Product Name
Carbon Black Conductive HIPS Compound | Anti-static HIPS Black Pellets for Semiconductor Carrier Tape
Brief Introduction
As a professional carbon black filled HIPS solution, this conductive HIPS compound is a type of permanent conductive polystyrene manufactured as uniform black plastic pellets. We adopt premium virgin high-impact polystyrene together with high-purity conductive carbon black, and apply twin-screw high-shear dispersion craft to produce this thermoforming conductive PS.
Our finished conductive carrier tape material features a steady surface resistivity ranging from 10⁴ to 10⁵ Ω/sq. Thanks to superior carbon black dispersion performance, its resistivity stays highly consistent with minimal batch-to-batch deviation.
Different from temporary anti-static plastic, this ESD conductive polystyrene owns intrinsic permanent conductive properties. The stable conductive network forms inside the polymer matrix, so the ESD protection function will not decay under temperature changes, high humidity or long-term storage. Meanwhile, the material boasts balanced melt fluidity, perfectly fitting the high-speed extrusion production of ESD packaging plastic sheets.
Three Core Industry Pain Points This Conductive Plastic Solves
- Pain Point 1: Unstable resistivity and failed ESD protection
Common low-grade conductive PS often generates obvious resistivity drift after high-temperature extrusion or half-year storage. Unstable static dissipation will trigger electrostatic discharge and damage precision IC chips.
Our carbon black filled HIPS builds a dense and intact conductive network inside the material, with resistance fluctuation controlled within 0.5 order of magnitude. It delivers reliable long-term anti-static performance as qualified semiconductor carrier tape raw material.
- Pain Point 2: Poor carbon black dispersion, crystal spots and carbon powder precipitation
Many generic conductive compounds suffer uneven carbon black mixing, which leaves crystal points and fish eyes on sheet surfaces. Worse still, separated carbon black powder will contaminate semiconductor pins, resulting in mass customer returns.
Our multi-stage homogenizing dispersion technology guarantees evenly distributed carbon black inside the anti-static HIPS black pellets. No carbon precipitation or surface dust transfer happens during forming, fully meeting the cleanliness standards of precision electronic packaging.
- Pain Point 3: Insufficient toughness, thin sheet cracking during thermoforming
Most regular conductive polystyrene is inherently brittle. When producing thin 0.25–0.6mm carrier tape sheets, cracks and white creases easily appear in the embossing, slitting and winding processes.
Our modified HIPS substrate greatly improves impact resistance and ductility. Punch processing won't cause rupture or obvious whitening, greatly raising the finished product yield of carrier tape manufacturers.
Application
This RoHS & REACH compliant conductive plastic is exclusively developed for manufacturing embossed semiconductor carrier tape, the mainstream ESD packaging plastic for static-sensitive SMT electronic components.
It is widely used to store and transport IC chips, resistors, capacitors, diodes, connectors, LEDs and other semiconductors. The material matches high-speed single-layer or three-layer co-extrusion equipment, supporting punch for 8mm to 104mm wide jumbo carrier tape rolls.
Numerous carrier tape manufacturers from Asia and European countries choose our static dissipative carrier tape material as their stable raw material.
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.
