We manufacture polyurethane raw material including polycarbonate-diol,
polyoxyalkylene amines, aromatic polyester polyol, etc.
Polycarbonate-diol (PCDL)
Polycarbonatediol£¨PCDL£©is one of polyols used in the new
generation synthesized polycarbonate-based polyurethane.
Polyurethane produced from PCDL is superior to the ones
from polyether-diols or polyester-diol in mechanical performance,
heat resistance, oil resistance, hydrolytic resistance,
oxidizing resistance, abrasion resistance, chemical resistance
and weather resistance. PCDL performs pretty excellent with
respect to hydrolytic resistance and aging resistance, its
outstanding synthetic properties enables various applications
in each area of polyurethane.

Polyoxyalkylene Amines
Polyoxyalkylene amines is a kind of polyoxyalkylene compound
edge sealed by amino-group, mainly used in polyurea spray
elastomer, RIM product, epoxy resin curing agent and fuel
additive.
Features
Polyoxyalkylene amine has much superiority. Compare with
other amine group curing agents, polyoxyalkylene amines
has :
* low viscosity, light color,
easy soluble in many organic chemicals, suitable reaction
active,
* Polyurea spray elastomer
made from polyoxyalkylene amines has high hardness, excellent
extension, extraordinary properties of abrasion resistant,
and anticorrosion and extended durability. So that they
can be widely used in waterproof, antisepsis, abrasion resistant
coating of concrete and steel construction surfaces, also
provides protection and decoration for some other occasions.
Usages
In addition to its applications in Polyurea spray elastomer,
it can also be used in paint, sealant, textile auxiliary,
building materials, composite materials and adhesive, etc.

Aromatic Polyester Polyol
Aromatic polyester polyol application in Polyurethane foam
system can largely improve the cell structure, plasticity
and tenacity of the foam.
Usages
Automotive roof-trimming
The application of Rigid Polyurethane foam in car roof trimming
facing rapid development with the growing demand in automotive
industry. The use of Aromatic polyester polyol in the system
can improve greatly the thermo-formability, tenacity, buckling-resistance
of roof-trimming PUR materials. So that the cured products
have much higher quality.
PU panels
The existence of benzene ring in the molar structure of
Aromatic polyester polyol can provide the PU panel material
with much better heat-insulation and flame proofing properties.
Heat-insulation applications
In Refrigerator PU system, Aromatic polyester polyol can
help solve the problem that adhesion of PU foam to Refrigerator
base parts lowers in winter, as it can improve the tenacity
and plasticity of PU foam system. Thus the quality of Refrigerator
will be improved.
In water heaters, Aromatic polyester polyol can improve
the sound-insulation, heat-insulation and flameproof properties.
Others
By adding 20%~60% Aromatic polyester polyol to other PUR
foam, the cured products can have much higher plasticity,
tenacity and heat-insulation, much better cell structure,
thus the use of Leveling foamer will be reduced.
It can also be used in flexible PU foam, elastomer, semi-rigid
PU foam, coating, and adhesive to better their properties.
lymer. 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 ).
