Why You Need Antimicrobial Product?
An Antimicrobial product developed with polymers ensures the upkeep of the product's hygiene, benefits the user, and warrants the overall well-being and health of the product's user.
An Antimicrobial product will ensure that all these snags can be avoided.
Often, the polymers are developed using a wide range of additives that retain moisture, giving rise to microbial infestation, which leads to the product's degeneration, discoloration, presence of algae causing green molds, the increase of unhealthy bacteria, malodor, and a destructive biofilm.
How does Antimicrobial Powder work?
- The unique silver ions that we use in the product with the silicone carrier are distributed uniformly across the polymer.
- The silver ions create a surface within the polymer that is efficient in impeding the build-up of microbes and bacteria, making the material antimicrobial.
- These ions do not deplete when the inhibition process takes place, which allows the antimicrobial effect to stay in place.
- These products are non-hazardous and are safe for the environment.
Characteristics:
- Compound in powder form that is ready to use for rotational moulding.
- Excellent antibacterial efficacy as well as resistance to algae development.
- Safe: Because it is non-migrating, it is safe for food packaging.
- Low silver loading is sustainable.
- Silver ion emission is slow and modest.
- Silicone silica matrix binds to polymers.
- Substances that is not dangerous
- Silver does not migrate from plastic, making it environmentally friendly.
- Because silver is inorganic, it does not degrade or release toxic substances into the environment during processing or use.
- Easy To Melt
Processing Instructions:
- Molding cycles are determined by the materials used in the mold, as well as the thickness of the mold’s walls, oven temperature, and shot size.
- Temperatures in the oven should be set between 250 and 300 degrees Celsius. The ideal PIAT for Anti-Microbial product is around 215 °C, but this varies depending on the color these powders should be added at the end of a heating cycle, after a PE skin layer has completely melted.
Important Points:
- Flaming the surfaces of molded parts with an open torch is not suggested due to the risk of thermal deterioration and early failure.
- Compounding or dry blending of fillers or recycled materials into resins is not suggested due to the danger of compromising impact strength.
- Because of the possibility of lesser impact strength, dry blending pigments exceeding 0.3 percent into natural powder should be avoided.
- Depending on the final applications, additional antioxidants, internal lubricants, or UV stabilizers should be incorporated into the virgin resins during the compounding process.
- It is not advised for items with a diameter of more than 5 mm or a temperature of more than 30 degrees Fahrenheit.
- It is not suggested for products that are exposed to direct sunlight.
- We cannot guarantee the antibacterial function’s longevity based on customer usage and water quality.

FAQs
What is Antimicrobial Rotomoulding Powder?
Antimicrobial Rotomoulding Powder is a specially formulated polyethylene (PE) powder that contains antimicrobial additives to inhibit the growth of bacteria, fungi, mold, and algae on the surface of molded products. It is commonly used in medical, food storage, and hygiene-sensitive applications.
How does antimicrobial technology work in rotomoulding powder?
The antimicrobial agents in the powder disrupt the growth of microorganisms by:
Silver Ion Technology (Ag⁺) – Silver ions interact with microbial DNA and proteins, preventing reproduction.
Zinc Pyrithione (ZnPT) – Disrupts cell membrane integrity, stopping bacterial growth.
Copper-Based Additives (Cu²⁺) – Destroys bacterial metabolism and replication.
Organic Biocides – Prevent mold and fungi formation.
What are the key technical properties of Antimicrobial Rotomoulding Powder?
| Property | Typical Value | Standard |
| Base Polymer | LLDPE (Linear Low-Density Polyethylene) | – |
| Density | 0.930 – 0.945 g/cm³ | ASTM D792 |
| Melt Flow Index (MFI) | 3-7 g/10 min (190°C, 2.16 kg) | ASTM D1238 |
| UV Stabilizers | HALS (Hindered Amine Light Stabilizers) | – |
