Global Antistatic Plastic Solutions Provider: From Standard Grades to Custom-Formulated Options
In key global manufacturing sectors including semiconductor packaging and testing, electronic component handling, cleanroom equipment, new energy vehicles and industrial automation, electrostatic protection has become a mandatory technical requirement in plastic part selection. Traditional antistatic approaches often rely on conductive carbon black filling or surface coating. Carbon black can deliver low resistance, but it usually creates opaque black materials and may reduce impact toughness. Surface coating can be transparent, but it may lose effectiveness over time, after wiping or under changing ambient humidity.

This document provides systematic reference information on DEYU antistatic plastics, including technical routes, product range, in-depth application cases and selection guidelines.
1. Technical Routes for Antistatic Plastics and Their Application Boundaries
The common technical routes for electrostatic dissipation in engineering plastics can be summarized into three categories. Selection should consider resistance range, transparency, permanence, cleanliness, mechanical retention and process stability.
| Technical route | Mechanism | Typical surface resistivity | Transparency | Permanence | Main limitations |
|---|---|---|---|---|---|
| Conductive filler-filled system, including carbon black, carbon fiber and carbon nanotubes | Forms conductive pathways inside the polymer matrix | 10^3-10^6 ohm, conductive range | Opaque black in most cases; color adjustment is possible only in some systems | Permanent and normally unaffected by humidity | Impact toughness can decrease; carbon black may bring particle-shedding concerns |
| Polymer-type permanent antistatic agent modification | Hydrophilic or ion-conductive polymer forms a submicroscopic conductive network | 10^7-10^10 ohm, static-dissipative range | Transparent or translucent grades are possible | Permanent, wipe-resistant and washable when the formulation is correct | Requires good compatibility, dispersion control and substrate matching |
| Surface coating | Spray or dip coating with low-molecular-weight antistatic agents | 10^9-10^11 ohm, short-term antistatic range | Transparent coating is possible | Temporary and may degrade with time | Needs periodic re-application; not suitable as a permanent material solution |
Selection logic for global applications
| Requirement scenario | Recommended route | Rationale |
|---|---|---|
| Transparency plus long-term antistatic performance | Polymer-type permanent antistatic route | High light transmittance, permanent behavior and wipe resistance |
| Conductive level below 10^6 ohm where black is acceptable | Conductive carbon black filled route | High conductivity, mature processing and cost-effective production |
| Short-term or single-use antistatic packaging | Surface coating | Low cost and simple application |
| Cleanroom use requiring antistatic behavior and no particle shedding | Polymer-type permanent antistatic route | Smooth surface, no filler shedding and better cleanliness control |
| Wear resistance plus antistatic behavior | Compound modification combining conductive and lubricating components | Multifunctional performance, but normally requires custom formulation |

3. In-Depth Application Case Studies Validated by Global Customers
The following cases are based on joint validation between DEYU and domestic or international customers. The test data came from customer laboratories or third-party testing institutes.
Case 1: Semiconductor packaging and testing, transparent permanent antistatic IC chip trays
A leading global semiconductor packaging and testing company used conventional ABS trays together with ionizing blowers during IC chip handling. The blowers had limited coverage, so static charge still accumulated on trays at the end of the line. Dust attraction around chip leads affected bonding yield. The customer wanted inherently antistatic trays while maintaining transparency for automated visual orientation recognition.
DEYU selected DGK-ABS KJD890TM transparent permanent antistatic ABS. The purpose was to combine stable surface resistivity, transparency and wipe resistance without depending on an external ionizing device.
| Test item | Test method | Result |
|---|---|---|
| Surface resistivity uniformity | IEC 61340-5-1, 23 C / 50% RH, 5 points per tray, 10 trays | Average 3.2 x 10^9 ohm, CV = 16% |
| Light transmittance | ASTM D1003, 2 mm thickness | Initial 85%, no visible haze |
| Wipe resistance | 75% alcohol swab, 500 wipes, followed by resistivity measurement | 4.1 x 10^9 ohm, no order-of-magnitude change |
| Particle shedding test | Simulated ultrasonic cleaning and liquid particle counting | Meets ISO Class 7 requirements |
Process adjustments included drying at 85 C for 4 h, moisture below 0.05%, melt temperature of 195-210 C, mold temperature around 70 C, SPI A-2 mold polish and a fan gate to avoid shear overheating.
Results over six months included a tray visual recognition pass rate of 99.8%, dust-related visual defects reduced from 0.3% to 0.02%, elimination of ionizing blowers and repeated washing or alcohol wiping without performance degradation.
Case 2: New energy vehicles, conductive PP battery module insulating bracket
A power battery module supplier originally used standard PP with metal grounding tabs. The tabs increased assembly complexity and occupied space. The customer wanted inherently conductive PP to dissipate static charge while also meeting flame-retardancy and long-term temperature requirements.
DEYU selected DGK-PP DD2-3A conductive PP with a target surface resistivity of 10^3-10^6 ohm, UL94 V-2 flame rating and an operating temperature range from -20 to 60 C.
| Test item | Test method | Result |
|---|---|---|
| Surface resistivity | GB/T 1401-2002, 10 parts x 5 points | Average 8.5 x 10^4 ohm, CV = 14% |
| Resistivity after thermal cycling | -40 C / +85 C, 90% RH, 200 cycles | 1.2 x 10^5 ohm, still in conductive range |
| Flame rating | UL94 | V-2 |
| Tensile strength | GB/T 1040.2 | 22 MPa |
| Mechanical retention after coolant exposure | 72 h in 50:50 ethylene glycol / water | Tensile strength retention 91% |
Process adjustments included drying at 80 C for 3 h, melt temperature of 200-230 C, mold temperature of 40-60 C, resistivity monitoring every 30 shots with back-pressure adjustment if CV exceeded 20%, and shrinkage compensation of about 1.5-1.8%.
The final results eliminated metal grounding tabs, reduced assembly steps from 5 to 3, reduced module weight by about 8%, kept resistivity CV below 15% across three consecutive batches, achieved a 100% ESD pass rate on the production line and lowered material cost by about 18% compared with the original solution.
Case 3: Electronics assembly, antistatic POM drive gear
An SMT placement machine manufacturer used standard POM gears with external grounding carbon brushes. The brushes wore quickly and had to be replaced weekly. Carbon dust also created contamination risk for PCBs. The customer wanted inherently antistatic POM gears while keeping low friction and low noise.
DEYU selected DGK-POM KJD789R, a wear-resistant and permanent antistatic compound POM.
| Test item | Test method | Result |
|---|---|---|
| Surface resistivity uniformity | IEC 61340-5-1, 10 parts x 5 points | Average 3.8 x 10^9 ohm, CV = 18% |
| Friction and wear comparison | GB/T 3960, 150 N / 0.42 m/s / 120 min, against 45# steel | Wear mass 26 mg; pure POM was 22 mg; +18% was acceptable |
| Gear rig endurance | 1.5 N.m, 20 rpm, 5000 h, resistivity and wear measured every 500 h | Resistivity 5.6 x 10^9 ohm after 5000 h, no drift; tooth wear below 0.04 mm |
| Wipe resistance | 75% alcohol, 500 wipes | Resistivity 4.2 x 10^9 ohm, no change |
Process adjustments included drying at 80 C for 3-4 h, moisture below 0.1%, melt temperature of 195-210 C, mold temperature of 90-100 C, gate location away from the gear tooth meshing area, and resistivity checks every 50 shots incorporated into the SOP.
The 5000-hour endurance test passed with acceptable gear clearance and stable resistivity. External carbon brushes were eliminated, maintenance and assembly were reduced, noise remained comparable to standard POM, placement accuracy stayed stable and no static-related placement offset failures were recorded.
