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

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
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
