Exhibitor profile

Company profile

Shandong Taihe Technologies Co., Ltd. develops and produces fine chemicals and has more than 20 years of experience exporting electronic chemicals to Japan. The company applies its chemical R&D and production capabilities to electronic-chemical requirements associated with semiconductor manufacturing. Its development model includes joint work with customers on electronic chemicals and customized R&D for application-specific chemical formulations. Laboratory development is supported by analytical and testing equipment used to evaluate chemical properties and application performance. The broader product platform covers phosphonates and their salts, polycarboxylic polymers, biodegradable scale and corrosion inhibitors, biocides, formulated water-treatment chemicals, corrosion inhibitors, reverse-osmosis chemicals, and related fine chemicals. This combination of fine-chemical production, formulation, analytical testing, and customer-specific R&D provides the manufacturing base for both industrial water-treatment chemicals and electronic-chemical development.

Exhibitor profile

Exhibits

The water-treatment chemical range includes phosphonates such as HEDP, PBTC, ATMP, DTPMPA, and HPAA for scale and corrosion control. Phosphonate salts in the portfolio include HEDPNa4 tetra sodium salt, DTPMPNa7 hepta sodium salt, and HMDTMPA K6 potassium salt. Polymer products include PAA or PAAS, HPMA, PMA, AA/AMPS copolymer, and MA-AA copolymer for dispersing and scale-control applications. Biodegradable scale and corrosion inhibitors include PESA and PASP, while biocides include DDBAC or BKC, CMIT/MIT, glutaraldehyde, and THPS. The company also supplies formulated scale and corrosion inhibitors, corrosion inhibitors, reverse-osmosis chemicals, and other water-treatment formulations for industrial systems. HEDPNa4 is the tetra-sodium salt of HEDP and is identified by formula C2H4O7P2Na4 with molecular weight 294. HEDPNa4 specifications include CAS 29329-71-3 for x-Na material and CAS 3794-83-0 for the tetra-sodium form. HEDPNa4 acts as a calcium-carbonate scale inhibitor and is used in low-pressure boilers, circulating-water systems, cleaning applications, and swimming-pool water treatment. The solid product is described as a white powder that is soluble in water and hygroscopic, and HEDP salts can form stable complexes with metal ions including iron, copper, and zinc. The chemistry can dissolve oxide deposits and is described as retaining scale-control function under temperatures up to 250 degrees C. Industrial uses include circulating cooling water, medium- and low-pressure boilers, oil-field pipelines, and systems in power, chemical, metallurgy, and fertilizer industries. Additional uses listed for HEDPNa4 include detergent formulations, hydrogen-peroxide stabilization, dye fixing, and chelation in non-cyanide electroplating. Listed liquid specifications include HEDP content of 20.3 to 21.7 percent and HEDPNa4 content of 29 to 31 percent, while listed solid specifications include 60 percent HEDP and 85 percent HEDPNa4. PASP has a listed molecular-weight range of 1,000 to 5,000 and contains amide and carboxyl functional groups in a biodegradable polymer structure. It is used as a dispersant and scale and corrosion inhibitor in industrial water treatment, boiler water, reverse osmosis, oil-field recycled water, and desalination systems. PASP is presented for high-hardness, high-alkalinity, high-pH, and high-concentration water conditions. Scale-control targets include calcium carbonate, calcium sulfate, barium sulfate, and calcium phosphate deposits. The listed liquid form has 40 percent content with density 1.20 and pH 9 to 11, and a solid form is also supplied. Agricultural use includes increasing urea utilization efficiency by a listed 20 to 40 percent and supporting a listed granulation rate of 97 percent. Other listed PASP applications include soil treatment involving heavy metals, oil-field corrosion control and viscosity reduction, and detergent formulations. In an oil-field application, a 0.4 percent PASP level is associated with more than 70 percent viscosity reduction. PESA is a phosphorus-free and nitrogen-free biodegradable scale and corrosion inhibitor with CAS numbers 51274-37-4 and 109578-44-1. Its listed molecular-weight range is 400 to 1,500, and it is designed for scale control under high-alkalinity, high-hardness, high-pH, and high-concentration conditions. PESA targets calcium carbonate, calcium sulfate, calcium fluoride, and silica scaling while also providing corrosion-control and biodegradability characteristics. The listed liquid product contains 40 percent active material with pH 10 to 12, while the listed solid product contains 90 percent active material. Applications include oil-field refill water and crude-oil dehydration, boiler systems, and circulating-water systems in steel, petrochemical, power, and pharmaceutical plants. PESA is also used in desalination, membrane systems, and detergent formulations. Its combination of non-phosphorus and non-nitrogen chemistry with biodegradability is used where water-treatment programs seek scale and corrosion control without those nutrient elements. CMIT/MIT is an isothiazolinone biocide mixture whose product information lists CAS 26172-55-4 and 2682-20-4 and molecular weight 115.16. The mixture is used to inhibit ordinary bacteria, fungi, and algae and is described as providing rapid microbial inhibition. Application fields include industrial circulating cooling water, wastewater treatment, oil-field systems, papermaking, pesticides, cutting oils, leather, detergents, and cosmetics. The product is available in 2 percent, 4 percent, 8 percent, and customer-specified concentration forms. Listed specifications include a Grade I active-content range of 14 to 15 percent and a Grade II active-content level of at least 2 percent. For sludge-stripping treatment, the listed dosage is 150 to 300 ppm, while routine biocidal dosing is listed at 80 to 100 ppm every 3 to 7 days. Industrial fungicide applications are listed at 0.05 to 0.4 percent depending on the formulation and use case. DDBAC or BKC benzalkonium chloride is another named biocide in the company portfolio and is listed alongside CMIT/MIT and other microbial-control products. The AA/AMPS copolymer is part of the polymeric scale-control and dispersant range, connecting acrylic-acid chemistry with AMPS functionality for water-treatment formulations. DTPMPNa7 and HMDTMPA K6 extend the phosphonate-salt range alongside HEDPNa4 for applications requiring soluble phosphonate forms. The wider catalogue also includes dedicated reverse-osmosis treatment chemicals and formulated scale and corrosion inhibitors rather than relying only on single active ingredients. For semiconductor and electronic-chemical customers, the same fine-chemical R&D organization can perform customized development and analytical verification when a formulation requires application-specific adjustment. Across these exhibits, the supply scope covers individual active ingredients, salts and polymers, biodegradable alternatives, microbial-control agents, and formulated treatment programs for water, process, membrane, and industrial systems.
