B1 Compound

B1 Compound

B1 Compound is a special core formulation used in the production of B1/B2 class aluminium composite panels, providing balanced fire performance and production stability. B1 compound, which plays a critical role in terms of mechanical strength, homogeneous distribution and process compatibility in the panel structure, has been developed to provide reliable performance in facade and architectural applications.

What is B1 Compound?

B1 Compound is a mineral based filler compound developed for manufacturers aiming flammable (class B1) performance in aluminium composite panel production. It has been optimised to provide stable flow and homogeneous distribution in the production line while increasing fire resistance with its high filling ratio.
 
The formulation offers stable viscosity during the extrusion process and maintains process stability despite the high filler content. This minimises problems of voids, segregation or heterogeneous density on the panel surface. An optimum balance between mechanical strength, panel rigidity and dimensional stability is achieved.
 
B1 Compound is designed to operate on standard ACP lines without the need for additional modification. It offers stable quality and predictable performance in mass production.
 
Technical Advantages:
-DIN 4102 Class B1 performance target
-High mineral filler ratio
-Stable melt flow properties
-Stable extrusion performance
-Homogeneous density distribution
-Formulation suitable for continuous production

Where is B1 Compound Used?

Composite panels using B1 compound are widely preferred in the following areas:

Commercial building facade systems
Industrial plant coatings
Advertising and signage applications
Advertising and signage applications
Interior architectural surface coatings

B1 Compound's Panel Performance Role

The performance of an aluminium composite panel is determined not only by the surface quality but also by the homogeneity of the core structure. B1 compound:

Supports bond strength between layers
Contributes to the impact and bending resistance of the panel
Stable extrusion process in the production line
Helps measure consistency

Therefore, B1 compound quality is the key determinant of the final panel performance.

B1 Compaund Production Process and Quality Discipline

Recipe stability, homogenous mixing and process control are critical in B1 compound production. The density balance and distribution homogeneity of the core material minimises surface deformation and internal stress in the panel production line.

A quality B1 compound:

  • Ensures stable flow during extrusion

  • Helps prevent layer segregation

  • Supports panel stability after shipment

  • Maintains long-term surface smoothness

Advantages of B1 Compound

  • Structure suitable for B1/B2 class panel production

  • Process efficiency in the production line

  • Stable fire performance

  • Mechanical stability support

  • Wide project compatibility

Conclusion

B1 Compound, Class B1/B2 is the basic building block of aluminium composite panel systems. When used with the right formulation and disciplined production process; it offers a reliable, stable and performance-oriented solution for both the manufacturer and the applicator.

The compound solutions developed under the A2 Core brand are safely preferred both in the domestic market and in export projects with its Turkey-based production power.
