We all know about the development of sedans in recent years. Sedans have now become an essential transportation item in our daily lives, providing bento for our daily lives. The use of hot melt adhesive retinas in car interiors is also common. All kinds of car interior composites are inseparable from hot melt adhesive retinas. In this article, we will review the application of hot melt adhesive retinas in car seat cushion composites.
The material types of car seat cushions are basically leather and sponge composites, which are probably mainly textile non-woven fabrics and sponge composites. Therefore, in order to find out what type of hot melt adhesive retina is used for car seat cushion composites, in fact, the first step is to select the hot melt adhesive retina according to the type of composite material. The primary requirements for hot melt adhesive retinal composites for car seat cushions can be summarized in the following aspects: the first is the requirement for adhesion; the second is the request for breathability after lamination; the third is the requirement for environmental protection.
We are based on the type of composite material for car seat cushions and the request for hot melt adhesive film composites. Hot-melt adhesives used in car seat cushions are mainly hot melt adhesive retinal types. There are two types of raw materials we can think about: one is PA type hot melt adhesive retina, and the other is TPU type hot melt adhesive retina. The hot melt adhesive retina of these two raw materials has a good effect on the compatibility of leather and sponge, whether it is a non-woven fabric or sponge composite. Good compatibility means there is no problem with the adhesive strength. Satisfied with the requirements in terms of bonding strength, let's take another look at the requirements for breathability and environmental protection. Hot melt adhesive retinas have better breathability than adhesive films. As for its environmental protection function, not to mention, one of the major characteristics of hot melt adhesive retina is that it is environmentally friendly!
The application of hot melt adhesive retina in car seat cushion composites can be said to have addressed the problem of adhesives becoming a source of pollution for car interiors at the source.
