Synthetic polymers are the main components for the production of plastics used in all sectors of human life. Our optical brighteners can be readily used in most of these polymers. The most important ones include:
Thermoplastic polyethylene is the most widely used plastic in the world, which is primarily used for packaging such as films, bottles or containers, as well as pipes and cable insulation. Based on its density, polyethylene is divided into four types: HDPE, MDPE, LDPE, LLDPE.
Polypropylene is the second most important plastic and accounts for one fifth of the total plastics production. It is harder and thermally more resistant than polyethylene. Polypropylene is found in synthetic fibres and in various packaging segments.
Natural polyamides are peptides and proteins (hair, wool, silk, protein). Synthetic polyamide is also known as nylon – after the first pure synthetic fibre that DuPont brought onto the market in 1939. Polyamides are the oldest useful synthetic fibres and still today rank among the most important ones.
Ethylene vinyl acetate (EVA)
Ethylene-vinyl acetate refers to a group of copolymers which is used predominantly as hot-melt adhesive or for special applications. Ethylene vinyl acetate is also used in photovoltaics. This involves attaching solar cells by means of EVA to build up a solid composite.
Polyvinyl chloride (PVC)
PVC ranks among the oldest and most common commercial plastics, which is used in large quantities in a wide range of applications. Obtained through radical polymerisation of vinyl chloride, PVC is a hard and brittle plastics with no additives.
Thermoplastic polystyrene (PS) has developed into a widely used “bulk plastics”. Polystyrene is used for components of electrical appliances or for food packaging. Expanded polystyrene is used as foamed plastics for thermal insulation of buildings, such as packaging material or in model building.
Polyurethane (PU / PUR)
Polyurethane is one of the most versatile plastics primarily used in upholstered furniture, sponges, mattresses, packaging materials or building blocks (insulation). Polyurethane is also found in rolls and rollers. Other important areas of application include the adhesives sector, as well as the varnishing and coating world.
Acrylnitril-Butadien-Styrol wird in erster Linie von der Automobilindustrie und der Elektroindustrie verwendet. Darüber hinaus kommt es vielerorts als Beschichtungsmaterial von Metallen oder anderen Polymeren zum Einsatz; beispielsweise in der Möbelindustrie, bei Spielwaren oder Helmen.
FREQUENTLY ASKED QUESTIONS (FAQ)
Yes, optical brighteners can help you move the wave light in such a way that the yellowish cast can no longer be recognized by the human eye.
Optical brighteners can be readily used during processing even when heated to decomposition temperatures. Optical brighteners are stable at the processing temperatures of industrial plastics.
