Product Description

Characteristics

HJSIL® R110 is a kind of hydrophobic fumed silica, treated with poly-dimethylsiloxane. It’s high purity white colloidal powder.


Properties

  • Thickening and thixotropy:HJSIL provides thickening and thixotropic effects in liquid systems such as polyesters, epoxies, and urethane resins.

  • Reinforcement:Adding HJSIL as a filler material improves various mechanical properties of elastomers, including modulus, elongation at break, tensile strength and tear resistance. HJSIL’s large specific surface area also makes it possible to achieve excellent transparency in elastomers.

  • Anti-settling effects:HJSIL improves the suspension behavior in liquid systems, such as pigmented coatings or resins containing fillers.

  • Anti-caking, effects for improved flow characteristics:Due to a property that makes it behave like ball bearings, HJSIL resists lumping and clogging. It can be used to improve the storage stability of powders that are especially prone to caking. HJSIL can also be used to improve flow characteristics and prevent flow problems

  • Anti-blocking effects:HJSIL is added to film resins to reduce “sticking”. It reduces close contact between film layers

  • Adsorbent:Gaseous, liquid or solid materials can be precipitated or adsorbed on the surface of HJSIL. This serves as an ideal carrier or substrate for active ingredients due to its high specific surface area and inertness in the presence of all chemicals except strong alkalis and hydrofluoric acid

  • Insulation:With its very low solid state conductivity and vast spacing between particles, HJSIL provides excellent electrical and thermal insulation properties
