PU
Foaming Resins
2-components PU Foaming Resins
INTRODUCTION:
|
The product applications of 2-component PU
Foaming Resins are quite
extensive.
From insulation materials, shoes
materials,
bionic materials (e.g. PU artificial flowers), furniture,
water-proof materials, to various one-piece PU
objects (e.g.
wood-like bath tub,
PU Integral-skin product) have excellent performances. According to
physical properties,
PU foaming resins
mainly divided into:
Rigid Foam, Semi-rigid foam, Flexible foam,
HR foam, LR foam, and Integral Skin foam, etc. |

CATEGORY:
1. RIGID:
After deformed by external force, end product can't restore original shape.
2. FLEXIBLE:
After deformed by external force,
end product
immediately restore original
shape,
resilience is lower.
3. HIGH RESILIENCE:
After deformed by external force,
end product
immediately restore
original
shape,
resilience is higher.
4.
SEMI RIGID:
After deformed by external force,
end product partly
restore original shape.
5. LOW RESILIENCE:
After deformed by external force,
end product
slowly restore original shape.
6. INTEGRALSKIN: Surface of end foam product forms thick
skin.
HOW TO HANDLE:
Suitably mix 2 components of foaming resin (A component
& B component) by suggested weight ratio then put into
the mold. Waiting for it swells and cures to get end PU
foam object. PU foaming method mainly
divided into 2 kinds, free
foaming and in-mold foaming. Making color products,
colorants should be add into A component first and
adequately mix, then add B component into.
