Q1: What is a conductive PP compound?

A: It is a polypropylene (PP)-based multiphase composite material prepared by adding conductive materials such as carbon black, metal powder, metal fiber, carbon fiber and carbon nanotubes using physical or chemical methods, giving the material both a defined conductive function and good mechanical properties.

Q2: What is the difference between 0403C and 0405C?

A: 0403C is a carbon black filled conductive polypropylene that delivers uniformly conductive surfaces at a low 20–40 wt% loading, with glass fiber reinforced and flame retardant options available, and offers excellent conductivity, high strength and good corrosion resistance. 0405C can be used as a conductive masterbatch, with a loading that varies by processing technique — suitable for conductive connection components in electronic equipment and antistatic packaging.

Q3: What loading does a conductive PP compound require?

A: For 0403C, the carbon black filling level is 20–40 wt%. When 0405C is used as a conductive masterbatch, the addition amount depends on the specific processing technique and application.

Q4: Which processing methods can be used?

A: Extrusion, injection molding and blow molding are all suitable. The compounds also offer low dosages and convenient dry-mixing processing, with no need for major changes to existing equipment or processes.

Q5: Can conductive PP compounds be used in the semiconductor industry?

A: Yes. Wafer boxes and chip trays made of conductive PP compounds effectively eliminate static electricity, avoiding dust adsorption and chip damage from electrostatic discharge during wafer processing, storage and transportation.

Q6: Can conductive PP compounds be used for EMI shielding packaging?

A: Yes. They can be made into packaging materials with electromagnetic shielding functions that block or reduce the interference of external electromagnetic fields on internal electronic equipment — for example, packaging for high-end electronic instruments and communication equipment.
