TPE vs Silicone: Material Comparison for Sex Toys

Bottom line: Silicone is better. Always choose silicone.

TPE (Thermoplastic Elastomer)

Pros: Soft, flexible, cheap

Cons:

• Porous (bacteria colonise)
• Cannot be sterilised
• Degrades quickly
• Contains phthalates (health concern)

Silicone

Pros:

• Non-porous (safe)
• Sterilisable (boil)
• Durable (5+ years)
• Body-safe

Cons: More expensive

The Porosity Issue

TPE is porous. Bacteria colonise the microscopic pores. Even after washing, bacteria remain.

This matters for:

• Personal use (degradation, infection risk)
• Sharing (can't be fully sterilised)

Price Reality

Silicone costs more (£15–30+ for basic toy), but lasts longer and is actually safe.

TPE is cheap but can't be shared and degrades quickly.

Verdict

Never buy TPE for penetration. Silicone-only, even if it costs more.
