DGK-PP DD2-3A Conductive PP Compound: Low-Resistance Polypropylene for Shielding, ESD, and Industrial Components

Product Summary

DGK-PP DD2-3A is a conductive PP compound from DEYU Plastics designed for parts that need a stronger conductive pathway than ordinary antistatic PP or static-dissipative PP.

For direct product selection, review DGK-PP DD2-3A conductive PP and the broader conductive plastics platform. DEYU can adjust resistance, stiffness, shrinkage, flowability, impact balance and additional functions around the actual molded part.

Its key feature is low surface resistance in the 10^2-10^3 ohm direction, making it suitable for applications where static charge must be transferred quickly, or where plastic parts need conductive, shielding, or resistance-connection functions.

Compared with ordinary PP, DGK-PP DD2-3A provides:

lower surface resistance; black conductive appearance; lightweight polypropylene base; injection molding processability; good stiffness for PP-based conductive parts; controlled shrinkage direction; customizable formulation potential.

This material is not positioned as a general antistatic PP. It is more suitable for conductive PP applications where stronger electrical performance is required.

1. Main Material Characteristics

Item	DGK-PP DD2-3A Typical Direction
Base material	PP composite compound
Color	Black
Form	Pellets / granules

Main feature	Low-resistance conductive PP

The surface resistance direction makes DGK-PP DD2-3A different from ordinary antistatic PP. In many projects, antistatic PP targets 10⁹–10¹² Ω, static-dissipative PP targets 10^6-10^9 ohm, while DGK-PP DD2-3A is designed toward a much lower resistance range.

2. Mechanical Performance Direction

DGK-PP DD2-3A is not only a conductive material. It also needs to maintain practical mechanical performance for injection-molded parts.

Typical data direction:

flexural strength: 36.2 MPa; flexural modulus: 3472 MPa; tensile modulus: 5570 MPa; tensile strength: 23.1 MPa; elongation at break: >14%; Izod notched impact strength: 112 J/m.

For conductive PP compounds, electrical performance often affects toughness, flowability, and surface quality. The value of DGK-PP DD2-3A is that it provides a low-resistance conductive network while still keeping a usable stiffness and molding window for industrial parts.

3. Why Choose Conductive PP Instead of Ordinary PP?

Ordinary PP is lightweight and cost-effective, but it is an insulating material. In dry, high-speed, powder-contact, or electronic equipment environments, ordinary PP may cause:

static charge accumulation; dust adhesion; powder sticking; unstable part release; feeding interruption; ESD risk; sensor interference; difficulty in grounding design.

DGK-PP DD2-3A is more suitable when the problem is not simply dust reduction, but stronger charge transfer or conductive function.

Typical selection logic:

choose antistatic PP when only dust reduction is needed; choose static-dissipative PP when controlled discharge is required; choose DGK-PP DD2-3A when low resistance and stronger conductivity are required.

4. Application Scenarios

4.1 Shielding and Electronic Equipment Components

DGK-PP DD2-3A can be used in plastic parts where conductive PP is required for shielding-related or electronic equipment applications.

Typical parts:

shielding housings; electronic equipment covers; conductive connectors; industrial electronic components; interference-control parts; custom molded conductive PP parts.

Selection focus:

surface resistance on the final part; part thickness; grounding design; dimensional stability; impact requirement; assembly method.

4.2 Conductive Connectors and Resistance-Connection Parts

The low surface resistance direction of DGK-PP DD2-3A makes it suitable for molded parts that need a conductive path or resistance-connection function.

Typical requirements:

stable resistance after molding; black conductive surface; injection molding repeatability; low shrinkage fluctuation; sufficient stiffness for assembly.

The final resistance should be tested on the actual molded part, because conductive filler orientation, wall thickness, gate position, and molding parameters can affect measured resistance.

4.3 Industrial Trays, Covers, and Functional Parts

DGK-PP DD2-3A may also be considered for industrial trays, covers, and parts where ordinary PP causes static-related problems.

Typical problems it can help address:

dust accumulation; powder adhesion; part sticking; unstable feeding; static-related handling issues; need for lightweight conductive plastic.

For parts requiring wear resistance, flame retardancy, UV resistance, or low warpage, DEYU can further adjust the formulation based on the target application.

5. Processing Reference

Typical injection molding reference:

drying temperature: 90 C; drying time: 4–5 hours; injection temperature: 210-220 C; mold temperature: around 80 C.

Processing should be adjusted according to machine type, mold structure, part thickness, flow length, gate design, and final resistance target.

For conductive PP compounds, processing stability is important because dispersion and flow orientation may affect resistance consistency. DEYU recommends validating both standard test pieces and final molded parts.

6. Purchasing and Validation Guide

Before purchasing DGK-PP DD2-3A, buyers should confirm the following points.

Electrical Requirement

target surface resistance; surface or volume resistance test method; testing on standard specimen or final part; humidity and temperature during testing; grounding or shielding design requirement.

Part Requirement

part thickness; injection molding process; gate position; shrinkage tolerance; warpage requirement; assembly method; impact requirement.

Additional Function

flame retardancy; wear resistance; UV resistance; low-temperature toughness; surface smoothness; color requirement; cost target.

A clear inquiry should not only say “conductive PP.” It should define the resistance range, application, test method, part drawing, and mechanical requirements.

7. DEYU DGK Conductive PP Platform

DEYU Plastics can develop conductive PP materials according to different resistance and application targets.

Available directions include:

DGK-PP DD2-3A low-resistance conductive PP; conductive PP masterbatch route; static-dissipative PP; conductive PP for trays and covers; conductive PP for powder-contact parts; conductive PP with low-warpage adjustment; conductive PP with impact balance; conductive PP with flame-retardant modification; conductive PP with UV-resistant modification.

DGK-PP DD2-3A is suitable when customers need a black conductive PP compound with a low surface resistance direction and injection molding processability.

Conclusion

DGK-PP DD2-3A is a DEYU conductive polypropylene compound designed for low-resistance PP applications. Its 10^2-10^3 ohm surface resistance direction makes it more suitable for conductive, shielding, resistance-connection, and industrial static-control parts than ordinary antistatic PP.

For buyers, the key is to confirm whether the project really needs conductive PP or only antistatic PP. If the product only needs dust reduction, a higher-resistance antistatic PP may be more suitable. If the product requires strong charge transfer, shielding-related function, or low-resistance conductive performance, DGK-PP DD2-3A is a practical material direction.

Final selection should be based on actual molded-part testing, including resistance, shrinkage, impact, surface quality, and application performance.
