Although the Nylon 6/6 is the bobbin of choice for the audio transformer industry, EDCOR has taken this a step further to meet the class B 130 degrees C UL temperature classification. All of EDCOR's transformer bobbins are Nylon 6/6 GF-30, unless specified by the customer, and are RoHS compliant.
Nylon 6/6
Due to the combination of high temperature properties, toughness and resistance to chemicals, Nylon 6/6 accounts for approximately 43% to 50% of bobbins made industry-wide today. It is resistant to impacts, fuels, lubricants and most chemicals. And due to its electrical properties, it is widely used in the electronics field.
Nylon 6/6 GF-30 (glass-fiber reinforced)
All NYLON 6/6 materials have high mechanical strength and superior resistance to wear and organic chemicals, but NYLON 6/6 GF30 has more than double the strength and stiffness of unreinforced nylons and a heat deflection temperature which approaches its melting point. NYLON 6/6 GF-30 is a 30% glass-fiber-reinforced nylon 6/6 material whose important properties include high tensile and flexural strength, stiffness, excellent heat deflection temperature, and superior abrasion and wear resistance.
