Anti-static polar-insulation-case from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 100, 12h quote, 25-day delivery to 47 countries.
Buyers who care about Anti-static polar-insulation-case certifications usually do so for a reason: their end customer requires it, or their insurance demands it, or their industry standard mandates it. We have shipped to all three.
For your reference, here are the WL series models we typically use for Anti-static polar-insulation-case applications. Outer dimensions (OD) are measured to the outside of the case; inner dimensions (ID) reflect the usable cavity after subtracting wall thickness. All in millimeters; imperial dimensions in our catalog PDF.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL1204 | 120×90×40 mm | 115×78×32 mm | 100 g | PP | Phone / Wallet |
| WL2005 | 195×170×46 mm | 190×135×40 mm | 175 g | PP | Action Camera / GoPro |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP | Tablet / E-reader |
The most common model for "Anti-static polar-insulation-case" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
All Anti-static polar-insulation-case cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/m³). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
The shell is rated IP68 (submersible 5m / 30 min) ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -30 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
In 2024, we shipped Anti-static polar-insulation-case for: (1) Film production — ARRI Alexa Mini + accessories in custom foam. (2) Drone operators — DJI Mavic 3 + RC + 6 batteries. (3) Broadcast — RED Komodo + 2 lenses + monitor. (4) Military — rifles + scopes + ammo. (5) Medical — first aid kits + AED.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
After Anti-static polar-insulation-case ships: (1) We send QC photos before shipment. (2) Lot certificate with serial numbers. (3) 90-day defect replacement. (4) Foam re-cut service for equipment changes. (5) 5-year case body warranty. (6) Tooling stored 3 years for easy reorder.
If a competitor claims IP67 but cannot produce a third-party certificate, ask them why. We always can.

PP and PP+GF cases are 100% recyclable. We have a take-back program for end-of-life cases from large customers (1,000+ units / year): we collect, shred, and reuse the regrind in non-critical components.
All IP ratings are third-party tested by SGS, TUV, or Intertek at our lab in Zhongshan, Guangdong. We test every new mold design to IP67 and select models to IP68. Test certificates are dated and serialized.
MIL-STD-810H is the US Department of Defense test standard. Our cases pass Method 501.7 (high +70°C), 502.7 (low -40°C), 514.8 (vibration), 516.8 (26 drops at 1.2m), 506.6 (rain / water penetration). Used by armed forces in 30+ countries.
