Specifications
High Pressure Solar Energy Polyurethane Blend Polyols
· DTY-202HP
Product Introduction
This product uses special polyol as main raw material, with special additives to make up of blend polyols, which characteristics are as follows,
1,Low smell 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.
