KEY
|
* These ratings give a general indication. Please ask about specific reageants |
|
+
|
The polymer is resistant. Any increase in weight is less than 2% and any decrease in weight is less than 0.3%. The tensile yield strength is at least 85% of the initial value. |
|
0
|
The use of the polymer is limited. Response does not meet above criteria. For example, weight increase might be more than 2%. However, the polymer can be used if stress is low. |
|
–
|
The polymer is not resistant. There is considerable alteration of the polymer, such as dissolution or chemical or physical degradation. |
