Cordierite(LOTEC™-M)
- Excellent Thermal Shock Resistance
- High Purity Material
- Low Thermal Conductivity
- Low Thermal Expansion
- Support for Complex Shapes
LOTEC™-M is a material with excellent low thermal expansion and thermal shock resistance. Our company manufactures high-purity cordierite using its proprietary electrofusion technology and has established an integrated production from raw material powder to processing. Our specialized slurry forming technology enables us to achieve complex shapes at reasonable cost and small batch prototypes. Our high performance and stable quality satisfy the needs of a wide range of industries.
Features
01. Preferred material for low thermal expansion and thermal shock resistance
Due to its high thermal shock resistance and properties of suppressing thermal expansion, cordierite is an ideal ceramic material for precision equipment and components in high-temperature environments.
02. High quality achieved through proprietary technology
High purity achieved through electrofusion technology, and an integrated production system from cordierite raw material manufacturing to processing has been established. We provide reliable products with stable quality.
03. Cost-effective production of complex shapes and prototyping in small batches
Using specialized slurry forming technology, we can achieve complex shapes at reasonable cost and small lot prototypes. We support customers’ product development smoothly.
