At LANDU, quality is the foundation of everything we manufacture. Our comprehensive quality control system spans the entire production chain – from rigorous raw material selection through every production stage to final product testing and analysis.
Every employee shares the commitment to delivering uncompromising quality that meets our customers' most demanding requirements.
Integration with ZOVAE unlocks synergistic potential for production and technologies enhancement.
Advanced factories deliver high-quality cellulose ether, redispersible polymer powder and specialty additives.
By integrating supply chain control, digital traceability, and strict testing, LANDU guarantees high-purity, reliable products.
LANDU ensures strict control over our raw material supply chain, partnering only with certified and audited suppliers, such as Celanese and Sinope.
Advanced batch tracking system monitors raw materials throughout production. Each batch is assigned a unique ID for real-time tracking from receipt to final product.
Strict incoming inspection protocols ensure only compliant raw materials enter our manufacturing process through advanced analytical testing.
15,000m² warehouse with 75,000 tons annual capacity ensures consistent quality and reliable supply chain management.
LANDU factories are equipped with vertical reactors, making the reaction more complete and the quality more stable compared with horizontal reactors.
LANDU adopts an automatic control system in production to reduce manual work, monitoring the whole process to ensure quality stability and consistency.
The mixing equipment that most factories opt for is mechanical mixing, while LANDU uses cyclone mixing. Through air stirring, the mixing is more complete.
LANDU uses super-large mixing equipment to ensure that customers receive products for each bag or pallet with consistent viscosity.
At LANDU, our precisely controlled manufacturing processes ensure that every batch of cellulose ether additives meets strict specifications and global industry standards.
To maximize consistency and minimize human-induced variability, we operate a fully automated production line integrated with advanced process control systems:
Provides real-time monitoring and adjustment of temperature, pH, reaction time, and viscosity, ensuring optimal conditions throughout production.
Automated process control significantly decreases deviation, enhancing product uniformity and reliability.
Continuous parameter tracking allows for immediate corrections, maintaining compliance with specified tolerances.
