Attention High Voltage
Signal Colors with Low-Halogen Controlled Pigments
The company for specialty chemicals Clariant AG, Muttenz, Switzerland, presented recently their low-halogen controlled pigments "warning orange" for coloring high voltage components of electric and hybrid vehicles.
As recommended by the Society of Automotive Engineers (SAE International) and The German Electrical and Electronic Manufacturers’ Association (ZVEI), orange has become critical color coding for identifying high voltage systems. China Highway & Transportation Standard QC/T 1037-2016 also stipulates eye-catching orange for high voltage cables in road vehicles.
According to the manufacturer the pigments offer a new low-halogen option for creating the typical strong orange shade for automotive charging cables, connectors, sockets and switches, without noticeable impairment of electrical properties. Importantly, they can support component manufacturers in following the new European regulation for halogen-free electric vehicle charging cables - DIN EN 50620:2017-11.
High Heat and Chemical Resistance
For charging cables in electric vehicles PV Fast Orange H2GL-LHC is offered.. It is a pure mid shade orange pigment with high heat and chemical stability that makes it suitable for commonly-used Thermoplastic Elastomers (TPEs). Its high color fastness means that it does not migrate or rub off onto neighboring materials while high lightfastness ensures that the cables remain visible for many years.
PV Fast Orange 6RL-LHC is a reddish orange pigment ideal for identifying high voltage in electric vehicle charging systems including connectors, sockets and MD switches. It has high heat and chemical stability that makes it suitable for coloring engineering polymers, in particular Polybutylene Terephthalate (PBT) and Polyamides (PA) used in charging connectors. Furthermore, it has a proven ability to not negatively influence halogen-free flame retardant performance. It achieves UL94 V-0 at 0.8mm with halogen-free flame retardants in engineering plastics and ensures compliance with RoHS 2.0 and IEC 61249-2-21. The colorant has good color- and lightfastness properties.
In addition to its warning orange shades, Clariant offers its PV Fast Pigments with good weather-fastness and high chroma. They open up opportunities to create more appealing, colorful Polycarbonate (PC) and Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) housing for electric vehicle charging stations and piles.
