Company Overview
BactiglasTM AntibacterialAdditives
ReverteTM Oxo-biodegradables
• Wells Plastics is a UK based bespoke specialist additive masterbatch and compound producer
• Formed in 1984
• Dedicated manufacturing & technical facility to Research, Develop, Manufacture and Support innovative products
Company Overview
• We Add Value to our customers by providing Technical Solutions
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

• Many diverse applications:• Home & Industrial Hygiene• Medical devices• Pharmaceutical packaging
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
