China Rigid Foam Stabilizer

Superiority:

Item No.: Silibase-2891

Product Name: Rigid Foam Stabilizer

Description

Silibase-2891 is a non-hydrolytic foam stabilizer of polysiloxane polyether copolymer, with a silicon-carbon bond. It is a new modified product which is mainly used in rigid foam of PU plastic.

Typical Data

Appearance: Light yellow to amber transparent liquid

Content of active material: 100％

Viscosity(25°C): 600-1200 cp

 Features

Silibase-2891 has good solubility and stability in the premixed systems containing isocyanate, polyether polyol, blowing agent of fluorocarbon, water, catalyst of amine and organic tin, and fire retardant

Silibase-2891 can significantly reduce or even eliminate the ‘shear line’ phenomenon of plastic products, which helps to improve the insulation effect of refrigerators and freezers, and enhance the bonding strength of the foam and the refrigerator shell

Silibase-2891 is particularly suitable for the foam formulation of low fluoride, can reduce the amount of CFC-11 more than 50%

Because of the above advantages, Silibase-2891 is particular suitable for the production of premixed polyether used in insulation materials of refrigerators and freezer, laminations, insulation pipes and spray.

 How to use

Use levels of 2 to 3 parts Silibase-2891 per 100 parts polyols are suggested. The optimum dosage is determined by the particular foam formulation.

Packing and Storage
