Technical Information
General
d2p contains a sparingly-soluble silver-containing salt which provides a slow release of silver ions, safely inhibiting bacterial and fungi growth.
The slow release of the silver active-ingredient gives the products within the plastic products long-term protection.
d2p can be used with d2w. The oxidation phase will not be affected but the biodegradation process of the plastic product may substantially retard or cease entirely.
Temperature
d2p additives can be processed at temperatures up to 600°C without losing their anti-bacterial properties.
Physical Properties
| Appearance: |
White pellets |
| Particle-size and shape: |
2-3 mm cylindrical |
| Solubility: |
Essentially insoluble |
Recommended Addition Rates
The target recommended inclusion rate for d2p is between 1% and 2% depending on applications and conditions.
Storage
Whilst d2p products have been formulated to have maximum stability in storage and in use it should be understood that silver-containing materials do exhibit varying degrees of light-sensitivity and can cause discoloration in the finished article.
It is therefore incumbent upon the user of the d2p products to evaluate them fully under their normal conditions of use.
d2p products should ideally be used within 6 months of purchase.
d2p Anti-microbial in Polymers
d2p additive has successfully been incorporated into the
following polymers:
Product Description
d2p is an additive system that provides anti-microbial and fungicidal performance.
d2p is an anti-microbial masterbatch designed for specific applications. The inorganic nature, small particle-size and high temperature-tolerance of the active ingredient makes it ideal for use in a wide range of polymer processes.
How Does It Work?…Silver Based Biocide
Silver is widely accepted as having broad-spectrum anti-microbial activity. In order to understand why this is so, it is necessary to examine the action of silver ions against microbes.

d2p a Successful Protection Against Micro-organisms
d2p is active on micro-organisms including:
- Methicillin-resistant Staphylococcus aureus (MRSA)
- Canida Albicans
- Aspergillus niger
- E-coli
- PS.Aeruginosa
- Sal.Enteritidis
- Kl. Pheumoniae
- Pe.Funiculosum
- Str.Mutans
- B cecrus
Key Benefits of Using d2p - Design to Protect Against
- Cross contamination
- Healthcare and food industries infections
- Staining
