Pipe Used Blend Polyol

SD2102 two-step method pipeline
This product is suitable used for the pipeline insulation of two-step method. It also can be widely used for the insulation of the Heat-Supply Pipeline, Central air-conditioning pipe, oil pipeline, gas pipeline, medical industry pipeline and so on.

Description

SD2102 formulated polyol is a kind of pouring polyurethane rigid foam system designed with HCFC-141B as blowing agent. It is specially used for the two-step pipeline insulation. 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 The destiny is uniform distribution. It has strong bonding force with other substrates.

n The light weight, high strength and good supporting performance.

n The low thermal conductivity, low water absorption, good dimensional stability.

n The long service life, convenient and fast construction

 

Applications

This product is suitable used for the pipeline insulation of two-step method. It also can be widely used for the insulation of the Heat-Supply Pipeline, Central air-conditioning pipe, oil pipeline, gas pipeline, medical industry pipeline and so on.

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 SD2102 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 1025℃.
