How to choose the right rubber material for my extrusion application?

Choosing the right rubber really comes down to how the part will be used. Things like the environment, any chemicals around it, and how much stress it will take all affect the best material choice. Knowing these factors helps avoid problems and makes the product last longer. When you work with the team at RUBBER SILICONE MOLDS, you get expert help picking the right material for every project.

• Temperature range: Extreme heat would not be able to impact much on silicone or FKM; outdoor applications involving heat and steam are safe with EPDM.
• Chemical exposure: Oils need Nitrile; extremely harsh chemicals will need FKM.
• Mechanical needs: Several aspects, like durometer, flexibility, and compression set, affect performance.
• Regulation Standard: Medical and food applications require certified materials.
• Budget: Advanced materials may be slightly more expensive but provide far better durability.

A careful review of each factor leads to a dependable and efficient final product.

What type of rubber is best for outdoor and weather-resistant seals?

Outdoor parts must resist UV rays, ozone, moisture, and temperature variations. Hence, EPDM is one of the top materials for long-term outdoor sealing because it remains flexible and does not crack or degrade over time.

Best choices for outdoor use are:

• EPDM: Industry standard for UV, ozone, and weather resistance.
• Neoprene: A good choice for applications that need some oil resistance.
• Silicone: It is the best for high temperatures or areas with constant sunlight.

These rubbers are often used to make things like window seals, door gaskets, HVAC units, roofing parts, and electrical enclosures.

What are FDA-approved rubber materials for Food and Medical Applications?

Medical Applications? Food and medical environments are required not only to be high on safety standards but also to be high on hygiene standards. FDA-approved compounds are engineered to avoid any contamination and to be able to sustain cleaning or sterilization.

Some common FDA-approved options are:

• Silicone rubber: Most widely accepted; ideal for medical tubing, gaskets, and food contact parts.
• EPDM (FDA grade): Used for water, steam, and sanitary equipment.
• Nitrile (FDA grade): Used when food machinery has contact with oil or grease.
