Molecular sieves are synthetic crystalline aluminosilicates with uniform microporous structures, engineered to selectively adsorb molecules based on size and polarity. Our product line includes 3A, 4A, 5A, 10X, 11X, and XH-7 types, available as off-white/beige spherical beads or cylindrical pellets—ideal for high-efficiency gas and liquid drying across industries.

Key Features & Advantages

• Selective Adsorption: Precise pore sizes (3Å–10Å) target specific molecules (e.g., water, CO₂, hydrocarbons) for tailored purification.
• High Capacity: Exceptional water uptake even at low relative humidity (<10% RH) and elevated temperatures (up to 200°C).
• Thermal Stability: Resists degradation in harsh environments, ensuring long-term performance.
• Regenerable: Reusable via heating (200–350°C) or pressure swing—reduces operational costs.
• Consistent Quality: Strict QC guarantees uniform particle size and pore structure for reliable system integration.

Main Types and Applications

Type Pore Size Key Applications 3A 3Å Drying of ethylene, propylene, and unsaturated hydrocarbons (prevents coking). 4A 4Å General gas/liquid drying (air, natural gas, refrigerants); removes CO₂/H₂S. 5A 5Å Separates normal paraffins from branched/cyclic hydrocarbons; PSA oxygen generation. 10X/11X 8–10 ÅAdsorbs aromatics (benzene, toluene); purifies petrochemical gas streams. XH-7 7Å Dries refrigerants in HVAC/R systems; controls moisture in sealed units.
