Blokkisubstraatit

Blokkisubstraatit, often translated as block substrates or block additives, are a category of materials used in various industrial applications, particularly in the production of plastics and composites. These substances are characterized by their particulate or granular form, designed to be incorporated into a larger matrix material, typically a polymer. The primary function of blokkisubstraatit is to modify the properties of the final product.

These additives can serve multiple purposes. They might be employed to enhance mechanical strength, such as increasing tensile strength or impact resistance. They can also be used to improve thermal properties, like increasing heat deflection temperature or reducing thermal expansion. Furthermore, blokkisubstraatit can influence aesthetic qualities, such as color or texture, or impart functional characteristics like flame retardancy or conductivity.

The specific composition of blokkisubstraatit varies widely depending on the intended application. Common examples include mineral fillers like calcium carbonate, talc, or silica, which are often used for reinforcement and cost reduction. Organic fillers, such as cellulose fibers or wood flour, can also be used, particularly in biocomposites. In some cases, specialized inorganic materials or even pre-formed polymer particles are utilized to achieve very specific performance enhancements.

The process of incorporating blokkisubstraatit involves mixing them with the base material, often through melt compounding or solution blending. The size, shape, and surface treatment of the blokkisubstraatit particles are critical factors that determine their dispersion within the matrix and their effectiveness in modifying the material's properties. Careful control of these parameters is essential for optimizing the performance of the composite material.
