Transparent Plastics Antistatic Agent (MABS): Properties, Dosage and Applications

An antistatic agent for plastic transparency is an ESD additive designed for transparent polymers. It provides antistatic performance while preserving the transparency of ESD polymers. This article reviews the properties, dosage, processing methods and main applications of the 120T and 130T grades, and explains the core features of antistatic agents for transparent plastics.

1. What Is an Antistatic Agent for Transparent Plastics?

An antistatic agent for plastic transparency is an ESD additive designed for transparent polymers. It ensures the transparency of ESD polymers while providing an antistatic function. Commonly used antistatic agents for plastic transparency are based on MABS, PP, TPU, GPPS, PMMA, PVC, PETG and PCT.

The product has low dependence on humidity, which ensures that the surface resistivity of the end product changes little across different humidity environments.

2. Transparent Plastics Antistatic Agent Grades: 120T and 130T

120T: Permanent Antistatic Agent for Transparent ABS

120T is a permanent, internally added antistatic agent for transparent ABS. It prevents the static-related problems that occur on the surface of transparent ABS and has good compatibility with transparent ABS such as LG 558A and Toray 920-555. It can be processed by injection molding and extrusion, with a recommended dosage level of 10%~25 wt%. The resistance value of an ESD polymer containing 20% of 120T is about 10E8 ohms.

130T: Antistatic Masterbatch with No Compounding Required

130T is an antistatic masterbatch based on an antistatic agent for plastics. This ESD concentrate is suitable for ESD polymers with a resistance value of 10E10~10E11 ohms. It is directly dry-mixed at a ratio of about 10% and does not require compounding.

3. Applications of Transparent Plastics Antistatic Agents

120T and 130T are suitable for ESD transparent packaging sheets, ESD transparent packaging films and ESD transparent injection-molded parts. Their main applications are transparent IC chip trays and transparent IC containers in the semiconductor packaging industry, such as those used by Samsung Electronics and SK Hynix.

4. Five Core Features of Transparent Plastics Antistatic Agents

Maintaining High Transparency

While performing its antistatic function, the additive has little effect on the light transmittance of MABS resin. It is suitable for products with high transparency requirements such as optical devices and transparent plastic products, ensuring that products remain clearly visible without affecting the visual effect.

Minimal Impact on the Base Material

During compounding, the antistatic agent has no adverse effect on the basic properties of the material, including mechanical, thermal and chemical properties. This ensures that the product still maintains its original performance characteristics and quality standards after the antistatic agent is added.

Immediate and Long-Term Action

120T and 130T are both non-hygroscopic ionomer resins, which are permanent antistatic additives for plastics.

Convenient Use Across Production Stages

120T is favorable for compounders and can be processed by injection molding, extrusion and blow molding; 130T can be used directly in dry blending and is favorable for sheet or film manufacturers.

Low Addition Level and Better Cost Efficiency

The antistatic agent for plastic transparency requires a low addition amount, making it more cost-effective than buying ESD polymers or antistatic masterbatches.

5. Why the Self-Compounding Route Uses Less Additive

A notable advantage of antistatic agents for transparent plastics is their low addition level. Because the agent is added directly to an existing formulation, the dosage required is lower than that of purchasing ready-made ESD polymers or antistatic masterbatches, making it more cost-effective for the same performance target. In addition, 130T can be dry-mixed without compounding, removing one processing step.

6. Transparent Plastics Antistatic Agent FAQ

Q1: What are the recommended dosage and achievable resistance value of 120T?

The recommended dosage level of 120T is 10%~25 wt%. An ESD polymer containing 20% of 120T reaches a resistance value of about 10E8 ohms.

Q2: How is 130T used, and which resistance range does it cover?

130T is an antistatic masterbatch that is directly dry-mixed at a ratio of about 10% without compounding, and it is suitable for ESD polymers with a resistance value of 10E10~10E11 ohms.

Q3: Does it affect transparency or the performance of the base material?

No. It has little effect on the light transmittance of MABS resin and is suitable for products with high transparency requirements such as optical devices. Nor does it have adverse effects on the basic mechanical, thermal or chemical properties of the material during compounding.

Q4: Which resins is it compatible with?

120T has good compatibility with transparent ABS such as LG 558A and Toray 920-555. Commonly used antistatic agents for plastic transparency also cover substrates including MABS, PP, TPU, GPPS, PMMA, PVC, PETG and PCT.

Q5: Is it affected by ambient humidity?

It has low dependence on humidity, ensuring that the surface resistivity of the end product changes little across different humidity environments. Both 120T and 130T are non-hygroscopic ionomer resins.

Q6: Where is it mainly applied?

It is mainly used for transparent IC chip trays and transparent IC containers in the semiconductor packaging industry, as well as ESD transparent packaging sheets, ESD transparent packaging films and ESD transparent injection-molded parts.

Q7: Which processing methods can be used?

120T can be processed by injection molding, extrusion and blow molding and is favorable for compounders; 130T can be used directly in dry blending and suits sheet or film manufacturers.

Conclusion: How to Select an Antistatic Agent for Transparent Plastics

The core value of these antistatic agents lies in combining transparency with antistatic performance, with minimal impact on the base material and immediate, long-lasting action. Selection comes down to three points: first, match the grade to the target resistance — 120T for systems around 10E8 ohms and 130T for 10E10~10E11 ohm systems; second, choose the form that fits the production stage — 120T for compounding operations and 130T for direct dry blending at sheet or film lines; and third, confirm the transparency requirement, since the additive has little effect on the light transmittance of MABS resin and suits optical devices and transparent plastic products.
