How to Choose Heat-Resistant and Impact-Resistant Melamine Tableware

How to Determine the Heat Resistance and Impact Resistance of Melamine Tableware?

High-quality melamine tableware exhibits excellent heat resistance and impact resistance, while low-quality melamine tableware may deform, crack, or even release harmful substances when exposed to high temperatures or impacts. Below is a comparative analysis and testing methods:

1. Heat Resistance

(2) Heat Resistance Testing Methods

✅ Boiling Water Test (Pour boiling water into the tableware and leave it for 5 minutes)

• High-quality melamine: No deformation, no odor, smooth surface remains intact.

• Low-quality melamine: May slightly deform or emit odors; some poor-quality versions may soften.

✅ High-Temperature Steam Test (Place in a steamer for 10 minutes)

• High-quality melamine: Maintains its shape, does not discolor, and does not emit odors.

• Low-quality melamine: May yellow, deform, or emit a plastic or chemical smell.

✅ Microwave Test (Only for melamine labeled as microwave-safe)

• High-quality melamine: Can withstand short heating times (≤ 2 minutes) without deformation or odor release.

• Low-quality melamine: Softens, emits odors, or even cracks after heating.
  ⚠ Note: Most standard melamine tableware is not microwave-safe.

2. Impact Resistance

(2) Impact Resistance Testing Methods

✅ 1-Meter Drop Test (Simulates accidental falls during daily use)

• High-quality melamine (A8/A5): Generally does not break; may show minor surface scratches.

• Low-quality melamine (A1/recycled): Prone to breaking; fractures may be sharp and dangerous.

✅ Metal Spoon Tapping Test (Tap the surface with a metal spoon and listen for sound clarity)

• High-quality melamine: Produces a crisp sound, and the surface remains intact without cracks.

• Low-quality melamine: Produces a dull sound and may develop cracks or damage.

✅ Cold-to-Hot Stress Test (Freeze for 2 hours, then pour in hot water)

• High-quality melamine: No cracks or deformation, remains intact.

• Low-quality melamine: May develop cracks or warping.
