Lintech Materials Introduces New Ultra-Soft, Energy-Specific, Flame-Resistant Thermally Conductive Pad
Lintech Materials Introduces New Ultra-Soft, Energy-Specific, Flame-Resistant Thermally Conductive Gap Filler Pad with 3.0 W/mK Thermal Conductivity and 31 Shore 00 Durometer
Lintech Materials TSP200 Thermally Conductive Gap Filler Pad
TSP300 is a soft, high performance thermally conductive gap filler pad with a thermal conductivity of 3.0 W/mK and a Shore 00 hardness of 31.
Outstanding thermal conductivity and very low distortion with very low outgassing provide an effective thermal interface between heat sinks and electronic devices where uneven surfaces, air gaps and rough surfaces and textures may exist.
- Available in a variety of thicknesses and finished in standard 10" x 15" sheets. Custom size configurations and die cut parts are available as individual parts or on sheets.
- And a range of high performance requirements such as high tack surfaces to reduce contact resistance Gap Pads; hot putty-like modulus; ultra-low deflection requirements; high thermal conductivity; RoHS compliance; UL 94 V-0 flammability rating and more.
- When burned at high temperature, it will form a hard protective shield to block and protect the remaining undamaged part of the new energy battery pack, avoiding the spread of thermal runaway, which will lead to the fire of the whole pack or even the whole vehicle.

Lintech Materials-explosion-proof ultra-soft thermally conductive gaskets for new640 new energy vehicle fires in 2022, up 32% year-over-year, higher than the average increase in transportation fires. It means that there are more than 7 new energy vehicle fires on average every day.
Lithium batteries are commonly used in the electric vehicle industry due to their high energy and high charge/discharge performance, with 18650 lithium batteries (18mm in diameter and 65mm in height) being the most common, but lithium batteries have an operating temperature limitation, and beyond the operating temperature, there will be a lack of charging and discharging efficiency as well as thermal runaway.
Take Tesla for example, this is the 18650 Li-ion battery module produced by panasonic:
Tesla's charging station uses 113.1ºF (45ºC) as the temperature wall, above which the charging power will be downgraded to keep the operating temperature within the temperature wall.
As batteries heat up more, the degree of unevenness increases, and high temperature batteries have a greater rate of material degradation than low temperature batteries, which generally requires controlling the temperature difference to less than 5ºC.
A Tesla Model S has 7104 18650 cells, and maintaining temperature uniformity across all 7104 at the same time is quite an undertaking.
Lintech Materials, as an expert in the development and production of structural adhesives and thermally conductive materials, was commissioned by a customer in the battery industry last year to provide a solution to the problem of thermal runaway (spontaneous combustion of batteries) and to provide a solution to the problem of battery safety and protection.
Lintech Materials TSP300 is a new energy specialized
Lintech Materials TSP300 Thermal Spacer for New Energy was born!
The TSP300 Thermal pad for New Energy has a unique patented design that transforms itself when exposed to high temperatures and immediately builds a thermal and fire barrier when the battery pack catches fire.
As a fire shield with both internal and external features, Lintech Materials TSP series of thermally conductive gaskets are widely used in new energy vehicle battery safety protection.
It is made of a combination of silicone rubber and a filler with excellent stability, which not only can weaken and block the deflagration heat flow by more than 50 times, withstand high temperatures of 1,200 degrees without melting, but also form a hard protective film at high temperatures, which can effectively block the heat from continuing to transfer to the inside.
Even if the battery spontaneous combustion
Can also effectively prevent combustion from spreading to the outside
Become the protective clothing of the battery
and is still thermally conductive.
We conducted a simulated thermal runaway battery fire test on this material:

【1300℃ Ultra-high Temperature Flame Impact】
Lintech Materials TSP Series Gasket - Flame Test 1After 1300℃ ultra-high temperature fire impact for more than 30 minutes, the special characteristics of the material are compatible with the glass fiber cloth on the back so that there is no breakage, cracking, or powder falling from the burning surface.
【1300 ℃ of ultra-high-temperature fire after more than 30 minutes of impact】
Lintech Materials TSP Series Gasket - Fire Test 2
The structure of the glass fiber cloth on the back side was intact, and the fire did not burn through the material.
It can be seen that the complete functionalized structure can play a very good role in flame retardant, fire resistance, fire impact resistance, heat insulation at high temperatures, and even withstand temperatures up to 1500℃.
Lintech Materials TSP series gaskets performed well in simulated fire impact tests.
The silicone rubber retains its properties at room temperature, but hardens at high temperatures to form a continuous, dense, functionalized film that transforms into a self-supporting inorganic rigid body.
The high temperature does not turn it into ashes, but helps it transform into a more fire-resistant hard protective layer!
And that's not all!
TSP Series has even more superpowers：
Low density material with light weight, applied to battery packs, it can reduce overall weight by 20% ~35%.
Weak flexibility and good fitting, assembled in the battery pack, can be bent, even at the folded corners, without special treatment, can be adhered to the battery pack
Ultra-high temperature resistance, heat insulation, with UL94 V0 flame retardant grade, can effectively slow down the thermal runaway of the battery pack.
has excellent aging resistance and can maintain stable performance throughout the product's service life.
meets the requirements of environmental protection and is REACH and RoSH certified, with no risk of dust fallout in the equipment workshop or during the life of the battery pack.
The all-around super power of this TSP super soft explosion-proof and flame retardant thermally conductive spacer provides the latest solution to the problem of thermal runaway (spontaneous battery combustion) in new energy vehicle batteries.
At present, this heat-conductive gasket has passed the test and verification of many new energy vehicle manufacturers and battery cell manufacturers, and has already obtained the invention patent, and the new energy vehicle industry chain is deeply integrated.
In the future, we will collaborate with more industries and continue to explore material innovation to create more possibilities for a better life.
