Conductive Silicone Products,
EMI Shielding and Sealing in One Material

YUTIAN conductive silicone elastomers combine EMI shielding with environmental sealing — four filler systems, volume resistivity from 0.002 to 10 Ω·cm, and extruded or molded forms from solid conductive profiles to dual-layer constructions with an insulating skin.

Product Overview

One Profile, Two Jobs: Shield and Seal

RF and power electronics need both EMI shielding and environmental sealing — traditionally two parts, two assembly steps. YUTIAN conductive silicone systems solve this in one profile: a conductive filler network carries shielding, and formulations are tuned to your frequency range and sealing environment.

Filler SystemsAg / Ag-Al / Ni-C / C — four systems matched to conductivity and cost targets
ConstructionsSolid conductive, conductive-over-foam, dual-extrusion with insulating layer
ConfirmationParameters confirmed per drawing before quoting

Over 80 conductive part numbers produced over the past decade, serving telecom, power and precision-instrument OEMs.

Technical FAQ

Questions Engineers Ask First

How do I choose between the four filler systems?
It depends on your shielding requirement, galvanic-compatibility environment and cost target: silver systems give the highest conductivity, nickel-graphite offers a strong balance, carbon suits ESD applications. Share your frequency range and enclosure materials, and we will propose the system and confirm parameters per drawing before quoting.
Can you verify shielding effectiveness on my frequency band?
We specify materials against your stated shielding target and confirm parameters at specification stage. For project-specific verification, discuss the test scope with our team during quoting.
Can you make custom / non-standard profiles? Is tooling required?
Yes. Most extruded profiles (D-shape, O-shape, solid, hollow, custom sections) can be produced with our existing dies. Non-standard cross-sections require a new die; tooling cost and lead time are quoted individually based on your drawing and volume — there is no flat fee.
Can you cut to length? Do you offer bonding?
Yes, we cut to your required length; special cutting and splicing/bonding are available. Whether cutting is charged depends on the process and quantity.
What colors are available?
Standard colors include black, white, transparent, red, blue and grey. We can color-match to a RAL number or your sample. Special colors may affect price — quoted per order.
What is the MOQ? Do you sell short lengths?
Free samples are available for stock products. After sample approval, order MOQ is typically 500–1,000 meters depending on the product (confirmed in the quote). For the sample stage, even a few meters can be arranged.
Are samples free? How fast can you provide them?
Stock samples are free of charge; shipping is paid by the customer. Custom sample tooling is evaluated by process. Sampling typically takes 3–7 days.
