CAS NO:25067-34-9 Poly(vinyl Alcohol-co-ethylene)

When used for ethanol dehydration, the selectivity of Poly(vinyl alcohol-co-ethylene) pervaporation membrane can reach 1000–10,000, with high separation efficiency. Compared with traditional distillation, the energy consumption is reduced by 30–70%, and no co-boiling agent is required. The process is simpler and the cost is lower.

Poly(vinyl alcohol-co-ethylene) is commonly modified by blending or grafting to enhance its processing properties and moisture resistance. Blending may slightly reduce the barrier properties, while moderate grafting usually can maintain or even improve its core oxygen barrier performance.

1. Exceptional gas barrier properties, effectively addressing the problem of food oxidation and spoilage.
2. No odor, food-grade safety, meeting the core requirements for food contact.
3. Excellent preservation of flavor and resistance to various media, suitable for a wide range of food categories.
4. Outstanding molding and composite properties, meeting the diverse needs of packaging processes.
5. Appropriate temperature resistance, suitable for post-processing of food packaging and usage scenarios.

1.Extremely high chemical and electrochemical stability
2. Excellent thermal stability and resistance to thermal contraction
3. Appropriate microporous structure and ionic conductivity
4. Excellent electrolyte wettability and liquid retention property
5. Balance between mechanical strength and flexibility
6. Low hygroscopicity and oxygen-blocking property

As an interventional treatment liquid embolic agent, the core lies in achieving embolization treatment through liquid injection, in-situ phase transformation for solidification, and precise sealing of the target blood vessels. Its mechanism of action is entirely based on the material's own phase transition characteristics, rheological properties, biocompatibility, physical-mechanical properties, and degradation regulation, and each of these properties is highly compatible with the clinical needs of embolization treatment. This is the key reason why it can become a high-end vascular embolic material. The specific mechanism of action and the corresponding performance correlations are as follows:
