Polyether modified silicone oil is a unique silicone nonionic surfactant formed by grafting and copolymerization of polyether and dimethylsiloxane.
Basic information
Product name: Polyether modified silicone oil
Materials: Polyether and dimethicone
Type: Silicone nonionic surfactant
Field: Chemistry
Product Introduction
In the production of products, by modifying the number of silicone oil chain nodes or changing the ratio of polyether Eo to Po and changing the number of links and end groups of their chains, various silicone surfactants with different properties can be obtained to meet the needs of various industries.
Uses
1. In the plastic greenhouse industry: it can be added to the plastic as an internal additive for the production of drop-free film greenhouses to prevent fog and improve light transmittance.
2. Used for fabric finishing agent: play a soft role, especially suitable for underwear, bed sheets, towels and other finishing, not only soft, but also absorb water and sweat, comfortable to wear.
3. The leveling agent used for paint and polyurethane slurry can reduce the internal friction and stress of its molecules, so as to play the role of leveling and defoaming.
4. Used to make high-efficiency cutting fluid, high-grade cleaning agent.
5. It is used as a homogenizing agent for foaming of rigid polyurethane system to make the cells fine and uniform.
6. This product is used in the cosmetics industry to make cream products, lubricate the skin, moisturize and anti-wrinkle effect.
7. The pesticide industry is used as a wetting agent for glyphosate to improve the efficacy and reduce public pollution.
8. Polyether modified silicone oil is a key ingredient in the preparation of self-emulsifying defoamer and delayed coking defoamer in the refining industry.
9. Other unfinished new application fields
Performance characteristics
1. It has good lubricity and is suitable for making high-grade cutting fluid.
2. It has lower surface tension and is suitable as an antifogging agent.
3. Better softness characteristics and antistatic properties, suitable for use as fabric softener.
4. Good leveling, suitable for adding a variety of resins (polyurethane resin, paint resin, plastic resin, etc.), can well improve the intermolecular stress of these resins, overcome the shortcomings of these resins themselves, and obtain new properties
5. It has good demulsification and is suitable for oil-water separation in some specific occasions.
6. Application in other new fields. Compared with polydimethylsiloxane, this product can be miscible with water in any proportion, and is also miscible with polar organic solvents such as alcohol, DMF, ether, ester, etc., and partially or completely miscible with non-polar solvents such as toluene and alkanes. Convenient when used.
Usage
When this product is used as a leveling agent, the amount of system addition is 0.1~1%, the content in the immersion liquid or impregnating solution is 1~5% when used as a softener, the amount added in the system is 2.5~5% when used as a cosmetic additive, and the addition amount is determined by reference to other applications between 0.1~10% or through pioneer experiments.
Notes
At high temperature or mixed with acid and alkali substances and the storage period is too long, there is a tendency to increase viscosity and even cross-linking.
Packaging storage
1. This product is packed in 50kg plastic drum and 200 kg galvanized iron drum.
2. Store in a dry, cool place and avoid contact with strong acid, strong alkali, etc.
3. This product is a non-dangerous good and can be transported as general cargo.
