How Condoms Are Made — Manufacturing, Testing & CE Certification | ULEX®

By ULEX® Editorial Team • 6/2/2026

How Condoms Are Made

Step 1: Natural Latex Harvesting

All ULEX® Premium Condoms start with natural rubber latex from Hevea brasiliensis trees. The latex sap is collected, preserved with ammonia, and transported to the manufacturing facility.

Step 2: Compounding

The latex is compounded with:

  • Sulfur: for vulcanization (cross-linking the rubber)
  • Zinc oxide: accelerates vulcanization
  • Antioxidants: extend shelf life
  • Preservatives: prevent microbial growth

Step 3: Dipping

Glass or metal formers (shaped like a penis) are dipped into the compound latex bath — typically 3 times to build up the correct wall thickness (0.06mm for ULEX® ultra thin variants).

Step 4: Vulcanization

The dipped formers pass through an oven where heat triggers vulcanization — the process that transforms liquid latex into elastic, resilient rubber.

Step 5: Stripping and Rolling

The dried condom is stripped from the former and the rim is rolled to create the characteristic rolled-base look.

Step 6: 100% Electronic Testing

Every single ULEX® condom undergoes electronic pinhole testing — a low electrical current is passed through the condom. Any pinhole creates a circuit, flagging the unit for rejection.

Step 7: Statistical Testing

Randomly selected units are tested for:

  • Air burst (volume and pressure) per ISO 4074
  • Water leak test
  • Tensile strength (elongation at break)
  • Freedom from holes test

Step 8: TÜV Rheinland Certification

ULEX® submits manufacturing processes and product samples to TÜV Rheinland — an independent German testing laboratory — for annual certification. This voluntary certification goes beyond the mandatory CE 0197 requirement.

Step 9: Lubrication and Packaging

Certified condoms are lubricated with premium silicone lubricant and sealed in individual foil wrappers. 14 units are packed in the ULEX® Premium box.

CE 0197 Marking

The CE 0197 marking on every ULEX® box confirms that the product has been assessed by Notified Body 0197 and meets the requirements of EU Regulation 2017/745 (Medical Devices).

ULEX® Premium Condoms — made with precision, tested with rigor, delivered discreetly across Europe.
