Antimicrobial masterbatch

Antimicrobial masterbatch is a functional plastic masterbatch, specifically a highly concentrated functional plastic masterbatch in which potent antimicrobial agents—such as silver ions, copper ions, or organic antimicrobial compounds—are uniformly dispersed at high concentrations within a plastic carrier. During the processing of plastic products, this highly concentrated masterbatch is uniformly incorporated into the plastic carrier, thereby imparting enduring antimicrobial properties to the finished article.

  • Colour: Available in transparent, white, and custom colours from the Pantone colour chart, or by sample matching.
  • Suitable Substrates: Common plastic resins including PP, PE, ABS, PS, EVA, TPE, PET, etc. Custom substrates supported.

“Types of Antimicrobial Masterbatch

A Multi-Dimensional Analysis of the Types and Applications of Antibacterial Masterbatches

Copper Antimicrobial Masterbatch

Containing copper ions as the active ingredient, it offers high safety and excellent value for money, making it suitable for food contact and medical products.

Silver-based Antimicrobial Masterbatch

The most representative inorganic antimicrobial agent, centred on silver ions, offering broad-spectrum antimicrobial activity, high efficiency, high-temperature resistance, and excellent safety. However, it carries a higher cost and is suitable for high-end electronics and medical equipment.

Zinc-based Antimicrobial Masterbatch:

Centred on zinc oxide, it exhibits excellent compatibility with plastics and is commonly used as an auxiliary component. It synergises with silver or copper to enhance performance. Suitable for daily chemical and packaging products.

Organic Antimicrobial Masterbatch

Contains organic compounds such as quaternary ammonium salts, offering rapid efficacy. However, its heat resistance and durability typically fall short of inorganic types, making it suitable for short-term applications such as disposable packaging.

Classified by Carrier Type

PP-based antimicrobial masterbatch, PE-based antimicrobial masterbatch, PET-based antimicrobial masterbatch, etc.

Classified by Application

Food-grade antibacterial masterbatch, medical-grade antibacterial masterbatch, electronic-grade antibacterial masterbatch, etc.

FAQS

Q1: What is an antimicrobial masterbatch?

A1: An antimicrobial masterbatch is a plastic masterbatch containing a high concentration of antimicrobial agents. When incorporated during the production of plastic products, it imparts lasting antimicrobial properties to the final article.

Q3: Can it be used in food-contact plastics?

A3: Yes, the food-grade antimicrobial masterbatch we produce complies with FDA 21 CFR 177.2600 and GB 4806.7-2016 standards.

Q5: Does the antibacterial masterbatch affect the mechanical properties of the plastic?

A5: No. Customer feedback indicates that after adding the masterbatch, the tensile strength, impact strength, and elongation at break of the plastic remain unchanged compared to the original material.

Q2: What is copper antimicrobial masterbatch?

A2:It is a type of antimicrobial masterbatch that uses copper ions as the active agent, known for strong and durable antimicrobial performance.

Q4: What is the recommended addition ratio for antimicrobial masterbatch?

A4: Our standard addition ratio for antimicrobial masterbatch is 1%–5%. For high-standard applications such as medical devices, this may be adjusted to 5%–8%. Our technical team will provide a customised ratio solution based on your product type and application requirements.

Q6: Do your antimicrobial masterbatch products comply with international certification standards?

A6: Yes. All our products are certified to ISO 22196 (antimicrobial testing), ASTM E2149 (antimicrobial activity), RoHS, REACH and FDA standards. Certification reports can be provided upon customer request.

Free Color Matching Service

Huashuo is a professional masterbatch factory and supplier with advanced pilot mixing production lines and comprehensive testing laboratories to support formula development and mass production needs. We combine spectrophotometry technology with professional visual assessment to establish a standardized color matching process, providing customers with efficient and stable customized color solutions. Please contact our technical team for exclusive color matching support and sample services.

Provide us with a reference for your desired color—either a physical sample or a selection from our existing color portfolio.
Accepted reference formats include:

  • Masterbatch concentrate
  • Finished product sample
  • Paper swatch
  • Paint sample
  • Pantone® color code
  • Film sample
  • Other material references

Once your sample is received, we perform spectrophotometric analysis to establish an initial formulation for the target color.

Pigment selection is guided by the specific application criteria you provide. To ensure optimal formulation, please share the following details about your finished product:

  • Intended application
  • Base resin type
  • FDA compliance requirements, if applicable
  • Expected service life under sunlight exposure
  • Manufacturing process and typical processing temperatures
  • Part thickness
  • Let-down ratio
  • Acceptable color tolerance range
  • Need for spectrophotometric readings and Delta E tolerance specifications

An initial trial batch is produced and evaluated against the reference sample using both visual inspection and spectrophotometric measurements.

Upon finalizing the color match, we supply the following:

  • Color chip samples
  • Safety Data Sheet (SDS)
  • FDA compliance certificate, if applicable
  • 5–10 lb product sample, upon request
