| Safety(安全性) |
Extremely high. Food - grade silicone (such as medical - grade) is non - toxic, odorless, has strong chemical stability, and is not easy to release harmful substances. Suitable for long - term skin contact. |
Qualified products meet safety standards, but some low - end TPE may have trace plasticizers remaining (choose regular brands). Safety is slightly lower than that of silicone. |
| Softness(柔软度) |
Moderately hard (hardness can be adjusted, commonly 50 - 80 Shore A). The touch is rather "tough" with good resilience. |
Softer (can reach 0 - 50 Shore A). Close to the touch of human skin, with more excellent elasticity and ductility. |
| High - temperature Resistance(耐高温性) |
Excellent. Can withstand high temperatures of 100 - 200°C, suitable for boiling water disinfection and high - temperature cleaning. |
Poor. Usually, the temperature resistance does not exceed 80°C. Prone to deformation at high temperatures, and only suitable for warm water cleaning. |
| Corrosion Resistance(耐腐蚀性) |
Strong. Resistant to oil and chemical cleaning agents, not easy to be corroded by body fluids and lubricants (water - based/silicone - based). |
Weak. May swell when in long - term contact with oily lubricants. It is recommended to only use water - based lubricants. |
| Ease of Cleaning(易清洁性) |
The surface is smooth, not easy to hide dirt. Can be directly washed with water or disinfected with alcohol. |
The surface is slightly porous (high - quality TPE can be optimized). Easy to absorb dust and secretions, requiring more careful cleaning to avoid residue. |
| Durability(耐用性) |
Extremely good. Resistant to aging and tearing, with a long service life (several years), and not easy to turn yellow (for high - quality silicone). |
Moderate. Slight deformation and oil secretion may occur after long - term use (especially in high - temperature environments). The service life is 1 - 3 years (depending on quality). |
| Price(价格) |
Relatively high (high raw material cost), suitable for mid - to - high - end products. |
Lower, with high cost - effectiveness, suitable for entry - level or one - time use scenarios. |
