Frequently Asked Questions — Silicone Pads

Quick answers to the questions engineers ask us most.

What temperature can silicone pads withstand?

Standard VMQ pads operate from -60°C to +200°C. High-temperature grades reach +300°C continuous — ideal for heat press and oven applications.

What is the thinnest / thickest silicone pad you can make?

We produce sheets from 0.5 mm to 10 mm by calendering, and thicker pads (up to 25 mm+) by molding or lamination, with tolerances to ISO 3302 M2.

Can you make silicone pads with adhesive backing?

Yes. We laminate 3M (467MP, 468MP, 9448A), tesa or custom acrylic/silicone PSA with die-cut or roll formats, and provide peel-strength test reports.

What is the MOQ for custom silicone pads?

Die-cut pads from standard sheet: 100 pcs. Custom molded pads: 500 pcs. Larger volumes reduce unit cost significantly.

How long does production take?

Samples: 1–3 days for die-cut, 3–5 days for molded. Mass production: 7–15 days depending on quantity.

Are your silicone pads food grade?

Yes, our food grade pads comply with FDA 21 CFR 177.2600 and LFGB / EU 10/2011. COA is provided with every batch.

What thermal conductivity do your thermal pads offer?

1.0 to 6.0 W/mK, tested to ASTM D5470. Tell us your heat source and gap thickness and we’ll recommend a grade.

Can you make pads without a drawing?

Yes — send a photo with dimensions, a physical sample, or describe the application. Our engineers reverse-engineer and send a DFM report before quoting.
