The type of bobbins EDCOR uses to wind coils on.
Below is a summary of some of the mainstream plastic bobbins used in the transformer field. 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 degree UL temperature classification. All of EDCOR's transformer bobbins are Glass Fill Nylon 6/6, unless specified by the customer, and are RoHS compliant.
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.
Glass Filled Nylon 6/6
This is basically the same as the Nylon 6/6 with the addition of 30%-35% glass fibers. The addition of glass fibers allows a higher heat deflection temperature and brings the material to a class B 130 degree UL temperature classification.
