What types of hot melt adhesives are there? The types and compositions of hot melt adhesives, commonly used hot melt adhesives are mainly PA/PES/TPU/EVA/LDPE/HDPE.
First, PA hot melt adhesive
PA hot melt adhesive is divided into high temperature and low temperature. Imported rubber is widely used in clothing and shoe materials, and has excellent dry cleaning resistance.
Second, PES hot melt adhesive
PES hot melt adhesive is widely used in the field of clothing. Its super water-resistant type is welcomed by customers, and its adhesion is very stable when it is combined with polyester fabric.
Third, EVA hot melt adhesive
EVA hot melt adhesive has poor washing resistance and belongs to imported rubber. It is widely used in automotive interiors and other fields. It is characterized by low temperature bonding and saves operating costs.
Fourth, LDPE hot melt adhesive
LDPE hot melt adhesive is similar to EVA in washing property. It is mainly used in automotive interiors. It can be bonded at low temperature. Its powder is coarse powder, it is not easy to use powder point process. More applications.
Five, HDPE hot melt adhesive
HDPE hot melt adhesive is a high temperature hot melt adhesive, imported rubber, which has superior high temperature resistance and high temperature water absorption performance. It is widely used in collar lining glue and has strong adhesive force, but its melting point is high and needs high. The operating temperature makes it less useful in other fields.
Sixth, TPU hot melt adhesive
TPU hot melt adhesive and PU/TPU material have strong adhesion, and are widely used in the field of shoe materials. There are many types of TPU hot melt adhesives. The melting points, dissolved fingers and adhesion of various TPUs are different. The following two main commonly used TPUs are introduced, which are divided into imported TPU and domestic TPU. They have good performance in washing and high temperature resistance, and the adhesion is stable. The difference lies in the stability, the purity of imported TPU is high, after many experiments. The values are stable and the performance is stable, but its high cost makes it only a hot melt adhesive for high-end materials.
