet fibers to produce antistatic flooring; Carbon used in many non-woven wipe applications for clean rooms and aerospace applications.
Internal antistatic agents include insoluble, migratory additives that, after a brief period, bloom on the plastic part’s surface, where they are effective. These molecules have a partially hydrophilic structure which attracts a film of surface water that lowers the resistivity of the.
Since antistats are surface active, they compete with other surface active additives such as slips in film applications.
These additives do not react chemically with each other, but rather, can compete with each other for occupation of the substrate surface. Amine and amide antistats are basic in nature.
They can react with acidic additives. An antistatic agent is a compound used for treatment of materials or their surfaces in order to reduce or eliminate buildup of static charge and moldings book be generated by the triboelectric effect or by a non-contact process using a high voltage power source.
Static charge may be introduced on a surface as part of an in-mold label printing process. No matter which manufacturing process you use, from bi-oriented film extrusion to injection molding, we can support you with additives that will improve your efficiency. Our solutions include slip and antiblock agents, processing aids, cycle time reducers, multi-purge agents, and various other process enhancers that help your operations run at.
Unlike many other antistatic technologies, Pebax ® antistatic polymers are permanent and non-migratory. They form an immediate, continuous non-fugitive 3D network within the host polymer structure.
The result is an antistatic blend that may be colored (unlike Carbon black solutions) and is largely independent of relative ambient humidity. By using an antistatic agent, problems such as dust pick up, handling difficulties and electrical discharge will be reduced or eliminated.
Specialty additives ADK STAB ASE. Evonik’s extensive range of additives to improve performance in fire resistance, melt flow or anti-scratch behaviour. You can also experience process-ing additives for cost optimization potential in your own production processes.
Converters from the film, packaging, foam or Avoid water molding industry can fulfill their needs for antistatic. Antistatic Additive MICRO AS PE Extrusion, blown film, cast film, injection molding Proprietary blend of antistats for both short and long term performance MICRO AS 10 PE Extrusion, blown film, injection molding GMS antistat for short term properties in PP, LLDPE & LDPE films.
FDA at all levels MICRO AS PE Injection molding, blow. KC is an anti-static agent. It significantly improves the power charge and make the power ascending rate higher, enhances hardness of coating film. Since the first edition of this book was published, there have been wide-ranging developments, covering chemistry and formulation of new and more efficient additive systems and the safer use of additives, both by processors in the factory and, in the wider field, as they affect the general public.
Surface modification of polymers using plasma technology is an effective and environmentally friendly method to ensure appropriate antibacterial treatment. In a multi-step process of surface. Einar ® is based on a polyglycerol ester with a customized fatty acid chain length distribution, matching the specific needs of antistatic polyethylene food packaging applications: migratory properties even in high density PE, highest efficiency in binding water vapor molecules to form a conductive surface layer at lowest surface.
The modification of the surface energy of textile fibers to improve functional properties such as the wettability was reviewed. This modification can be achieved by physical or chemical methods or by the combination of both.
Applications of plasma treatment to improve the wettability of natural and synthetic fibers were considered and some methods of wettability measurement were mentioned.
According to Toyota Tsusho, the additives help users realize top-notch transparency and a smooth surface appearance on their films.
The material has seen use in, for example, packaging for powdered pharmaceutical products, and meets European regulations limiting migration of antistatic agents from a host film/package. The additives and contaminants which occur in textile fibers vary widely, depending on the type of fiber and the pretreatment which it has received.
Synthetic fibers such as nylon and polyester contain trace amounts of contaminants such as catalysts and catalyst deactivators which remain after the synthesis of the basic polymers.
Typical Conductive Additives RTP Company has years of experience modifying nearly 60 engineering thermoplastics using various levels of additives, including: powdered carbon black, carbon fiber, metal fiber, metal-coated carbon fiber, and metal powder, to produce a unique compound for your application.
Product overview "Additives for Masterbatcher, Compounder and Converter" This overview includes our product portfolio of additives for masterbatchers, compounders and converters. We offer a broad range of products such as colorants, adjuvants for surface treatment as well as specialty additives for miscellaneous applications.
Our antistatic/ESD additives impart certain conductivity in host materials so that they can release static electricity effectively in a controlled way and thus prevent problems caused by static electricity and uncontrolled electro static discharges, such as electric shocks, destruction of electronic circuits, sparks, appliance malfunctions.
Antistatic agents can be added to polymers to minimize the natural tendency of most plastics to accumulate static charges. Antistatics are based mainly based on migratory additive systems, which can give fast and long term stable antistatic properties.
Migratory additives rely upon the presence of atmospheric humidity to give optimum performance. The GLS™ Injection Molding Guide provides in-depth information on part design, mold design and processing for styrenic block copolymer (SBC) thermoplastic elastomers (TPEs).

Corona treatment: The treatment of a film surface with corona discharge results in oxidation or ‘burning’ of the surface layer of the film. Such corona treatment usually accelerates the migration of the antistats to that side, by increasing the concentration gradient and also by making that surface .
