 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 audio transformers industry, EDCOR has taken the a step further to meet the class F 155° degree UL temperature classification. All of EDCOR Electronics transformer bobbin are Glass Fill Nylon 6/6, unless specified by the customer, and are RoHS compliant.
Due to it’s combination of high temperature properties, toughness and it’s 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 electronic fields.
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 it brings the material to a class F 155° degree UL temperature classification.
