Nylon 6, 66 ( UBE, SRF,BASF)

Nylon (PA) 6 & 66 are both synthetic polymers called polyamides, with the numbers describing the type and quantity of polymer chains in their chemical structure. Most nylons, including 6 & 66, are semi-crystalline and possess good strength and durability for demanding applications.  

Nylon 6, 66 ( UBE, SRF,BASF)

Nylon 6 & 66, whilst having their own separate and distinct benefits, do share many of the same core properties:
