Question 1

What is the difference between silicone PET leather and regular silicone leather?

Accepted Answer

Regular silicone leather typically uses a woven fabric or non-woven substrate bonded with a full silicone coating. Silicone PET leather specifically uses PET (polyethylene terephthalate) as the base substrate, which provides superior dimensional stability, tear strength, and flatness — making it ideal for large-format wall paneling and precision-cut 3C accessories. The PET base also enables a smoother, more consistent surface finish.

Question 2

Can silicone PET leather be used for outdoor wall applications?

Accepted Answer

Yes, with caveats. The silicone surface layer is fully UV-stable and waterproof. However, the PET substrate can absorb moisture at the edges if not properly sealed, and the material is not inherently flame retardant. For outdoor applications, sealed edge profiles are recommended. For covered outdoor spaces such as patios and balconies, silicone PET leather performs excellently.

Question 3

How do I clean and maintain silicone PET leather wall panels?

Accepted Answer

Routine maintenance is simple. For dust and light soiling, wipe with a dry or slightly damp microfiber cloth. For grease, ink, or stubborn marks, use a cloth dampened with isopropyl alcohol (75%) or a mild neutral detergent. Avoid abrasive scrubbers, strong acids, or alkaline cleaners. The silicone surface will not degrade from alcohol cleaning — a significant advantage over PU and PVC materials.

Question 4

Is silicone PET leather suitable for children's products or healthcare environments?

Accepted Answer

Yes. The silicone coating meets FDA 21 CFR 177.2600 for food-contact safety and is free from phthalates, BPA, formaldehyde, and heavy metals. The material is hypoallergenic and naturally antibacterial. For healthcare or children's product applications, we can provide additional test reports including ISO 10993-5 biocompatibility and EN 71-3 toy safety migration upon request.

Question 5

What customization options are available for silicone PET leather?

Accepted Answer

TOPSUN offers comprehensive customization: colors (Pantone matching available), surface textures (smooth, grained, nappa, suede-touch), embossed patterns (geometric, organic, brand logos), thickness (0.6mm to 1.2mm standard, custom available), and backing treatments (pressure-sensitive adhesive, hot-melt, or plain). Minimum order quantities vary by customization complexity.

Question 6

Is silicone PET leather flame retardant?

Accepted Answer

No — silicone PET leather is not inherently flame retardant due to the combustible nature of the PET substrate. For applications requiring fire-rated materials, such as commercial buildings with specific fire codes or public transportation interiors, additional flame-retardant treatment or a certified fire-barrier layer must be specified.
