Detailed

Description:

 

KA-P101 is a colorless clear double component polyether polyurethane for tire, with good abrasion
resistance, yellowing resistance, resilience. It can cast at normal temperature, and suit for assembly line
production . The performance slightly worse than polyester polyurethane, but more easy to work. So far
most of tires are made from polyether polyurethane .

 


Composition:
Part-A component: polyol,
Part-B component: Isocyanate-terminated prepolymer.

 


Application area:
For the production of skateboard wheels, skate wheels, skate wheels, tires,etc.

 


Storage:
Storage in a cool and dry place.
