Silica Gel 50g — Tyvek w/ Logo — Blue

CEMACOSG's 50g Blue-Logo Tyvek Silica Gel is the most specified mid-weight desiccant SKU for industrial electronics and precision machinery packaging — a single 50g unit handles enclosures of 50–80 litres under tropical export conditions. Tyvek (DuPont flash-spun polyethylene) is heat-stable, non-friable and lint-free — a mandatory packaging requirement for industrial-grade electronics under MIL-D-3464E.

Technical Specifications

• Net weight: 50 g (tolerance ±3%)
• Composition: Silicon dioxide (SiO₂) ≥ 99% — DMF-free, CoCl₂-free
• Moisture absorption: 30–40% by weight at 25°C / RH 90% (DIN 55473) — equivalent to 15–20 ml of water
• Packaging material: Tyvek 1073B (DuPont flash-spun PE) — non-friable, particle-free, continuous heat resistance to 70°C
• Print: CEMACOSG logo + "DO NOT EAT" warning in blue on Tyvek surface
• Standards: DIN 55473 · MIL-D-3464E · ISO 9001:2015
• Sachet dimensions: 90 × 120 mm
• Shelf life: 24 months (sealed, ≤ 30°C)

Practical Applications

• Industrial electronics & PCB assemblies: Variable frequency drives, PLCs and HMI panels exported to Japan and South Korea are typically packed in PE foam with a 50g Tyvek silica gel sachet inside. Tyvek generates no particulate matter, preventing short-circuit contamination — a hard requirement under IPC-A-610 as specified by Japanese buyers.
• Precision mechanical components: Bearings, lead screws and CNC tooling — relative humidity above 60% causes visible oxidation on carbon steel surfaces within 48 hours. The 50g sachet maintains RH below 40% in wooden crates or carton boxes throughout a 30-day sea voyage.
• Engineered wood export: MDF panels and HDF flooring in palletised bundles — one 50g sachet per layer prevents differential moisture uptake between boards, avoiding warping and surface-coating delamination on arrival.
