Petro Chemicals 2025-05-21
Chemical composition
It is chemically synthesized from imported high-purity refined raw materials. Erucinamide propyl betaine, also called erucic acid amide propyl betaine, is often used as a self-steering acid diverter in oil and gas fields and used to clean fracturing fluids. It is referred to as erucic acid betaine. It is a viscoelastic surfactant resistant to medium and high temperatures. This product can be used alone or in combination with other products, and its temperature resistance reaches 90℃-130℃.
