2. 5 Common Waterproof Materials to Outdoor Light Strips

What could be used to waterproof led strip lights for pools? It has to be a super clear chemical so the light can shine through.

And there are five that meet the requirements: Silicone, PVC, PU(Polyurethane), PO(Polyolefin), Epoxy resin.

Silicon

Silicon is a popular material for waterproof LED strips due to its high resistance to water and other liquids. It is flexible and can easily conform to various shapes and sizes, making it ideal for use in a wide range of applications.

PVC

PVC (Polyvinyl Chloride) is another popular material used for waterproof LED strip lights. It is also flexible and easy to shape, making it ideal for use in curved or uneven surfaces. PVC is also resistant to water and other liquids, making it a popular choice for outdoor use.

PU

PU (Polyurethane) including PU glue and TPU(Thermoplastic Polyurethane), can be used as a waterproof shell for LED light strips. PU glue provides strong bonding and weather resistance, and TPU offers flexibility and abrasion resistance. Both can effectively seal the LED strip from moisture and others.

PO

PO (Polyolefin) usually be used as clear heat shrink tubing, and let heat shrink sleeve flexible and flame retardant. When heat is applied, the tubing shrinks and conforms tightly around the LED strip, creating a protective barrier that seals out moisture and other contaminants.

Epoxy Resin

Epoxy Resin is a popular material used to encapsulate LED strips for waterproofing. It is made by two parts(resin and hardener) and mixed together and then applied to the LED strip. Once cured, epoxy provides excellent water resistance and durability.
