5A Activated Molecular Sieve Powder
5A Activated Molecular Sieve Powder is a calcium (Ca) type molecular sieve adsorbent with a pore size of 5 angstroms with A type crystal structure. It has excellent dispersion, adsorption activity and chemical stability, preferably for the occasion of selective adsorption of small molecules and polar molecules.
Compared with 3A and 4A types, 5A type has a higher water absorption capacity and can also absorb carbon dioxide gas generated during the polyurethane production process, which can improve the curing effect and storage stability of glue, coating and paint.

Application Of Activated Molecular Sieve Powder 5A
- It can remove residual moisture from polyurethane raw materials and semi-finished products (including polyols, isocyanates, prepolymers, and pigments, etc.).
- It is used in two-component polyurethane systems to eliminate foaming, reduce gloss loss, improve strength, and improve adhesion.
- It is used in one-component wet curing systems formulated with aliphatic polyisocyanates, which can overcome the shortcomings of traditional one-component wet curing, making the product non-foaming, fast curing, and good storage stability.
- Electronic Potting Glue
- Honeycomb Panel Adhesive
- Rubber Athletic Flooring
- Repair Paint

Activated Molecular Sieve Powder Case Study
Xintao has many export and customer service cases, you can learn about them here.
Activated Molecular Sieve Powder: New Choice For Two-Component Polyurethane
During the production of two-component polyurethane, bubbles are often generated due to the influence of moisture, which affects the product quality. The activated molecular sieve powder produced by Xintao has become a new choice
Activated Molecular Sieve Powder Solves Polyurethane Bubble Problem
During the glue production and pouring process, the problem of colloid bubbles is often encountered. The bubbles in the colloid will affect the bonding effect between the glues, resulting in a shortened service life and even colloid separation. How do you solve this problem?
Electronic Potting Glue Application Case
The performance of potting compound will be affected by moisture, including the moisture content of the potting compound itself and its ability to isolate moisture after sealing. Adding activated powder molecular sieve can effectively solve the problem.

FAQ
It can be used for any product where trace moisture in the glue will affect the properties of the product. If you use traditional dehydration equipment, the entire dehydration process takes a long time. You can also choose activated molecular sieve powder to speed up the dehydration process.
The difference is that molecular sieve powder is the single raw material for producing molecular sieves, which has low activity and cannot absorb water. Activated molecular sieve powder is a powder with adsorption activity produced by adding specific additives and dehydrating at high temperature.
Usually, the addition ratio is 2-6%. The amount of activated molecular sieve powder to be added is determined according to the trace amount of water that needs to be removed in the system. The static water adsorption is ≥24%, which means that under certain conditions, the amount of water that the activated powder can absorb is 24% of its own weight.
No. Activated powder is also a kind of molecular sieve, which belongs to static molecular sieve and cannot be regenerated in the system. The adsorption and desorption of molecular sieves are conditional. Desorption requires high temperature and low pressure. When used by customers, the molecular sieve activated powder forms a uniform substance with polyurethane and does not have the desorption conditions. This is also the reason why the activated powder cannot be regenerated.
