Polyurethane foam depressant
Across all of Polyurethane foam applications there is great
need of surfactant for the vital properties of stabilization,
nucleation, and emulsification. Our products have been specifically
designed for the different technologies targeting the necessary
requirements. For Rigid applications we offer recommendations
based on extensive research with the blowing agents being used
today. For flexible foam we provide HR foam stabilizer surfactants
that cover low to high-density applications. We also offer a
product designed for micro cellular foam used in shoe sole.
Options
JSY-168---for micro cellular PU shoe-sole
foam
It is provided with better hydrophilicity, which can make the
foam system emulsified uniformly. The foam products will have
enough open cells and regular uniform cells.
The use level of JSY-168 is suggested to be 5¡«8 (parts on 1000
parts polyol)
JSY-1000---for CRC-11 blown Rigid Polyurethane
Foam¡¡
It has good emulsification, and the system has good stability.
The use level of JSY-2000 is suggested to be 1.5¡«2.5( parts
on 100 parts polyol ).
JSY-2000---for CRC-free PUR¡¡
It is a non-hydrolytic polyether-polysiloxane copolymer. It
is fit for rigid polyurethane foams blown with cyclo-pentane,
HCFC-141b and other alkane blowing agents. This product possesses
advantages such as good emulsification, excellent nucleation,
and good stability, etc.
The use level of JSY-2000 is suggested to be 1.5¡«2.5( parts
on 100 parts polyol ).
JSY-6504,JSY-6505---for HR molding PU
foam¡¡
With much improved properties such as lower activity and wider
processing range, it can enhance the compatibility in HR systems
and improve the cell structure of the foam. The prepared foams
have more open-cell rate, and the pores are fine and dense.
The resiliency of the foams is high. JSY£6505 is more suitable
for the lower-density foam and application in large-block PU
foam.
The use level of JSY-6504 is suggested to be 0.8¡«1.5 (parts
on 100parts polyol)
