DGK-ABS KJD890TM Transparent Antistatic ABS Material Procurement Guide

Current selection pain points for transparent antistatic ABS

Purchasing transparent antistatic ABS usually fails around three connected issues: transparent molded parts show haze, resistance shifts after cleaning or seasonal humidity changes, and the material route cannot keep transparency and long-term antistatic behavior at the same time.

Transparent ABS parts are sensitive to drying, injection temperature, mold temperature and shear. Thin-wall packaging covers, medical device windows and clean observation panels can turn cloudy when local flow history increases scattering. At the same time, short-life coatings or humidity-dependent antistatic agents may pass incoming inspection but lose function after wiping, washing or winter low humidity.

DGK-ABS KJD890TM is positioned for buyers who need the two targets together: optical visibility and stable static dissipation. It uses a polymeric permanent antistatic modification route, not carbon black, so the part can remain transparent while maintaining 10^8-10^10 ohm surface resistivity.

DGK-ABS KJD890TM technical specification and molding window

DGK-ABS KJD890TM transparent permanent antistatic ABS is compounded from transparent ABS and a polymeric permanent antistatic system. The antistatic component is anchored in the resin phase and does not rely on a temporary surface coating, so repeated washing, alcohol wiping and storage have much less influence on resistance stability.

The grade is a high-flow injection molding material. Its MFR of 48 g/10 min at 220 C / 10 kg helps fill transparent thin-wall lids and observation covers. The purchasing review should still confirm target mold geometry, wall thickness, gate position and haze after trial molding.

Case 1: transparent antistatic chip packaging box

A precision packaging company in East China supplied transparent antistatic boxes for semiconductor packaging and testing plants. Operators needed to identify chips and sensors without opening the lid, while surface resistivity had to remain in the 10^8-10^10 ohm range to prevent dust attraction and ESD risk.

The original imported material passed shipment data, but mass injection molding created local haze and uneven resistance. The gate area measured lower resistance, the flow end measured higher resistance, and the finished-part yield stayed around 82%. The root cause was poor compatibility between the antistatic phase and ABS: orientation during flow created resistance nonuniformity, and scattered domains produced foggy areas.

DEYU ran three rounds. Round one used the recommended 85 C drying for 4-5 h, 195-210 C injection and 70 C mold temperature; transmittance was about 85% and surface resistivity reached 3.2 x 10^9 ohm, but slight haze remained. Round two found haze in 1.2 mm thin walls and at the flow end, so mold temperature was raised from 70 C to 75 C and injection was changed to slow-medium-slow. Round three removed the haze and stabilized resistance from 2.8 x 10^9 ohm near the gate to 3.5 x 10^9 ohm at the far end.

The customer made DGK-ABS KJD890TM the standard material for that box. After six months of continuous supply, batch resistance Cpk stayed at or above 1.33.

Case 2: medical sterile packaging box

A domestic medical equipment brand produced transparent sterile boxes for surgical instruments, implant accessories and precision diagnostic devices. The box needed high transparency, antistatic dust control and resistance to frequent alcohol disinfection.

The previous solution used ordinary clear ABS with a sprayed antistatic coating. It passed at delivery, but after three to six months the coating was consumed by daily alcohol wiping. Resistance failed and instruments attracted fine dust, creating a cleanability risk for medical use.

After switching to DGK-ABS KJD890TM, the customer validated 500 alcohol wipes, 15% RH low-humidity stability and 60 C water exposure for 24 h. Resistance stayed in the 10^8-10^9 ohm/sq range after wiping, changed less than 2x under low humidity and rose less than 30% after warm water exposure.

The material has now supported 150,000 delivered pieces with zero customer complaints. Beyond medical monitor panels, the same material direction is used for semiconductor cleanroom observation windows, optical inspection equipment panels and drone ground-station display covers.

Case 3: transparent powder storage jar

A pharmaceutical equipment customer produced transparent powder storage jars for drug intermediate packaging and powder dosing. Operators needed to see powder level and flow state, while static charge had to be dissipated to prevent powder sticking to the wall.

Ordinary clear ABS generated charge through powder filling, pouring and conveying. Fine powder accumulated on the inner wall, hiding the powder level and making each dosing amount less stable. Sprayed antistatic agents wore away during friction and cleaning; black conductive ABS solved static but removed visibility.

With DGK-ABS KJD890TM, the jar maintained about 85% transmittance at 2 mm, surface resistivity stayed around 10^8-10^9 ohm/sq, and powder wall sticking was significantly reduced. The customer also confirmed stable resistance after 500 alcohol wipes.

The final result was clear powder-level observation, less residue on the vessel wall, improved dosing accuracy and permanent antistatic behavior that did not depend on a temporary coating.

Procurement validation process and selection conclusion

Before a bulk order, buyers should request the full datasheet and test reports, including at least three consecutive lots of surface resistivity and transmittance data. The next step is a small-batch mold trial on the target tool, with resistance measured at the gate, middle, thin wall, weld line and flow end.

Accelerated aging should include at least 500 alcohol wipes, 15% RH for 48 h and damp-heat or storage checks according to the final use environment. Supply review should cover MOQ, lead time, batch consistency and technical support. DEYU supports 5 kg validation and 72 h sample delivery for this type of project.

The key purchase parameters for DGK-ABS KJD890TM are surface resistivity of 10^8-10^10 ohm, about 85% transmittance at 2 mm, MFR 48 g/10 min at 220 C / 10 kg and resistance Cpk at or above 1.33 in validated production. It is most suitable when the part must stay visible, clean and antistatic over long service life.
