Does Neoprene absorb water? Does Neoprene repel water? Neoprene does not absorb water; it repels water. The amount of air inside neoprene will determine how much water can penetrate it. The more air Neoprene contains, the less water can soak into the material. Also, the added nitrogen in Neoprene increases the insulation and increases the overall buoyancy because the cells of the fabric do not absorb water.
What Is Neoprene?
DuPont Company produced Neoprene as the first synthetic rubber in 1930. The technical name of Neoprene is polychloroprene.  It is a rubber product with many unique properties.
Manufacturers made it from the combination of oil and petroleum and dubbed it chlorine. Producers originally used Neoprene in television and other gadgets.
Neoprene has many good properties, such as being resistant to cold and hot temperatures and other environmental factors. Likewise, it can prevent water from penetrating its surface. 
General Neoprene Uses

Neoprene-made materials can keep your body heat inside and prevents cold temperatures from getting in. Therefore, it is also a good material for gloves and boots.
Neoprene can keep off liquid getting into diving gear and electronic devices to protect them from getting damaged. This property is due to Neoprene’s water or liquid immiscibility.
Seat covers with Neoprene material are also popular, especially with families who have kids. You can allow your kids to have fun while ensuring that your car or sofa seats remain dry.
Does Neoprene absorb water? Does Neoprene repel water? Neoprene repels water. It does not absorb water. This means it is waterproof. It is resistant to oil and heat as well. Neoprene clothing and wetsuits are stitched and glued in a way that gives them extra resistance to water.
5. Slow Rate of Oxidation
Neoprene has a slow rate of oxidation, making it perfect to use outdoors for long periods. So, it is also effective when used in personal paraphernalia and traveling items.
6. Less Prone to Corrosion
Neoprene does not corrode easily like other rubber materials. You can choose it safely over other rubber types. But take note that it can also corrode over time due to wear and tear.
You can wash Neoprene-containing materials with mild detergent and water. Do not apply the detergent directly to the item. Wash the item first with water, then prepare a mild detergent-water solution. Dissolve the detergent in an ample amount of water and use this to wash off your item gently.
If you are washing the cover of your phone or similar gadgets, ensure that you do not introduce water to your phone or gadget. The cover may be waterproof, but most phones and gadgets are not.
