Products Description
Singapore High Precision Graphite Gasket
Our range of flexible graphite products includes precision-engineered sheets, foils, papers, tapes, and strips. Manufactured using advanced exfoliation technology, natural graphite flakes undergo chemical intercalation and high-temperature expansion (1000°C+) to form vermicular structures with 0.003g/cm³ density. The binder-free material is precision-rolled into coils, offering:
- 99.5%+ purity
- ISO 9001:2015 certified quality
- ASTM F436 compliant performance
- Extreme chemical resistance (pH 1-14)
- Thermal stability (-200°C to +650°C)
- Compression stress relaxation <15%
Ideal for Singapore's high-precision industries, these gaskets ensure leak-free sealing in semiconductor, pharmaceutical, and aerospace applications. Composite variants with stainless steel/Inconel reinforcement available.
Custom Manufacturing Capabilities:
- CNC laser-cutting for ±0.05mm tolerance
- Die-stamped gaskets for complex geometries
- Vacuum-formed high-temperature insulation pads
