The difference between hot melt tape and acrylic tape

1. Adhesive components

Hot melt adhesive tape: The adhesive of hot melt adhesive tape is a type of glue based on hot melt adhesive. It becomes liquid when heated and is applied to the tape substrate. After cooling, it solidifies and forms a strong bond. Hot melt adhesive is a solvent-free polymer, typically a mixture of resin and wax.

Acrylic tape: The adhesive of acrylic tape is based on acrylic resin. Acrylic glue can exhibit good adhesion at room temperature and has strong UV resistance, weather resistance, and chemical resistance.

2. Curing method

Hot melt tape: The curing of hot melt tape is physical curing, which solidifies the adhesive through cooling and hardening processes, so it usually requires heating to apply and bond. The tape will quickly reach its maximum viscosity after cooling.

Acrylic tape: The curing of acrylic tape is chemical curing, and acrylic adhesive has strong self adhesiveness, which can quickly bond at room temperature without the need for external

3. Applicable temperature and temperature resistance

Hot melt tape: Hot melt tape usually has good high temperature resistance, but its performance may decrease in extremely low temperature environments, especially at low temperatures where it may become brittle or lose its stickiness.

Acrylic tape: Acrylic tape has good resistance to high and low temperatures and is suitable for use in a wide temperature range. It has stronger adaptability to temperature changes and is not easily affected by heat and cold.

4. Weather resistance and UV resistance

Hot melt tape: When exposed to sunlight and harsh environments for a long time, the performance of hot melt tape may be affected. Although hot melt adhesive tape has good short-term adhesion, it may experience aging or a decrease in viscosity under strong ultraviolet radiation.

Acrylic tape: Acrylic tape is superior to hot melt tape in terms of UV resistance and weather resistance. It can withstand prolonged exposure to sunlight, humidity, and high temperatures, making it suitable for outdoor or long-term applications exposed to sunlight.

5. Adhesive force and initial viscosity

Hot melt tape: The initial adhesion of hot melt tape is very strong, which can quickly adhere and provide strong fixing force, suitable for quick packaging and packaging operations. Its adhesion is also relatively high, especially in the short term.

Acrylic tape: Acrylic tape has low initial adhesion, but it has strong durability. Over time, acrylic tape will provide more stable and long-lasting adhesion, suitable for long-term packaging and fixing needs.

6. Applicable scenarios

Hot melt tape: Hot melt tape is suitable for applications that require fast bonding and high production efficiency, such as automated packaging lines, quick sealing, temporary fixation, etc. It performs well in fast packaging and efficient production environments, especially in the logistics industry where it is widely used.

Acrylic tape: Acrylic tape is suitable for occasions that require high weather resistance, temperature resistance, and UV resistance. For example, suitable for outdoor use, electrical equipment, long-term fixed packaging, etc.
