Technical Materials For Automotive & EV Applications
Automotive applications range from Engine management systems to motor drive controllers and they often need custom-made gaskets and pads in a wide range of technical materials.
Technical Materials used in the automotive and EV industry include Thermal interface pads, environmental Gaskets, RFI shielding pads, Electrical isolation, adhesives, optical films, and vibration damping to name just a few.
Materials Direct work with some of the industry’s renowned brands to bring you the highest quality materials and made exactly the design of pad or gasket to suit your application.
Commonly Sourced Materials in Electric Vehicle Applications
Electric Vehicle (EV) applications include nearly everything that is not the battery cell itself in a Battery Pack. Materials include the Lithium-Ion cell carriers called UniFoam – an extremely lightweight stiff foam material giving mechanical stiffness and support to the cells themselves.
UniFoam has the advantage of Vibration damping, fire retardancy, and accurate complex shapes can be achieved. A range of dedicated fire retardant materials called Fire protection films are available which snuff out any potential thermal run-aways.
The Importance of Thermal Interface Materials
Thermal Interface Materials such as Thermal Pad T-Pad and UniGap from Universal Science are supplied to the battery manufacturers as rapid charging and discharging heats the battery sometimes to unacceptable levels.
The TIM will remove the unwanted heat build-up by conduction cooling to cold walls or heat-sinks often utilizing liquid cooling.
The supply of high breakdown voltage and very high thermal conductivity TIM materials from DuPont called Kapton MT+ is a new addition to their Kapton material range. A full PPAP and IMDS can be supplied to support the Automotive industries.
EMI-RFI shielding materials are also required in the casing or housing of the batteries as often a large amount of electrical energy is being handled which can cause unwanted emissions of EMI.

Thermal Interface Materials
As batteries for electric vehicles become smaller and more performant, they also produce more heat which must be dissipated safely.
Thermal Interface materials allow design engineers to create better designs with more complete thermal management, starting at the device level.
Tapes & Adhesives
We supply a wide range of Tapes and Adhesives to the Automotive industry.
They can be used for a wide variety of applications including installation, repair, insulating, reinforcement, bonding, chemical and paint masking, and erosion protection.
Sealing Gaskets
We offer a wide range of sealing gasket materials, custom cut to meet a wide range of applications.
Seals and sealing gaskets play an essential role in both motor and electric vehicles.
LED Optical Materials
With automotive and electric vehicle requirements for reliability being exacting, LEDs and components need to meet stringent demands.
We offer a range of materials that help you to enhance the performance and durability of your LED lighting assemblies.
EMI / RFI Shielding
As technology advances, more devices emit Electromagnetic interference. Automotive, EV, and other transportation electronics can be affected by harsh external EMI environments.
A wide range of our technical materials deliver high-quality EMI / RFI shielding to your applications or can be specially coated to do so.
Electrical Insulators
The energy used in electric vehicles is stored in high-voltage batteries that must have perfect electrical insulation to ensure the energy source is not compromised.
Materials Direct offers an extensive range of electrical insulation materials suitable for automotive and EV applications.

Frequently Asked Questions
What materials are commonly used in the Automotive and EV sector?
Similar to Aerospace the Automotive industry has a requirement for high reliability materials to protect electronics systems in a vehicle. The Automotive electronics include motor drive applications, the numerous systems these days for driver assist, lane keeping to engine management and telemetry. They include thermal interface materials to cool electronic enclosures which are often crammed with electronic devices needing to rid themselves of unwanted heat. Other materials such as Radio frequency interference is required so as to prevent cross-talk or radio interference between electronic systems. Gaskets and seals are needed to protect your electronics. Lightweight materials are supplied by materials direct to house Lithium Ion batteries and other supporting materials towards building batteries or energy storage. Plastics that need to be cut to size and maybe formed are also available from materials direct. Plastics that are as simple as a washer to a complex cover or chassis are supplied by materials direct with ease.
Do you provide technical materials suitable for all Electric vehicles, including mopeds etc?
Materials Direct offers solutions for battery manufacturers and energy storage mostly for the structural parts of the batteries, pretty much everything that is not the battery itself in the battery system.
What are Material Directs Environmental Values and what systems are in place to improve sustainability?
Materials supplied are checked for their environmental impact and we provide Rohs and Reach certification to assure no harmful chemicals are present.
