What Is Difference Between PVC Foam Tape And EVA Foam Tape?

PVC foam tape and EVA foam tape are both popular choices for adhesive tapes used in a variety of industries. While there are similarities in their appearance and function, there are also notable differences between the two.

Firstly, PVC foam tape is made from polyvinyl chloride, while EVA foam tape is made from ethylene vinyl acetate. This difference in material can affect the properties of the tape. PVC foam tape is known for its superior resistance to chemicals, UV light, and weathering. It can also withstand higher temperatures compared to EVA foam tape. EVA foam tape, on the other hand, is softer and more flexible, making it easier to apply on curved or irregular surfaces.

Another difference is in their adhesive properties. PVC foam tape usually has a stronger adhesive due to its denser and harder foam structure. This makes it ideal for applications requiring a strong hold, such as sealing doors and windows, or mounting heavy objects. EVA foam tape, on the other hand, has a lower tack adhesive, making it easier to reposition or remove without leaving residue.

In terms of cost, EVA foam tape is generally more affordable compared to PVC foam tape due to its simpler manufacturing process and lower material cost. However, the choice between the two ultimately depends on the specific requirements and intended use of the tape.

Overall, both PVC foam tape and EVA foam tape have their own strengths and weaknesses. When choosing between the two, it's important to consider factors such as temperature resistance, adhesive strength, flexibility, and cost to ensure that the right tape is selected for the job.
