Application and End-Uses

Green composites are applied to various components with moderate and high strength such as cars and mobile phones. Various problems associated with green composites include effects of moisture and humidity, strength reliability, enhancement in fire resistance, and so on. Moreover, there are some concerns over 

Some of the other areas in which the green composites are used are as follows false ceilings, partition purposes, doors, furniture, boxes for agriculture purposes, and so on. Other miscellaneous applications are rims, mobile panels, toys, aircraft, ships, and so on.

Because of the low level of emulsifiers and protective colloids, the suspension polymer types are most suitable for electrical applications and end uses requiring clarity, This form is also employed in the bulk of extrusion and molding applications. Cost is lower than for emulsion and solution forms. The emulsion or dispersion resins are employed mainly for organosol and plastisol applications where fast fusion with plasticizer at elevated temperature will occur as a result of the fine particle size of the resin. 

Control of Viscosity. To ensure that adhesives and sealants function well during their application and end use, the formulator must be able to control the flow properties of the product. The challenge that faces the formulator is that the adhesive or sealant may need different flow characteristics at different times. For example, adhesives must flow readily so that they can be evenly applied to a substrate and wet out the surface. Yet, there should not be an excess of penetration into porous substrates, nor should the adhesive run or bleed to create a starved joint. Certain adhesives and sealants must be capable of convenient flow application by trowel or extrusion, but they must also exhibit sag and slump resistance, once applied. Therefore, the flow properties, or rheology, of the material must fit the desired method of application. 

Substitution is a difficult task because the specific ingredients will control the application and end-use properties of the epoxy adhesive. Any substitution of material generally requires that the complete product be reverified with production and prototype testing. Of course, the health and safety issues of any alternative material must also be carefully considered to ensure that it is actually safer. 

In contrast to the liquid state, the crystalline state is relatively inelastic and rigid. For example, there is a difference of about five orders of magnitude between the moduli of elasticity in the two states. There are also major differences in other properties, including spectral and thermodynamic ones. Moreover, within the crystalline state it is possible to change properties by control of stmcture. This ability to control properties turns out to be of major concern in the application and end use of polymeric systems. 

In the production of monomers such as PDO and 1,2-PD, there are many patents that cover the chemistry and process of synthesizing these chemicals. The separation of these chemicals fi om the synthetic mix is another important area of technology (Malinowski 1999, 2000). There is patent activity, especially on the various new technolt es for the chemical synthesis of PDO that have lowered the cost of the monomer and opened it for more widespread application. There are also undoubtedly numerous patents on the formulation of the various polymers that contain PDO and 1,2-PD and the applications and end use...
