Instantly transforms into crispy, crunchy bread slices! This cutting-edge “pot‑bottom technology” lets your microwave bake up that same satisfying crunch.
2026-01-23 11:45

Don’t you often find yourself longing for that slice of bread, with its crisp, golden‑brown bottom and irresistible aroma, straight out of the oven?
But every time I heat it in the microwave, it always turns soggy and limp, with absolutely no texture to speak of.
Don’t worry—today I’m recommending a nifty gadget that turns your microwave into an oven in seconds—
Wave-absorbing thermal conductive silicone SH-399BK!
Experimental Comparison: Crispy vs. Soft
We conducted a small experiment:
Place identical slices of bread, one on a regular plate and the other in a frying pan lined with wave-absorbing, thermally conductive silicone, then microwave them.
The results are astonishing:

● Regular plate: The bread slices remain soft, with no crispiness at all.
● Wave-absorbing, heat-conductive silicone pan: The bottom of the bread slices turns golden and crispy, instantly elevating the texture!
Why can it “bake” a crispy crust?

This is no ordinary silicone gasket; it employs a precision molding process to directly press‑mold wave‑absorbing, thermally conductive silicone onto the bottom of the frying pan, creating a wave‑absorbing, thermally conductive structure.
It employs SH-399BK silicone rubber, specially engineered for microwave absorption and thermal conductivity, offering exceptional microwave absorption and heat‑transfer performance.
In the microwave, it rapidly absorbs microwave energy and converts it into heat, which is conducted throughout the entire bottom of the pot, delivering a truly “microwave‑baked pot” effect!
More notably, it also features intelligent temperature control:
After heating to 230°C, the temperature stops rising, preventing food from burning and significantly enhancing safety.
Advantages of Integrated Molding Technology

● More uniform heat conduction: The silicone adheres seamlessly to the pot bottom, ensuring heat transfer with no dead zones.
● Safer and more durable: No risk of detachment, with a longer service life.
● Easier cleaning: One-piece construction with no crevices to trap dirt and grime.
● More aesthetically pleasing appearance: industrial-grade molding process ensures a tight, smooth fit.
Core Product Specifications
| Project | SH-399BK |
| Appearance | Black-gray/Brown-black |
| Thermal interface layer thickness | Approximately 2 mm (molding standard) |
| Fever temperature (2 minutes) | ≥220℃ (automatic temperature control) |
| Craftsmanship | High-temperature compression molding integrated forming |
Usage Tips
● Specifically designed for microwave ovens, delivering both microwave and baking functions.
● We recommend heating for 3 minutes to achieve the ideal crispiness.
● Simply wash as usual after use; the silicone layer is washable and abrasion‑resistant.
From Industrial Technology to a Kitchen Revolution
SH-399BK microwave-absorbing thermal conductive adhesive, with its outstanding thermal conductivity and microwave absorption properties, is quietly making its way into our kitchens, delivering a brand-new heating experience.
If you’re tired of the soggy, mushy texture that microwaved food often ends up with, this one-piece, wave-absorbing, heat-conducting silicone pot is definitely worth a try!
Making breakfast bread, pizza crusts, and even frozen foods crisp again is now easy and worry-free!
Friendly reminder: Please use the microwave‑safe setting to avoid dry heating, and take care to avoid burns after use.
