Product Overview and Features

Molecular Sieve is a synthetic crystalline aluminosilicate (Zeolite) characterized by uniform molecular-sized pores. It acts as a molecular filter, selectively adsorbing molecules based on their size and polarity.

• Automotive AC Protection: Exhibits exceptional moisture adsorption even at low humidity levels. It prevents compressor corrosion and expansion valve clogging caused by icing. Fully compatible with common automotive refrigerants and lubricants (e.g., POE, PAG).
• Industrial Efficiency: Widely used for dehydration, gas separation, and purification. It is highly effective for CO₂ removal in air separation plants and industrial deodorization processes.
• High Durability: Features a robust and stable crystal structure resistant to pressure and temperature fluctuations. Low dust generation ensures the safety of sensitive components, while uniform particle size allows for optimal airflow and extended service life.

Properties and Applications

We offer standard grades including 3A, 4A, 5A, 13X, and the automotive-specific XH series, available in various forms:

• Pellet: 3.2 mm, 1.6 mm
• Beads: 4x8, 8x12
• Powder: 10μm or smaller

General Applications:

• Dehydration: Industrial gases, air separation units (ASU), and Li-ion battery manufacturing for EVs.
• Separation and Purification: CO₂ removal in ASUs, hydrogen stations for fuel cell vehicles (FCV), and raw materials for semiconductor manufacturing.
• Deodorization: Food packaging (resin odor removal) and body powders.
• Humidity Control: Heat pumps and industrial dehumidifiers.
• Special Purposes: Activated sludge treatment and as a water softener in synthetic detergents.
