Introduction
When Europe’s biggest fully-integrated polyester continuous filament yarn producer needed reliable adsorbents for their critical manufacturing processes, they turned to XINTAO. After a successful trial with our 13X molecular sieve (500kg), 4A molecular sieve (1,000kg), and activated alumina (300kg) in November 2023, they placed a repeat order for 1,500kg of 4A molecular sieve in June 2024—a clear testament to our product quality and service excellence.
Why Leading Manufacturers Choose Our Adsorbents
1.Unmatched Product Performance
4A Molecular Sieve: Ideal for deep drying solvents and removing trace water in polyester production, ensuring fiber strength and consistency.
13X Molecular Sieve: Effectively captures CO₂ and hydrocarbons, protecting catalysts in polymerization.
Activated Alumina: Controls acidic contaminants, extending equipment lifespan.
2. Rigorous Quality Assurance
ISO 9001-certified production with batch-to-batch consistency.
Customizable particle size to match reactor specifications.
3. Reliable Supply
Secure packaging (moisture-proof paper bags/jumbo bags/paper drums/steel drums) to preserve adsorbent activity.
Case Study: How Our Adsorbents Optimized Their Process
| Challenge | Our Solution | Result |
| Moisture affecting yarn quality | 4A molecular sieve (<0.1% H₂O uptake) | 30% fewer defects, higher tensile strength |
| Catalyst poisoning by CO₂ | 13X molecular sieve (CO₂ capacity: 18wt%) | 20% longer catalyst life |
| Acidic byproduct buildup | Activated alumina (pH stability 6–8) | Reduced reactor corrosion |
