LOW PRESSURE SOLAR ENERGY BLEND POLYOLS Systems

LOW PRESSURE SOLAR ENERGY BLEND POLYOLS Systems
Product Detailed
Low pressure solar energy uses special polyol as main raw material, with special additives to make up of blend polyols

  LOW PRESSURE SOLAR ENERGY BLEND POLYOLS

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,

1Low 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.

3Excellent dimensional stability, cohesiveness and nozzle smoothness.

4Applies to process requirements of low pressure solar energy.
