All commercial plastics contain additives. Additives are required to obtain a material that may be used eventually, the amount of options available these additives is impressive, but manufacturers should take them into account in order to make a suitable clark rubber product to the Application required.
The chemical additive is complex and often involves chemical reactions, to ensure its operation, it is necessary to meet the requirements of the final material must meet, for example, a plastic designed to be in the shade does not need resistance against ultraviolet rays, but probably need resistance against the spread of flame, as in the case of a television.
In the chemical industry can find a lot of additives to give them specific properties that suit our needs. Below is a diagram with the most important additives and below is a more detailed explanation of each.
Additives (sorted alphabetically) light absorbers: They are used in plastic products when they want to increase their lifespan. Antibacterial: Prevents bacteria inhabit different material and grow. Antistatic: Avoid the formation and accumulation of static charges.
Antioxidants: To avoid thermal degradation during extrusion (shape dough). Loads: These minerals are added in large proportion to improve some properties of resins such as mechanical strength and toughness and lower the cost. Include: talc, mica, asbestos, fiberglass, cement, graphite, metal powder, etc .; or vegetable, such as wood flour, paper, cotton, etc.
Release agents: These are organic substances that facilitate dessemmotllament of plastic parts. Foaming: They create the final product structure of foam insulation, thus helping to save thermal energy and also save fuel and reduce transportation costs.
Stabilizers: agents are designed to ensure their initial properties and prevent the causes and effects of degradation. Many organic salts of metals and some are highly polluting, so it can not be used for food plastic. Lubricants: used to facilitate the handling machinery during the transformation process. Used in very small amounts, less than 2%.
Pigments: They can be minerals, inorganic or organic dyes or incorporated into the molecular structure or pigments that are placed clark rubber in the spaces left free molecules. Serve to color the plastic. Plasticizers: Plasticizers are added to a polymer to improve their processability and flexibility, they can reduce the viscosity of the polymer clark rubber in the molten state as well as the elastic modulus and glass transition temperature. Flame retardants: used to reduce the flammability clark rubber of a material or to delay the spread of flames along and across the surface of the plastic.
As you can see there are a variety of additives to enhance various characteristics of plastics. This entry WAS posted in General clark rubber on 7 February 2008 by jrosell3. Post navigation Drawing Object Properties
