TIGER MARK FREE

Tiger mark : Visible flow defects characterized by alternating glossy and dull bands on the part surface,

approximately perpendicular to the flow direction

Longer distance from gate

More flow instability

More variability of rubber

elongation from shear strain

Higher Δ G between low

and high gloss zone
