Exhibition Info - 27/12/2025Starlite exhibited its newly developed "BST-25S" at the N-Plus Product Development Technology Exhibition.

The BST-25S is a newly developed fire-resistant thermal insulation sheet for preventing the spread of fire in energy infrastructure facilities. It maintains the thermal insulation performance of ceramic-based thermal insulation materials while overcoming their inherent brittleness.
Product Feature

The BST-25S provides excellent thermal insulation, limiting the temperature on its backside to 100 °C even when exposed to a 1,000 °C flame for over two hours.
(Test results at 20 mm thickness. Thickness can be adjusted.)
Test Details and Results


The demand for preventing lithium-ion battery fires continues to grow steadily year after year. We are seeing a high volume of interest and inquiries across numerous fields, such as building materials, data centers, and the aviation industry.
The following are examples of facilities where thermal insulation would be useful:

Data centers

Battery transport containers

Battery storage facilities
Starlite will continue to provide products and services that contribute to the safety and security of society.
