FEATURES
CWB-914/915/918 provides soft and flexible properties to the mat with sufficient strength.
CWB-914/915/918 is excellent in penetrating effect for the process resins, provides transparency to the finished product and excels in boiling water resistance.
In the course of spattering process at the factory, CWB-914/915/918 easily slips down through the hopper on the traversing chopped strand layer below because of its antistatic and free flow features.
CWB-914/915/918 can be easily dispersed in water.

STORAGE
CWB-914 should be stored out of sun below 30℃.
CWB-915/918 should be stored out of sun.
