    Cable harnesses are one of the most complex components in an electric vehicle
    .
    Not only must their many connectors be colour-coded to represent a range of functions and support assembly and maintenance, but they must also be highly flame-retardant and mechanically strong

    .
    With the polyamide 6 compound Durethan BKV30FN04, LANXESS has developed a material for these connectors that has been tried and tested in many series of applications - including cable harnesses for electric models produced by a European-American car manufacturer

    .

    "Compared to polyamides which are flame retardant with red phosphorus, our halogen-free flame retardant compounds can also be dyed in bright, vivid colors such as orange (RAL 2003) and Yellow
    .
    This compound and colour exhibit a high degree of thermal stability, which means that the different connectors can be easily and reliably distinguished over the entire service life of the vehicle

    .
    ” The connectors are produced in Heilb, Germany It is produced by Amphenol Tuchel Electronics Co.
    , Ltd.
    in Long, a subsidiary of the American Amphenol Group, one of the world's leading manufacturers of electrical connectors

    .

    All colors have passed the UL yellow card certification

    All colors have passed the UL yellow card certification

    LANXESS' polyamide 6 compounds are characterized by excellent flame retardant properties
    .
    In the UL 94 flammability test by the American testing agency Underwriters Laboratories Inc.
    , it achieved a V-0 rating (test body thickness: 0.
    75 mm)

    .
    “All our color compounds are UL Yellow Card certified, which also includes colors like yellow, orange and blue

    .
    This means that processors won’t have to color products themselves or go through the time-consuming UL certification process

    .
    They Our pre-coloured compounds can simply be used as is, which helps cut costs

    ," says Bernhard Stoll
    .

    Tough, high-performance material

    The cable harness is distributed along the entire length and width of the car, bundling all the different on-board power cables for power and electronic units such as power converters, battery charging systems, electric drives and infotainment systems
    .
    The total length of the cable can reach several kilometers, which is one of the reasons why the cable harness is so heavy

    .
    The complexity of the cable harness makes it an extremely expensive component, which is why the connector cannot break during installation

    .
    "Our compound is very strong and tough, which means the connector can easily withstand bumps or drops," Stoll said

    .
    Thermoplastics are highly chemically resistant, which means that their strength and stiffness are very strong in contact with electrolytes or Coolant is hardly affected

    .
    It also exhibits excellent tracking resistance, achieving a CTI (relative tracking index, IEC 60112) value of 600 in orange

    .

    Wide processing window

    Wide processing window

    Durethan BKV30FN04 is not only used in connectors in the field of electric vehicles, but also in signal transmission technology and industrial engineering
    .
    Bernhard Stoll: "Here, our compound has also proved suitable for injection moulding within a stable processing window

    .
    The flame retardant additive of the material hardly leaves any deposits in the mould, which helps ensure relatively Long tool life and efficient production

    .
    ” And when it comes to occupational safety, this polyamide 6 is easier to handle than its flame-retardant equivalent compounds
