Boilproof

Boilproof is a descriptive term used in product labeling and materials science to indicate that a material or component can withstand boiling temperatures—typically around 100°C—for a defined period without excessive degradation. It is not a formal standard, but a marketing or convenience label.

In materials science, boilproof can refer to polymers, elastomers, metals, ceramics, or composites that retain structural integrity and function when exposed to boiling water or repeated boiling cycles. Performance depends on composition, exposure duration, and water chemistry. Common associations include certain high-temperature silicones, glass, stainless steel, and some stabilized plastics, though no universal guarantee applies.

In consumer goods, boilproof labels appear on cookware components, teapots, water bottles, and heat-resistant textiles. The term can also denote suitability for boiling or autoclave-like sterilization, but many items are rated only for specific conditions. Always consult the manufacturer's data for tested temperatures and immersion times.

Limitations: boiling can cause thermal stress, hydrolysis, or adhesive failure in some materials. "Boilproof" does not imply universal performance and should be viewed as conditional on tested parameters.

Etymology and usage: The term derives from boil and proof, forming an informal label whose precise meaning varies by industry and brand.
