LANDERCOLL Notion of Quality Supremacy

Premium Raw Materials: The Foundation of LANDU's Superior Cellulose Ether Quality

The best-quality raw materials always ensure the consistency and performance of LANDU cellulose ether. Backed by China, a major agricultural country with rich cotton resources, our reliable long-time partners deliver the natural material of every gram that LANDU uses in cellulose ether production. Our refined cotton is uniform and loose white flocculent without impurities such as sawdust, bamboo chips, sediments, oil, and metal. It is composed of carbon, hydrogen, and oxygen at a mass ratio of 44.4%, 6.17%, and 49.39%. Conforming to the advocated green, healthy, and eco-friendly consumption concept, this natural plant cellulose fiber also allows LANDU to push the quality of our sustainable cellulose ether beyond industrial standards.
