DGK-ABS KJD890TM: Transparent Antistatic ABS and the Technical Difficulty Behind Clear ESD Materials
DGK-ABS KJD890TM is a transparent long-lasting antistatic ABS compound developed by DEYU for injection-molded parts that need both visible clarity and static-control performance.
Product Summary
DGK-ABS KJD890TM is a transparent long-lasting antistatic ABS compound developed by DEYU for injection-molded parts that need both visible clarity and static-control performance.
For transparent ESD parts, compare DGK-ABS KJD890TM transparent antistatic ABS with the broader antistatic plastics platform before locking haze, impact strength, and surface resistance targets.
Transparent antistatic ABS is more difficult than black conductive ABS. In black conductive materials, carbon black or conductive filler can easily build a conductive network, but transparency is lost. For transparent ABS, the formulation must reduce static accumulation while keeping clarity, surface quality, impact balance, and stable molding.
DGK-ABS KJD890TM is suitable for communication equipment covers, electronic device housings, transparent protective covers, display-side plastic parts, dust-sensitive transparent components, and industrial transparent ABS parts requiring antistatic performance.
The material is not designed as a high-conductive black plastic. It is positioned for transparent antistatic and static-dissipative applications where appearance and clarity are important.
1. Why Transparent Antistatic ABS Is Difficult
1.1 Conductive Fillers Usually Destroy Transparency
Many conductive plastics rely on carbon black, graphite, carbon fiber, or other dark conductive fillers. These routes are effective for resistance reduction, but they turn the material black or dark.
For transparent ABS, these routes are usually not suitable. The material needs an antistatic system that can work without strongly increasing haze or changing color.
1.2 Antistatic Additives May Cause Haze or Migration
Some antistatic agents migrate to the surface. They may reduce static temporarily, but they can also create surface blooming, unstable resistance, fogging, surface stickiness, printing or coating problems, and weak long-term performance.
For transparent parts, even a small surface defect can be visible. This makes formulation control more demanding.
1.3 Transparency and Impact Strength Must Be Balanced
Transparent ABS often needs both appearance and toughness. If the antistatic system is not compatible with ABS, impact strength and elongation may decrease.
For housings, covers, and protective parts, the material must not only look clear. It must also survive assembly, handling, screw tightening, and drop impact.
1.4 Molding Stress Affects Optical Appearance
Transparent parts show flow marks, stress whitening, weld lines, and internal stress more easily than opaque parts.
For this reason, material design and injection molding process must be considered together.

3. Technical Route: How DEYU Balances Transparency and Antistatic Performance
3.1 Transparent-Compatible Antistatic System
DEYU avoids simply using black conductive fillers for this type of material. The technical route focuses on transparent-compatible antistatic modification to reduce surface resistance while maintaining clarity.
3.2 Long-Term Antistatic Direction
For transparent electronic covers, short-term antistatic performance is often not enough. The material needs more stable resistance during storage, handling, and actual use.
DGK-ABS KJD890TM is positioned as a long-lasting antistatic ABS, not a temporary surface-treatment solution.
3.3 ABS Processing and Flowability
The melt flow index of 46.4 g/10 min gives the material practical flowability for injection-molded covers and housings. This helps reduce filling difficulty for transparent parts, but the final appearance still depends on mold design and processing control.
3.4 Impact and Surface Balance
Transparent antistatic ABS cannot be evaluated only by resistance. DEYU's formulation direction also considers tensile strength, flexural strength, elongation, notched impact, and molded surface stability.
4. Application Scenarios
4.1 Transparent Covers for Communication Equipment
Communication equipment often needs transparent or semi-transparent covers for visual inspection, display areas, indicator windows, or protective shells.
Material requirements include clear appearance, reduced dust attraction, stable antistatic performance, good molding flow, acceptable impact strength, and stable assembly.
DGK-ABS KJD890TM is suitable when ordinary transparent ABS attracts dust or accumulates static charge during operation.
4.2 Electronic and Electrical Equipment Parts
For electronic and electrical equipment, static accumulation can cause dust adhesion, handling discomfort, and ESD-related concerns.
Possible parts include transparent protective covers, display-side housings, inspection windows, device shells, instrument covers, and electronic equipment panels.
The material should be tested on final molded parts, especially if the product has thin walls, snap-fit structures, screw bosses, or strict appearance requirements.
4.3 Dust-Sensitive Transparent Components
Transparent parts easily show dust and fingerprints. If ordinary ABS attracts dust, product appearance can degrade quickly.
DGK-ABS KJD890TM can help reduce surface static accumulation, dust attraction, cleaning frequency, appearance complaints, and static-related handling issues.
For outdoor transparent parts, UV resistance should be evaluated separately because transparency and UV stability require additional formulation balance.
5. Processing Reference
Typical injection molding reference:
| Processing item | Reference value |
|---|---|
| Drying temperature | 90 °C |
| Drying time | 3-4 hours |
| Injection temperature | 205-220 °C |
| Mold temperature | Around 80 °C |
For transparent antistatic ABS, processing should focus on reducing internal stress, avoiding excessive shear, controlling drying quality, reducing flow marks, balancing injection speed and holding pressure, and checking transparency on final parts.
Final resistance and transparency should be validated on actual molded parts, because part thickness, gate position, flow length, and molding stress can affect both surface resistance and optical appearance.
6. Customer Case: Transparent ABS Cover With Dust Adhesion Problem
Original Situation
A customer used ordinary transparent ABS for an electronic equipment cover. The part looked good after molding, but after several days of use, dust accumulated quickly on the surface. The transparent cover looked dirty, and cleaning frequency increased.

7. Purchasing Guide
Before selecting transparent antistatic ABS, buyers should confirm target surface resistance range, transparent or translucent requirement, acceptable haze level, part thickness, molding method, surface appearance standard, impact requirement, whether UV resistance is required, whether flame retardancy is required, and testing method on the final molded part.
A professional inquiry should not only say "transparent antistatic ABS." It should include application, resistance target, transparency requirement, part drawing, thickness, and acceptance standard.
