Flame retardant hot melt adhesive film is a type of hot melt adhesive film with flame retardant function. As a polymer material, hot-melt adhesive film is inherently flammable. However, in many situations, we need to make adhesive products have a higher fire retardant grade, increase the safety of their use, and avoid safety accidents during use.
1. How is flame retardant hot melt adhesive film produced?
When flame retardant hot melt adhesive films are produced, flame retardants are added to the raw material formula, and the flame retardant and raw material particles are mixed and granulated. The finished particles are then fed into a film production machine, coated or cast to produce a flame retardant hot melt adhesive film. Flame retardant hot melt adhesive film usually belongs to the PES hot melt adhesive film system.
2. Flame retardant mechanism of flame retardant hot melt adhesive film?
The flame retardant mechanism of flame retardant hot melt adhesive film depends specifically on what kind of flame retardant is used. Judging from the flame retardant mechanism of flame retardants, they mainly have four effects in the flame retardant process, namely heat absorption, coverage, reaction suppression, and asphyxiation. For example, Al (OH) 3 flame retardants improve the flame retardant performance by increasing the heat capacity of the polymer so that it absorbs more heat before reaching the thermal decomposition temperature. This type of flame retardant exerts its characteristic of absorbing a large amount of heat when combined with water vapor, improving its own flame retardant ability.
3. In what fields is flame retardant hot melt adhesive film used?
Flame retardant hot melt adhesive films generally have a certain range of applications in the field of electronics and decorative building materials. These fields often involve fire prevention requirements, so there will be requirements for fire retardant materials.
