Material Composition | Hygiene-focused users, medical use | - Industry: Silicone (ISO 10993 compliant) - Base: Glass (non-porous, ISO 10993)▲ - Advanced: Borosilicate Glass (heat-resistant up to 300°C, ASTM E1359)▲▲ | Base: Non-porous surface resists bacterial growth. Advanced: Enhanced heat resistance for sustained warmth. | Base: Requires pre-warming (cold to touch). Advanced: Higher cost. |
Temperature Retention | Long-term use requiring sustained warmth | - Industry: Retains body heat for ~15 mins (ISO 1164) - Base: 30 mins (37°C → 34°C)▲ - Advanced: 60 mins (37°C → 35°C, ASTM D5423)▲▲ | Advanced: Maintains warmth twice as long as industry standards. | All versions require pre-warming before use. |
Ease of Cleaning | High-maintenance users | - Industry: Soap/water (ASTM E1054) - Base: Dishwasher-safe▲ - Advanced: Non-stick coating (99.9% bacteria removal, ISO 15189)▲▲ | Base/Advanced: Easier cleaning than silicone. Advanced: Reduces residue buildup. | Base: Risk of chipping if mishandled. |
Durability | Heavy use scenarios | - Industry: Resists tearing (ASTM D5271) - Base: Withstands 50+ drop tests▲ - Advanced: 100+ drop tests▲▲ | Base/Advanced: Longer lifespan than silicone. | Glass can shatter if dropped from heights. |
Comfort | First-time users, sensitivity needs | - Industry: Flexible silicone (ISO 13485) - Base: Requires warming▲ - Advanced: Rounded edges (95% comfort rating)▲▲ | Advanced: Ergonomic design reduces discomfort. | Base: Uncomfortable when cold. |
Safety Features | Medical-grade hygiene requirements | - Industry: Non-toxic (ISO 10993) - Base: Non-porous surface▲ - Advanced: Antimicrobial coating (ASTM E2149)▲▲ | Advanced: Reduces bacterial growth by 99.9%. | Base requires manual cleaning for full hygiene. |
