Squishy Materials Compared: PU Foam, TPR and Silicone
There is no single best squishy material for every person. Different squishy materials suit different preferences. Your choice depends on the feel you want, how quickly you want the item to recover its shape, and how the product is constructed. PU foam is commonly associated with airy, slow-rising designs. TPR and related thermoplastic elastomers are often used for flexible, rubber-like forms. Silicone can create soft or gel-like styles, but the exact experience still depends on formulation, shape, wall thickness and filling.
This guide compares those material families without treating a material name as a guarantee. Use it to understand listings, narrow the texture you prefer and ask better questions before buying.
What are squishy toys made of?
“Squishy” describes an interaction, not one universal material. Products sold under that name can use foam, a solid elastomer, a soft outer skin with a filling, or a layered construction. That is why two toys with similar shapes can feel completely different when squeezed.
A material label is only the starting point. Size, geometry, surface coating, internal filling and manufacturing choices also affect compression, rebound and wear. For a broader introduction to the category, read our guide to what squishy toys are.
PU foam squishies
Polyurethane, usually shortened to PU, is a broad polymer family. In the squishy category, PU foam is often used for lightweight shapes that compress deeply and recover gradually. Recovery time still varies between products, so “PU foam” alone does not tell you exactly how slow-rising a toy will be.
Typical shopping cues: a painted character or food shape, an airy feel, deep compression and a visibly slow return.
Before buying: surface paint and coatings can show wear before the foam body does. Read the listing for care instructions rather than assuming two painted foam toys will age the same way.
TPR and thermoplastic elastomers
TPR is commonly used as retail shorthand for thermoplastic rubber. A more technical umbrella term is thermoplastic elastomer, or TPE. The IUPAC Gold Book defines a thermoplastic elastomer as an elastomer with a thermoreversible network. In shopping language, this family is associated with flexible, rubber-like products that can bend, stretch or spring back.
Typical shopping cues: a dense or rubbery feel, strong stretch in designs meant for stretching, and often faster recovery than many slow-rising foam shapes. Some products use a TPR-style outer shell around a filling, which feels different from a solid piece.
Before buying: “TPR” does not disclose the exact formulation or construction. Check whether the listing describes a solid toy, a filled toy or a skin-based design—those details often matter more to the squeeze than the short material label.
Silicone squishies
Silicone squishies are usually chosen for a soft, elastic or gel-like interaction, but the category is not one texture. A solid molded piece, a thin silicone skin and a filled silicone construction can behave very differently. Formulation and curing also influence the final feel, so the word “silicone” cannot predict exact softness or rebound by itself.
Typical shopping cues: a smooth or tacky surface, soft deformation and an elastic return—or, in some designs, a more moldable response. Product photos and short demonstration videos help more than a broad material claim.
Before buying: look for construction details rather than relying on a vague “premium silicone” line. Browse our current silicone squishy collection, then confirm details on the individual product page.
Filled squishies are a construction, not a fourth material
Some products combine an outer skin with gel, beads, liquid-like filling or decorative pieces. In those cases, the squeeze comes from the whole construction: skin thickness, filling movement, air space and shape. Calling the product “silicone” or “TPR” may describe the outer layer but not the full experience.
On LoveSquishy, examples you can compare include:
- Coconut Oil Squishy — glossy, translucent, gooey ball described as non-rebound (holds a dent); firmness can vary by colorway.
- Slushy Apple Squishy — jelly, crunchy and moldable variants; the listing states not every apple option is slow-rising.
- Toothpaste Squishy — clear jelly with glitter and charms in a toothpaste-inspired form; texture can vary by design.
Non-rebound vs slow-rising: performance terms, not materials
Slow-rising describes a toy that gradually returns toward its original shape after compression. Non-rebound is often used for a toy that stays deformed longer, can be reshaped, or has very little immediate recovery. Sellers do not always use these terms consistently, so treat them as behavior descriptions—not standardized material categories—and they are not synonyms.
A silicone squishy can be designed for quick recovery or for a more moldable response. PU foam products can also have different recovery speeds. If rebound matters to you, watch a continuous squeeze-and-release video of the exact product. LoveSquishy’s Coconut Oil listing defines non-rebound as holding part of the squeezed shape instead of springing back right away; its Apple listing separately notes that not every variant is slow-rising.
Quick comparison table
| Construction or label | Common feel | Rebound pattern | What to check on the listing |
|---|---|---|---|
| PU foam | Light, airy and deeply compressible | Often slow-rising, but speed varies | Coating, care notes and demonstration video |
| TPR or TPE-style elastomer | Dense, flexible or rubber-like | Often springier than slow-rising foam | Solid vs filled construction; stretch behavior |
| Silicone | Soft, elastic, tacky or gel-like depending on design | Can range from quick return to moldable | Solid vs skin-based construction; product-specific details |
| Filled construction | Movement and pressure shift inside the outer skin | Depends on skin, filling and air space | Outer material, filling description and care notes |
How to choose: feel first, then read the listing
- Start with the motion you want — gradual rise, quick spring-back, stretch, or a moldable feel.
- Identify the construction — foam, solid, hollow, layered or filled—not only one material word.
- Watch the exact product in use — a continuous squeeze-and-release clip shows movement that a still photo cannot.
- Read the listing for the details that change the squeeze — outer material or body material, whether it is filled, approximate dimensions, rebound description, care notes and any applicable age or use warnings.
- Match care expectations to the surface — painted foam, tacky elastomers and filled skins may need different handling. See our care guide by construction.
If you are still comparing shapes and experiences, our squishy toy buying guide turns those preferences into a shortlist. Follow the product-specific age and use guidance as well as the material description.
Frequently asked questions
Is silicone better than PU foam for squishies?
Not universally. Choose silicone when the demonstrated product has the elastic or moldable feel you want. Choose PU foam when you prefer a lightweight, airy squeeze and gradual recovery. Compare the demonstrated products rather than choosing a winner from the material label alone.
Are TPR and silicone the same material?
No. TPR usually refers to a thermoplastic rubber or thermoplastic elastomer family, while silicone is a different polymer family. Both can produce flexible products, but formulation and construction determine the final feel.
Does non-rebound mean the squishy is made of silicone?
No. Non-rebound describes how a product behaves after squeezing; it is not a standardized material label. Confirm the material and watch the exact product recover before choosing.
