VHB acrylic double-sided adhesive is the abbreviation of English Very High Bond. Chinese translation is very high-strength bonding. When dealing with some difficult materials, it is very strong when used with primer.
Acrylic double-sided tape is indeed more expensive than foam double-sided tape.
1. The substrate is different. Acrylic is made of pure acrylic glue. There is no substrate.
2. There is a substrate for double sied PE/EVA foam tape, and foam is a substrate. Adding acrylic glue to the foundation of the foam, the viscosity is not the same. This is the difference. Their cost is not the same.
