#### What Is HIPS Antistatic Masterbatch?

HIPS antistatic masterbatch is a specially modified thermoplastic permanent antistatic additive. The masterbatch itself has a surface resistance of 10^7 Ω, and the extruded sheet reaches 10^8–10^9 Ω after dosing. Its advantages are long-term antistatic performance, no surface migration, no precipitation and no powder drop. The addition level is 50%–75%, and it can also be used directly on its own to achieve lower surface resistance.

The base material of HIPS antistatic masterbatch is high-impact polystyrene (HIPS), produced by introducing rubber components into general-purpose polystyrene. It is a two-phase system made up of a rubber phase and a continuous polystyrene phase, and the appearance is normally opaque or milky-white pellets. Antistatic HIPS offers some resistance to weak acids and weak bases but is more sensitive to strong acids, strong bases and aromatic hydrocarbon solvents.

#### How the Antistatic Mechanism Works

Permanent antistatic agents such as polyether ester block polyamide resins and polyethylene oxide are added to form a conductive network inside the material. Static charge is conducted through the material rather than accumulating on the surface. HIPS antistatic masterbatch has good flowability and thermal stability: during extrusion it passes smoothly through the screw, die and mold of the extruder to form sheets, pipes, profiles and other shapes.

The masterbatch retains the high impact strength and toughness of HIPS itself, so finished parts withstand a certain level of external impact without cracking easily. After extrusion molding, parts show high dimensional accuracy and low shrinkage, holding a stable shape and size that meets strict dimensional requirements across application fields.

#### Main Application Areas

##### Electronics

**Electronic component trays** — used for IC trays, LCD trays, electronic parts trays and FPC trays. They effectively prevent static electricity from damaging electronic components and keep components stable during transport and storage.

**Electronic product packaging** — formed into outer boxes and inner trays for electronics, preventing interference or damage from static accumulation, for example packaging for mobile phones and computers.

**Electronic device housings** — static-sensitive housings use HIPS antistatic masterbatch to gain mechanical protection while preventing static from affecting the internal circuitry.

*##### Packaging **Food packaging** — food trays and inner trays with good hygiene performance that can contact food directly without releasing harmful substances. Antistatic behaviour reduces dust pickup and keeps food packaging clean.**Consumer goods packaging** — cosmetics, stationery and similar daily necessities. Antistatic packaging picks up less dust and debris during transport and display, keeping the appearance clean and strengthening product image. ##### Other Fields **Medical equipment parts** — static-sensitive parts in medical equipment use HIPS antistatic masterbatch to prevent static interference with electronic components or sensors, protecting the accuracy and stability of the equipment.**Automotive interior parts** — instrument panels, door trim panels and similar components. Antistatic performance reduces dust pickup and keeps the interior clean, while good impact resistance meets automotive interior requirements. ### 3. FAQ (ready for FAQPage schema) **Q1: What is the surface resistance of HIPS antistatic masterbatch?** A: 10^7 Ω for the masterbatch itself; extruded sheet reaches 10^8–10^9 Ω at 50%–75% addition.**Q2: What is the dosage, and can it be used alone?** A: 50%–75% is recommended, and it can also be used directly on its own to reach lower surface resistance.**Q3: Will the antistatic effect migrate, precipitate or shed powder?** A: No. The system is permanently antistatic with no surface migration, no precipitation and no powder drop.**Q4: Which product forms can it produce?** A: Sheets, pipes and profiles by extrusion; also suitable for injection-molded housing parts.**Q5: How is chemical resistance?** A: Good tolerance to weak acids and weak bases; sensitive to strong acids, strong bases and aromatic hydrocarbon solvents, which should be avoided in service.**Q6: Does it keep the impact performance of HIPS?** A: Yes. Parts retain impact strength and toughness, with high dimensional accuracy and low shrinkage.  | Product Description | HIPS Antistatic Masterbatch | | --- | --- | | RenJie®Grade | 301AN/302AN | | Base Polymer | Polystyrene (HIPS) | | Material Characteristic | Antistatic Polystyrene | | Surface Resistance | 1.2×10E7 Ohms | | Appearance | Granules/lightly pale yellow | | Features | High impact streng | | Applications | ESD HIPS thermoforming film or sheet | | Processing | Extrusion/Injection |      ### Related products  View all*
