Product Name
Conductive PS Concentrate Used for ESD PS Thermoforming Sheet
Brief Introduction
We help ESD PS thermoforming Sheet Manufacturers to develop and supply the most suitable and economic Conductive PS concentrate, this products also be widely called conductive PS additive or conductive PS masterbatch. It is compounded by super conductive carbon black and High-impact Polystyrene resin, with perfect performance of dispersion after blended with PS resins.
Three Core Industry Pain Points This Conductive Plastic Solves
- Pain Point 1: Poor carbon black dispersion
Ordinary conductive masterbatch exhibits poor carbon black dispersion, resulting in significant lateral and longitudinal resistance deviations in extruded sheets and localized insulation blind spots; filters frequently clog, and sheets are covered with carbon black crystals and pitting.
Sugo's Solution: High-structure nano-carbon black multi-stage pre-dispersion process. Using special high-end conductive carbon black, processed through twin-screw multi-stage shearing and coating, the carbon black is free of hard agglomerates, extrusion does not clog filters, sheets are free of crystals, and the resistivity dispersion of the entire roll of sheet is extremely low.
- Pain Point 2: Failing to meet IEC61340 electronic packaging standards
During vacuum deep stretching and thermoforming of PS sheets, the conductive pathways formed by overlapping carbon black are stretched and broken, causing a surge in resistance on the tray sidewalls and thin-walled areas, failing to meet IEC61340 electronic packaging standards. Shallow cavities pass, while deep cavities are scrapped, resulting in a yield rate consistently below 85%.
Sugo's Solution: Three-Dimensional Stable Conductive Network Formulation Design
Utilizing a PS carrier + compatible toughening composite system, carbon black forms a three-dimensional interwoven conductive framework. The conductive pathways will not break even with a vacuum forming stretch ratio within 1:3. The resistance of the trays in both deep and shallow cavities remains stable at 10⁴~10⁸ Ω/sq, providing permanent conductivity without blooming and unaffected by temperature and humidity.
Application
This RoHS & REACH compliant conductive PS masterbatch is designed specially for ESD thermoforming PS sheets or rolls, the final product after vaccumed formed is IC tray for semi-conductors and sensitive parts of auto-mobiles.
Compliance Certifications
This conductive HIPS compound fully meets mainstream EU environmental standards for electronic packaging export:
1. REACH Regulation (EC 1907/2006): All SVHC substances are controlled below legal restricted thresholds;
2. RoHS 2.0 Directive 2011/65/EU: Free of lead, mercury, cadmium, hexavalent chromium, PBB and PBDE flame retardants.
Complete test reports and MSDS files can be provided to support customs clearance for all EU ports.
