Product Description
Product Name: OSi HIOSil1098
Chemical Name: Vinylmethylsiloxane Homopolymer
Chemical Formula: C3H10O2Si2
CAS No.: 131298-48-1
Properties
OSi HIOSil 1098 is a vinyl silane concentrate (oligomeric siloxane) containing vinyl and ethoxy groups. A colorless nearly odorless low-viscosity liquid. An excellent compatibilizer between inorganic filler (e.g. kaolin, MDH, ATH) and organic polymers (e.g. EPDM, EVA, PE).
The high boiling point of OSi HIOSil 1098, together with its high flash point, gives it outstanding advantages with respect to safety and handling during processing. From an environmental viewpoint, it should be noted that the amount of released hydrolysis ethanol (VOC) is significantly reduced compared to monomeric vinyl silanes.

Applications
Vinyl Silane Polymer OSi HIOSil 1098 is excellent as an adhesion promoter, dispersion and hydrophobation agent in mineral field compounds. In the presence of moisture, the ethoxy groups of OSi HIOSil 1098 hydrolyze to produce ethanol and reactive silanol groups. These silanol groups react with the filler via silicon-oxygen bridges. The vinyl functional groups of OSi HIOSil 1098 react with the polymer phase in the presence of radicals. 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 hydrophobic effect of OSi1098. The EPDM and EVA polymers with OSi HIOSil 1098 are for the halogen-free, non-toxic, environmentally friendly flame-retardant cable compounds (HFFR) based on ATH and MDH.
In addition, OSi HIOSil 1098 can be used in many other applications such as filler and pigment coating, and dispersions. Typical property improvements obtained by using OSi HIOSil 1098 in filled polymers are:
Improve filler dispersion
Good processability
Increase in maximum filler
significantly reduced water uptake excellent balance between tensile strength and elongation at break at a high level
Improved chemical resistance
Higher impact strength
Higher wear resistance
Strongly reduced tendency to crack under pressure
