ATOMFAIR® WET-PROCESS PE SEPARATOR 7UM

RESEARCH GRADE MATERIAL

Product Overview

Premium ultra-thin wet-process Polyethylene (PE) separator explicitly optimized for cutting-edge battery R&D and laboratory-scale assemblies. This ultra-thin micro-porous matrix provides highly reliable electrode isolation to completely prevent internal physical shorting, while its uniform channel framework ensures rapid, unhindered ion transport. Formatted at a precise 60mm × 10m sizing matrix, it delivers a highly consistent baseline verification control for high-power density cells, solid-state configurations, and refined academic electrochemical validation routines.

Logistics, Handling & Storage Requirements

Airtight Protective Packaging: Delivered securely inside an airtight, plastic-sealed containment bag with engineered internal cushioning to block environmental humidity.
Regulated Warehouse Storage: Must remain sealed in a temperature-controlled, dry, and clean environment. Store completely clear of fire hazard points, heat pipelines, or combustible matrices.
Transit Integrity Controls: Protect carefully against direct solar radiation exposure, sudden heat spikes, or unexpected precipitation during dispatch handling to avoid mechanical warping.

APPLICATION SCOPE: Standardized scientific testing and internal prototype validation loops for secondary lithium-ion, sodium-ion, and cutting-edge battery assemblies.

INSPECTION STANDARD: 100% automated visual and mechanical structural verification prior to laboratory distribution to maintain completely burr-free and oil-free operation.

IMPORTANT NOTICE: Handle with extreme care in cleanroom spaces or an anhydrous atmosphere to avoid structural wrinkles or particulate pollution. For explicit custom width, roll length, or alternative thickness options, please reach out to our team.
