Storage:
Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer that has a wide range of applications in industry, including as an ingredient in adhesives, coatings, and film forming agents. Proper storage of PVA is essential to maintain its quality and availability. Here are some general guidelines for PVA storage:
1.Temperature and humidity:
Store PVA in a cool, dry place. Exposure to high temperatures and humidity can lead to changes in the physical properties of the material, such as increased hygroscopicity.
Avoid storing in places with high temperature fluctuations.
2.Sealed container:
Store PVA in an airtight container to prevent moisture absorption. PVA is water-soluble and exposure to water affects its properties.
Use airtight containers or bags to protect materials from environmental conditions.
3.Protection from light:
Store PVA away from direct sunlight and other sources of UV rays. Prolonged exposure to ultraviolet light can lead to polymer degradation.
4.Avoid pollution:
Keep away from contaminants that may affect the performance of polymer products, such as dust, dirt, and chemicals.
Use clean utensils and tools when handling and transferring PVA to prevent contamination.
5.Treatment measures:
During the storage and use of PVA, please follow the correct procedures to avoid the introduction of impurities.
Wear appropriate personal protective equipment, such as gloves and safety glasses, during contact.
6.First in first Out (FIFO):
Follow a FIFO system to ensure that older batches of PVA are used first. This helps to avoid the material being stored for a long time, reducing the risk of degradation.
7.Check for changes:
Check PVA in storage regularly for signs of discoloration, caking, or texture changes. If any anomalies are observed, the cause must be investigated and the suitability of the material assessed.
For the specific grade or type of PVA used, be sure to refer to the specific manufacturer's guidelines and recommendations.
Different formulations may have different storage requirements.
Proper storage methods contribute to the longevity and effectiveness of PVA in various applications.

Overview VAE emulsion is short for ethylene acetate-ethylene copolymerization emulsion, which is a polymer emulsion made of ethylene acetate and ethylene monomer as the basic raw materials and other auxiliary materials through emulsion polymerization. Ethylene and vinyl acetate copolymer is the most important product of ethylene copolymer, generally referred to as EVA. Products with ethylene acetate content in the range of 70%～95% are usually in the emulsion state, called VAE emulsions.
Overview Modified polyvinyl alcohol (PVOH) is graded according to different degrees of polymerization, hydrolysis and copolymerization monomers. The modification of PVA is mainly to use the double bonds, ester groups and the chemical activity of the hydroxyl group after alcoholization of vinyl acetate to change the side chain group or structure, and introduce other monomers to become copolymers dominated by PVA.
Overview Water soluble PVA fiber is a kind of PVA fiber made from polyvinyl alcohol through wet spinning, heat treatment and crimping-oiling in water at normal temperature.
