Dynasylan® 6490 is a vinyl silane concentrate (oligomeric siloxane) containing vinyl and methoxy groups.
Scope of Application
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. typical property improvements obtained by using Dynasylan® 6490 in filled polymers are:
improved filler dispersion
good processability significantly
excellent balance between tensile strength and elongation at break at a high level
improved chemical resistance
strongly reduced tendency to stress cracking
higher impact strength
higher abrasion resistance
