1. What Is a Conductive PP Compound?

A conductive PP compound is a polypropylene (PP)-based multiphase composite material, prepared by adding various conductive materials — such as carbon black, metal powder, metal fiber, carbon fiber and carbon nanotubes — and using physical or chemical methods, so the resulting composite has a defined level of conductive function together with good mechanical properties.

1.1 0403C: Carbon Black Filled Conductive Polypropylene

0403C is a conductive polypropylene containing carbon black that offers uniformly conductive surfaces at a low loading of 20–40 wt%. Glass fiber reinforced and flame retardant grades are available. It combines multiple characteristics such as excellent conductivity, high strength and good corrosion resistance.

1.2 0405C: Conductive PP Compound Usable as a Conductive Masterbatch

0405C is a conductive PP compound that can be used as a conductive masterbatch. Its addition amount varies according to the processing technique. This compound has excellent conductivity and can meet the conductive performance requirements of different application scenarios, such as conductive connection components for electronic equipment and antistatic packaging materials.

1.3 Mechanical and Processing Performance

Conductive PP compounds retain some of the mechanical properties of the PP resin, and by adding appropriate fillers and additives they can also improve mechanical indicators such as strength and toughness to a certain extent.

They can be formed by common processing methods such as extrusion, injection molding and blow molding, offering low dosages, good conductivity, good stability and convenient dry-mixing processing.

2. Application Cases of Conductive PP Compound

2.1 Static Electricity Protection

In the fields of electronics and semiconductor production, static electricity can damage sensitive components. During the processing, storage and transportation of semiconductor wafers, wafer boxes and chip trays are needed to hold them.

Wafer boxes and trays made of conductive PP compounds effectively eliminate static electricity and prevent it from damaging wafers — for example, avoiding static electricity adsorbing dust or electrostatic discharge damaging chips.

Packaging materials made of conductive polypropylene composites conduct away static electricity generated during the packaging process, ensuring the safety of electronic components inside and preventing performance degradation or damage caused by static electricity.

2.2 Electronic Equipment Packaging

For the overall packaging of electronic products such as mobile phones, computers and tablets, conductive polypropylene composites can be made into packaging boxes, liners and similar parts. They effectively eliminate static electricity generated by friction during packaging and transportation, protecting the circuits and electronic components of electronic products from static interference.

2.3 Conductive Containers, IC Carrier Tape and EMI Shielding Packaging

Conductive PP compounds are also used for conductive containers, IC carrier tape and conductive PP corrugated boards.

They can be used to manufacture packaging materials with electromagnetic shielding functions, blocking or reducing the interference of external electromagnetic fields on internal electronic equipment and ensuring normal equipment operation and signal transmission accuracy — for example, packaging for high-end electronic instruments and communication equipment.
