Which car desiccant is better to choose? The high-quality desiccant used in the car needs to have the following characteristics:

1. High water absorption: can absorb ultrapure water hundreds or even thousands of times its own weight.

2. High water absorption rate: each gram of super absorbent resin can absorb hundreds of grams of ultrapure water within 30 seconds.

3. High water retention: Under external pressure, the water in the gel after water absorption is more difficult to squeeze out.

4. High swelling: The volume of the super absorbent resin gel after absorbing water expands hundreds of times.

5. Ammonia absorption: The low-crosslinking acrylic homopolymer type super absorbent resin contains carboxyl anion in its molecular structure, which can be absorbed by ammonia, and has a significant deodorizing function.
