SD2602

Blend Polyol for making rigid polyurethane foam used for waterborne floating body system

Description

SD2602 formulated polyol is a kind of pouring polyurethane rigid foam system designed with the HCFC-141B system. It is specially used for the waterborne floating body system. It contains all the raw materials and auxiliaries necessary for the production of rigid polyurethane foam including the blowing agent. It has the characteristics as following:

n  Light weight and strong buoyancy.

n  Good dimensional stability.

n  Small water absorption and long service life in the water.

Applications

This product is suitable used for waterborne floating body system, it is can be widely used for the filling of waterborne floating body system

Dimensional Stability（﹢70～-30℃，48h）%	≤3
Compressive Strength  kPa	≥160
Water Absorption（v/v）	≤4

Remark:  Above data is obtained by the lab testing, actual data at customer side may be different because of test machine and condition, etc. And all the data listed of our products will have no any legal force.

Packaging： 

The material is normally supplied in iron pail with Zinc coating in standard container, 220kgs/drum.

Storage Recommendations：

The SD2602 is hygroscopic and containers must be kept sealed tightly to prevent absorption of moisture, which can adversely affect processing. During the transportation, it should avoid serious shake and strong sunlight. It should be stored in ventilated place, avoiding light, water and fire. Recommended storage temperature is 10～25℃.
