Cushion/Insulation Pad Aerogel

Introduction to Aerogel Insulation Pads: Aerogel insulation pads use an aerogel blanket as the central insulating material, surrounded by high-rebound silicone rubber and encased in a flame-retardant PET film, followed by heat-press sealing at the edges. This not only ensures that the silica aerogel does not fall out during use, achieving insulation and efficient thermal retention, but also provides cushioning and shock absorption, with a smooth and aesthetically pleasing surface.

Composition of buffer pads/thermal insulation pad aerogel

In the power batteries of new energy vehicles, aerogel buffer pads/insulation pads can be installed between battery cells. When a certain cell undergoes thermal runaway, these pads can effectively block the transfer of heat to adjacent cells, preventing thermal diffusion and avoiding the domino effect of thermal runaway in new energy vehicle battery cells. This greatly reduces the risk of vehicle-wide thermal runaway, providing more time for occupants to escape safely.

Aerogel materials: This is the core component. Aerogel is a porous material with a highly dispersed solid three-dimensional nanostructure, formed by the aggregation of colloidal particles or polymers, using gas as the dispersing medium;

Reinforcing fibers: In order to increase the strength and toughness of aerogels, making them easier to process and use, some reinforcing fibers are usually added, such as glass fibers, ceramic fibers, and pre-oxidized fibers. These fibers can form composite structures with aerogels, enhancing the overall mechanical properties.Binder: Used to bond aerogels and reinforcing fibers together to form a stable structure. Types of binders include acrylic polymers, flame retardants, fillers, etc., and they need to have good adhesive properties and high-temperature resistance.Encapsulation materials: Typically, encapsulation materials are applied to the outer surface of aerogel composite materials, such as PI (polyimide) films or PET (polyethylene terephthalate) films, to protect the aerogel, enhance waterproofing, and improve insulation. At the same time, they also facilitate the installation of cushioning pads or thermal insulation pads in application areas.

As a new type of underfloor heating material, PI heating film has the advantages of uniform heating, rapid temperature rise, and energy efficiency and environmental friendliness. Compared with traditional water-based underfloor heating, it is easier to install, space-saving, and can achieve intelligent temperature control. For example, in some small apartments or places with installation space requirements, PI heating film underfloor heating is a very good choice.

Advantages of buffer pads/thermal insulation pads with aerogel:

It can maintain the battery temperature within an appropriate range to ensure the battery’s performance, whether preventing the battery from overheating in high-temperature environments or ensuring normal battery performance in low-temperature environments (when the temperature is too low, the battery charges slowly and consumes power quickly). It plays an important role in thermal insulation and flame retardancy between power battery cells, thermal insulation and shockproofing between modules and the casing, and in the external cold-proof and high-temperature insulation layers of the battery box, thereby better achieving battery temperature control and electronic management.

  • Excellent thermal insulation performance: Aerogels have an extremely low thermal conductivity, ranging from 0.012 to0.024W/m·K,effectively preventing heat transfer. They are among the solid materials with the lowest thermal conductivity in the world. For example, using aerogel insulation mats in thermodynamic pipe networks can significantly reduce heat loss from the pipes and improve energy utilization efficiency;
  • Good cushioning performance: Aerogel insulation pads usually have a certain degree of elasticity and softness, which can provide cushioning when subjected to external impact, protecting the isolated objects from mechanical damage. For example, in the power batteries of new energy vehicles, they can not only prevent heat diffusion between battery cells but also mitigate the effects of expansion and contraction of the cells during charge and discharge on the battery structure during vehicle operation;
  • Ultra-lightweight: Aerogel is one of the solids with the lowest density in the world, making it extremely lightweight;
  • Environmentally friendly and non-polluting: Aerogel materials are mainly composed of inorganic components, making them environmentally friendly during production and use. They do not release harmful substances and meet environmental protection requirements.
