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
