Silicone vs TPE: which material to choose and why it matters
The first question before buying a realistic companion body: the real differences between silicone and TPE in feel, lifespan, care and price.
The short answer
If you want something that lasts and is easy to maintain, choose silicone. If you prioritize a softer feel and a lower price, choose TPE. Neither is simply better: one is better for you depending on budget, use and patience for upkeep.
Silicone: pricier, longer-lasting
Quality silicone is non-porous: it doesn't absorb liquids or odors, tolerates heat better and cleans more easily. Its downsides are a firmer feel and a higher final price because it costs more to manufacture.
A useful rule: never use silicone-based lubricant on silicone, because it breaks down the surface. Water-based lubricant is the safe choice.
TPE: softer, more delicate
TPE (thermoplastic elastomer) feels softer and more elastic, which is why most budget figures use it. In exchange it is porous: it absorbs oils, holds odors if not dried thoroughly and can stain from dark clothing dye or newsprint.
With basic care — drying completely, the powder the maker recommends, light-colored clothing — it lasts years. Without it, it degrades fast.
How to decide in a minute
Bigger budget and little appetite for upkeep: silicone. Tighter budget and soft feel first: TPE. If you're unsure, start with a torso (much cheaper and easier to store) to learn which material you like before investing in a full-size figure.
And be wary of any listing that doesn't state the material clearly: when it doesn't say, it's usually not the one you hoped for.
