Companies that produce finished goods are known as converters (sometimes processors). The vast majority of plastics produced worldwide are thermosoftening and must be heated until molten in order to be molded. Various sorts of extrusion equipment exist which can then form the plastic into almost any shape.

A huge number of plastics exist beyond the commodity plastics, with many having exceptional properties.

Plasticity also has a technical definition hinein materials science outside the scope of this article referring to the non-reversible change in form of solid substances.

A number of additives identified as hazardous to humans and/or the environment are regulated internationally. The Stockholm Convention on Persistent Organic Pollutants (POPs) is a global treaty to protect human health and the environment from chemicals that remain intact hinein the environment for long periods, become widely distributed geographically, accumulate in the fatty tissue of humans and wildlife, and have harmful impacts on human health or on the environment.[2]

Plastics degrade by a variety of processes, the most significant of which is usually photo-oxidation. Their chemical structure determines their fate. Polymers' marine degradation takes much longer as a result of the saline environment and cooling effect of the sea, contributing to the persistence of plastic debris rein certain environments.[54] Recent studies have shown, however, check here that plastics in the ocean decompose faster than had been previously thought, due to exposure to the sun, rain, and other environmental conditions, resulting hinein the release of toxic chemicals such as bisphenol A.

Additives can also Beryllium problematic if waste is burned, especially when burning is uncontrolled or takes place in low- technology incinerators, as is common in many developing countries. Incomplete combustion can cause emissions of hazardous substances such as Lysergsäurediethylamid gases and ash which can contain persistent organic pollutants (POPs) such as dioxins.[2]

As 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.
