Foamed Silicone: A High-Performance, Lightweight Elastomeric Material
This is a foamed material made from organic silicone. Compared to traditional foamed materials, it offers non-toxic and eco-friendly properties, excellent resistance to compression deformation and creep, as well as superior insulation and flame-retardant performance. Additionally, this material can withstand extreme temperatures, UV radiation, and ozone exposure while demonstrating outstanding mechanical fatigue resistance. It is an ideal material for various high-performance applications, including shock absorption, cushioning, sound insulation, protection, electrical insulation, and fireproofing.
It is a high-temperature vulcanized (HTV) foamed silicone rubber material characterized by low density, aging resistance, and exceptional high/low-temperature resistance (operating range: -55°C to 200°C), as well as flame retardancy (V-0 rating). It also features uniform foaming, high elasticity, excellent insulation properties, and is non-toxic and odorless.
Key Performance Characteristics
Excellent flame retardancy
Outstanding aging resistance
Exceptional high & low-temperature resistance (operating range: -55°C to 200°C)
Uniform foaming with high elasticity
Superior insulation, non-toxic & odorless
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.
