LR-610 Polymethylsilsesquioxane(PMSQ)
CAS NO: 68554-70-1
Silfluo LR-610 is a series of spherical polymethylsilsesquioxane (PMSQ) micropowders (CAS 68554-70-1) produced by hydrolysis and condensation polymerization of organosilanes, forming a highly crosslinked three-dimensional siloxane network (RSiO₃/₂)n. Active content ≥99% across all grades.
The crosslinked siloxane network is insoluble and non-swelling in organic solvents including alcohols, esters, ketones, and petroleum fractions, and maintains spherical morphology without melting or deformation below 400°C. Five grades are available, differentiated by particle size range and surface treatment; LR-610-1 is a hydrophobic-treated variant of LR-610-2.
Chemical Name: Polymethylsilsesquioxane (PMSQ)
Synonyms: Spherical Silicone Resin Powder, Silicone Microspheres, Light Diffusion Agent
