Material Comparison: TPE vs Silicone Menstrual Cup (Beginners Guide)

Most cups use menstrual cup materials like TPE or silicone PubMed Central notes these make up 90%+ of options, alongside some natural rubber, all tested for body contact. No need for fancy jargon; here's the easy difference.​

What is TPE?

TPE menstrual cup means thermoplastic elastomer. It’s a soft, flexible plastic that becomes adaptable with body heat.

• It softens when warmed by the body, which can make insertion and removal easier.
• It often has a gentler grip against the vaginal walls.
• It’s generally more affordable than silicone-based cups.

Comfort and Fit of Silicone Menstrual Cups for Beginners

Silicone cups stay soft and squishy, making them easier to insert and take out. Some helpful tips for beginners: fold the cup in a "C" shape, use a bit of water-based lubricant if needed, and try to relax your pelvic muscles.
