About Silicon Rubber Extrusions

Silicone rubber extrusions are objects made from silicone rubber that are created by forcing the silicone material through a die or extrusion machine to create a continuous profile or shape. The process involves melting and shaping silicone material into a specific cross-sectional shape or profile that can be used for various applications.Silicone rubber extrusions are commonly used in a variety of industries including medical, automotive, construction, and industrial manufacturing. They are often chosen for their flexibility, durability, and ability to withstand high temperatures, as well as their resistance to chemicals and other harsh conditions.

Some common examples of silicone rubber extrusions include:

Tubing and hoses for transporting fluids in medical and industrial applications.
Gaskets and seals used in automotive and industrial applications to provide an airtight and watertight seal.
Edge trim and bumpers for vehicles and machinery to protect against impact damage.
Profiles and channels used in construction and industrial applications to provide insulation or support.
Overall, silicone rubber extrusions are a versatile and durable solution for a wide range of applications, providing a reliable and long-lasting solution for many essential products and equipment.

Exceptional Electrical Insulation

With a dielectric strength reaching up to 20 kV/mm, silicon rubber extrusions provide reliable electrical insulation for various applications. Their low water absorption and stable thermal conductivity ensure consistent performance, even in high-voltage environments, making them suitable for automotive, industrial, and electrical sectors.

Versatile Shapes and Customization

Silicon rubber extrusions are available in a range of profiles such as D, P, E, U, Square, and can be custom-designed to meet specific dimensional needs. Widths from 3 mm to 75 mm, thicknesses from 0.5 mm to 25 mm, and multiple color optionsincluding transparentallow for tailored solutions for sealing, gasketing, and weatherproofing projects.

Superior Resistance and Longevity

Engineered to withstand harsh conditions, these extrusions offer excellent resistance to extreme temperatures (60C to +220C, intermittent up to +250C), chemicals, moisture, UV rays, and ozone. Their self-extinguishing nature (UL 94-V0) and non-toxic composition guarantee safety and durability for long-term use in demanding environments.

FAQs of Silicon Rubber Extrusions:

Q: How are silicon rubber extrusions manufactured?

A: Silicon rubber extrusions are produced through an extrusion process where 100% silicone rubber is shaped into profiles, tubes, and gaskets. This method allows for precise customization in dimensions, surface finish, and adhesion properties, catering to your specific application requirements.

Q: What applications benefit most from using silicon rubber extrusions?

A: These extrusions are widely employed in sealing, gasketing, insulating, and weatherproofing across industrial, automotive, and electrical sectors. Their robust resistance to UV, ozone, chemicals, and fluctuating temperatures ensures reliable performance in demanding environments.

Q: When should I opt for custom shapes or sizes for my extrusion project?

A: Custom shapes and sizes are ideal when standard profiles dont meet your installation needs. If your application requires unique dimensions, compression ratios, or specialized profiles, customization ensures a precise fit and optimal sealing efficiency.

Q: Where can silicon rubber extrusions be used for electrical insulation?

A: Silicon rubber extrusions with excellent dielectric strength are utilized in cable management, electrical panels, enclosures, and insulative barriers in high-voltage equipment. Their performance up to 20 kV/mm makes them suitable wherever electrical safety is paramount.

Q: What are the benefits of choosing FDA grade silicon rubber extrusions?

A: Selecting FDA grade extrusions ensures the product complies with strict safety and hygiene standards, making it suitable for food, beverage, pharmaceutical, and medical applications where non-toxic and odorless qualities are required.

Q: Can these extrusions be supplied with adhesive backing, and why is it advantageous?

A: Yes, silicon rubber extrusions can be supplied with adhesive backing, which simplifies installation and enhances adhesion to various surfaces, especially in sealing and gasketing roles where a secure, reliable bond is necessary.
