Clear Silicone Sheet

Clear silicone sheet is a high‑purity, platinum‑cured elastomer engineered for applications that require transparency, cleanliness, and long‑term performance. These transparent silicone sheets provide excellent visual clarity, making them ideal for environments where operators must inspect fluid paths, gasket alignment, or component interfaces. ElastaPro manufactures clear silicone sheets in a wide range of thicknesses, durometers, and formats—including continuous rolls—to support both prototyping and high‑volume converting.

What Is a Clear Silicone Sheet?

A clear silicone sheet is a flexible, optically transparent silicone material produced using a platinum‑cure (addition‑cure) system. This curing method minimizes extractables, eliminates peroxide by‑products, and delivers exceptional clarity compared to standard translucent silicone. Clear silicone sheets maintain their transparency over time, resisting yellowing, haze, and environmental degradation.

Benefits of Clear Silicone Sheets

  • High optical clarity for visual inspection and light transmission
  • Platinum‑cured purity with extremely low extractables and volatiles
  • Excellent temperature resistance from –60°C to +230°C
  • Non‑yellowing stability under UV, ozone, and environmental exposure
  • Available in FDA‑grade and USP Class VI options
  • Flexible, durable, and tear‑resistant for demanding applications
  • Compatible with autoclave, gamma, and EtO sterilization

  • High‑purity gasketing and diaphragm components

Clear Silicone vs. Translucent Silicone

Property Clear 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.

Cure System Platinum Peroxide or platinum
Purity Very high Moderate–high
Extractables Minimal Varies
Medical/Food Use Excellent Application‑dependent

FAQ: Clear Silicone Sheets

Is clear silicone sheet food‑grade?

Platinum‑cured clear silicone can be formulated to meet FDA 21 CFR 177.2600 requirements for repeated food contact.

Does clear silicone yellow over time?

High‑purity platinum‑cured silicone resists yellowing and maintains clarity even under UV and ozone exposure.

Is clear silicone safe for medical applications?

Clear silicone formulations can be formulated to meet USP Class VI and ISO 10993 biocompatibility requirements.

Can clear silicone sheets withstand high temperatures?

Clear silicone maintains flexibility and mechanical stability from –60°C to +230°C, making it suitable for both hot and cold environments.

Do clear silicone sheets come in continuous rolls?

Yes. ElastaPro supplies clear silicone in both sheets and continuous rolls for converters and OEMs.
