In the formulation, the main functions of surfactants are: one is to improve the emulsifying ability between the components, so that they can be more effectively mixed with each other; the other is to control the system to have proper surface tension during the foaming process to produce a good Bubble network structure, therefore, can also be called foam stabilizer. Polyester and polyether flexible foam have different raw material bases and different properties. Therefore, the selection and dosa ...

Silicone oil, as a common ingredient in cosmetics and skin care products, has a "false slippery" effect compared to hair care products. There are more types of silicone oil in cosmetics and skin care products, and its effects on the skin are also more amazing.About Silicone OilSilicone oil is also translated as silicium, because its structure is stable, non-toxic, not prone to degradation and not prone to chemical reaction with other products, so it is now more and more used in various ...

Curing is usually accomplished by condensation of silanols to form siloxanes. When the condensation reaction is in progress, due to the gradual decrease of the silanol concentration, the steric hindrance is increased, and the fluidity is poor, resulting in a decrease in the reaction rate. Therefore, in order to fully cure the resin, the reaction must be accelerated by heating and adding a catalyst. Many substances can catalyze the silanol condensation reaction, including acids and bases, soluble ...

Dear Customer:Thank you for your support and trust!

The full name of polyurethane foaming agent is one-component polyurethane foam jointing agent, commonly known as foaming agent, foaming glue, PU jointing agent, English PU FOAM is the product of aerosol technology and polyurethane foam technology cross combination. It is a special polyurethane product in which components such as polyurethane prepolymer, blowing agent, and catalyst are filled in a pressure-resistant aerosol can. When the material is sprayed from the aerosol tank, the foam-like po ...

waterproofing agentSilicone waterproofing agent is a new type of high-efficiency waterproofing material without pollution and irritation, which is widely used in advanced countries in the world. After this product is sprayed (or brushed) on the surface of the building, a colorless, transparent, UV-resistant, breathable film can be formed on the surface of the building, which is imperceptible to the naked eye. When rain blows on it or encounters moist air, the water droplets will be natural. Flow ...

Coupling agent is an important treatment agent with a wide range of applications, mainly used as an auxiliary agent for polymer composite materials. The biggest feature of the molecular structure of the coupling agent is that the molecule contains two groups with different chemical properties. Synthetic resins or other polymers undergo chemical reactions or generate hydrogen bonds to dissolve them. Therefore, coupling agents are called "molecular bridges" to improve the interface betwe ...
