Product details
1 PROPERTIES:LOW-MEDIUM OF HARDNESS.
2 PURPOSE: APPLICATION IN PRODUCING FOR SAFETY SHOES WITH DOUBLE DENSITY.
3 Properties of PU resin:
Name of articles Apperance Viscosity(pa.s/40ºC) Density(g.cm³/40ºC)
A-808 Liquid or waxy 1100-1450 1.16-1.19
B-8650 Transparency without any impurity 300-600 1.19-1.22
4 Catalysts and auxiliary agents
* Addtion of water depends on adjusting of product's density and types,generally,outsole(20-
50g/barrel),insole(50-80g/barrel) 
* Generally,for Catalysts,its addition,outsole(300±20g/18kg),but urually depends on mould cavity and demoulding time.

* Based on the best-suitable proportions,which will be changed with the different addition of typical accessory ingredients.
* Free foaming density will be changed according to the changing of seasons,temperature and humidity.
* Demoulding time will be longer than ever with the increased thickness of finished products.
* The above mentioned only for reference,but for other more elements,please test their applicability before using,such as formula,manufacturing technique,applications and so on,otherwise,we have no responsibility for these.
