Not all squishy materials are created equal. The material determines how long the toy lasts, how safe it is, how it feels, and whether it maintains quality over time.
The Best Material: Food-Grade Silicone
Food-grade silicone is the gold standard for squishy toys:
Durability — Chemically stable and resistant to UV light, oxygen, and temperature changes. Feels identical on day 1 and day 1000.
Safety — Non-toxic, BPA-free, phthalate-free, and hypoallergenic. Same material used in baby bottle nipples and medical devices.
Tactile quality — Compresses deeply and rebounds slowly (3-5 seconds). Stays consistent indefinitely.
Odorless — Unlike foam squishies.
Washable — Soap and water. Doesn't absorb liquids or harbor bacteria.

Other Materials: When They Work
TPR (Thermoplastic Rubber)
Best for: Mid-range squishies where cost matters more than longevity.
Cheaper than silicone, more durable than foam. Quality varies.
Polyurethane Foam
Best for: Short-term novelty squishies where durability doesn't matter.
Very soft, very cheap, elaborate designs possible. Degrades within weeks to months.
Gel-Filled
Best for: Stress balls where you want firm push-back rather than slow rise.
Cool to the touch, firm resistance, fast rebound. Can puncture and leak.

| ## Frequently Asked Questions | ||
| ### What is the best material for squishy toys? | ||
| Food-grade silicone. Durable (lasts years), safe (non-toxic, BPA-free), odorless, washable, and maintains consistent slow-rise quality indefinitely. | ||
| ### Is silicone or foam better for squishies? | ||
| Silicone is better. Lasts years, odorless, safe, and maintains the same tactile quality forever. Foam degrades within weeks. | ||
| ### What makes food-grade silicone safe? | ||
| Non-toxic, BPA-free, phthalate-free, and hypoallergenic. Same as baby bottle nipples and baking molds. Doesn't leach chemicals. | ||
| ### Why are foam squishies bad? | ||
| Degrade quickly (weeks to months), develop chemical smells, can't be washed, and often contain harmful chemicals. | ||
| ### What is TPR in squishies? | ||
| Thermoplastic rubber — a blend of plastic and rubber. More durable than foam but less durable than silicone. | ||
| ### How long do silicone squishies last? | ||
| Essentially permanent with normal use. | ||
