Client: AgrarTech GmbH, Germany (referred to as Company A) Industry Positioning: Top European manufacturer of agricultural film and horticultural materials specializing in high-end PO greenhouse films, long-term weather-resistant mulch films and special protective films for flowers. Its products are supplied to global seed industry giants including Bayer Germany and Rijk Zwaan Netherlands, covering high-end agricultural markets across the EU. The company imposes extremely stringent requirements on auxiliary purity, thermal stability, extraction resistance, low blooming and batch consistency, and rejects low-end general-grade products. It previously purchased BASF Chimassorb 2020 for a long time, but turned to China for customized HALS-2020 solutions urgently due to tight European production capacity, a 12-week lead time and a 25% price hike.
1. Low alkalinity customization: pH value controlled at 8.0–8.5 (general grade: 9.0–10.0), to avoid yellowing and blooming caused by reactions with acidic antioxidants (e.g. 1010) in films.
2. Narrow molecular weight distribution: Molecular weight ranging from 2800 to 3200 with distribution coefficient <1.3 (general grade: <1.5), improving hot water extraction resistance (retention rate ≥92% after 100h boiling in 95℃ water).
3. Ultra-low volatile matter: ≤0.2% (general grade: ≤0.5%), suitable for high-temperature extrusion at 230℃ without die buildup or odor.
4. Low organochlorine residue: ≤50ppm (general grade: ≤200ppm), complying with EU Regulation EC 1907/2006 (REACH) and eco-label requirements for agricultural films.
5. Customized pellet form: Uniform cylindrical pellets of 2–3mm (general grade: powder or irregular flakes), reducing dust generation, improving compatibility with PE resin and lowering screw wear of extruders.
The client contacted three mainstream Chinese HALS-2020 manufacturers (Lusheng, Lianlong, Jiadejia), all of whom stated mass production was only available for general-grade products and failed to meet customized specifications. The issues included uncontrollable low pH, broad molecular weight distribution or excessive organochlorine content. Besides, manufacturers showed little willingness to accept small-batch customization (monthly demand of 3 tons) and could not guarantee delivery schedules. Company A’s customized project was nearly suspended, threatening the launch schedule of its new high-end film products.
With 8 years of in-depth experience in customized foreign trade of polymer additives and a focus on mid-to-high-end clients, HiSiaddi collaborates with the R&D team of Jiangsu Lusheng, China’s leading HALS-2020 producer. It boasts capabilities in customized solution design, lab trial sampling, pilot-scale mass production and full-process technical tracking, excelling at solving challenging niche customization demands with strict indicators for mid-to-high-end clients.
HiSiaddi’s technical team held in-depth communication with Company A’s R&D director to verify the feasibility of each customized indicator and sort out three core technical bottlenecks:
1. Difficult low alkalinity control: Unreacted residual piperidine amine in synthesized general-grade HALS-2020 leads to high pH; optimized end-capping reaction processes are required to reduce free amine residues.
2. Difficulty achieving narrow molecular weight distribution: Molecular weight polarization easily occurs during polymerization; precise control of reaction temperature, dropping rate and catalyst dosage is needed to stabilize polymerization.
3. Challenge of lowering organochlorine residue: Trace chlorine residues remain after the reaction of raw material cyanuric chloride; additional alkaline ethylene glycol extraction and high-temperature distillation purification processes are required to remove organochlorine impurities.
HiSiaddi quickly coordinated the R&D center of Jiangsu Lusheng to set up a special project team for Company A. Targeted optimizations were carried out based on Lusheng’s existing HALS-2020 production process to form five customized solutions:
1. Synthetic process optimization: Adjust the molar ratio of cyanuric chloride and piperidine amine, extend end-capping reaction time from 2h to 4h, and add special acidic neutralizers to stabilize pH at 8.2–8.4.
2. Precise polymerization control: Adopt staged temperature rise (70℃→90℃→110℃), slow dropping over 3 hours and accurate catalyst feeding with error ≤±0.1% to control molecular weight distribution coefficient between 1.25 and 1.3.
3. Advanced purification process: On the basis of post-treatment for general-grade products, add alkaline ethylene glycol extraction (90℃, 2h) and vacuum distillation (120℃, -0.09MPa) to reduce organochlorine residues to 35–45ppm.
4. Customized pellet shaping: Modify pelletizing dies, adopt water-cooled cutting and vibrating screening to obtain uniform 2–3mm cylindrical pellets with dust rate <0.1%.
5. Upgraded batch quality control: Four exclusive tests (pH value, molecular weight distribution, organochlorine residue, volatile matter) are added for each batch, with customized Certificate of Analysis (COA) issued to ensure batch consistency.
HiSiaddi coordinated Lusheng’s R&D department to launch lab trials and synthesize samples per customized solutions. All test indicators fully met targets:
· pH value: 8.3 (Target: 8.0–8.5)
· Molecular weight: 3050, distribution coefficient: 1.28 (Target: <1.3)
· Volatile matter: 0.18% (Target: ≤0.2%)
· Organochlorine residue: 42ppm (Target: ≤50ppm)
· Pellet form: Uniform 2.5mm cylindrical pellets, dust-free.
HiSiaddi simultaneously provided SGS test reports, customized COAs and process specification documents, which were delivered to Company A’s laboratory via express delivery.
Company A conducted blind comparison tests between customized samples and BASF Chimassorb 2020, simulating production and application scenarios of high-end PO films:
1. Process adaptability: No yellowing, no die buildup and stable melt flow rate (±0.2g/10min) during extrusion at 230℃.
2. Weather resistance: Yellowing Index (YI) ≤4.0 after 6000h xenon lamp aging (BASF: 3.8), meeting the requirement of 8-year outdoor weather resistance.
3. Extraction resistance: Additive retention rate reached 93.5% after 100h boiling in 95℃ water (Target: ≥92%; BASF: 94%).
4. Compatibility: No blooming or frost after 72h blending with LLDPE and acidic antioxidant 1010.
Conclusion: The customized samples deliver performance equivalent to imported BASF products, with superior pellet form and low blooming performance that better fit Company A’s production lines, fully satisfying the requirements of high-end agricultural films.
After confirming sample qualification, Company A placed the first customized HALS-2020 order of 3 tons. HiSiaddi tracked the full pilot-scale mass production process:
1. Production scheduling priority: Arrange exclusive customized production lines and dedicated teams to avoid mixing with general-grade products.
