Key Features of Foamed Silicone ProductsFoamed 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: 1. Lightweight Structure with High CompressibilityThe 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.2. Thermal Insulation and Temperature ResistanceTrapped 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.3. Environmental and Chemical ResistanceRetains 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.4. Versatility in Cell StructureAvailable 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.5. Biocompatibility and Safety ComplianceNon-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.6. Mechanical Resilience and Shock AbsorptionDelivers 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.7. Electrical Insulation CapabilitiesOffers reliable dielectric properties, even in foam form, for use in insulating gaskets, pads, and housing in electronic devices and enclosures.8. Manufacturing Efficiency and CustomizationCompatible 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.3. parameters Foamed Silicone Products - Technical Specification TableCategoryItemValueGeneral InformationPlace of OriginChina (Zhejiang) Brand NameDachuang Kehua Model NumberAnti-static Foaming Processing ServicesMoulding, Cutting, Die-Cutting, Lamination| Physical Properties | Hardness | 16-20 Shore A | | | Density | 0.6 g/cm3 | | | Thickness Range | 2-40 mm | | | Surface Texture | Grid Pattern / Customizable | | | Cell Structure | Closed-cell (Obturator type) | | | Compression Set (22 hrs @ 70°C) | ≤15% | | | Tensile Strength | >700 kPa | | | Elongation at Break | >150% | | | Tear Strength | ≥15 kN/m (depending on density) | | | Recovery Rate | ≥98% after compression || Thermal & Electrical | Thermal Conductivity | 0.06 W/m·K | | | Operating Temperature Range | -60°C to +250°C | | | Peak Temperature Resistance | Up to +250°C | | | Electrical Resistivity | ≥10 Ω·cm (anti-static options available) | | | Dielectric Strength | ≥20 kV/mm (varies with thickness) | | | Flame Retardant Performance | Non-flame retardant (custom FR grades available) || Chemical Resistance | UV Resistance | Excellent | | | Ozone Resistance | Excellent | | | Water Absorption | ≤1% | | | Chemical Resistance | Good against mild acids, bases, and solvents | | | Oil Resistance | Moderate (custom grades for enhanced resistance) | | | Weathering Resistance | Outstanding || Workcraft & Customization | Machinability | Excellent for CNC cutting, die cutting, waterjet | | | Color Options | Customizable (natural, grey, red, black, etc.) | | | Surface Lamination | Optional adhesive backing, fabric lamination | | | Shape Customization | Sheets, rolls, die-cut parts, gaskets, seals | | | Certifications Available | RoHS, REACH, FDA (on request) |Our productionProduction Management Workflow1.
