PBTCA is widely used in the formulation of efficient scale and corrosion inhibitors and is one of the best performing products. It is also an excellent stabilizer for zinc salts. Widely used as a corrosion and scale inhibitor in circulating cooling water systems and oilfield water injection systems, it is particularly suitable for use in combination with zinc salts and copolymers. It can be used in high temperature, high hardness, high alkalinity, and situations that require high concentration ratios. PBTCA can be used as a chelating agent and metal cleaning agent in the washing industry. PBTCA is generally used in combination with other water treatment agents such as zinc salts, copolymers, organic phosphines, and azoles; If used alone, the dosage is 5-15mg/L.

HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330�ºC. HPMA has obvious threshold effect under high temperature (350�ºC) and high pH(8.3)level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300�ºC with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement.

Metal tin is mainly used in the manufacture of alloys.
Tin and sulfur compounds - tin sulfide, which is similar in color to gold, is commonly used as a gold pigment.
Tin's modern application is as a solder for the electronics industry. Used in various purities and alloys (often with lead or indium), tin solders have a low melting point, which makes them suitable for bonding materials.
