Electronic plastic

One of the aims of EU project Riskcycle is to assemble and evaluate existing information on the chemicals and especially the additives used in consumer and industrial products with a special focus on the fate and behavior of these additives in six product sectors textile, electronics, plastics, leather, paper, and lubricants [54].

Uses. About 35-40% of the methanol made is converted to formaldehyde. That s not because the embalming business is so good. Formaldehyde is a feedstock for amino and phenolic resins, which are used as adhesives in plywood, and in the automotive and appliance industry to make parts (all the agitators in washing machines used to be made out of phenolic resins). It is used as feedstock for hexamethylene tetramine, used in electronic plastics for pentaerythritol, used for making enamel coatings and for floor polish and inks for butanediol, a chemical intermediate and for acetic acid, which is widely used itself as a feedstock and solvent and warrants its own treatrnent later on. In the textile business, formaldehyde is used to make fire retardants, mildew resistant linens, and permanent press clothing.

The ability to ID black plastics is of secondary importance in the case of bottles but becomes more important for some electrical and electronic plastics and for many automotive plastics. Mid-infrared (MIR) can identify many black plastics but not near-infrared (NIR), where the carbon black interferes [19, 64, 65]. Recently, a company has reported success in applying laser Raman techniques to the rapid identification of black plastics [66]. 

Additional studies have examined the co-combustion of automotive shredder residue [47, 48, 111], electrical and electronic plastics [141-144], and building insulation foam [144] with municipal solid waste. Co-combustion of these plastics for energy production can also be carried out in compliance with U.S. and German waste-to-energy plant regulations in modem municipal solid waste combustors.

Until recently 96% of all discarded electrical and electronic equipment in Europe was landfilled. This amounted to about 14 kg of equipment per inhabitant every year, and the practice is now to be banned. All post-consumer electrical and electronic products will have to be collected and subjected to specific disposal procedures. The WEEE Directive (2002/96/EC) (February 2003) requires the manufacturers of electrical and electronic equipment appliances to bear the cost of recovery and recycling. It is intended to ensure the recovery of 300,000 tonnes of electrical and electronic plastics waste material per year by 2006, the date by which each member state should be collecting 4 kg per inhabitant by separate collection procedures.

This term is also sometimes called permittivity. Dielectric constant values have no units because they are mathematical ratios. Low dielectric constant values, desirable for electronic plastics, would be below 3.0 or 4.0. 

Quantitatively, lower dissipation factors result in higher-quality, higher-performance electrical or electronic systems, having lower electrical losses. Dissipation factor values have no units because they are mathematical ratios. Low dissipation factor values, desirable for electronic plastics, would be below 0.01 and 0.001. Two other terms for dissipation factor are loss tangent and tan delta. A related term is quality factor or Q factor, which is the reciprocal of the dissipation factor.

For high-performance electronic plastics, it is desired that the volume resistivity exceed 10 ohm-cm. One other term used to describe the resistance characteristics of an electronic plastic part, such as a circuit board or connector, is insulation resistance. This is simply the resistance, in ohms, between two conductors that are embedded within the plastic part.
