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

7. BactiglasTM • Long lasting protection • European & FDA food contact approvals • Tested using the international ISO 22196 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. ReverteTMOxo-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
