Silicone vs PVC: Which Material Should Your Custom Product Use?
8 min read · updated 2026-10-19
Choose silicone when the part touches skin, food or heat above 70 °C, or has to stretch repeatedly. Choose PVC when you need sharp multi-colour detail at low tooling cost and the product stays at room temperature.
The ten differences that actually matter
| Property | Silicone (HCR / LSR) | Soft PVC |
|---|---|---|
| Service temperature | −40 to 200 °C continuous | −10 to 60–70 °C |
| Skin contact | Inert, widely used for wearables | Contains plasticiser; restricted in toys |
| Detail and sharp edges | Softer edges, 2–4 moulded colours | Sharp edges, fine text, 8+ colours |
| Stretch and recovery | High; returns to shape | Limited; deforms permanently |
| Tear resistance | High (grade dependent) | Moderate |
| Tooling cost | Steel mould, higher | Copper mould, cheaper |
| Typical MOQ | 100–500 pcs | 100–500 pcs |
| Surface feel | Matte, rubbery, soft-touch | Smooth, slightly glossy |
| Ageing and yellowing | Stable; does not yellow | Can yellow and stiffen |
| Regulatory direction | No PFAS by chemistry; D4/D5/D6 restricted in EU | Lead and phthalate limits tightening |
Why the regulatory column now matters
Compliance cost for PVC has been rising since 2024 and is still rising. The EU restricts lead in PVC articles above 0.1 %, keeps reviewing phthalate plasticisers, and has been moving towards broad PFAS restrictions. Silicone does not contain PFAS by chemistry, so it sidesteps that whole category of risk.
Silicone is not automatically compliant, though. Siloxanes D4, D5 and D6 are restricted separately under REACH Annex XVII (Regulation 2024/1328), so a compliant formulation and a third-party REACH file are still needed. Anyone who tells you silicone is unconditionally compliant is overselling.
30-second decision list
- Touches food, drink or a child’s mouth → silicone
- Sits near heat above 70 °C, or in a car → silicone
- Worn against skin all day → silicone
- Needs to stretch and spring back → silicone
- Thin lines, small text, or more than four colours → soft PVC
- Flat 2D promotional item at the lowest unit cost → soft PVC
- Will be stored for years and must not yellow → silicone
The cost question, honestly
Tooling is where the two diverge most. A copper mould for soft PVC is materially cheaper than a steel compression mould for silicone, so at low volumes PVC often wins on landed cost even though the material is not cheaper.
At higher volumes the gap closes, because silicone parts usually need no painting — colour is moulded in — while multi-colour PVC needs spray masks and pad printing as separate operations. Above roughly 20,000 pieces, the finishing cost of a complex PVC design often closes the tooling gap.
What we do
We mould both, so the recommendation does not depend on which one we would rather sell. Send the artwork and the end-use and we will tell you which material will actually look and perform right — including when the answer is PVC.
