Sheet material for sealing, cushioning and insulation
Cut-to-size sheets and drawing-based processing review. View processing options →
AITO supplies silicone foam sheet material for converters making gaskets, cushioning pads and insulating interfaces. The series covers nominal densities of 160, 190, 240, 280, 370, 420 and 500 kg/m³.
Published 25% compression stress ranges from 8 ±5 to 120 ±30 kPa across the seven grades. Select the compression response and thickness around the available space and assembly load.
The listed service-temperature range is −60 to +200 °C. Review the selected grade and construction under the actual operating conditions.
Compare density, compression stress and available thickness. Open a product for the complete reference data.

AITO supplies silicone foam sheets with processing requirements reviewed against the selected grade, thickness and component drawing.
AITO processing services: Grooving, slitting, lamination, CNC cutting, waterjet cutting, wire cutting, oscillating-knife cutting, strip cutting, cut-to-size work and die cutting.
The cutting method is selected for the material, thickness and drawing. Confirm feasibility for the selected silicone grade. Raw-foam temperature, fire and electrical data do not automatically apply to an adhesive-backed or laminated part.
Thicknesses start at 0.5, 0.8 or 1 mm depending on the grade, up to 30 mm. Standard widths are 500 and 1000 mm.
Send the required length, dimensional tolerances and quantity. Include adhesive or lamination requirements for supply review.
Sheet material for converters producing seals, cushioning pads and insulating interfaces.
Foam strips and frame gaskets can be evaluated at pack covers, service openings and enclosure joints. Specify the installed gap, fastening load and sealing requirement. The finished assembly needs its own sealing and safety validation.
Converters cut the sheet into seals for doors, lids and removable access panels. Select the starting thickness and compression response around the enclosure fit, then review the bonding surface and joining method.
Pads and interface strips can separate contacting parts in vehicle assemblies. Review contact area, movement and compression load together; the sheet data does not define a finished-part vibration rating.
Silicone foam can be evaluated for cushioning, insulation and protective interfaces in rail and energy-storage equipment. State the required fire, smoke and toxicity specification so the relevant grade, thickness and test report can be reviewed.
The number is the nominal density in kg/m³. It is not a hardness value. Check the separate 25% compression stress when reviewing assembly force.
SIL-160 and SIL-190 list 1–30 mm. SIL-240 and SIL-280 list 0.8–30 mm. SIL-370, SIL-420 and SIL-500 list 0.5–30 mm. Standard widths are 500 and 1000 mm; confirm the required length and tolerances.
Send the sheet size, thickness, quantity and any adhesive or lamination requirements. AITO supplies the material for your subsequent cutting and assembly process.
State the exact standard, required classification and material thickness. Review the applicable test report for the selected construction before approving a production part.
The supplied reference lists a test at 100 °C for 22 h under 50% compression and a result of ≤5.0. It does not state the result unit or recovery procedure. A defined compression-set value must be confirmed before specification.
