What Is RENJIE® Antistatic Masterbatch?

RENJIE® antistatic masterbatch is a functional masterbatch with intrinsic antistatic behaviour. It delivers permanent antistatic performance that is independent of humidity, shows excellent compatibility with host resins and has minimal impact on product properties. It solves static problems in LLDPE film, PP stretch film, ABS sheet, PA6 sheet, TPU film and HIPS thermoforming sheet.

RENJIE® offers a range of permanent antistatic masterbatch grades compatible with LLDPE, HDPE, ABS, MABS, HIPS, PP, PA and TPU resins. Each grade is composed of a carrier, antistatic additives and other additives, giving low addition levels and an optimized overall cost.

RENJIE® Antistatic Masterbatch Grades and Where They Fit

PS302AN protects antistatic performance while keeping impact strength and mechanical properties intact.

How to Use

Dry-blend the masterbatch with the raw material at the recommended ratio, or compound it, then process directly by injection molding, extrusion or blow molding, making sure dispersion is uniform. The exact dosage is adjustable to product type, service requirements and processing technology. RENJIE® also provides customized solutions for special applications.

RENJIE® Antistatic Masterbatch Key Features

No exudation — Once RENJIE® antistatic masterbatch is mixed with resin and processed into finished parts, the antistatic components do not migrate from the interior to the surface, and no precipitate forms over time or with environmental change (temperature, humidity, friction). The reason is that the antistatic components sit stably in the resin matrix through chemical bonding rather than being released to the surface like some traditional small-molecule antistatic agents. No exudation keeps surfaces clean and avoids tackiness and blooming.

Long-lasting, stable effect — Unlike traditional antistatic agents, there is no induction period; performance survives wiping and washing and stays stable for 5–10+ years.

Humidity independence — Conductive behaviour is unaffected by air humidity, giving consistent performance across conditions and overcoming the humidity sensitivity of small-molecule antistatic materials.

Good compatibility — Customizable resin carriers ensure excellent compatibility with the host resin and even dispersion through the part.

Minimal impact on properties — Little effect on processing, colour or mechanical properties of the end product.

RENJIE® Antistatic Masterbatch Applications

Processing Methods and End Products

• Processes: injection molding, blow molding, blister/thermoforming, blown film, cast film.
• End products: packaging films (electronic packaging film, stretch film, bubble bags, flat bags), plastic sheets, antistatic packaging materials, vacuum cleaner parts, household tools, and surface materials or flooring for special environments such as dust-free workshops and flammable or explosive areas.

RENJIE® Antistatic Masterbatch Key Application Fields

Electronics — Electronic component packaging film and IC trays prevent static build-up and damage to sensitive components. The masterbatch is also used for antistatic flooring and work surfaces to create an antistatic production environment.

Medical — Medical device housings, medical catheters and surgical instruments. It prevents static from attracting dust and microorganisms that could affect medication or patients; transparent formulations also aid internal inspection.

Packaging — Food and pharmaceutical packaging benefit from reduced static attraction of dust and impurities, keeping contents clean and hygienic. It also suits precision instrument and optical lens packaging, preventing static-induced dust pickup from degrading product quality.

Automotive — Interior components and returnable packaging for parts in production workshops, as well as automotive fuel lines and similar parts where static poses a safety hazard.

Textile — Added to fibres it produces antistatic fabrics for workwear used in electronics workshops, petrol stations and similar sites, and for everyday clothing where static is a nuisance.

Will RENJIE® Antistatic Masterbatch Migrate?

Absolutely not.

The masterbatch RENJIE® produces is a long-lasting antistatic polymer material obtained by reactor polymerization. It forms a percolation network with conductive capability on the plastic surface to deliver the antistatic effect. Added to the base material by dry mixing, it offers non-migration, durability, strong environmental adaptability and water resistance.

Intrinsic dissipative antistatic masterbatch — Taking LLDPE antistatic masterbatch as an example, this type can be added during blending, extrusion or injection molding. It works through a continuous polymer phase: ions act as charge carriers to dissipate the electrostatic field, and they do not migrate to the surface of the finished part.

Carbon quantum dot composite antistatic masterbatch — Taking nylon antistatic masterbatch as an example, carbon quantum dots are introduced into the masterbatch by a specific process. The dots combine organically with the nylon molecular chain and disperse evenly through the nylon. They share a similar matrix structure with the resin and can form hydrogen bonds, delivering antistatic performance without migration.

Thermoplastic polyester elastomer antistatic masterbatch — Taking TPU antistatic masterbatch as an example, this long-lasting grade uses a TPEE (thermoplastic polyester elastomer) carrier. It is highly compatible with thermoplastic elastomers and other resins, and after dosing it achieves permanent antistatic performance with no migration and no exudate.

3. FAQ (ready for FAQPage schema)

Q1: Does RENJIE® antistatic masterbatch migrate or exude?

A: No. Antistatic components are bonded chemically into the resin matrix, so they do not migrate to the surface or form precipitates, and performance survives wiping and washing.

Q2: How long does the antistatic effect last?

A: 5–10+ years of stable performance, with no induction period — it works from the moment it is added.

Q3: Is performance affected by humidity?

A: No. Conductive behaviour stays consistent across humidity levels, overcoming the humidity sensitivity of small-molecule antistatic agents.

Q4: Which resins are supported?

A: LLDPE, HDPE, ABS, MABS, HIPS, PP, PA and TPU, with customizable carriers to ensure compatibility.

Q5: How is it added?

A: Dry-blend or compound at the recommended ratio, then process by injection molding, extrusion or blow molding with uniform dispersion; dosage is adjusted to product type and process.

Q6: Are there transparent options?

A: Yes — RENJIE® P109AN for PE-based film with minimal transparency loss, and RENJIE® 120T for transparent ABS in injection molding and extrusion.
