Softener application

Generally required to be light, odorless, non-toxic, low in volatility and chemically stable. Textiles can be sulfonated oils, high-carbon fatty acid emulsions and silicone oils to reduce their rough feel and plump. Leather can be used for animal fats (such as butter, fish oil), vegetable oils (such as castor oil), petroleum products (such as spindle oil, paraffin, asphalt), sulfonated oils (such as sulfonated fish oil, sulfonated castor oil), and birch bark The product after tar and oil refining, etc., to make it softer and fuller, and to reduce its hygroscopicity. Paper can be used to increase the flexibility of the melamine, and some paper fillers such as white clay also have a softening effect.


Softener is an additive used to improve the processing property and performance of rubber. It can increase the plasticity of the rubber compound, reduce the viscosity of the rubber compound and the temperature during mixing, improve the dispersibility and mixing, and improve the stretching of the vulcanized rubber. Strength, elongation and wear resistance. Softeners are similar in function to plasticizers, except that plasticizers are chemically synthesized and used primarily in resins and plastics, while softeners are mostly derived from natural materials and are used almost exclusively in rubber.


Softeners are foaming additives that have a softening effect at higher levels of chemical blowing agent water. It is generally achieved by reducing the amount of isocyanate and the hardness of the foam. They are basically used in low index formulations, soluble in water, can use more water and less blowing agent in the formulation or completely eliminate the physical blowing agent) to achieve the desired foam hardness.
