Self-finishing plastics are materials that require little to no additional surface treatment after they are molded. These plastics typically have a smooth, aesthetically pleasing finish straight from the manufacturing process, which can enhance their appearance and reduce production costs. Examples include certain grades of polycarbonate and acrylic, which maintain clarity and gloss without the need for painting or coating. This property makes them ideal for applications where visual appeal is important, such as in consumer products and automotive components.
Berry Plastics was created in 1967.
Thermosetting plastics
Many parapharmaceutical products are made from plastics.
Hunter Plastics Limited was created in 1967.
- Some plastics made from starch are biodegradable- Another bio-oxodegradable plastics contain a catalyst ( as iron oxide) which improve the degradation in contact with oxygen.Generally biodegradable plastics are as foils not containers.

The high temperature plastics can only be used from the temperature of 135 degree Celsius and lower. Many others thought that high temperature plastics meant that it can handle extremely high temperature but they are wrong.
The means of making the shape Ie injection molding, blow molding, etc
Thermoplastics become less viscous or melt when heated. such plastics may be recycled that means may be moulded into another shape on melting. Thermoset plastics do not - for instance melamine.
It seems there is a typographical error in your question; you likely meant to ask about the difference between thermoplastics and thermosetting plastics. Thermoplastics are materials that become pliable or moldable upon heating and can be remolded multiple times without undergoing any significant chemical change. In contrast, thermosetting plastics harden permanently after being shaped and cannot be remolded upon reheating. This fundamental difference affects their applications, processing, and properties in various industries.

No, not all plastics are petrochemicals. A few examples of bioplastics (plastics made from biologic sources) include Polyhydroxyalkanoates, Polylactic Acids and a wider variety of starch based plastics.
