HB-135
Characteristics
HB-135 is hydrophobic fumed silica which is produced by HL-380 after chemical post-treatment with HMDS (Hexamethyldisilazane).
Applications
Silicone rubber
Adhesives and Sealants
Defoamer
Toner
Properties
Low thickening effect and excellent processability enable high loading in polymers
Excellent reinforcing properties in silicone rubber especially at high filler loading levels(RTV-1,RTV-2,LSR)
Good transparency performance
Free-flow aid for powders
