Ultra Thin Silicone Membrane
Ultra Thin Silicone Film Supplier
Ultra thin silicone membranes are precision-engineered silicone films designed for applications where a very small thickness, high flexibility, and stable mechanical response are critical.
Compared with standard silicone sheets, ultra thin membranes are supplied in film form with tightly controlled thickness, excellent elastic recovery, high dielectric strength and good permeability to gas and water vapor.
They are widely used in diaphragms, sensors, laboratory devices, vacuum laminating processes, optical covers, medical components and any situation where a thin, clean, flexible barrier is required instead of a conventional rubber sheet.
Ultra Thin Silicone Membrane
Ultra thin silicone membrane is a calendered or cast silicone elastomer produced in very small thicknesses, typically well below standard sheet ranges. It maintains the core advantages of silicone rubber:
- Wide operating temperature range
- Good elastic behavior and low compression set
- Resistance to UV, ozone and weathering
- Chemical inertness to many common media
- but in a film-like form factor that can bend, stretch and flex with minimal resistance.
In addition, ultra thin silicone membranes are:
- Highly flexible even at low temperatures
- Dimensionally stable under repeated mechanical cycling
- Permeable to gas and water vapor
- Dielectrically strong for electrical insulation and sensor protection
These combined properties make them suitable for precision diaphragms and functional films where traditional rubber sheets are too thick or too stiff.

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone sheets in roll form are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.

Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test rolls can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.

After-Arrival Support
If any damage or discrepancies are discovered during unloading or inspection, customers may contact us within 7 days with photos and batch information. Our team will respond promptly to assess the situation and provide a reasonable solution.
