- Applications
- Product Applications
- A major field of application for mineral-filled compounds is the cable industry.
- EPDM and kaolin can be processed into cable compounds through the adhesion promoting and hydrophobic effects of Dynasylan® 6598.
- It can also be used in the manufacture of halogen-free, non-toxic, environmentally friendly flame retardant compounds (HFFR) based on EVA or PE and ATH or MDH.
- In addition, Dynasylan® 6598 can be used in many other applications such as filler and pigment treatment, use in dispersions etc.
Properties
- Physical Form
- Product Properties
- Dynasylan® 6598 is excellent as an adhesion promoter in mineral-filled, peroxide-crosslinked compounds.
- The silicon- functional ethoxy groups of Dynasylan® 6598 hydrolyse in the presence of moisture, which is usually present on the filler surface, forming active silanol groups.
- The condensation of these silanol groups with hydroxyl groups on the filler surface leads to a tight chemical bond between Dynasylan® 6598 and the filler.
- The vinyl functional end of Dynasylan® 6598 can be coupled to the polymer in a further reaction that runs parallel to peroxide crosslinking.
