High-performance PEI Sheet (Polyetherimide Sheet) has become a core structural material for semiconductor manufacturing protection systems. AHD’s 5-80mm thick amber PEI sheet features low outgassing, high temperature resistance and stable dimensional performance, fully complying the industry standards. This unfilled virgin PEI sheet is widely adopted for semiconductor device protective covers, wafer handling shields and lithography equipment barriers, delivering reliable shielding and anti-contamination performance for precision chip production.
Core Properties of 5-80mm Unfilled Virgin PEI Amber Sheet
Our unfilled virgin amber PEI Plastic Sheet 5mm to 80mm is made of pure PEI raw materials without any additions of fillers, thus offering ultra-high purity which is suitable for strict semiconductor production environments. The material is an amber thick plate of high temperature resistant PEI for long-term use in high-temperature semiconductor processing workshops, with a glass transition temperature of 217°C and a heat deflection temperature of up to 190°C.
This Low outgassing grade PEI amber sheet is also environmentally adaptive as it does not emit a significant amount of volatile organic compounds while operating at elevated temperatures to prevent wafer surface contamination and damage to precision components. In the meantime, its high dimensional stability thick PEI amber board has outstanding performance, with thermal expansion coefficient of 5.5×10-5/°C, resisting deformation under frequent temperature change and mechanical vibration in fab workshops.
In addition, the transparent amber PEI Sheet (Ultem 1000 sheet) has uniform amber transparency so that technicians can see the internal equipment operation status without removing the protective covers. It is inherently flame retardant (UL94 V-0) and compliant with RoHS and REACH environmental regulations, ideal for the closed and high-precision semiconductor manufacturing environments.
PEI Sheet, also knows as Ultem PEI Sheet
Semiconductor-Grade Chemical & Mechanical Advantages
Semiconductor manufacturing involves various corrosive chemicals such as photoresist, cleaning agents and etching solutions, which puts forward strict anti-corrosion requirements for protective materials. Our Chemical resistant amber PEI sheet semiconductor grade shows outstanding tolerance to most organic solvents, weak acids and alkalis. It will not swell, crack or degrade after long-term contact with semiconductor processing chemicals, greatly extending the service life of protective equipment.
Mechanically, the thick PEI amber plate maintains stable tensile strength of 85MPa and flexural modulus of 3200MPa. Unlike ordinary plastic sheets that are prone to brittle fracture, this virgin PEI sheet delivers balanced toughness and rigidity. It can resist minor impact and friction during equipment operation, effectively protecting precision chips, wafers and testing components from physical damage.
Compared with ordinary acrylic and Clear PVC sheets used in traditional equipment protection, PEI sheet avoids aging, yellowing and performance attenuation in high-temperature and high-cleanliness environments. Its comprehensive performance is far superior to conventional engineering plastics, making it the preferred material for high-end semiconductor fab protection systems.
Typical Application Scenarios of Semiconductor PEI Sheet
As a professional PEI amber sheet for semiconductor device protective covers, AHD’s thick PEI board covers the whole process of semiconductor production, testing and packaging. In wafer production workshops, Thick PEI amber plate for wafer handling shield isolates wafers from external dust, static electricity and mechanical interference during transmission and storage, ensuring wafer surface cleanliness and yield rate.
In precision processing links, Semiconductor fab equipment protective cover PEI sheet is applied to lithography, etching and deposition equipment shells and baffles. Its low outgassing feature prevents gas residue from polluting precision processing chambers. For chip testing procedures, Amber PEI sheet for chip test fixture housing provides stable insulating and shielding protection for test fixtures, ensuring accurate test data and stable equipment operation.
In post-stage packaging processes, our PEI thick board for semiconductor processing shielding and Semiconductor packaging equipment PEI shielding sheet effectively isolate external electromagnetic interference and dust pollution. Besides, customized Wafer cassette protective cover amber PEI sheet and Lithography equipment PEI amber protective plate can be processed according to equipment dimensions, perfectly matching diverse production line layout requirements.
PEI vs PEEK Sheet for Semiconductor Protective Covers
The PEEK sheet has excellent extreme temperature resistance (long-term operation of 260°C) and excellent wear resistance, and is suitable for the hidden structural parts, wafer transmission components and non-visual shielding structures that require long-term friction resistance. However, pure PEEK is opaque and has no light transmission ability, which is not conducive to the real-time observation of the internal equipment. Compared with that, PEI Sheet adopts transparent amber virgin formula, which still has stable light transmittance, meanwhile, it retains 190°C long-term heat resistance and SEMI-grade low outgassing performance.
Opaque PEEK is popular for hidden wear resistant functional parts in practical semiconductor production. Amber PEI sheet is the only material used for visible protective covers, test fixture housings and lithography equipment shielding plates for visual inspection, and is available in 5-80mm thickness. This amber PEI sheet has a balanced performance and more competitive cost, which is perfectly suitable for the daily operation and maintenance needs of semiconductor equipment, and has become the preferred transparent shielding material for medium and high-end semiconductor production lines.
