Cosutin Industrial is a main cyclopentane supplier for years. Cyclopentane is used in the manufacture of synthetic resins and rubber adhesives and also as a blowing agent in the manufacture of polyurethane insulating foam, as found in many domestic appliances such as refrigerators and freezers, replacing environmentally
damaging alternatives such as CFC-11 and HCFC-141b. More advanced technologies, such as computer hard drives and outer space equipment employ multiply alkylated cyclopentane (MAC) lubricants because of their extremely low volatility.

Polyacrylamide (PAM) produced by Xinhuan is a water-soluble polymer, insoluble in most organic solvents, with good flocculation effect. According to the different ionic properties, it can be divided into three major types: anionic, cationic and nonionic. In neutral alkaline media, it is characterised by polymer electrolytes, sensitive to salt electrolytes, and crosslinked with high-valent metal ions to form insoluble gels.

Product Features
1. Flocculation: PAM can make suspended matter flocculate through electrical neutralization, bridging adsorption.
2. Adhesion: It can act as an adhesive through mechanical, physical and chemical effects.
3. Resistance reduction: PAM can effectively reduce the friction resistance of the fluid. Adding a trace of PAM to water can reduce resistance by 50-80%.
4. Thickening: PAM has a thickening effect under neutral and acidic conditions. When the pH value is above 10, PAM is easily hydrolyzed. When it is a semi-net structure, the thickening will be more obvious.

Poly Aluminium Chloride (PAC) is an advanced inorganic polymeric water treatment agent. It exhibits strong flocculating and adsorbing properties, making it effective in removing suspended particles, colloids, and some dissolved substances from water. PAC is widely used in drinking water, industrial water purification, and sewage treatment due to its high efficiency and ease of use.
