Features and Advantages

1. Efficient surfactant may be a candidate for consideration in hydrocarbon blown foams especially, such as in refrigerators and cool-store applications. The typical use level is 2.0 to 3.0 parts per hundred of polyol (php).

2. Provides extremely fine cells and therefore low thermal conductivity with cyclopentane as well as mixture of cyclopentane and other hydrocarbons or hydrofluorocarbons.

3. Deliver as well, good foam flow, even density distribution and reduced void formation.

4. The combined effect on fine cells and flow delivers foam with consistently low thermal conductivities throughout the foam.


Silicone Foam Stabilizer RJ-F1600 is available in 200kg iron drum.


This product should be stored in a cool and dry place, away from fire and heat source. This product will be turbid and even solidified at low temperature. No impact on performance and usage. Heated to around 30 ℃ can restore transparency.

Shelf life

12 months of storage period or longer if the test is qualified to continue to use.
