Processing density

The cost/performance factor of individual surfactants will always be considered in determining which surfactants are blended in a mixed active formulation. However, with the recent advent of compact powders and concentrated liquids, other factors, such as processing, density, powder flowability, water content, stabilization of additives, dispersibility in nonaqueous solvents, dispersion of builders, and liquid crystalline phase behavior, have become important in determining the selection of individual surfactants. 

Bromine is often preferred as a FR source and, considering that most organo-bromine compounds are only 40-70 wt% bromine and that antimony trioxide is used in blends, FR-PBT blends may contain from 10 to 25 wt% FR additives. This high level of additives will have an effect on the melt processability, density and mechanical properties of the blend.

A final comment on the relationship between viscosity and density in this system should be made. It has often been claimed that a simple relationship exists between suspension viscosity and density in these process suspensions (e.g., reference 91). This has been applied to the calculation, rather than measurement, of process suspension viscosities based on easily measured process densities. The results of process measurements as shown in Figures 23 and 24 show that the actual relationship is more complex and depends on other process variables as well (67). 

The trend to higher densities or ciystallinities at higher temperatures and longer residence times. During SSP processing densities rarely exceed 1.42 g/cm, equivalent to a crystallinity of 70 vol% (according to the crystalline and amorphous densities given above).

Molecular volume This is a measure of density since there is an inverse relationship between density and volume. As will be seen in the analysis of various separation processes, density can be a significant variable. 

Besides the LHV a lot of additional quality aspects are relevant concerning biomass provision, storage, transportation and efficient conversion processes. Density and heat capacity, for example, are important parameters for unconditioned and for conditioned biomass. Particle density and particle-size distribution are of importance for chips and pellets, viscosity for liquid biomass.

Plastic-Plastic Separation Both dry and wet processes can be used to separate one plastic from another in a recycling operation. The most common wet separation methods are based on differences in density between particles of different plastics [1, 2, 10, 49], Density is a bulk property of the plastic. Unfortunately, many factors beyond polymer type affect density. Plastic particles can also show differences in surface properties. Plastic-plastic separation methods based on surface property differences include triboelectric separation [75] (a dry process) and froth flotation [75] (a wet process). Density-based and surface-property-based methods for separating a stream of mixed plastics are covered in the following sections.
