Product Description
The KB1020MF silicone micro-foam is a lightweight, high-strength material with adjustable cell expansion ratios, widely used in industries requiring specialized compression stress performance. It is eco-friendly, non-toxic, and odorless, offering excellent fire resistance, flame retardancy, low smoke density, and low smoke toxicity. The material provides superior weather resistance (UV and ozone), temperature stability across extreme conditions (–60°C to 200°C), and outstanding electrical insulation properties.
Low compression set and high creep resistance
Excellent flame retardancy, low smoke density and toxicity, high oxygen index
High electrical insulation
Wide operating temperature range, capable of continuous operation from –60°C to 200°C
Environmentally friendly with low VOC emissions

Closed-cell silicone foam is used in a wide range of industries for sealing, insulation, cushioning, and flame protection. Its closed-cell structure prevents the passage of air, water, and dust, making it ideal for environmental sealing in harsh conditions. Common applications include:
EV battery pack protection and sealing
Thermal insulation and fire protection in energy storage cabinets
Gasketing in automotive and aerospace systems
Shock and vibration dampening in electronic devices
Weatherproof seals for outdoor equipment and enclosures
Because of its excellent temperature resistance, low compression set, and flame-retardant performance (UL94 V-0), it is trusted in critical and high-safety applications.
Features a compact structure where cells are completely enclosed, preventing air, water, and dust from passing through. This makes it ideal for sealing, insulation, and environmental protection in harsh conditions. It offers better water resistance and lower air permeability, commonly used in EV batteries, outdoor enclosures, and gaskets.
Has interconnected cells that allow air and moisture to flow through. It is softer, more compressible, and better for cushioning, sound absorption, and applications requiring ventilation or breathability.
Closed-cell: Better sealing and protection
Open-cell: Better breathability and cushioning
Choosing the right type depends on your application’s needs for moisture control, airflow, and mechanical performance.
