How Do You Choose a Silicone Sheet Manufacturer?

Given the number of accessible silicone manufacturers, it may be challenging to identify the appropriate one to collaborate with. However, there are several factors that you should consider when searching for a manufacturer to assist with the development and manufacturing of your products.

The very first step is to assess the needs of your company or business to give you a clearer picture of the services you want. Being upfront and as specific as possible about your quality, speed, and communication expectations might help you select a manufacturer that meets your requirements.

Here are some considerations to make before selecting a silicone manufacturing partner:

Expertise

A reputable silicone manufacturer with a track record of creating high-quality products, parts, and components generally possesses substantial knowledge and expertise. This can be a real advantage for your company or business.

Expertise in construction management and trained personnel also contribute to producing silicone goods of the highest quality.

Location

When selecting a manufacturer for your silicone products, deciding whether to go with a domestic or foreign company is essential. As with any selection, both alternatives have advantages and downsides, but it is vital to evaluate the long-term consequences.

Communication

Communication is essential to the manufacturing process of a product, whether at the initial contact with the manufacturer, during the design phase, or after the product has been manufactured. Therefore, choosing a company that is easy to communicate with is important.

Moreover, selecting a manufacturer within or close to the same time zone might eliminate communication obstacles, particularly in the case of urgent requirements.

History

It is generally a good practice to engage with a silicone manufacturer with a reputation for providing satisfactory results. Selecting a manufacturer who caters specifically to your vertical can prevent you from making potentially expensive errors. Consider asking manufacturers what types of projects they have accomplished and evaluate how your project would fit into their past work.

Properties of Solid Silicone Sheet

Solid silicone sheets are known for their excellent thermal properties, including a wide operating temperature range and good thermal resistance, and their superior weather and ozone resistance. They are also resilient, chemically stable, flexible, and exhibit low toxicity and good electrical insulation. While resistant to many things, they are not resistant to oils, concentrated acids, or certain solvents.

  • Temperature resistance: They perform well over a wide temperature range, maintaining flexibility at both high and low temperatures. 
  • Chemical resistance: Silicone sheets are resistant to ozone, UV radiation, oxygen, and water. They are also chemically inert and non-toxic. However, they are susceptible to attack from oils, solvents, concentrated acids, and dilute sodium hydroxide. 
  • Physical properties: They are resilient, flexible, and elastic, with good tensile strength and tear resistance. They are also known for being tasteless and odorless, making them suitable for food-grade applications. 
  • Electrical properties: They have excellent electrical insulation properties, though some specialized grades can be made electrically conductive. 
  • Weather and environmental resistance: They exhibit excellent resistance to weathering and can repel water to form watertight seals. 
  • Biocompatibility: Silicone is non-toxic and has high biocompatibility, making it suitable for medical and clean industry applications. 

Silicone Matting and Silicone Mats

Silicone matting (silicone mats) are flexible, non-stick sheet materials that are often make of food-grade silicone. Silicone mats are reusable and can withstand a wide range of temperatures. This makes them a durable alternative to parchment paper or aluminum foil for food service and food processing applications. Some silicone mats are “mesh mats” with perforations to improve airflow and reduce spreading, while others are solid sheets. ElastaPro can provide you with silicone matting and offers low minimum order quantities (MOQs).

Silicone Rolls vs. Silicone Sheets

The main difference between silicone rolls and silicone sheets is that silicone rolls are long, continuous sheets of material that can be cut to any length, while silicone sheets are calendered or compression molded to a specific size (e.g., 12″ x 12″). Often, silicone rolls are used for custom parts and large applications. Silicone sheets can be pre-cut and are often provided for specific applications. ElastaPro can provide you both silicone rolls and silicone sheets.
Feature Silicone Rolls Silicone Sheets
Form Continuous, long sheets available in various widths and thicknesses, similar to a bolt of fabric. Can refer to the same long rolls, or pre-cut, specific-sized pieces.
Application Typically used for custom parts, large-scale industrial applications, and when a length needs to be cut to size. Used for custom applications when cut from a roll, or for specific purposes like medical scar treatment, sealing, or in robotics and printing applications.
Processing Often produced by calendering or rotocuring, resulting in tight thickness tolerances. Can be manufactured similarly to rolls or may be molded into specific shapes.
Customization Provides flexibility to cut to the exact size needed for a particular project. Pre-cut sheets are ideal for specific uses, while rolls offer more flexibility for customization.

Thin Silicone Sheet

Thin silicone sheet is a high-performance elastomeric material used across industries that demand flexibility, temperature resistance, and durability in compact or precision assemblies. Engineers choose thin silicone sheets when space is limited, sealing tolerances are tight, or lightweight performance is required. These sheets combine the mechanical stability of silicone with the adaptability of thin-gauge materials.

Material Properties

Silicone rubber is a synthetic elastomer derived from polysiloxane, a polymer chain featuring alternating silicon and oxygen atoms. This structure gives silicone its unique combination of thermal stability, chemical resistance, and elasticity. Thin silicone sheet retains these base characteristics but in a format designed for precision.

Key properties include:

  • Temperature resistance: Continuous operation from -60°C to +230°C, with some formulations tolerating even higher peaks.

  • Flexibility and resilience: Excellent elongation and compression set performance, allowing for reliable sealing in dynamic or vibrating assemblies.

  • Chemical and UV stability: Resistance to ozone, oxidation, and most environmental agents, ensuring long-term durability.

  • Dielectric strength: Electrical insulation values exceeding 500 V/mil, making it suitable for electronic and EMI/RFI gasket applications.

  • Biocompatibility (optional): Medical and food-grade thin silicones meet FDA, USP Class VI, and ISO 10993 standards for sensitive environments.

Manufacturing and Variants

Thin silicone sheets are produced through calendering, extrusion, or molding processes, depending on the required precision and performance. Calendering yields consistent thickness and smooth surface finish, which is essential for sealing films and membranes. Liquid silicone rubber (LSR) can also be cast into ultra-thin layers with excellent uniformity for optical, electronic, and biomedical uses.

Engineers can select from several material variants:

  • Solid silicone sheet: Offers mechanical strength and dimensional stability.

  • Sponge silicone sheet and foam silicone sheet: Provide compressibility and conformability where surface irregularities must be sealed.

  • Fluorosilicone sheet: Adds resistance to fuels, oils, and solvents for aerospace and automotive environments.

Applications in Engineering Design

Thin silicone sheet is used wherever a durable, flexible, and stable interface is required. Typical applications include:

  • Gaskets and seals: For small enclosures, sensors, and electronics where space and weight savings are critical.

  • Thermal insulation and vibration damping: In electronic assemblies or power systems exposed to heat and mechanical stress.

  • Protective membranes and diaphragms: In fluid control devices, medical pumps, and pressure sensors.

  • Electrical insulation: In high-voltage or sensitive circuitry environments.

  • EMI/RFI shielding layers: When combined with conductive fillers or coatings to prevent electromagnetic interference.

Advantages for Engineers

Thin silicone sheet offers several design advantages. It can be die-cut, laser-cut, or waterjet-cut with tight tolerances, allowing engineers to produce precise gaskets, washers, or films. The material maintains elasticity and performance even at extreme temperatures, reducing maintenance needs. Moreover, thin silicone’s low compression set and long service life contribute to overall system reliability.

From compact electronics to aerospace systems and medical devices, thin silicone sheet represents an ideal combination of performance, precision, and versatility.
