Brand: ZEMSIL

Question 1

What is ZEMSIL FS-150?

Accepted Answer

ZEMSIL FS-150 (Fumed Silica (Hydrophilic), CAS 112945-52-5) is a ZEMSIL® silicone material. ZEMSIL FS-150 is a hydrophilic fumed silica with BET surface area of 150 m²/g, produced by flame hydrolysis of silicon tetrachloride. Amorphous, non-porous primary particles of approximately 14 nm aggregate into chain-like structures. Used as reinforcing filler in silicone elastomers, thickening agent in coatings and adhesives, and flow aid in pharmaceutical and food applications. The 150 m²/g surface area provides moderate reinforcement with lower viscosity impact compared to higher surface area grades.

Question 2

What are the main applications of ZEMSIL FS-150?

Accepted Answer

ZEMSIL FS-150 is used in: Silicone Rubber, Coatings, Adhesives, Pharmaceuticals, Food & Feed, Cosmetics.
