Silicone Extrusion

One-stop solution for Custom Silicone Extrusion!

Custom Silicone Extrusion

Silicone extrusion is a process that uses a die to where silicone materials are forced to form a shape. Cross-sections, complex profiles, and continuous lengths are formed. The extrusion process is ideal for silicone because of its elastic properties. We offer silicone extrusion in different profiles such as custom profiles, H profiles, D profiles, wedge profiles, L profiles, and more. Through extrusion, we are able to produce different products such as finned tubes, gaskets, sponges, and more.

Silicone Material Properties

Silicones, also known as polysiloxanes, are plastic polymers composed of oxygen atoms and silicon. Owing to their rubber-like characteristics, they are frequently referred to as synthetic rubber. Silicones can be produced into a wide range of products due to their malleability, heat resistance, gas permeability, and flexibility. Using a silicone extrusion process, the finished product can be extruded in continuous lengths or cut to size and packaged to exceed the needs of the customer.

Silicone rubber extrusions are extremely useful methods for various industries such as medical, automotive, and industrial. It is an affordable process that provides short lead times even producing a large volume of products. Silicone extrusion products can last longer, come in more colors, and withstand a wider range of environmental conditions.

Wide Materials for Silicone Extrusions

LegenDay produces solid silicone elastomer extrusions in diameters up to 2.500″ and countless shapes and hardnesses. We work with various silicone extruded materials such as 6309, 6304-NSF, 6404-NSF, 6409, 6504-NSF, 6604, 6609, and more. Extruded profiles, tubes, and cords are utilized to make O-rings, seals, grips, handles, and gaskets. These products guarantee worker safety and operations. Rubber extrusions with a larger diameter are frequently used as bumpers and guards to protect machinery.

We provide commercial-grade silicones that are maintenance-free in less-demanding environments. Our materials can withstand 500,000 flexes, FDA compliance made with FDA ingredients. They exhibit excellent resistance to temperature extremes and compression sets.

Can Silicone Be Extruded?

The process of forcing silicone through a shaped die to form a continuous length of material with intricate cross-sections and profiles is known as silicone extrusion. Since silicone is a durable synthetic rubber, its elastic qualities make it the perfect substance to use in the extrusion method.

How Long Does Silicone Extrusion Product Last?

Silicone rubbers typically retain their primary performance characteristics for 6 months on average when maintained properly, and up to 12 months in some circumstances.

Can Silicone Be Affected By the Environment?

Silicone material is resistance to various extreme conditions including wet, cold, hot, dry and humid environmental conditions. Plus, it is immune to UV and ozone deterioration.

What are the Silicone Extruded Products Advantages?

There are numerous beneficial qualities of silicone rubber, including:

  • Stable and unreactive
  • Able to offer efficient thermal insulation
  • Can stabilize joins and lessen vibration
  • It is simple to pigment into a range of colors
  • More resistant to extreme high and low temperatures
  • Keeps its flexibility across a broad temperature range.
  • Ozone and UV resistant
Is Silicone Poisonous?

Silicone is a BPA-free material, with almost no toxic effects in most environments. It is a safe polymer material suitable choice for a broad range of food and beverages application. Silicone can be disposed of in accordance with regional waste disposal laws because it is not regarded as hazardous waste.

What is the Temperature Range for Products Made of Silicone?

Silicones have a -50°C to +200°C temperature range. High-temperature grades of silicone are available with operating temperatures up to 300°C. Low-temperature grades are also available, with operating temperatures as low as -110°C.

How Many Silicone Extrusion Profile are There?
