Tensile strength values are typically measured on solution-cast films (ASTM D-412). These values may be higher than those from molded specimens.
Hardness (Shore A) values are typically measured on compression molded specimens.
Development products (MD, DX series) have properties that may change, and Kraton may discontinue production without notice.
"No flow" indicates that the polymer does not melt at 230°C or has extremely high molecular weight.
