TIS300 — Product overview
TIS®300 Series is a nickel/graphite-filled conductive silicone sheet is developed for thermal management and electromagnetic interference (EMI) suppression in 3C electronic products, high-frequency signal equipment and precision electromagnetic components. It delivers excellent thermal conductivity and surface resistivity, together with high compressibility and soft elasticity, making it suitable for low-pressure mounting conditions. This material series resists galvanic corrosion and maintains its stability under harsh environmental conditions
TIS®300 Electrically Conductive Silicone — what to validate in production

TIS®300 Electrically Conductive Silicone — common questions
Replacing another vendor's TIM or need a stack review? Send drawings — applications responds quickly.
Talk to an engineerWhat is the nominal thermal conductivity of TIS300?
The customer workbook lists nominal through-plane conductivity as 4.5 W/m·K. What you measure depends on pressure, gap, and fixture — use the technical documentation as the reference.
Can Ziitek supply TIS300 die-cut or in custom thickness?
Yes — send DXF/DWG outlines and stack height. Thermally conductive insulators parts are routinely converted at Ziitek; tolerances depend on thickness and geometry.
Where is the documentation for TIS300?
Download the technical documentation from this page when available. If your revision differs, name the file from your RFQ so applications engineering matches it.
Is TIS300 RoHS-aligned?
Ziitek targets RoHS-oriented formulations across TIM lines. Cite the compliance block for audits and tell us if you need additional regional substance lists.
