Key Features
Silicone Elastomer Film is a crosslinked polydimethylsiloxane (PDMS) film combining the widest functional temperature range of any common flexible film material with established biocompatibility to USP Class VI standards:
Widest Functional Temperature Range of Any Common Flexible Film
Continuous service from −60 °C to 200 °C with short-term tolerance to higher temperatures exceeds the functional temperature range of all organic polymer film materials and qualifies silicone film for simultaneous cryogenic and high-temperature service within the same assembly.
Elastomeric Recovery Without Fatigue Failure
Tensile elongation of 100–800% and the ability to undergo repeated deformation without fatigue failure distinguish silicone film from all rigid and semi-rigid polymer films in applications requiring sustained elastic recovery, such as medical device diaphragms and sealing membranes.
Established Biocompatibility to USP Class VI
Biocompatibility to USP Class VI standards and the absence of toxic leachables qualify silicone film for direct contact with biological tissues and fluids in medical device, pharmaceutical, and food-contact applications.
Chemical Inertness of the Inorganic Si-O Backbone
The inorganic Si-O backbone gives inherent thermal stability, chemical inertness to most solvents and aqueous media, and physiological compatibility that organic polymer films cannot match. This is the fundamental material distinction that qualifies silicone for applications where organic polymer films would swell, dissolve, or leach.
Good Dielectric Properties and Low Moisture Absorption
Moisture absorption below 0.2% and good dielectric properties support electrical insulation applications in automotive and aerospace wiring across the full service temperature range, from cryogenic to 200 °C.
Industrial Applications
Silicone Elastomer Film is used across medical device, pharmaceutical, food processing, aerospace, and microfluidics applications wherever the unique combination of widest functional temperature range, elastomeric recovery, and USP Class VI biocompatibility determines material selection:
- ✦ Medical Device Gaskets and Diaphragms
- Used for medical device gaskets and diaphragms where USP Class VI biocompatibility, chemical inertness, and the −60 °C to 200 °C service range support reliable sealing performance across sterilization and storage conditions.
- ✦ Pharmaceutical Process Sealing Membranes
- Applied as pharmaceutical process sealing membranes where biocompatibility, chemical inertness to most solvents and aqueous media, and steam sterilization compatibility qualify silicone over less thermally and chemically stable elastomeric film alternatives.
- ✦ High-Temperature Release Films in Composite Manufacturing
- Used as high-temperature release films in composite manufacturing where the 200 °C continuous service temperature and elastomeric flexibility support repeated demolding without film fracture.
- ✦ Electrical Insulation in Automotive and Aerospace Wiring
- Applied as electrical insulation film in automotive and aerospace wiring where the service temperature range, good dielectric properties, and chemical inertness provide reliable insulation performance across demanding operating environments.
- ✦ Soft Lithography, Microfluidic Device Fabrication and Stretchable Electronics Research
- Widely used as the structural layer in soft lithography and microfluidic device fabrication, as a substrate for stretchable electronics and biosensor development, and for mechanical characterization studies of elastomeric films under repeated deformation cycles.
