Silicone surfactant
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.
JSY-1000---for CRC-11 blowned
blown Rigid Polyurethane Foam¡¡
It has good emulsification, and the system had good stability.
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.
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.

JSOT-11 Polyurethane Foam
Depressant
JSOT-11 is extensively used in polyurethane systems. (including
polyurethane elastomer, monocomponent moisture-curable and
two-component polyurethane coating, sealants, and adhesives
etc.) This product reacts with water (of moisture) in system
to form active groups first, and then cross-link with isocyanate.
So by using JSOT-11, the problem of traditional monocomponet
system that the system don't foam during curing will be
easily solved. As a result, gluing cure will be quicker,
storage stability will be better, and the quality of the
polyurethane elastomer will be higher.
Physical properties
JSOT-11 is a kind of primrose, stringy, transparent liquid.
When the environment temperature is about 20¡æ, the degree
of viscosity is 2500-3000 cp.
Features
JSOT-11 can :
* easily be dissolved in other
components of the polyurethane
* keep clarity of the original
system.
* Increase polyurethane system's
storage life up to six months.
Usages
In addition to its usage as foam depressant, this product
can also be used as
