H-3602 FOAM STABILIZER
H-3602 foam stabilizer is a kind of silicon-carbon bond based non-hydrolytic
copolymer of polysiloxane and polyether. It is suitable for most conventional rigid
polyurethane foam systems, it has wide use range, for example cyclopentane, HCFC-
141b, 134a and high-water content foaming system. H-3602 is applied for premixed
polyols used in refrigerators, freezers, PU panel, spraying foams etc.
? It has excellent compatibility and emulsification ability with polyether polyols and
outstanding surface activity;
? it has strong nucleation ability and stabilizing foam ability，it gives very fine cell
structure, and high rate of closed cells;
? it produces good flowability, and it can obviously be reduced or even eliminated
the large voids under foam surface, supper insulation and homogeneous density
? it let polyurethane foam obtain superior adhesive strength with mold.
