Products and Services

BRACE GmbH offers a variety of services in the area of Microgranulation and Microencapsulation. The different areas can be described as follows:

Products

Microspheres: Spherical homgeneous granules, i.e. of one material or a homgeneous mixture
Microcapsules: Spherical granules with a solid shell and a liquid or solid core.

Services

Contract Manufacturing: Development or optimization of an own or a customer's recipe and manufacturing of spherical granules thereof (Microspheres or Microcapsules)

Microencapsulation: Recipe development or optimization with the aim to encapsulate an active component with a shell material and produce spherical granules thereof

Process

The patented BRACE microsphere technology is of great help if one wants to produce spheric granules from varying materials. The BRACE technology is applicable to nearly any material that can be liquefied and solidified again afterwards.

The liquefaction of the starting material can be achieved by different means: the dissolving of the raw material in nearly any solvent choosen (this process is called a binder process because a temporary binder is often used), the melting of the raw material in a melting furnace (melting process), or the generation of a gel from a sol (SOL-GEL process). For the production of microcapsules, a combination of these processes is often used.

Microcapsules

The BRACE double-nozzle processes produce real microcapsules with a solid shell and a liquid or solid core in a single step.

The material for the inner core can be chosen independently from the shell material unless it weakens the stability of the shell. The shell material, on the other hand, can be chosen to be a solution, a molten mass or a sol or a combination of these just like with the Microspheres. The hardening of the spheres is done as described for microspheres. The result is a capsule with a solid shell and a solid (if a molten mass is used for the inner core) or a liquid core.

Microencapsulation

BRACE GmbH offers besides the product development contract manufacturing. Small and medium quantities (up to approx. 50 t per product and year) can be produced, packed and shipped by BRACE, larger quantities are possible, too. Dedicated Microsphere Units for certain customer products are possible and will be offered by request. The possible quantities depend on the diameter of the spheres and of the material. To produce even smaller quantities for competitive prices, a contract can be offered to calculate multiple batches as a single batch.

Contract Manufacturing

BRACE GmbH offers besides the product development contract manufacturing. Small and medium quantities (up to approx. 1000 t per product and year) can be produced, packed and shipped by BRACE, larger quantities are possible, too. Dedicated Microsphere Units for certain customer products are possible and will be offered by request. The possible quantities depend on the diameter of the spheres and of the material. To produce even smaller quantities for competitive prices, a contract can be offered to calculate multiple batches as a single batch.
