Let’s talk about how to choose “hot melt adhesive“. Hot melt adhesive is classified by material composition:
EVA hot melt adhesive: EVA (ethylene-vinyl acetate copolymer) hot melt adhesive is a common type of hot melt adhesive, which has good bonding performance and flexibility, and is relatively cheap. It is also used in the manufacture of car lights. However, its high temperature resistance is relatively weak, and it may not be suitable for some car lights in high temperature environments.
Rubber-type hot melt adhesive: Rubber-type hot melt adhesive has high viscosity and elasticity, strong adhesion to various materials, and can adapt to the vibration and impact of car lights during driving. At the same time, rubber-type hot melt adhesive also has good weather resistance and chemical corrosion resistance, suitable for long-term use of car lights.
APAO hot melt adhesive: APAO (amorphous α-olefin copolymer) hot melt adhesive is a high-performance hot melt adhesive with excellent high temperature resistance, aging resistance and bonding performance. In the manufacture of automotive lamps, APAO hot melt adhesive is often used in some parts with high temperature and performance requirements, such as the sealing and bonding of headlights.
