High-performance polymers for transport: safety, lightness and durability

Transport: multiple challenges for constrained environments

Against a backdrop of energy transition, the transport sectors - road, sea and rail - are looking for lighter, stronger and safer materials. High-performance polymers (HPPs) are increasingly replacing metals, with benefits in terms of weight, fire/smoke resistance, durability and corrosion resistance.

DEMGY supplies carmakers and equipment manufacturers with HPP injected, machined or 3D-printed parts, adapted to the specific standards of each mode of transport.

Why use HPPs in transport?

Weight reduction of up to 60% compared with metals
Compliance with fire/smoke standards: EN 45545 (railway), UL 94 V0, FMVSS 302
Shock, vibration, UV and moisture resistance
Electrical insulation, dielectric stability
Contract manufacturing: prototyping, production runs, tooling

Applications in various transport sectors

Rail transport: fire safety and sustainability

Key requirements:

EN 45545 standard (fire behavior, smoke and toxicity)
Resistant to vibration and moisture
Low maintenance and long life cycle

DEMGY solutions:

Injection-molded PEI and PPSU seat supports, covers, slideways
PEEK and LCP electrical components (dielectric stability)
Shock- and fire-resistant interior trim parts

Maritime transport: resistance to corrosion and saline environments

Challenges:

Resistance to salt, UV, chemicals and fluctuating temperatures
Lightweight and mechanical strength for on-board applications
Reduced maintenance costs

DEMGY solutions:

PEEK and PVDF crankcase, insulating sheaths
PA12 GF printed fasteners and conduits
LCP and PPS distribution board components

Automotive transport: lightness, safety and integrated design

Objectives:

Reduce emissions through lighter components
Compliance with FST standards and recyclability
Integration of functions (fastening, insulation, aesthetics)

Application examples:

LCP and PPS connectors, electronic housings
PEEK and PPSU battery / E-Mobility parts
PA12 GF and PEI hubcaps, motor covers, clip-on systems
Custom-machined thermal or electrical insulation systems
