5. Antimicrobial Masterbatches
Biocidal & Biostatic in action
Very stable as Silver ions are held and released from a glass matrix
Easy to dose as the glass matrix is well dispersed in all preparations
High degree of efficacy
Controlled and sustained release of Silver ions gives consistent performance over a long period of time
Silver ions remain stored in the polymer and are gradually made available as the surface is abraded microscopically

6. How does BactiglasTM work?

7. BactiglasTM Long lasting protection
European & FDA food contact approvals
Tested using the international ISO standard
Suitable for many polymers and plastic processes:
Moulding
Profile Extrusion
Fiber
Film & sheet
Many diverse applications:
Home & Industrial Hygiene
Medical devices
Pharmaceutical packaging

9. ReverteTM Oxo-biodegradables
ReverteTM is an ‘oxo-biodegradable additive’ masterbatch
Added to standard Polyolefins at 1% by weight
ReverteTM will makes ordinary plastic degrade in the environment at the end of its useful life
ReverteTM requires no special processing conditions and has little effect on physical properties

10. How ReverteTM Works
Polyethylene and Polypropylene normally degrades very slowly in the open environment due to:
High molecular weight (approximately 250,000)
Hydrophobic surface
ReverteTM rapidly accelerates the oxidative breakdown reducing the molecular weight
The low molecular weight species can then be biodigested by microbes in the environment
