CHEZACARB®

Conductive Carbon Black for Polymer Compounds

Typical market segments represent extruded profiles, pipes, sheets, blown films and injection moulded parts. CHEZACARB® AC is not classified as hazardous (dangerous) according to Regulation (EC) No 1272/2008 (CLP). Information regarding risk management (occupational safety and health and storage) is available in the Announcement according to Art. 32 of the Regulation (EC) No 1907/2006 (REACH)www.unipetrolrpa.cz/en/OurProducts/Pages/Safety_sheets.aspx

Electrical and mechanical properties of the final products are determined by CHEZACARB® AC concentration, polymer type, processing technology and to a lower extent also by additives influencing quality of carbon black dispersion.

Percolation curves – the dependence of the volume resistivity on the carbon black concentration - represent first indications for choosing the appropriate dosage of carbon black to obtain required compound conductivity.

CHEZACARB® AC is used in a wide range of plastics to obtain permanently antistatic, dissipative or electro-conductive materials. It is determined to impact:

Electrical conductivity to plastics, rubber and paints

Electromagnetic properties to plastics, rubber and paints

Thermal conductivity to plastics, rubbers and paints

Pigmentation of paints and varnishes, coloration of plastics and rubber

Using percolation curves together with the dependences of mechanical properties or compounding parameters on volume resistivity help to the plastic converters to estimate the compound properties during processing alongside with its final mechanical parameters.

Materials: PA6 (MFR 230 °C/2.16 kg = 6 g/10 min), PBT (medium viscosity), PC (MFR 300 °C/1.2 kg = 20 g/10 min), PS (MFR 200 °C/5 kg= 3-4 g/10 min), POM (MVR 190 °C/2.16 kg = 12 cm3/10 min), PET (granulated flakes)

Since the electrical properties of compounds strongly depend on mixing quality and processing technique, Unipetrol recommends to perform all tests in accordance with the technical standards valid for the product, before taking a final decision about the compound composition.
