Shenzhen Petersburg Composite Materials Co., Ltd

1. Ingredients & Manufacturing
Made from inorganic minerals: silicon dioxide (SiO₂), alumina (Al₂O₃) and calcium oxide (CaO) are the main components for excellent thermal stability.
Acupuncture process: special acupuncture technology is used to make the fiber winding to form a dense and uniform structure, so as to improve the mechanical strength and thermal insulation efficiency.
Optional heat treatment: Further roasting at 200-500°C to reduce smoke and odors creates a smoke-free version for eco-friendly applications.

2. Thermal performance
Excellent heat resistance:
Long-term operating temperature: up to 550°C
Short-term maximum exposure temperature: up to 700°C
Low thermal conductivity: Effectively reduces heat transfer and improves the energy efficiency of high-temperature equipment.
Dimensional stability: Retains shape and structure even when exposed to high temperatures for long periods of time without deformation or shrinkage.

3. Fire prevention and environmental protection
Naturally flame retardant: Inherently non-flammable meets Class A fire protection standards.
Smokeless and odorless: The post-bake process removes volatiles and eliminates smoke or odors during use, making it ideal for kitchen and indoor applications.
Environmentally friendly: free of asbestos and other toxic substances; Suitable for industrial and domestic environments.

4. Mechanical and chemical durability
High tensile strength: resistant to mechanical stress, vibration and handling.
Corrosion-resistant: Withstands moisture, oil, chemicals, and acidic or alkaline environments.
Long service life: Excellent aging resistance and fatigue strength, making it ideal for repeated thermal cycling.

5. Sound insulation and electrical insulation
Sound absorption: The porous fiber structure absorbs mechanical noise and airflow noise, improving the comfort of the equipment environment.
Electrical insulation: Provides a non-conductive barrier for use near electronic components and circuits.

6. Flexibility and machinability
Customizable Specifications:
Available in rolls for large-scale applications.
Available in die-cut or custom shapes for complex installations.
Lightweight and easy to install: Reduce labor costs and simplify insulation retrofits or repairs.

7. Common Applications
Household appliances:
Oven panels, microwave insulators, grill liners, and hob insulation.
Industrial Equipment:
Furnace doors, high-temperature pipes and kiln linings.
Filtration system:
It is a good alternative to traditional woven filter cloth.
Eco-friendly solutions:
It is used in environmentally friendly thermal insulation systems, where smokeless and odorless materials are essential.
