Can Fiberglass Sound Insulation Cotton Work Normally in High-Temperature Environments?
Dec 18, 2025| Fiberglass Sound Insulation Cotton can work normally in high-temperature environments.
Its core material is fiberglass, which has good high-temperature resistance. Regular products can withstand continuous high temperatures of around 200℃, while some industrial-grade products have a higher temperature tolerance limit. In high-temperature environments, its structure will not deform easily, and its core sound-absorbing and noise-reducing performance will not decay significantly.
It should be noted that different specifications of Fiberglass Sound Insulation Cotton have different maximum temperature resistance limits. When purchasing, you should select products that match the actual ambient temperature of the application scenario. At the same time, avoid exposing the product to extreme high temperatures far exceeding the rated value for a long time, to prevent aging of the outer protective materials and avoid affecting the service life.
As long as Fiberglass Sound Insulation Cotton is used strictly within its rated temperature range, it can maintain good performance for a long time in high-temperature environments.
