What’s the different of PU glue strip and Silicone strip?

As we know there are many IP rating for LED strip light,most waterproof strip were made of PU glue or silicone.Both PU glue strips and silicone strips are adhesive strips that are utilized in a variety of applications. They differ in composition, characteristics, and recommended usage, though.

Composition:

PU (Polyurethane) Glue Strip: This adhesive is constructed of polyurethane. This glue is made by combining a polyol and an isocyanate, yielding a strong and versatile adhesive.
Silicone Strip: This is a silicone-based adhesive strip. Silicone is a synthetic material created from silicone polymers that has high heat resistance and flexibility.

Properties:

PU Glue Strip: PU adhesive strips are well-known for their outstanding bonding strength, resistance to moisture and chemicals, and flexibility. They adhere well to a wide range of materials, including wood, metal, plastic, and fabric.

Silicone adhesive strips are extremely heat resistant, waterproof, and have good electrical insulating qualities. They are frequently employed in applications that demand powerful sealants, such as door, window, and joint sealing.

Recommended Usage:

PU Glue Strip: PU adhesive strips are extensively used in construction, automotive, and industrial sectors for bonding and sealing. They are suitable for connecting various materials together, resulting in a strong and long-lasting bond.
Silicone adhesive strips are frequently used for sealing and insulating applications. They are appropriate for applications requiring resistance to high temperatures, chemical exposure, and water penetration. HVAC systems, electrical panels, and automobile sealing applications all make extensive use of silicone strips.

To summarize, the primary distinction between PU glue strip and silicone strip is found in their composition and properties. Silicone strip provides good heat resistance, waterproofing, and electrical insulation, whilst PU glue strip provides strong bonding and flexibility. The decision between the two is determined by the individual application and the desired qualities.
