Extreme thermal endurance is essential for oven-to-table performance. This feature ensures that kitchenware remains structurally sound and safe at professional-grade temperatures up to 250°C, providing a benchmark for high-performance functionality.
The Science of Extreme Heat Endurance
At 250°C, most consumer plastics would melt or ignite. Heat resistance at this level is reserved for premium materials like borosilicate glass, cast iron, and high-performance technical ceramics. These materials have an incredibly low "coefficient of thermal expansion," meaning they do not significantly expand or contract when heated. This molecular stability prevents "thermal shock"—the cracking that occurs when a hot dish is moved to a cool surface—and ensures that the material does not break down or outgas even under the intense infrared radiation of an oven broiler.
Validation through the High Performance Mark
By meeting selected technical benchmarks, your kitchenware products become eligible for the Intertek High Performance (HP) Mark’s Heat-Resistance (250°C). products are tested to BS EN 13834, clause 6.1.9. The tested samples must display no signs of damage after testing.
This mark serves as a ‘proof of performance’ by validating that your product meets the High-Performance Mark standards. You can display the mark on product tags, brochures, packaging, and across all sales channels to confidently signal that your product's performance claims are verified.
