Brief Introduction :
Truly endless, heat resistant ,needled felts have been developed for use in extremely high temperature applications. They are widely used throughout the aluminium extruding process , as a substitute for wood strip and plumbago .These materials possess a unique combination of characteristics including excellent resistance to prolonged high temperature exposure , excellent abrasion resistance and a smooth surface which does not scratch aluminum profiles .
Tension Members
Normally there three types of tension members used in felt belts
Kevlar K :
Temperature resistance :500℃（short contact）
Strength :25N/mm at 1% elongation
Nomex N
Temperature resistance :250℃（short contact）
Strength :10N/mm at 1% elongation
Polyester P
Temperature resistance :200℃（short contact）
Strength :15N/mm at 1% elongation
