VS-NH02 High Pressure Solar Water Heater Blend Polyols
Introduction
VS-NH02 is the pale yellow to brown yellow transparent liquid which is used special polyol as main raw
materials, with special additives to make up of blend polyols.
Features of the products are as follows
1).Low odor and environmental protection, use high activity polyol and odorless catalyst, which can reduce
stimulation to respiratory tract of body, protect our healthy effectively.
2).Good flowability during the reactivity process of blend polyols and isocyanate, the density of the forming
foam distributes uniformity.
3).Excellent dimensional stability, cohesiveness and nozzle smoothness.
4).Applies to process requirements of high pressure solar energy.
