Shenzhen Petersburg Composite Materials Co., Ltd

Our high-temperature fiberglass needle felt insulation is designed for harsh thermal environments. It is mainly composed of inorganic minerals such as silica (SiO₂), alumina (Al₂O₃) and calcium oxide (CaO), which have excellent thermal stability and mechanical strength.

1. Ingredients and manufacturing process
Inorganic mineral substrates: Provides excellent heat resistance.
Acupuncture process: Forms a dense and uniform fiber structure to improve thermal insulation and strength.
Optional heat treatment: Hot roasting at 200–500°C removes smoke and odors, making it suitable for environmentally friendly applications.

2. Thermal performance advantages
Long-term operating temperature: up to 550°C
Short-term exposure temperature: up to 700°C
Low thermal conductivity: Effectively blocks heat conduction and improves energy efficiency.
Dimensional stability: no deformation or shrinkage in a long-term high temperature environment.

3. Fire and environmental features
Natural flame retardant: Meets Class A fire protection standards and is inherently non-combustible.
Smokeless and odorless: No odor and volatile substances after heat treatment, suitable for kitchen and interior.
Eco-friendly material: free of asbestos and harmful substances, suitable for industrial and household use.

4. Mechanical and chemical durability
High tensile strength: Withstands shocks, vibrations and repeated operation.
Strong corrosion resistance: Resist chemical attacks such as moisture, oil, acid and alkali.
Long life: Excellent resistance to aging and heat cycling.

5. Sound insulation and electrical insulation
Sound absorption and noise reduction: The porous structure absorbs mechanical and airflow noise for increased comfort.
Electrical insulation: Non-conductive, suitable for use around electronic components.

6. Flexibility and processability
A variety of specifications are available: coils are available, suitable for large-area construction; Support die-cutting and customized special-shaped parts.
Lightweight and easy to install: Reduce construction difficulty and labor costs, and facilitate transformation and maintenance.

7. Common application scenarios
Household appliances: oven panels, microwave oven insulation panels, grill liners, stove heat shields.
Industrial equipment: furnace doors, high-temperature pipes, kiln linings, etc.
Filtration System: A premium alternative to traditional woven filter cloth.
Environmental protection project: It is suitable for energy-saving and environmental protection systems with high demand for smoke-free and odorless.
