Antistatic Rotomoulding Powder
What is Antistatic Rotomoulding Powder?
Antistatic Rotomoulding Powder is a specialized polyethylene-based compound formulated for rotational moulding applications that require static charge dissipation. It combines the excellent processing and mechanical properties of standard rotomoulding materials with enhanced electrostatic discharge (ESD) protection.
This powder is engineered with antistatic additives that are uniformly blended and dispersed to prevent the buildup of static electricity during or after manufacturing, making it especially suitable for applications in sensitive, flammable, or dust-prone environments.
Features
Antistatic Functionality
Prevents accumulation of static electricity on the molded product surface, reducing the risk of sparks or dust attraction.
Uniform Particle Size Distribution
Provides consistent flow and sintering behavior in the mold for a smoother surface finish and defect-free production.
Excellent Mold Release & Flow
Ensures efficient production cycles with less waste and easy de-molding.
High Mechanical Strength
Retains durability, impact strength, and flexibility typical of high-quality rotomoulding materials.
UV Stabilized Grades Available
Optional grades with UV protection are offered for outdoor applications.
Color Customization
Can be pigmented to any color while maintaining antistatic properties (depending on the application).
Applications
- Electronics enclosures & device casings
- Chemical handling tanks and containers
- Fuel storage tanks
- Industrial dust bins
- Antistatic pallets and crates
- Medical waste bins
- Agricultural sprayer tanks
- Explosion-prone zones (e.g., refineries, chemical plants)

Processing & Handling Guidelines
To achieve optimal results with antistatic rotomoulding powder, follow these practices:
Drying
Ensure the powder is dry before processing. If exposed to moisture, pre-dry at 60–70°C for 2–4 hours.

Recommended between 200°C and 220°C.
Cooling
Avoid rapid cooling as it may affect surface quality.
Cleaning
Use clean, oil-free molds to prevent contamination.
Storage
Keep in sealed bags in dry, shaded areas.

FAQs
What is antistatic rotomoulding powder used for?
It is used to make plastic products through rotational molding that need to prevent static electricity buildup — ideal for electronics, chemicals, and flammable material handling.
How does it work?
The powder contains antistatic additives that lower the surface resistivity of the plastic product, allowing static charges to dissipate rather than accumulate.
Is it safe for food contact applications?
Only specific food-grade versions are available. If you’re targeting food applications, confirm with the supplier whether FDA or EU food contact compliance is available.
Can I get it in different colors?
Yes. However, colors should be chosen carefully as some pigments might reduce antistatic performance. Manufacturers typically provide compatible color options.
Is it available in UV-resistant grades?
Yes. If your application involves outdoor exposure, UV-stabilized versions are available upon request.
What is the difference between conductive and antistatic powders?
Antistatic powders reduce static buildup, while conductive powders actively conduct electricity. Antistatic is suitable for dissipating small charges; conductive is for critical ESD protection.
What molding machines can be used with this powder?
It is compatible with all standard rotomoulding machines including biaxial, shuttle, and rock-and-roll type machines.
Is there any special storage requirement?
Yes. Store in a dry, cool place away from moisture. Antistatic performance can be affected by humidity and improper storage.
Does the antistatic property degrade over time?
The antistatic effect may reduce over time depending on environmental exposure. Some grades use permanent antistatic agents for long-term effectiveness.
Can it be recycled?
Yes, in many cases. However, performance might vary after recycling. It’s recommended to test recycled material for critical antistatic applications.
