Anti-static Polymers and Plastic Resins
Polymers and plastic resins are compounds consisting of repeating subunits of organic and synthetic base molecules. There exist different types of polymers and plastic resins in use today, and they are typically classified based on their features. The anti-static polymer and plastic resins remain one of the most commonly used polymers for sensitive applications.
Static charges easily build up in polymers and plastics due to the triboelectric effect. Anti-static materials are engineered to reduce or eliminate the buildup of static electricity. Polymers and plastic resins filled or coated with ant-static agents are called anti-static polymers and plastic resins. These agents make the polymers suppress initial charges, provide a slow rate of decay of static charge and enhance electrical conductivity. Anti-static agents include surfactant coatings, metals or conducting additives added to the polymer.
Polymers and plastic resins consisting of anti-static additives have several advantages over polymers with metals or surfactant coatings. Finished parts are lightweight and easier to handle and are also less expensive to fabricate since there is an absence of secondary processes common in surfactant coatings. These plastics dissipate electricity better than insulators but less than conductors.
Selection Criteria
- Surface resistivity: This is the ratio of DC voltage drop per unit length to the surface current per width when an electric current is flowing across the anti-static plastic surface. Surface resistivity is expressed in ohms per square (Ω/sq), and it typically ranges between 10 10 and 10 12 Ω/sq.
- Dielectric constant: Describes the measure of a material’s ability to insulate charges. It is the relative permittivity of a material compared to free space.
- Dielectric strength: Describes the electrical strength of the insulating material. It is the maximum electric field that the polymer and plastic resin can withstand under ideal conditions before it becomes electrically conductive.
- Use temperature: Denotes the operating temperature for which the material was designed to operate.
Applications
Anti-static polymers and plastic resins are generally used in components that are sensitive to static electricity. Typical examples include electronic and computer components. These polymers are also used to line containers that store flammable or volatile substances, such as industrial paints.
