7. Frequently Asked Questions (FAQ)
Q1: How is the conductivity of this silicone rubber tubing achieved?
A: Conductivity is imparted by dispersing fine conductive particles (e.g., carbon black, nickel-coated graphite) uniformly throughout the silicone rubber matrix during compounding. The concentration and type of filler determine the final volume resistivity.
Q2: Can the tubing be cut and installed easily?
A: Yes. Our conductive silicone rubber tubing can be easily cut to length with sharp blades or scissors. Its flexibility allows it to be slipped over wires, cables, or components effortlessly. For a permanent seal, compatible silicone adhesives can be used.
Q3: How does it compare to metal braid for EMI shielding?
A: While metal braid offers excellent shielding, it is heavier, prone to corrosion, and can be abrasive. Our tubing provides very good shielding effectiveness (often >30 dB across key frequencies) with added benefits of sealing, flexibility, corrosion resistance, and weight savings, making it ideal for dynamic or sealed applications.
Q4: Is it suitable for outdoor or high-UV environments?
A: Absolutely. Silicone rubber inherently possesses excellent resistance to ozone, UV radiation, and weathering. Our conductive silicone rubber tubing is formulated to maintain its electrical and mechanical properties when exposed to sunlight and outdoor elements for extended periods.
Q5: Do you offer custom formulations or sizes?
A: Yes, customization is a core part of our service. We can adjust the compound for specific resistivity, temperature range, color, or flame retardancy (UL94 V-0). We also manufacture custom inner diameters, wall thicknesses, and can provide cut lengths or spooled packaging.
