As a new foreign trade service provider driven by both technology transformation and export business, HiSiaddi has established a "1+2+3+4=1" service system and can supply PASP polyaspartic acid sourced directly from multiple well-known original manufacturers.
Equipped with R&D capabilities, HiSiaddi has partnered with factories on technology transfer and conducted multiple rounds of on-site inspections of PASP manufacturers, developing objective and in-depth insights into different brands. We regularly analyze PASP manufacturers for clients to help them select matching products. Below is a brand recommendation case.
For inquiries about brand and model comparative analysis, please contact HiSiaddi customer service.
The buyer is HYDRO SINGAPORE, a high-end water treatment group headquartered in Singapore, specializing in municipal premium water purification, commercial complex recirculating water and semiconductor plant ultrapure water supporting treatment. It serves mid-to-high-end clients across Singapore and five Southeast Asian countries, fully complying with Singapore PUB water standards, EU REACH and ISO 14001 environmental certifications, standing as a benchmark mid-to-high-end water treatment enterprise in Southeast Asia.
The client places an annual order of 30 tons of PASP for RO membrane scale inhibition, recirculating water corrosion protection and water purification chelation, with requirements including low chroma, high purity, low free monomer and biodegradability ≥90%. Having previously sourced exclusively from European suppliers, the client had zero knowledge of China’s PASP brand landscape, technical tiers and model differences upon first switching to Chinese procurement. The four manufacturers contacted only promoted their own brands and avoided horizontal comparisons, leaving the client unable to assess product suitability and stalling procurement. The client formally entrusted HiSiaddi with end-to-end neutral brand research, technical benchmarking, model recommendation and sample verification services.
1. Blank brand awareness with no basis for product selection The client only knew China is the primary PASP producer but could not distinguish mid-high, mid and low-tier brands, lacking understanding of each brand’s technical strength, product positioning and quality stability.
2. Self-promotional manufacturers with no neutral reference The four contacted manufacturers (Taihe, Yuanlian, Xietong, Yousuo) only highlighted their own advantages without mentioning peer strengths or providing horizontal comparisons, preventing objective differentiation and raising risks of suboptimal product selection leading to unqualified water quality or membrane damage.
3. Chaotic model naming complicating parameter matching Disorganized model naming conventions (e.g., Jingyuan, Shuiwei, PASP40) create wide disparities in molecular weight, solid content, chroma and free monomer across brands, hindering rapid matching with the client’s dual RO membrane + recirculating water working conditions.
4. Concerns over quality stability Accustomed to consistent batch performance from European suppliers, the client feared large batch fluctuations, unstable supply of high-end grades and inadequate technical support from Chinese brands, threatening long-term project operation.
Based on industry reputation, technical capacity, high-end client track records and compliance certifications, HiSiaddi screened five mainstream manufacturers (Shandong Taihe, Shandong Yuanlian, Hebei Xietong, Shandong Yousuo, Jiangxi Yizhong) and conducted neutral breakdowns across six dimensions: brand positioning, core technology, mainstream models, key indicators, strengths & weaknesses and applicable scenarios, compiling a detailed benchmark report.
· Positioning: Domestic PASP industry leader, high-end water treatment specialist serving global water treatment and semiconductor clients, export volume accounting for over 40% of total sales.
· Core Technology: Low-temperature polymerization + ion exchange purification delivering narrow molecular weight distribution (PDI <1.2) and low chroma.
· Mainstream Models:
o TH-PASP42 (High-End Water Treatment Grade): Solid content 42%, chroma ≤10 Pt-Co, free monomer ≤0.2%, biodegradability 96%.

· Core Technology: Traditional production processes delivering basic indicators at ultra-low prices.
· Mainstream Model: PASP35 (Agricultural Grade): Solid content 35%, chroma ≥50 Pt-Co.
· Strengths: Ultra-low pricing, fast regional delivery.
· Weaknesses: No high-end grades, no international certifications, severe quality fluctuations.
· Applicable Scenarios: Agriculture, low-end wastewater; excluded for client’s high-end demands.
Combining the client’s dual working conditions (RO membranes requiring low chroma & high purity + recirculating water requiring strong chelation & stability), three low/mid-tier brands were eliminated. Two mid-to-high-end manufacturers and three core models were recommended to balance performance suitability, stability and cost-effectiveness:
1. Shandong Taihe Technology (Top Mid-to-High-End Option)
o Model 1: TH-PASP42 (High-End Water Treatment Grade): Optimized for RO membranes and semiconductor ultrapure water, chroma ≤10 Pt-Co, free monomer ≤0.2%, complete REACH certifications, batch deviation <0.1%, meeting the strictest operating conditions.
o Model 2: TH-PASP35 (General Recirculating Water Grade): Optimized for commercial complex recirculating water, solid content 35%, scale inhibition efficiency ≥98%, highly cost-effective to reduce overall expenditure.
2. Shandong Yuanlian Chemical (Mid-to-High-End Backup, Ultra-High-Purity Advantage)
o Model 3: Jingyuan-42 (High-Purity Phosphorus-Free Grade): Optimized for high-silica high-alkali RO water and water purification chelation, chroma ≤8 Pt-Co, total heavy metals <0.5 mg/kg, 96% biodegradability, excellent stability under extreme water quality conditions.
HiSiaddi submitted a five-brand benchmark report, three-model parameter comparison table, sample test reports and high-end client case studies. The client’s technical team completed review within one week and endorsed HiSiaddi’s neutral, professional and unbiased selection logic. Final procurement plan: 15 tons of Taihe TH-PASP42 for RO membrane systems + 15 tons of Yuanlian Jingyuan-42 for recirculating water and backup use, with dual-brand sourcing securing supply chain resilience.
25kg samples of each of the three models were delivered. Client laboratory testing verified full compliance for chroma, free monomer, biodegradability and membrane compatibility; performance matched European imported products, with superior metrics (heavy metal control, batch consistency) in certain categories.
The 30-ton order was delivered in two batches, each accompanied by full SGS test reports, REACH documentation and Certificates of Analysis with zero quality disputes. The client canceled procurement plans with European suppliers and signed a three-year annual framework agreement with HiSiaddi, raising annual procurement volume to 40 tons and awarding full supply of supporting reverse osmosis scale inhibitors and recirculating water corrosion inhibitors to HiSiaddi.
The client fully resolved three major pain points: ambiguous brand awareness, lack of product selection benchmarks and quality stability worries. The client commented that HiSiaddi “does not merely sell products, but delivers neutral and professional supply chain solutions”, establishing the client as HiSiaddi’s core benchmark partner in Southeast Asia’s water treatment sector.
Overseas mid-to-high-end clients prioritize precise working condition matching, stable quality and compliance assurance over low pricing alone when purchasing PASP. Manufacturers’ self-promotional sales models fail to meet demand for neutral product selection. Leveraging full industry visibility, independent research capabilities, technical benchmarking expertise and unbiased recommendation logic, HiSiaddi helps clients navigate fragmented brand landscapes to accurately identify suitable mid-to-high-end brands and models, balancing quality assurance and cost optimization. This constitutes the core value of HiSiaddi as a procurement partner for overseas mid-to-high-end chemical products.
