What is a filler composite material?

Highly functional plastics containing fillers

A filler refers to a filling material.
Fillers that have various functions, such as thermal conductivity and electrical conductivity, are compounded with resins to formulate highly functional plastic materials that surpass the conventional limits.

Properties

Mixing fillers into resins to create a single material

Complementary functions and properties that cannot be achieved by a single material

A resin, which is used as the base material, is lightweight and easy to form.
Compounding with fillers that have various functions makes it possible to offer composite materials that take advantage of respective materials.

Familiar products in which filler composite materials are used

Filler composite materials are similar to pair skaters.

Pair skaters skate on the ice in splendid combinations.
They skate smoothly on the ice to demonstrate performances and support each other based on mutual trust. They are akin to filler composite materials. We will explain filler composite materials, which are completed by combinations of two materials, in analogy to pair skaters.

Filler composite materials

8 main functions

Thermal conductivity

Thermal conductivity

Smoothly transmitting and releasing generated heat

The Powder-Resin pair can warm them up quickly and demonstrate high performance in the competition. The heat of the warmed-up bodies can be released outside to cool down promptly.
Fillers with high thermal conductivity release heat and prevent the increase in the operating temperature of electronic devices, thereby contributing to a comfortable IoT society.

Electrical conductivity

Electrical conductivity

Electroconductive to transmit electricity effectively

The Powder-Resin pair transmits electricity by skating with a lightness of step, just like lightning.
Composite materials containing electroconductive fillers, such as metals, are used for antistatic materials and electroconductive rubber materials for sensors, etc.

Strength

Strength

Resistant to physical impact and will not break

The Powder-Resin pair has strong bodies and ties to successfully perform any difficult techniques.
The resin uniformly distributes physical pressure and absorbs impact. Thus, it demonstrates high impact absorbing performance. Composite materials with high mechanical strength can be offered by adding fibrous fillers, etc. to resins.

Light shielding performance

Light shielding performance

Dressed in black to block light

The Powder, which is dressed in black, absorbs and blocks light.
The carbon black material and structure characterized by high light absorbing performance demonstrate excellent light shielding performance.

Heat resistance

Heat resistance

Resistant to heat and will not melt

The Powder-Resin pair can withstand heat that melts the skating rink and does not give up.
Fillers are strongly bonded with resins and prevent resins from melting or being decomposed due to heat, thereby improving heat resistance.

Flame retardance

Flame retardance

Heat-resistant and will not burn

The Powder-Resin pair is resistant to blazing flames and demonstrates a passionate performance even in a hyped venue without any problem.
Composite materials containing flame-retardant fillers are fire-resistant and less likely to burn, thereby enhancing fire safety of various buildings and structures.

Gas barrier performance

Gas barrier performance

Repelling various gases and preventing transmission

The steps of the Powder-Resin pair are characterized by a regular rhythm and rotation and repel oxygen and other gases.
Ingress of gases is prevented by arranging fillers with special shapes, such as sheet-like fillers. Applications include food wrap films that do not transmit oxygen.

Adhesiveness/flexibility

Adhesiveness/
flexibility

Soft bodies that fit perfectly!

The Powder-Resin pair performs stretching every day and captivates spectators with flexible bodies that can perfectly keep any complicated poses.
Highly flexible filler composite materials can adapt to any uneven surfaces (shapes) and have high adhesiveness.

Applications of filler composite materials

Filler composite materials are formed into various shapes and used as heat release materials.

Applications of filler composite materials

Releasing heat from inside the batteries for electric vehicles

To ensure the life, safety, and stable performance of batteries for electric vehicles (EVs), filler composite materials help temperature control of batteries. Heat is generated through charging and discharging cycles, which may cause deterioration and fire. It is necessary to release heat from inside batteries and maintain an appropriate temperature.
