By virtue of their insulating nature, polymers of all types allow static charge to build up on their surfaces, particularly in the case of films and fibers, with their large surface-area-to-volume ratio.
Such static charge build-up may lead to undesirable consequences in the final product. For instance, built-up static charge can attract dust onto a food package, which is undesirable aesthetically. At times, static charge can damage circuit boards in electronics packaging and may cause hazardous conditions such as fire or explosion in the vicinity of flammable materials.
Azodicarbonamide as a Nucleating Agent
Everyone is well aware of the use of exothermic foaming agents to reduce the density of plastic parts and lower cost by using less resin. Exothermic foaming agents are also used to eliminate splay marks in injection-molded parts, and to improve electrical properties in wire and cable insulation. Even those who utilize physical blowing methods often use exothermic foam concentrates, such as azodicarbonamide, (ADC) as nucleating agents.

Learn how slip masterbatches are used in the films business and about their properties that allow them to provide effective performance.
Stabilizing Polyolefins Against the Influences of Weather
Polyolefins for outdoor use must be stabilized against the degradative effects of “Mother Nature.” Ultraviolet (UV) light, moisture, oxygen, and heat can all impact polymer longevity. Proper stabilization is critical when the polyolefin product is expected to provide durability over months or years of service.
Over the years, torque rheometry has proven itself a valuable tool for studying multi-component thermoplastic systems, to assess processing behavior. Torque rheometry measures the viscosity-related torque generated by the resistance of a material to the shearing action of the plasticating process. Typical analyses include the study of processing behavior, influence of additives, thermal sensitivity, shear sensitivity, compounding behavior, and others. Torque rheometry is therefore an excellent tool in helping to determine the most process-stable formulation (resin, color concentrate, and additives) for your process. It is often used successfully in troubleshooting unwanted degradation and gel formation problems. Examine, in some depth, how this technique works, and how it can be used for your production needs.
