Noryl EFR 735: halogen-free and flame resistant

Noryl EFR 735 is a halogen-free, flame resistant film which is manufactured of polyphenyl oxide. The flammability is confirmed according to UL94 VTM-0.

The Noryl EFR 735 film has an excellent temperature performance and meets the requirements of many electrical, electronic and transportation applications.

Noryl EFR 735 has an excellent dielectric strength and very good processing possibilities. The product can be deep drawn, coined, die-cut, formed and fold.

The film is available in thicknesses of 0.15, 0.25, 0.43 as well as 0.63 mm.

These days Noryl EFR 735 is only available in black.

EFR 735 is an excellent candidate for barrier- and insulating sheets, printed circuits, die-cut spacers as well as insulators, labels and covers.

The film is also well-suitable as an adapter for computers, laptops, mobile phones, portable devices, accumulators, DVD-players, printers, household devices, audio-/video devices and more electro and electronic applications.

  • V-0 / 0.25 mm

    UL approvals of Noryl EFR 735

    Noryl is listed with the UL file number E121562 and E207780.

    Many of our customers sell their electro motors, transformers and lightings to the United States. Usually there is a UL certification required.

    The speciality of the UL certification is the strong focus on single components as well as their technical, mechanical and chemical cooperation. The basic principle and the main idea of the UL certification are to minimise the risk for the customer.

    There are so-called UL recognized repacker for the coil-, electronic- and electro industry. Mostly these are converters which treat the materials produced of the manufacturer.

    This repackaging means that UL mainly certificates the products in the package and measurement with which they leave the particular production. If materials are coiled, die-cut or formed, they lose their UL certification.

    Because of our UL certification as a recognized repacker Noryl EFR 735 does not lose its certification.
