Take 100% control of your component manufacturing with PEAK-S3 & S5 Thinnest-Precision Silicone blank Sheets. Engineered with a 0.30 & 0.5 mm razor-thin profile and ±0.03 mm tolerance, these standard-preformed sheets serve as premium blanks for immediate in-house cutting lines. Designed with a proprietary anti-stick surface and completely stress-free flatness, they eliminate material distortion, allowing R&D labs and manufacturers to cut custom gaskets, membranes, and washers flawlessly without custom tooling overhead.
0.30 & 0.50±0.03 mm Thickness | 50 Shore A | 21 kN/m Tear | 8 MPa Tensile | -40°C to +200°C / +250°C (High-Temp)
Stress-Free Flatness: Transfer-molded resting stability prevents material warping or edge-curling during thermal and mechanical cutting.
Anti-Stick Formulation: Proprietary surface modification ensures effortless matrix peeling and clean component release after automated die-cutting.
Talc-Free Cleanliness: 100% clean, powder-free chemistry engineered for sensitive electronics, optics, and medical lab environments.
Availability Note: Our STD (Standard) Series sheets are maintained Off-the-shelf in 100-unit bundles for rapid fulfillment. To guarantee material freshness and peak performance, the Medical (MED) and High-Temp (HT) series are Made-to-Order.

To support advanced industrial environments requiring parameters beyond standard silicone physics, PEAK-S3 &S5 sheets are available in high-performance industrial elastomers:
SKU: PEAK-S3 & S5-NBR-STD | Nitrile Grade (Black) | In Stock
Engineering Focus: Premium fuel, hydrocarbon, and oil resistance for micro-automotive fluidic systems and industrial fuel seals.
SKU: PEAK-S3 & S5-EPDM-STD | EPDM Grade (Black) | In Stock
Engineering Focus: Exceptional UV, ozone, harsh chemical, and outdoor weathering defense for environmental micro-sealing.
Don't let rigid, pre-cut catalog components limit your engineering designs. PEAK-S3 &S5 High-Precision 100 x 100 mm ultra-thin silicone blank sheets are engineered as premium blanks, allowing manufacturing plants to instantly convert them into custom micro-components.
Our stress-free, anti-stick HCR technology unlocks critical solutions across four high-tech industries:
In biomedical and diagnostic hardware, fluid control at the microliter level requires ultra-responsive, bio-compatible barriers.
The Application: Custom-cut micro-valves, gas-permeable membranes, elastomeric pumps, and fluidic sealing layers for diagnostic cartridges.
Why PEAK-S3 & S5: Our 0.30 & 0.50±0.03 mm flatness ensures uniform sealing across complex micro-channels without clogging the fluid path. The talc-free, clean chemistry prevents sample contamination.
👉 Need Pre-Cut Testing Components? Check out our [ PEAK-08D-STD Series ] to verify our material performance in microfluidic valve environments before running your in-house cutting.
Modern smart vehicles, drones, and aerospace sensors require miniature seals that can withstand extreme environmental pressure without adding bulk or weight.
The Application: High-precision ultra-thin Gaskets, heat-resistant micro-seals, oil-resistant barriers, and environmental protection for optical sensors and outdoor camera housings.
Why PEAK-S3 & S5: With premium Solid Silicone 50A, NBR 50A, and EPDM 50A formulations, engineers can select the exact polymer path to resist extreme thermal cycles, oil exposure, or severe UV weathering.
As electronic components shrink, the demand for thin-profile electrical insulation and tactile dampening reaches a critical point.
The Application: Die-cut ultra-thin Washers (M2.5/M3/M4) for circuit board isolation, silicone spacer pads for membrane switches, and flexible protective layers for wearable device sensors.
Why PEAK-S3 & S5: Rolled silicone films are often too sticky to handle in electronic assembly. PEAK-S3 & S5 sheets feature a proprietary anti-stick surface, allowing automated digital plotters to peel clean, burr-free micro-washers that drop perfectly into automated surface-mount (SMT) assembly lines.
👉 No time for in-house laser setups? We also supply direct factory-stamped micro-washers. View our [ PEAK-W3-M3-STD Series ] with tolerances matching our premium sheet blanks.
Acoustic fidelity in high-end microphones, earphones, and smart speakers relies on the perfect elasticity of the vibrating diaphragm.
The Application: Delicate diagnostic instrument diaphragms, pressure-balancing acoustic membranes, and vibration-dampening rings.
Why PEAK-S3 & S5: Continuous-rolled films suffer from high residual stress, causing the material to warp after cutting. PEAK-S3 & S5’s transfer-molded process delivers a completely stress-free, resting flat sheet. This ensures the cut diaphragm maintains constant tension and predictable acoustic performance.
To achieve the absolute best tolerances (0.03 mm) when processing our ultra-thin silicone blank sheets, we recommend the following industrial methods. Yields up to 120+ micro-washers (e.g., M3 size) or custom microfluidic gaskets per sheet, reducing component procurement costs by up to 70%.
CO2/Fiber Laser CNC: Set to High Speed + Low Power in pulse mode. Because our sheets are inherently stress-free, the heat from the laser will not cause edge-curling or shrinking, yielding carbon-free, flawless edges.
Digital Blade Plotters / Die-Cutting: Use a high-tack cutting mat or vacuum bed with a sharp 60° carbide blade. The anti-stick surface allows the waste matrix to lift off cleanly without distorting fine geometries.
