Foamed silicone is an engineered porous elastomer that combines the superior properties of silicone rubber with the advantages of a lightweight, cellular structure. Through advanced manufacturing processes-including chemical foaming, gas injection, or mechanical aeration-it develops a uniform matrix of air-filled pockets, creating a material that is:
30-70% lighter than solid silicone
Highly compressible (up to 80% deflection)
Thermally & chemically stable
Unlike conventional foams, foamed silicone retains the core benefits of solid silicone rubber, including extreme temperature resilience, UV/ozone resistance, and long-term durability-while adding critical cushioning, insulation, and sealing capabilities.
Operating range: -60°C to +250°C (short-term peaks to 300°C)
Low thermal conductivity (0.08-0.12 W/m·K) - ideal for heat insulation in EV batteries, aerospace, and industrial equipment.
UV/Ozone Proof: No degradation in outdoor exposure (ASTM G154 tested).
Chemical Inertness: Resists oils, acids, and solvents (compatible with IPA, diesel, etc.).
Waterproof Options: Closed-cell variants achieve IP68 sealing (submersion to 1m+).
| Type | Open-Cell Foam | Closed-Cell Foam |
|---|---|---|
| Structure | Interconnected pores | Isolated gas pockets |
| Best For | Acoustic damping, breathability | Waterproof gaskets, EMI shielding |
| Compression | High energy absorption (60-80%) | Low compression set (<20%) |
Compared to PU, EPDM, or PVC foams, foamed silicone delivers:
Higher temperature resistance (most plastics melt at 150°C)
Better chemical stability (no swelling in fuels/hydraulic fluids)
Longer lifespan (withstands years of compression cycles)
EV & Energy Storage: Battery cushioning pads, fire barriers (UL94 V-0).
Electronics: EMI shielding gaskets for 5G base stations.
Aerospace: Thermal/acoustic insulation in aircraft interiors.
Medical: Soft padding for prosthetics (ISO 10993-5 compliant).
Our proprietary self-foaming silicone technology eliminates traditional foaming agents, offering:
Density control: 0.05-0.5 g/cm³ (adjustable per application).
Zero VOC emissions - compliant with EU REACH.
Faster curing: 30% reduced production time vs. conventional methods.
Structured for Readability: Bullet points, comparison tables, and clear headers.
Technical Depth: Added quantitative data (temperature ranges, compression specs).
Market-Focused: Highlights competitive advantages vs. PU/EPDM foams.
Brand Integration: Showcases proprietary DC800 technology.
Foamed silicone is a specialized category of silicone elastomers, engineered with a cellular structure containing air or gas-filled pockets. This lightweight, semi-rigid or flexible material combines the core advantages of conventional silicone with enhanced cushioning, insulation, and weight-reduction properties. Produced through chemical foaming, gas injection, or mechanical aeration during curing, foamed silicone delivers performance-driven solutions across a wide range of industrial, consumer, and technical applications.
Below are the principal characteristics that define the performance and value of foamed silicone products:
The cellular composition significantly reduces material density, making foamed silicone ideal for weight-sensitive applications.
Offers excellent compressibility and recovery, allowing for reliable sealing, gasketing, and vibration isolation under mechanical stress.
Trapped air within the foam structure provides effective thermal insulation, minimizing heat transfer.
Maintains stable performance across a wide temperature range-from -60°C to +200°C or higher-without deformation or material degradation.
Retains silicone's inherent resistance to UV radiation, ozone, oxidation, and exposure to water and various chemicals.
Ensures long-term durability and material integrity in both indoor and outdoor environments, including industrial or corrosive settings.
Available in open-cell and closed-cell formats:
Open-cell foam offers breathability, sound absorption, and flexibility-ideal for cushioning and acoustic applications.
Closed-cell foam provides superior moisture resistance and is ideal for environmental sealing and thermal barriers.
Non-toxic, hypoallergenic, and available in medical- and food-grade formulations that comply with international standards (e.g., FDA, REACH, RoHS).
Suitable for sensitive applications including medical padding, infant care products, and food-contact insulation.
Delivers excellent shock absorption and damping performance, protecting components from mechanical impact and vibration.
Resistant to tearing, abrasion, and material fatigue-extending product life even under dynamic loading.
Offers reliable dielectric properties, even in foam form, for use in insulating gaskets, pads, and housing in electronic devices and enclosures.
Compatible with molding, extrusion, and die-cutting processes, enabling high-volume production and design flexibility.
Can be engineered in a range of densities, hardness levels, and colors to meet specific application and aesthetic requirements.
