Fluorine Free PPA
Standard PPA made from fluoroelastomers used for enhancing processability of various polymers, mostly used in PE and PP processing. Evonik TEGOMER additives based on organo-modified siloxane (OMS) technology is the best alternative to conventional additive technologies.
Organo-modified siloxanes delivered on a polymer carrier to be used directly on the converting line
Dosage: 0.5 – 2.0% as PPA
Features
2-in-1 approach: PPA + permanent slip enhancer, e.g. in films
• Replacement of fluoroelastomer MB
• Suitable for transparent and matt films
• Excellent “shark skin” prevention in blown, cast and BOPP films
• Die built-up prevention, even in highly-filled CaCO3 films
• Significant reduction of the coefficient of friction (COF) and strong permanent slip enhancement
• High throughput
• No settling on metal parts, therefore a shorter start and run-up phase which results in reduction of production waste
• Allows fast color/recipe changes
• No VOC, no migration and no corrosive degradation products
