13X Molecular sieve activated powder

Molecular sieve activated powder
13X molecular sieve activated powder is a dehydrated synthetic zeolite powder with an effective pore opening of about 10 angstroms. It can adsorb water, CO₂, H₂S, and larger molecules such as aromatics and branched hydrocarbons, providing high adsorption capacity. This makes it suitable for air separation, natural gas purification, CO₂ removal, and general gas drying applications. The powder offers excellent dispersibility, chemical inertness, and strong moisture-adsorbing performance.

Product Description

High-Capacity Wide-Pore Scavenging Powder

13X Molecular Sieve Activated Powder (Type X Sodium-X Form)

Engineered by processing synthetic sodium X-type zeolite crystals into an ultra-fine, highly reactive powder featuring a wide 10-angstrom pore opening. It acts as an elite active chemical drying agent designed to scavenge deep moisture, capture larger molecules, and eliminate gas or bubble generation in demanding industrial formulations.

Wide Pore Architecture & Deep Molecular Capture

13X molecular sieve activated powder features a sodium-X crystal structure with an expanded 10-angstrom pore opening. Supplied as an unshaped micronized powder, it disperses evenly throughout liquid polymer systems, resins, and specialized coatings to intercept water and larger polar impurities instantly.

Because of its larger pore size, it adsorbs not only moisture but also molecules with critical diameters up to 10 angstroms, such as heavier hydrocarbons, carbon dioxide, and sulfur compounds. This makes it a premier active filler for systems requiring deep purification and absolute structural integrity.
