Blog - DP Silicone | China Manufacturer of Seals, Gaskets, Insulation, dpsilicone, silicone foam, liquid silicone foam, special silicone products.

Silicone foam is mainly made of silicone rubber raw material, supplemented with fillers (such as white carbon black), vulcanization accelerators, foaming agents and other auxiliary materials. After mixing evenly, it is made through high-pressure and high-temperature foaming process. Its microstructure presents a porous honeycomb like structure with a density as low as 0.16-0.45 g/cm ³ (matrix density 1.17 g/cm ³), forming a polymer elastomer with both elasticity and lightweight properties. ‌

Foaming technology: including chemical foaming (decomposition of hydroxyl foaming agents to produce gas) and physical foaming (expansion of organic foaming microspheres).
Special modification processes: such as UV light curing, plasma treatment, flame retardant compounding (aluminum hydroxide/spherical silicon composite flame retardant), etc.
Structural control: By adjusting the cell size through the use of a foaming agent and process parameters, closed cell/open cell structural design can be achieved.

Mechanical properties: Compression rebound rate>90%, adjustable hardness range 20-80 Shore C.
Thermal performance: Temperature resistance range -100 ℃~350 ℃, thermal conductivity coefficient 0.4W/m · K.
Electrical performance: Volume resistivity>10 ΩΩ· cm (unfilled), increasing filler will reduce insulation.
Environmental tolerance: resistant to UV aging (no obvious cracking after 3000 hours), waterproof rating IPX7, resistant to ozone concentration above 50pphm.

structural classification

Closed cell type: mainly composed of independent bubble structures, suitable for sealing and insulation (such as sealing gaskets for new energy battery packs)
Open hole type: connected hole structure, good at sound absorption and shock absorption (such as interior materials for rail transit)
Hybrid type: combining the characteristics of both, used for special buffering scenarios

Industry application cases

New energy vehicles: battery pack cushion (density 0.2g/cm ³), motor compartment insulation layer
Electronic appliances: PCB conductive shielding foam (surface resistance<0.1 Ω/sq)
Aerospace: cabin sound insulation materials (noise reduction coefficient NRC ≥ 0.8)
Medical equipment: Medical mattress (certified with ISO 10993 biocompatibility)
