Transparent Silicone Sheet
ElastaPro makes transparent silicone in food, medical, and medium strength grades. Transparent silicone sheet is a high‑purity, platinum‑cured elastomer engineered for applications that require transparency: a material property that allows light to pass through with minimal absorption or scattering so that objects on the other side are visible.
Important: These solid silicone sheets are not optically clear; however, they provide excellent visual clarity, making them ideal for environments where operators must inspect fluid paths, gasket alignment, or component interfaces.
ElastaPro manufactures transparent silicone sheets in a wide range of thicknesses, durometers, and formats—including continuous rolls—to support both prototyping and high‑volume converting. Because they are platinum-cured, these materials are free from peroxide by-products. They maintain their transparency over time and resist yellowing, haze, and environmental degradation.

- High‑purity gasketing and diaphragm components
Transparent Silicone vs. Translucent Silicone
Transparent silicone allows light to pass through without scattering, letting you clearly see objects on the other side. Translucent silicones also let light pass, but they scatter it so that the view behind them is blurry or indistinct.
| Property | Transparent Silicone Sheet | Translucent Silicone Sheet |
| Optical Clarity | High transparency | Cloudy, light‑passing |
| Cure System | Platinum‑cured | Peroxide or platinum |
| Extractables | Very low | Low–medium |
| Visual Inspection | Excellent | Limited |
| Typical Use | Medical, food, optical | General industrial |
Clear silicone is the preferred choice when visibility, purity, or optical performance is required. Translucent silicone is suitable for general sealing applications where clarity is not a priority.

| Property | Transparent Silicone | Pigmented Silicone |
| Transparency | High | Low |
| Cure System | Platinum | Peroxide or platinum |
| Purity | Very high | Moderate–high |
| Extractables | Minimal | Varies |
| Medical/Food Use | Excellent | Application‑dependent |
| Temperature Range | –60°C to +230°C | Similar |
