L05183AB is a white ABS dye colour grade developed for injection‑molded appearance parts. The material combines stable flow properties, documented mechanical performance, and batch‑to‑batch color tolerance within ΔE*ab ≤ 0.3. This article covers its key characteristics, production control standards, and delivery framework.
Material Properties
L05183AB is tested against GB/T standards. The table below presents the measured values from the test report. For reference, publicly available data for a widely referenced ABS grade (Lotte Starex SD-0150 W91268), published under ISO standards, is shown alongside.
| Property | L05183AB (GB/T) | Reference Grade (ISO) |
|---|---|---|
| Melt Flow Index (200°C, 5kg) | 2.3 g/10min | 2.2 g/10min |
| Tensile Strength (50mm/min) | 43 MPa | 44 MPa |
| Flexural Strength (2mm/min) | 70 MPa | 70 MPa |
| Flexural Modulus (2mm/min) | 2410 MPa | 2400 MPa |
| Notched Izod Impact (23°C) | 20 kJ/m² | 20-21 kJ/m² |
| Specific Gravity | 1.07 g/cm³ | 1.04 g/cm³ |
The data for L05183AB is based on the test report from Qingdao Primetech Plastics Co., Ltd. All test specimens showed no abnormalities, and the material was qualified as conforming.
It should be noted that the two grades are tested under different standard systems — GB/T for L05183AB and ISO for the reference grade. While GB/T standards in China are largely harmonized with ISO in terms of test methodologies (GB/T 1040.2 corresponds to ISO 527-2, GB/T 1843 to ISO 180, GB/T 9341 to ISO 178, and GB/T 3682.1 to ISO 1133), the values are presented for reference and comparison purposes only.

The 2.3 melt flow index places L05183AB in the mid‑flow range for ABS dye colour applications. This supports stable cavity filling across part geometries from flat panels to ribbed enclosures. The 2410 MPa flexural modulus provides rigidity for housing applications while retaining ductility for snap‑fit assemblies.
For production teams, the value of these numbers is predictability. When incoming lots show consistent MFI and modulus, the molding press delivers consistent output. No unexpected pressure shifts. No unplanned cycle time adjustments.
Batch Color Tolerance at ΔE*ab ≤ 0.3
White reflects everything. Unlike dark colors that mask minor variations, white reveals shifts in base resin yellowness, pigment dispersion, and thermal history during dye colouring.
L05183AB is produced with a batch‑to‑batch color tolerance of ΔE*ab ≤ 0.3 (D65 illuminant, 10° observer). This is below the just‑noticeable difference threshold for the human eye under controlled lighting.
Three production variables are controlled to maintain this tolerance:
Titanium dioxide feed rate: TiO₂ is the primary white pigment. Feed variation shifts L* (lightness) and b* (yellowness‑blueness).
Base resin yellowness index: ABS natural color varies by catalyst and antioxidant package. Each incoming lot is measured before dye colouring.
Ash content: Serves as a proxy for total pigment loading. Consistent ash means stable opacity and tint strength.
Each L05183AB shipment includes a color measurement report showing ΔE*ab against the approved master standard. This gives incoming quality control a clear pass/fail criterion. For procurement teams, this removes ambiguity from color acceptance and reduces disputes at the receiving dock. The specified tolerance ensures that what you approve in the sample matches what arrives in production quantities.
Color measurement under D65/10° conditions is standard practice for white and light‑colored materials. L05183AB is produced to maintain ABS color consistency across multiple production runs, reducing the need for line adjustments when switching batches.
Production Lead Times
L05183AB is dyed and inventoried locally in China. Standard production lead times:
◆Samples
3 days for color‑matched samples
◆Production quantities
7 days for standard colors
These lead times refer to production completion. Actual delivery to the customer location depends on shipping distance and the selected logistics method. For customers requiring expedited shipping, arrangements can be discussed at the time of order.
The paid sample policy — samples are charged, with fees credited against future orders — ensures that sample lots come from standard production runs. Samples pulled from regular inventory behave the same way production lots do. This eliminates the common issue where specially prepared samples perform differently than mass‑production material.

The supply chain operates through Qingdao Prime Union Trade Co., Ltd., which maintains base resin inventory across four regional warehouses. Dye colouring is performed by Qingdao Primetech Plastics Co., Ltd., the group's in‑house color compounding and modification facility. Base resin selection, pigment addition, and quality control operate under a single management chain.
For customers using bonded warehouse or processing trade arrangements, additional logistics support is available. This integrated model allows for consistent material from raw resin to finished dyed product, with documented traceability at each step.
Technical Service and Support
Material performance on a datasheet is one thing. Performance on a customer's molding floor is what matters.
Our technical service team provides support at multiple levels:
●Domestic on‑site support
For customers within China, application engineers are available to visit customer facilities for material evaluation, trial run assistance, and production troubleshooting. This includes initial sampling support, process parameter review, and root‑cause analysis for molding issues. On‑site visits are typically coordinated within days of a request.
●Overseas remote support
For international customers, we provide technical consultation via online channels. This covers material selection guidance, processing recommendations, and quality documentation review. Remote support is coordinated through our sales and engineering teams, with response times aligned to customer time zones.
Support is not limited to the trial phase. We maintain communication with customers throughout the production cycle to address issues as they arise. The experience gained from each application contributes to our understanding of how materials perform across different equipment, mold designs, and production environments.

For customers in regions without direct on‑site coverage, we provide detailed technical documentation and remote troubleshooting support. Video‑assisted diagnostics and sample analysis are available to resolve processing challenges without requiring in‑person visits.
What Procurement Teams Should Know
L05183AB offers a specified color tolerance that removes ambiguity from incoming inspection. The ΔE*ab ≤ 0.3 specification provides a clear acceptance standard.
The production lead times support inventory flexibility. Shorter production cycles mean lower safety stock requirements without increasing supply risk.
For engineering teams, the documented mechanical properties provide a stable baseline for part design and mold setup. The material runs on standard ABS processing equipment with typical parameters for mid‑flow ABS dye colour grades.
When evaluating white ABS options, procurement and engineering teams can reference both the L05183AB test data and the published values of established grades. This allows for an informed assessment of how L05183AB fits within existing material portfolios and processing environments.
The integrated supply chain — from base resin distribution through Qingdao Prime Union Trade Co., Ltd. to dye colouring at Qingdao Primetech Plastics Co., Ltd. — provides a single point of accountability for material quality. This eliminates the coordination gap that sometimes occurs when raw material and coloring are handled by separate, unrelated suppliers.

Summary
L05183AB is a white ABS dye colour grade built around predictable flow, measurable color consistency, and responsive domestic supply. The material data is documented, the color tolerance is specified, and the production framework is designed for reliable fulfillment.
The defining characteristics are a tight color tolerance (ΔE*ab ≤ 0.3), stable flow properties (2.3 MFI), and mechanical performance that supports general‑purpose structural and cosmetic applications. Technical service support is available both on‑site for domestic customers and remotely for overseas customers.
If your current white ABS supply chain creates variability in color or production, or if you are exploring domestic options with responsive lead times, L05183AB is worth reviewing. The 3‑day sample production lead time provides a low‑commitment way to verify performance on your own equipment. Sample fees are applied as credit toward the first production order.
