DESCRIPTION
Elastollan C 85 A is a polyester based TPU

SPECIAL PROPERTIES
high tensile strength, excellent tear strength,
very good damping behavior, good rebound elasticity,
very good wear performance, good flexibility at low temperature
and resistance to hydrolysis

TYPICAL APPLICATIONS
technical parts, bellows, hoses, screen elements

OTHER HINTS
predrying: 2-3h at 100-110°C (air circulating oven)
or 80-90°C (dehumidified air dryer),
max. content of humidity before processing: 0,02%
annealing: 20 h at 100°C in order to get optimum properties
