PRE-ELEC® Electrically Conductive and Static Dissipative Compounds

Carbon black has established its position as the most widely used electrically conductive filler, offering a superior price-performance ratio and stable properties over time. Typically, carbon black compounds’ surface resistance ranges between 10² Ω (100 ohms) and 10⁵ Ω (100 kohms). Due to the nature of carbon black, reaching dissipative surface resistance levels above 10⁵ Ω is challenging. However, Premix has successfully overcome this with special resistance control technology, offering static dissipative PRE-ELEC® compounds between 10⁵ Ω and 10⁸ Ω.

Boost Your Business with Electrically Conductive Concentrates

Carbon black concentrates are an excellent way to reduce raw material costs. In PRE-ELEC® concentrates, the carbon black content is optimised to the highest possible level. For maximum cost efficiency, recycled plastics or regrind from your own process can be used for dilution. This small yet innovative step can lead to significant cost savings. Besides the economic advantages, concentrates also allow the modification of product properties. Reinforced plastic can be used for dilution to impart stiffness and strength to the finished product. Flame retardant properties can also be modified by including a flame retardant masterbatch in the process.

PRE-ELEC® ESD Inherently Dissipative Polymer Compounds

Inherently dissipative polymers (IDP) are intended for applications where translucency, cleanliness, and non-sloughing properties are essential. Unlike traditional migrating antistatic compounds, PRE-ELEC® ESD compounds and masterbatches deliver permanent surface resistance levels from 10⁸ Ω to 10¹² Ω, and their functionality is not dependent on humidity levels.

Fibre Compounds for High Stiffness and Non-Marking Products

When applications require high rigidity and/or non-marking material, carbon fibre is the solution. The glass-fibre-carbon black combination is also a cost-effective way to improve product stiffness.

PREMIX PRE-ELEC® Compounds

PREMIX PRE-ELEC® compounds offer low surface resistivity combined with excellent mechanical properties and easy processability. These compounds are typically used in technical parts or containers that come into contact with sensitive electronic components requiring protection against electrostatic discharge (ESD). Additionally, materials with low surface resistivity help protect against static sparking in explosive environments, prevent static charge in sensitive measuring devices, and reduce dust attraction in clean rooms.
