- Product Applications
- A major field of application for mineral-filled compounds is the cable industry.
- EPDM and EVA can be processed into highly filled cable compounds through the adhesion promoting and hydrophobising effect of Dynasylan® 6490.
- The EPDM and EVA polymers with Dynasylan® 6490 are for the halogen-free, non-toxic, environmentally-friendly flame retardant cable compounds (HFFR) based on ATH and MDH.
- In addition, Dynasylan® 6490 can be used in many other applications such as filler and pigment coating, dispersions etc.
Properties
- Physical Form
- Product Reactivity
- Dynasylan® 6490 is excellent as an adhesion promoter, dispersion and hydrophobation agent in mineral filled compounds.
- In the presence of moisture, the methoxy groups of Dynasylan®6490 hydrolyse to produce methanol and reactive silanol groups.
- These silanol groups react with the filler via silicon oxygen bridges.
- The vinyl functional groups of Dynasylan® 6490 react with the polymer phase in the presence of radicals.
