“In terms of properties and
processing, our new materials are on par with, or even superior to, their
counterparts containing halogen-based flame retardance packages. We believe
that sales of these products will benefit in the future from global trends,
such as Industry 4.0, electromobility and digitally networked building systems,
household devices and consumer electronics,” explains Alexander Radeck,
applications developer in the LANXESS High Performance Materials (HPM) business
New additions to the Pocan BFN
PBT product line, which previously encompassed materials with 13, 25 and 30
percent glass fibre reinforcement, include Pocan BFN2502, BFN4221 and BFN6410.
Pocan BFN2502 is a non-reinforced material that displays a high elongation at
break of over seven percent despite its halogen-free flame retardance package.
It passes the UL 94 standard fire tests of the U.S. testing organization
Underwriters Laboratories, achieving the best classification of V-0 (0.4
millimeters). Another advantage is its high tracking resistance of 600 volts
(CTI A, Comparative Tracking Index, IEC 60112). “We see good opportunities for
this easy-flow material in components requiring high-level, consistent
electrical insulation properties and high dimensional stability,” Radeck adds.
Pocan BFN4221 has a glass fibre
content of 20 percent. Like its “sister products”, this compound displays not
only high flame retardance attributable to a low tendency toward corrosion in
contact with metals, but also good thermal aging resistance and colour
stability at elevated temperatures, a wide processing window and good
suitability for high-contrast laser marking.
Tailored to LED technology
Pocan BFN6410 targets
applications in lighting and LED technology. Radeck: “Its light reflection of
more than 94 percent at 450 nanometers is unusually high, meaning that when
used as a housing material, it reflects LED light almost entirely.” It also
offers high blue light resistance and high lightproofness even at thin wall
thicknesses. The material further displays good mechanical behavior and a low
tendency to warp. It achieves the best classification in UL 94 fire testing of
V-0 (0.75 millimeters).
