Industry News: Exploding Demand for Vacuum & Cleanroom Equipment Makes Low-Outgassing peek/PI Non-Metallic Fasteners a Semiconductor Industry Must-Have
Semiconductor, optoelectronic and precision optical equipment require micro and nano-level cleanliness in production environments. Traditional metal screws produce fine dust and metal debris, while ordinary nylon plastics release volatile substances and oil precipitation under vacuum and high temperature, contaminating chambers and precision components. Therefore, low-outgassing, low-volatility, dust-free, non-magnetic and high-temperature resistant peek and PI polyimide fasteners have become essential standard parts for high-end vacuum and cleanroom equipment.
Performance Gap Between Ordinary and High-End Polymers
Ordinary pa66/PPS: Cost-effective and versatile, but prone to small-molecule precipitation and frosting under vacuum & high temperature, causing lens fogging and chamber contamination, not applicable for core semiconductor processes.
PEEK polymer: Ultra-low outgassing and volatility, low water absorption and excellent dimensional stability, suitable for long-term operation of mid-to-high-end vacuum and optical equipment.
PI polyimide: Top-tier low-volatility material with ultra-high temperature resistance and zero impurity precipitation, widely used in high-precision vacuum chambers, wafer equipment and ultra-high-purity laboratory environments.
Core Semiconductor Procurement Standards
- Low-VOC, low-outgassing, silicon-free and halogen-free formula to avoid precision circuit and optical lens contamination;
- Dust-free production and packaging to prevent particle falling during operation;
- Non-magnetic property to avoid interference with electromagnetic and optical detection accuracy;
- High batch consistency with available outgassing and material purity test reports.
Common Procurement Misjudgment
Many purchasers generally select “plastic screws” and replace PEEK/PI with ordinary nylon or PPS, resulting in chamber contamination, reduced product yield and failed overseas factory audits. Semiconductor equipment is high-precision asset; tiny fastener precipitation may cause irreversible loss, making material downgrade extremely risky.
Market Trend
With accelerated localization of domestic semiconductor equipment, shipments of high-end cleanroom and vacuum equipment keep rising, continuously expanding the low-outgassing specialty non-metallic fastener market. Procurement focus shifts from cost-saving to yield stability, compliance and quality consistency. High-purity PEEK, PI and ceramic fasteners will maintain long-term growth.
