Product Details

Q1: What material are silicone coasters made of? Are they safe?
A1: Silicone. It is safe, non‑toxic, and food‑safe.
Material source: Silicone is an inorganic polymer extracted from quartz sand. It is chemically stable.
Safety:

• Free from BPA — bisphenol A — plasticisers, and heavy metals.

• FDA — US Food and Drug Administration — certified as food‑safe.

• Odourless and tasteless. Unlike inferior plastics, it does not emit a pungent smell.
  Suitable for: Baby tableware, children’s drinking cups, and kitchenware — all can be used with confidence.

Q2: Do silicone coasters provide heat protection? How hot can the cups be?
A2: They offer excellent heat protection. They can withstand temperatures ranging from -40°C to 230°C.
Temperature range: -40°C to 230°C. Safe for use from the freezer to a boiling kettle.
Usage scenarios:

• Place directly under a boiling coffee pot or teapot ✅

• Place directly under a baking tray fresh from the oven ✅

• Place directly under frozen drinks ✅

• Microwave heating — the coaster itself is microwave‑safe, but is intended solely for heat insulation ✅
  Peace of mind: No matter how hot the cup, it has you covered. No matter how cold the drink, you need not worry about condensation.

Q3: Is the silicone coaster non‑slip? Will the cup slide?
A3: It offers excellent grip. It keeps your cup firmly in place.
Anti‑slip principle: Silicone has a high coefficient of friction and a slightly textured surface. This allows it to grip glass, ceramic, and mugs securely.
Base design: Most models feature suction‑cup‑style grooves or anti‑slip nubs on the base. This prevents slipping when moved — or on sloping surfaces.
Suitable cup types: Flat‑bottomed cups, round‑bottomed cups, thermos flasks, and glass tumblers can all be placed securely.
Comparison: Ceramic coasters have a smooth surface — making cups prone to slipping. Silicone coasters “grip” the cup.

Q4: How do you clean silicone coasters? Do they get dirty easily?
A4: Cleaning is incredibly simple — just wipe and it is clean. A godsend for the lazy.
Daily cleaning: Wipe with a damp cloth to remove dirt instantly — leaving no water marks.
Stubborn stains: Rinse with clean water — or gently scrub with a soft‑bristled brush dipped in neutral detergent.
Does not trap dirt: The silicone material is non‑absorbent and non‑porous. Coffee and tea stains will not seep in.
Washable: Can be rinsed directly under water — and left to air dry. Do not expose to direct sunlight.
Dishwasher‑safe: High‑quality silicone coasters are dishwasher‑safe.
Comparison: Cork coasters need to be left to dry after absorbing water. Fabric coasters require frequent washing. Silicone coasters can be wiped clean in an instant.

Q5: Do silicone coasters easily lose their shape or fade?
A5: High‑quality silicone coasters are resistant to deformation and fading.
Deformation:

• High‑quality silicone is highly elastic. It returns to its original shape after stretching.

• Prolonged heavy pressure — e.g., from heavy objects — may cause temporary deformation, but it will gradually return to normal.

• Avoid contact with sharp objects — to prevent scratching the surface.
  Fading:

• High‑quality silicone has high colour fastness. It does not fade under normal use.

• Avoid prolonged exposure to direct sunlight — UV rays accelerate ageing.

• Avoid contact with alcohol and oily solvents.
  Purchasing advice: Choose products with quality assurance. Avoid cheap, inferior silicone.

Q6: Do silicone coasters have an odour? How can it be removed?
A6: High‑quality silicone is odourless. A slight odour is normal.
Source of odour: New silicone products may have a slight mould or packaging odour. This is non‑toxic and harmless.
Removal methods:

• Rinse with clean water — and air‑dry for 1‑2 days.

• Soak in a solution of bicarbonate of soda and warm water for 1 hour — then rinse thoroughly.

• Soak in white vinegar solution — 1:10 ratio — to remove odours.
  Note: If there is a pungent chemical smell, the silicone may be of poor quality or contain recycled materials. Use is not recommended.

Q7: Can silicone coasters be used in the microwave?
A7: Yes — but only for use as a heat‑resistant mat.
The coaster itself: The silicone is microwave‑safe. With a heat resistance of 230°C, it will not melt or deform.
Usage: Place it in the microwave as a heat‑resistant mat under bowls or plates — to prevent burns.
Note: Do not use the coaster as a heating surface for tableware — e.g., placing food on it to heat. The coaster is only an auxiliary tool.

Q8: Do silicone coasters attract dust?
A8: High‑quality silicone does not easily attract dust. Poor‑quality silicone is prone to collecting dust.
Reason: The surface of high‑quality silicone is smooth. It does not easily attract static dust.
Tips for keeping dust‑free:

• Clean regularly — by wiping with a damp cloth.

• Avoid storing in dusty environments.

• Rinse with water before use.
