Each type of additive masterbatch has some special properties to improve the end plastic product.

ANTI STATIC ADDITIVE

Prevention of dust & sparking

PLAST ANTISTAT MB-014PE,012PP prevents spontaneous discharge of static charges accumulated on polymer surfaces by lowering the surface resistivity of the material.

Mechanism

Problems caused by static electricity charge will be reduced or eliminated & atmospheric dust pick up is prevented to get best clarity and surface finish in polymers. Typical applications include Electronics, Food & Pharma packaging, Medical drapes and gowns , Light-sensitive products, etc.

Significance of Antistat

Anti-static agents are added to polymers to provide static protection by lowering the resistivity of the material. Different anti-static additives can be used, depending on the level of static protection needed and how long the anti-static effect needs to last.
read more Antistatic masterbatches are based on fatty acid ester type of anti static agents to neutralize the charges on the surface of the polymer. By using anti static additives, problems caused by static electricity charge will be reduced or eliminated. Commonly occurring problems are: -Dust pick up which can ruin clarity and surface finish.

Additional Features

When the unprotected plastic is brought into contact with another material, loosely bound electrons pass across the interface. When these materials are then separated, one surface has an excess charge, while the other has a deficiency of electrons.

How it works ?

Anti-static agents are added to polymers to provide static protection by lowering the resistivity of the material. Different anti-static additives can be used, depending on the level of static protection needed and how long the anti-static effect needs to last. Most plastic materials are electrical insulators and have the ability to support high static build up.

Additional Features

Anti-stats are added to plastics to reduce or eliminate a static build up. Anti-static additives work by lowering resistivity and are capable of neutralizing the surrounding static field. Antistatic agents can be composed of different types of chemicals: ester, amino, amide, and polymeric fatty acids,etc. Static charge separation is caused by the movement of one material over another which can result in issues

Additional Features

The role of an antistatic agent is to make the surface or the material itself slightly conductive, either by being conductive itself, or by absorbing moisture from the air. The molecules of an antistatic agent have both hydrophilic and hydrophobic areas. While the hydrophobic side interacts with the surface of the material, the hydrophilic side interacts with the air moisture and binds the water molecules.

Key features of Bajaj Anti Stat

Protection from Moisture

Antistatic Additives control the buildup of static charges in thermoplastic parts, enabling them to dissipate by absorbing and ionizing moisture from the air, which forms a conductive path for surface static charges.

External

External antistatic additives are topical agents applied to the surface. For topical antistatic additives, washing the surface completely removes the external antistatic additive , requiring reapplication. The duration of the antistatic action of this type of compounds is very short, due to their abrasion under the influence of mechanical factors.

Internal

Internal Antistatic additives are generally migratory additives and can be inert in nature. After 24-48 hours from the extrusion process, they migrate to the surface of the material, forming a hygroscopic film that attracts water. The created layer has a conductive function, as it discharges static electricity and reduces the level of plastic charge. The antistatic effect in the case of internal antistatic agents is long-lasting .

Less Moisture

Upon migrating to the surface, antistatic additives interact with atmospheric moisture, forming a microscopic layer of water on the substrate surface. This layer of water is held in place by hydrogen bonds. As the relative humidity changes, so does the water layer on the substrate surface. At low humidity, less moisture is available to form hydrogen bonds with the antistatic additives than is available at higher humidity.

Long Lasting

Permanent anti static agent agents are usually based on polymers and therefore have high molecular weight. During processing, they form a network within the polymer matrix that requires anti static property. It starts functioning immediately and does not require depending upon migration to surface. This also helps to retain anti static property over a long time.

Applications

Applications of Antistatic additives includes Injection moulded items for high precision applications in Electronics, Automotive , Films used as liners for Bulk pharma, Blow moulded articles for Chemicals, Pharma, food and Water tanks also.
