Most of HMPSA for auto are used in automobiles, but different types will be selected for different parts and applications.
According to its function, it can be divided into bonding type and sealing type. Sealing type mainly uses butyl glue, which is not discussed here.
According to the use and construction temperature, it can be divided into ordinary type and heat-resistant type. Cars are mainly driven outdoors, and hot-melt adhesive is generally required to have certain heat-resistant performance.
Characteristic
The traditional method of headlamp is to use the rubber sealing strip with holes to compress and seal through screws.
After changing to hot-melt pressure-sensitive adhesive, it can be bonded quickly and play the role of sealing, which not only reduces the cost, but also is conducive to automatic production.
Hot melt adhesive has good temperature resistance, high bonding strength and vibration resistance.
In the past, the dashboard, ventilation duct and interior trim fixing buckle of the bridge were fixed and connected mechanically, which was not only time-consuming and laborious, but also inefficient and poor sealing performance.
After using hot-melt pressure-sensitive adhesive, the production efficiency and product quality are greatly improved. Temperature resistant hot melt adhesive is mainly used.
Application
HMPSA for auto has the characteristics of rapid curing.
As an environmental friendly hot melt adhesive, it is widely used in automobile roof, automobile door panel, automobile carpet, automobile harness and tire protection.
At the same time, it can also be used for the bonding of automobile labels, automobile filter elements, lamps, bridge instrument panels and other automobile manufacturing parts.
