Insulation Materials

To minimize heat loss and ensure temperature uniformity within hot zone, we supply high-purity graphite insulation materials including graphite soft felt, rigid felt and graphite foil. These materials act as thermal barriers, stabilizing the temperature environment for crystal growth as well as epitaxy reactor.Also they can reduce thermal gradients that could affect deposition uniformity. Our insulation materials are available with customizable cut and thickness to meet the most demanding semiconductor process requirements.

GRAPHITEMATRIX High-Purity Graphite Insulation & Protective Materials

At Graphite Matrix, we offer a wide range of high-purity graphite insulation and protective materials for epitaxy, crystal growth, and high-temperature furnace applications. Our portfolio includes graphite felt (soft and rigid), graphite foil, and customized thermal insulation solutions, designed for **superior heat resistance, low thermal conductivity, and high purity.

1. High-Purity Graphite Foil

Graphite foil is a versatile protective material used in high-temperature applications, particularly for crucible protection and thermal radiation shielding. It is often combined with other graphite thermal insulation materials to form composite insulation structures, delivering best-in-class insulation, temperature uniformity, and process stability.

Key Features & Specifications

Ultra-high purity – Impurity level ≤20 ppm, preventing contamination.
Thermal stability – Withstands extreme temperatures in semiconductor processes.
Flexible & easy to cut – Tailored to specific application needs.

2. High-Purity Graphite Insulation Materials

To minimize heat loss and ensure temperature uniformity, we provide high-purity graphite insulation materials, including soft felt and rigid felt. These materials act as effective thermal barriers, helping maintain stable thermal environments for crystal growth and epitaxy hot zones.
