Celite Usage
High-efficiency filter media (filter aids): Due to their porosity and high permeability, they are widely used in the filtration of beer, beverages, pharmaceuticals, syrups, vegetable oils, and chemical liquids, effectively removing fine suspended solids and bacteria.
Industrial packing materials: Used as functional packing materials in plastics, rubber, paints, and coatings, providing functions such as matting, wear resistance, anti-settling, and enhanced structural strength. Ideal carriers for fertilizers and pesticides, and packing materials for plastics, rubber, and insecticides.
Adsorbent and catalyst carriers: Their extremely large specific surface area makes them ideal carriers for chemical catalysts, chromatographic stationary phases, and powerful adsorbents for waste liquids.
Celite Packaging and Shipping
Packing: 20kg/bag or or jumbo bags (ton bags) according to bulk industrial requirements.
Celite Storage
Store in a dry, clean, and well-ventilated warehouse. Highly hygroscopic and prone to generating dust. Keep containers tightly sealed to prevent moisture absorption. Protect against physical damage, rain, and contamination.
