※MSDS Download ※TDS Download Inquiry


Silicone Stabilizer RJ-F1801 is a medium potency, alkyl-pendant, organosilicone surfactant for use in flexible slabstock foam applications that require the use of flame retardants. Use of this surfactant may minimize the amount of flame retardant required to pass combustibility tests.

Technical Index

Appearance  Clear liquid
Viscosity at 25℃,cSt  500-800
Specific gravity,25℃  1.03
Flash piont,pensky-martens closed cup,℃  103
Water,%  ≤0.3

Features and Advantages

1. Excellent processing on all types of foam equipment

2. Wide foam processing latitude

3. Very broad grade range latitude

4. The density gradient of product is small

5. Can increase the flame retardant effect of foam, or reduce the dosage of flame retardant in the same flame retardant effect. In the appropriate formulation, the production foam can meet the BS5852 standard.


Silicone Stabilizer RJ-F1801 is available in 200kg iron drum or 1000kg plastic 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.
