※MSDS Download ※TDS Download Inquiry

Description

Foam Stabilizer RJ-H1602 is a non-hydrolizable silicone copolymer that may be considered for use in the manufacturing of rigid polyurethane foams. It is an excellent candidate for hydrocarbons blown polyurethane foams used in appliances and in the construction industry. However, the experience has demonstrated its suitability as general-purpose surfactant for other rigid foam applications and with different blowing agents. 

Technical Index

Appearance  Clear, Pale Yellow Liquid
Viscosity at 25℃,cSt  700-1000
Specific gravity,25℃  1.03
Flash piont,pensky-martens closed cup,℃  93
Water,%  ≤0.3

Features and Advantages

1. Suitable for use in systems for refrigeration, lamination and pour in place foam applications, using hydrocarbons as blowing agents and co-blown with water.

2. Provides good solubility of cyclo-pentane and cyclo/iso-pentane mixtures in the typical polyol formulations used in the appliances industry.

3. Delivers extremely fine celled foams, thus obtaining foams with very good thermal insulation performance.                                 

4. Stabilization of foam growth in pour-in-place applications, in systems using water and HCFC 141b as blowing agents as well as HFCs or HFOs

5. The common level range is 1.5 to 2.5 parts per hundred of polyol (php)

Packing

Foam Stabilizer RJ-H1602 is available in 200kg iron drum. 

Storage

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.
