Incompatibles table

More recently, somewhat incompatible systems with a-methylstyrene copolymers, ethylene-vinylacetate resins, and paraffin wax (13) have shown exceptional hot tack although the blend is clearly incompatible. Table III shows that the adhesion increases with the cloud point of the blend. 

The coefficient of linear thermal expansion was measured in specimens according to dental standards. The value of 10.6 X 10 recorded for IPS EMPRESS 2 compared with 15.0 X 10 K for IPS EMPRESS , clearly shows that the two materials are incompatible (Table 4-17). As a result, two different sintered ceramics must be used for the two systems of materials. 

TABLE 11.50 Some Common Reactive and Incompatible Chemicals... 

Chemical incompatibility charts can help in organizing available data on the incompatibilities existing between expected mixtures. Frurip (Frurip et ah, 1997) gives one procedure for developing a chemical compatibility chart while describing some of the tools available. CCPS G-13 also provides a table of known incompatibility hazards. 

Such linking enables two distinct polymers which are normally incompatible to mix intimately. As a result, the properties of blends of such materials may be markedly improved, as shown in Table 7.9. 

Table 7.4 Toxic hazards from incompatible chemical mixtures...

Protective measures against bimetallic corrosion should ideally start before the particular installation or equipment is built . Reference should be made to tables showing compatibility of metals, alloys and non-metallic materials (5 Table 1.25) and to the literature. However, it must be emphasised that the environment obviously plays a most important role in bimetallic corrosion, and that there are a number of situations in which apparently incompatible materials in contact can be used without adverse effects. 

It has been known for more than a century that human blood can be classified into four blood-group types (A, B, AB, and 0) and that blood from a donor of one type can t be transfused into a recipient with another type unless the two types are compatible (Table 25.1). Should an incompatible mix be made, the red blood cells clump together, or agglutinate. 

Undesirable emissions of toxic gases may occur as a result of mixing relatively common chemicals. Refer to Table 6.4. Chemicals which are incompatible in this way must be brought into contact only under strictly controlled conditions. 

Many chemicals are incompatible because a violent reaction may occur on mixing. This can, in some conditions, result in an explosion. Refer to Table 6.5.
