Differences between hot melt adhesive film TPU and PES

Both TPU hot melt adhesive film and PES hot melt adhesive film are conventional material types of hot melt adhesive adhesives in hot melt adhesive product systems. Their role is to solve the problem of bonding and composite of materials, which are basically the same in terms of production molding process and use method. But what is the difference between them, and what do you need to pay attention to in choosing to use?

1. Different materials:

The difference between the two is first in terms of raw materials. The main component of TPU hot-melt adhesive film is polyurethane, which is an elastomer material. The color can also be divided into high transparency, transparency and white fog surface due to different melting points. The main component of PES hot-melt adhesive film is copolyester, which is a white translucent material.

2. Differences in softness and comfort:

There is a big difference between the two in terms of softness and comfort. TPU hot melt adhesive film has very good elasticity and performs well in terms of softness and comfort. However, the main raw material of PES hot-melt adhesive film is a kind of inelastic polymer material, so its softness and comfort are relatively poor, far inferior to TPU hot-melt adhesive film. Therefore, TPU hot-melt adhesive film is also more widely used than PES hot-melt adhesive film.

3. Differences between water and dry cleaning resistance:

TPU hot-melt adhesive film and PES hot-melt adhesive film have good water washing resistance, and PES hot-melt adhesive film has better water washing resistance than TPU hot-melt adhesive film. However, the washing resistance of TPU hot-melt adhesive film can meet the requirements of most industries. However, in terms of dry cleaning resistance, TPU hot-melt adhesive film is poor, and PES hot-melt adhesive film is also good in dry cleaning resistance.

4. Differences in temperature resistance:

The high temperature resistance of TPU hot melt adhesive film is 110 ℃, and the low temperature resistance is - 20 ℃; The high temperature resistance of PES hot-melt adhesive film is above 120 ℃, and the low temperature resistance is minus 30 ℃.

5. Differences in melting point:

TPU hot-melt adhesive film has more melting point types than PES hot-melt adhesive film. The melting point span is relatively large, and there are basically high and low temperatures. The low melting point can reach 65 degrees, and the high melting point can reach 180 degrees. The melting point of PES hot-melt adhesive film is about 110 degrees, and the span is relatively small!
