Solvay wins SPE Automotive Award for three lightweight material applications

Three electric vehicle applications using Solvay's specialty polymers have recently won the 2021 Society of Plastics Engineers (SPE) Automotive Awards
.
Among them, the injection-molded rotor slot liner made of Xydar LCP material won the first place in the "New Travel" category, and the KetaSpire PEEK material for enameled wire insulation won the second place in the "Enable Technology" category, using Ryton PPS coolant The pipeline took third place in the "Powertrain" category
.

Xydar LCP replaces multilayer films for cost performance

Specifically, the injection-molded rotor slot liner made of Xydar LCP material was developed and manufactured by Italian Cobraplast for a well-known German car manufacturer.

.

Used in rotor designs for advanced electric drive traction motors, this component provides a barrier between the rotor's copper windings and steel laminations
.
In this small but critical application, Xydar LCP replaces existing multilayer films and realizes cost performance advantages
.

According to reports, the material has very good flow and can fill 0.
65mm flakes in 220mm lengths with zero warpage to meet tight tolerance specifications
.
In addition, it ensures high stiffness to prevent breakage during assembly
.

KetaSpire PEEK material enameled wire insulation reduces motor weight and size

The enameled wire insulation made of KetaSpire PEEK material was developed by Essex Furukawa, Germany
.
Magnet wire coated with solvent-free KetaSpire PEEK material efficiently increases power density and torque while reducing motor weight and size
.

According to reports, this specialty polymer has thermal properties of 240°C and a dielectric strength of 197 kV/mm, as well as high ductility, stress crack resistance, long-term mechanical strength and good chemical resistance
.

Ryton PPS coolant line for high chemical resistance, mechanical strength and flame retardancy

Extruded coolant lines in Ryton polyphenylene sulfide (PPS) XE 3500 (unfilled) and XE 5430 (30% glass filled) with Ryton R4-270 (40% glass filled) injection molded connectors
.

Solvay said Ryton PPS is already widely used in cooling and ventilation lines in the high-heat environment of small internal combustion engines, and also provides the chemical resistance, mechanical strength and flame retardancy required for electric vehicle battery cooling lines
.

In these applications, specialty polymers replace lower-performing polyamides and metals, helping OEMs to benefit from plastic lightweighting when processing fluid systems with high chemical and mechanical performance requirements technology
