5. FAQ

Q: What is Carbon Fiber material ?

A: Carbon fiber material is not a single substance but a Composite Material. This means it's created by combining two distinct materials to make something superior to either one alone.

• The Fiber: The "carbon fiber" itself is the reinforcement, providing the incredible strength and stiffness.
• The Matrix: A polymer resin (like epoxy) is the glue that binds the fibers together, transfers load between them, and gives the part its shape.

Think of it like reinforced concrete:

• Carbon fibers are the steel rebar (providing strength).
• The resin is the concrete (holding it all together and providing form).

Q: What is the difference of silicon o-ring and rubber o-ring?

A:

1. Temperature Resistance

• Silicone O-rings:Excellent high-temperature resistance (-60°C to 230°C / -76°F to 446°F).Performs well in extreme heat but can degrade at very high temps (>250°C) without proper reinforcement.
• Rubber O-rings:Nitrile (NBR): -40°C to 120°C (-40°F to 248°F).
• EPDM: -50°C to 150°C (-58°F to 302°F).
• FKM (Viton): -20°C to 200°C (-4°F to 392°F).

Winner: Silicone for extreme high & low temps.

2. Chemical Resistance

• Silicone O-rings:Good resistance to water, ozone, and UV light.Poor resistance to fuels, oils, acids, and solvents.
• Rubber O-rings:Nitrile (NBR): Excellent resistance to oils & fuels.
• EPDM: Resistant to water, steam, and mild chemicals.
• FKM (Viton): Excellent resistance to fuels, oils, acids, and harsh chemicals.

Winner: Rubber (NBR/FKM) for oil & chemical resistance.
