The difference between silicone and TPE is porosity, not softness. Silicone is non-porous: its surface has no microscopic openings, so nothing soaks in and washing genuinely removes what is on it. TPE — thermoplastic elastomer — is porous, absorbing moisture, body fluids and lubricant into the material itself, where soap cannot reach.
That single property drives everything else: how long a toy lasts, whether it can be shared, whether it starts to smell, and whether it can ever be properly sanitised.
What is silicone good at?
Silicone tolerates heat, holds fine detail, and can be washed thoroughly without degrading. It costs more and feels slightly firmer.
Crucially, it can be boiled for three minutes — provided there is no motor or battery in it — which is the most thorough cleaning available to a home user. Nothing porous can match that.
For anything used internally, or anything you expect to own for years, it is the better buy. Our medical-grade silicone plug at ₹1,249 and rechargeable silicone massager at ₹4,499 are both effectively lifetime purchases.
What is TPE good at?
TPE feels softer and closer to skin, stretches more, and costs considerably less.
For larger items where material volume drives the price — torsos and dolls especially — TPE is what makes them affordable at all. A silicone torso costs several times what the same object costs in TPE, which is the entire reason the category exists at two price points. Our torso versus full-size guide covers that trade-off.
It is a legitimate choice as long as you know it is a consumable rather than a keeper.
How long does a TPE item actually last?
Six to twelve months of regular use, and longer with light use and a condom over it every time.
TPE almost never fails from use. It fails from trapped moisture. Wash it, then dry it completely, then dust it with renewal powder or cornstarch. Stickiness is nearly always residual moisture rather than the material breaking down — though a smell that survives a proper wash is the material, and that one is terminal.
Our stroker cleaning guide covers the drying step in detail, because it is the step that decides the lifespan.
What else damages TPE?
Two things worth knowing, both avoidable:
-
Dark or dyed fabric stains it permanently. Keep it on light colourfast material and away from new denim.
-
Sharp creases leave marks that do not come out. Never store it folded.
Silicone is far more forgiving on both counts. Warm water, mild unscented soap, rinse, dry.
What is the one thing that destroys silicone?
Silicone lubricant. It bonds with the surface, and one use is enough to start the damage — the toy turns tacky, then gummy, then pits, and none of it is reversible.
Use water-based lubricant with both materials and the question disappears. Our compatibility guide covers the household substitutes worth avoiding too.
What about ABS, steel and glass?
ABS plastic is the hard housing on vibrators and motors. Non-porous and easy to clean, but rigid — so it appears as casings and handles rather than as the contact surface.
Stainless steel and glass are both non-porous, fully sanitisable, and can be warmed or cooled for temperature play. They are also completely unforgiving on size, since there is no give at all.
That makes them excellent where you already know your size — our mirror-polished steel plug at ₹3,199 is a lifetime object — and a poor choice for a first purchase. Our steel versus silicone comparison covers the weight difference that actually decides it.
Can you tell the materials apart by hand?
Usually, yes. Silicone is matt-to-satin, drags slightly against a dry finger, holds its shape, and does not stick to itself. TPE and jelly are glossy, slick when dry, very squashy — and two of them stored touching will bond to each other over months.
A strong chemical smell out of the box is TPE off-gassing plasticiser. It fades over a week or two of airing and is worth doing before first use.
Which should you buy?
-
Internal use, long-term ownership, or anything shared: silicone.
-
Anal use specifically: silicone or steel, for the sterilisation.
-
Large items, occasional use, or a budget where the alternative is not buying at all: TPE, cared for properly.
-
A dildo you are unsure about the size of: cheap TPR to test, silicone to keep — our jelly versus silicone guide puts numbers on that.
