CULD™ ePTFE
CULD™ ePTFE is a chemically inert, non-contaminating polymer engineered for extreme environments. It combines exceptional thermal, chemical, and electrical performance with industry-leading cleanroom compatibility.
• Thermal stability from cryogenic to 500 °F (260 °C) continuous use.
• Exceptional resistance to chemicals, UV, hydrolysis, and microbiological attack.
• Non-flammable, low-friction, non-stick surface ideal for cleanroom sealing.
• High dielectric strength and long-term durability under harsh conditions.
Standards Compliance
ASTM E595 – Vacuum Outgassing (Low VOC Release)
ASTM E2312 – Cleanroom Material Evaluation (VOC, NVR, particulates)
Proven compatibility with ASTM E595 and ASTM E2312 makes CULD™ ePTFE an ideal choice for semiconductor, pharmaceutical, and aerospace applications requiring unmatched purity and reliability.
ThreeSquared™ CULD™ Gasket Solutions
CULD™ (Cleanrooms Ultra Low Density) is a patented ePTFE gasket technology engineered by ThreeSquared Solutions to dramatically reduce Airborne Molecular Contamination (AMC).
• Ultra-low outgassing for critical cleanroom sealing.
• Proven in top-tier semiconductor fabs and life science facilities.
• Outperforms traditional gasket materials in purity and stability.
• Trusted by leading manufacturers and repeat clients.
Standards Compliance
ASTM E595 – Vacuum Outgassing (Low VOC Release)
ASTM E2312 – Cleanroom Material Evaluation (VOC, NVR, particulates)
ThreeSquared™ delivers exclusive sealing technologies including CULD™ and advanced gel gaskets, backed by proven ASTM E595 and E2312 compatibility. These solutions set a new standard in cleanroom integrity, contamination control, and installation reliability.
Drop-In-Seal-Kit™ (D-I-S-K™)
ThreeSquared Solutions™ for cleanroom ceiling grids and bottom load filters. It enables rapid, clean, and consistent replacement of defective gels, eliminating the messy and costly re-pour process.
• Factory-cured gel strip with multi-year shelf life, produced in a cleanroom.
• Drop-in installation minimizes downtime and avoids gel re-pouring.
• Underside gel seals the grid structure; topside gel accepts filter knife-edges.
• Performs on unlevel ceiling grids without laser leveling.
• Easily removable gel strip for simplified remediation and safety.
• Successfully tested by ChemTrace Labs for low off-gassing to Intel specifications (50 °C / 30 min).
