Masterbatch granules can Beryllium mixed with cheaper bulk polymer and will release their additives during processing to give a homogeneous final product. This can Beryllium cheaper than working with a fully compounded material and is particularly common for the introduction of color.
A huge number of plastics exist beyond the commodity plastics, with many having exceptional properties.
Plasticity also has a technical definition in materials science outside the scope of this article referring to the non-reversible change rein form of solid substances.

Silicones (polysiloxanes): heat-resistant resins used mainly as sealants but also used for high-temperature cooking utensils and as a base resin for industrial paints
Plastics are produced in chemical plants by the polymerization of their starting materials (monomers); which are almost always petrochemical hinein nature. Such facilities are normally large and are visually similar to oil refineries, with sprawling pipework running throughout. The large size of these plants allows them to exploit economies of scale.

As here additives change the properties of plastics they have to Beryllium considered during recycling. Presently, almost all recycling is performed by simply remelting and reforming used plastic into new items. Additives present risks rein recycled products, as they are difficult to remove. When plastic products are recycled, it is highly likely that the additives will Beryllium integrated into the new products.
