Buyers researching "high cost performance thermal pads price list" are typically engineers, procurement specialists, or product designers trying to balance thermal management budgets against performance requirements. Within the electronics cooling material market, the LC Series Thermal Silicone Pad lineup from UnionTenda, LTD offers a structured answer to this exact question: a full range of thermal interface materials spanning general-purpose, cost-effective options through to high-performance pads engineered for demanding, high-power-density applications.

Understanding the LC Series Product Lineup

UnionTenda, LTD positions the LC Series as thermal interface material pads for electronics cooling, ranging from general-purpose cost-effective gap fillers to products built for high-power-density devices and applications with high heat dissipation demands. The series currently includes eleven distinct products: LC150, LC200, LC300, LC400, LC500, LC600, LC800, LC1000, LC1200, LC1500, and LC1800 Thermal Silicone/Conductive Silicone Pads.

This tiered structure is the direct answer to anyone comparing a "price list" mindset against performance: rather than a single product, buyers get a spectrum of thermal conductivity levels — from 1.5±0.15 W/m·K up to 18.0±0.5 W/m·K — allowing selection based on actual thermal load rather than over-specifying or underpaying for unnecessary capability.

Why Thermal Interface Pads Matter

The core engineering problem these pads solve is well defined. Trapped air in gaps between heat-generating components and heat sinks or machine casings reduces thermal transfer, and uneven surfaces create additional gaps that lower cooling performance. For high-power-density devices, the challenge intensifies: these components require a close thermal connection between the heat source and heat sink to reduce interface thermal resistance and improve heat dissipation efficiency. The LC Series addresses both ends of this spectrum through its graduated product tiers.

General-Purpose, Cost-Effective Tier: LC150, LC200, LC300

For users whose primary concern is cost performance rather than extreme thermal demands, the LC150, LC200, and LC300 Thermal Silicone Pads are positioned as general-purpose, cost-effective thermal interface materials with high cost performance for electronics cooling. These products target chips, processors, storage devices, base stations, routers, automotive ECU/BMS systems, and power modules.

Their differentiated value centers on cost efficiency at a cost-effective material level: LC150 delivers thermal conductivity of 1.5±0.15 W/m·K, LC200 reaches 2.0±0.2 W/m·K, and LC300 achieves 3.0±0.3 W/m·K. All three maintain dielectric strength ≥10 kV/mm and volume resistivity ≥1×10^13 Ω·cm, ensuring reliable electrical insulation during gap filling in electronics assemblies. Each also carries slight inherent tackiness, supporting multiple disassembly and reassembly cycles for easier installation and rework. Operating temperature ranges extend from -40 to 150 °C for LC150 and LC200, and -40 to 200 °C for LC300, with a V-0 flammability rating across the tier.

These pads are supplied as physical sheet pads, with LC150 and LC200 available in thicknesses from 0.3 mm to 15 mm, and LC300 from 0.5 mm to 15 mm, giving procurement teams flexibility to match exact gap-filling requirements without overpaying for unused thickness ranges.

High-Thermal-Conductivity Tier: LC400, LC500, LC600

Moving up the performance curve, LC400, LC500, and LC600 Thermal Conductive Silicone Pads are positioned as high-thermal-conductivity gap filler pads with strong thermal performance for electronics cooling. These products target scenarios where heat-generating components need a continuous thermal pathway to heat sinks or device enclosures, with air displacement and full contact required to increase heat dissipation area and cooling efficiency.

LC400 provides 4.0±0.3 W/m·K thermal conductivity with thermal impedance of 0.386 °C·in²/W at 1 mm and 10 psi; LC500 reaches 5.0±0.3 W/m·K with 0.298 °C·in²/W impedance; and LC600 achieves 6.0±0.3 W/m·K with 0.225 °C·in²/W impedance. All three retain dielectric strength ≥10 kV/mm, volume resistivity ≥1×10^13 Ω·cm, V-0 flammability, and an operating range of -40 to 200 °C. They are supplied as physical sheet pads in thicknesses from 0.5 mm to 10 mm.

High-Power-Density Tier: LC800, LC1000, LC1200, LC1500, LC1800

For applications with the highest heat dissipation demands, UnionTenda, LTD offers LC800, LC1000, LC1200, LC1500, and LC1800 Thermal Silicone/Conductive Silicone Pads. These are positioned as thermal materials designed for high-power-density devices and applications with high cooling demands, where close thermal connection between heat source and heat sink is essential to reduce interface thermal resistance.

Thermal conductivity scales progressively: LC800 at 8.0±0.5 W/m·K, LC1000 at 10.0±0.5 W/m·K, LC1200 at 12.0±0.5 W/m·K, LC1500 at 15.0±0.5 W/m·K, and LC1800 at 18.0±0.5 W/m·K. Corresponding thermal impedance drops accordingly, from 0.207 °C·in²/W for LC800 down to 0.115 °C·in²/W for LC1500 and LC1800, reflecting the tighter thermal pathway these higher-tier pads create. Dielectric strength varies by tier (≥7 kV/mm for LC800 down to ≥5 kV/mm for LC1000, then ≥6 kV/mm for LC1200 through LC1800), with volume resistivity at ≥1×10^12 Ω·cm or ≥1×10^13 Ω·cm depending on the specific product. All maintain V-0 flammability and an operating range of -40 to 150 °C, supplied as physical sheet pads in thicknesses ranging from 0.5 mm up to 10.0 mm depending on the specific product.

Shared Features Across the Series

Regardless of tier, every LC Series pad shares four consistent characteristics that support the "high cost performance" value proposition buyers are searching for: low cost and high cost performance through cost-effective material formulation that lowers thermal management material cost while meeting cooling requirements; natural stickiness from slight inherent tackiness that simplifies installation and supports rework across multiple disassembly and reassembly cycles; softness and compressibility that allows the conformable material to fill uneven gaps of different sizes, displacing air and maintaining full thermal contact; and weather resistance and aging resistance that keeps properties stable over time for long-term reliable use.

Industry Applications

Across the series, UnionTenda, LTD's LC Series pads serve electronics applications involving chips, processors, and storage devices paired with heat sinks or casings, improving component cooling and device reliability. In communications, base stations, routers, and communication equipment benefit from long-term stable cooling under sustained operation. Automotive applications include electronic control units and battery management systems requiring thermal interfaces within operational temperature limits, while power electronics applications rely on these pads for thermal management between power modules and heat sinks to lower operating temperatures.

Choosing the Right Tier for Your Budget and Performance Needs

For buyers comparing a thermal pad price list against performance specifications, the LC Series structure from UnionTenda, LTD offers a clear decision framework: select LC150 through LC300 for general-purpose, budget-conscious cooling needs; move to LC400 through LC600 when higher thermal conductivity and lower thermal impedance are required; and choose LC800 through LC1800 for high-power-density devices demanding the tightest possible thermal connection. This tiered approach allows procurement and engineering teams to match thermal conductivity, dielectric properties, operating temperature range, and thickness options precisely to application requirements, rather than defaulting to a single one-size-fits-all product.
