ATE die-cuts PORON, BISCO and Volara foams, as well as generic PE, PU and EPDM foams, into parts machined to your dimensions, with or without adhesive. Rotary die-cutting delivers a tolerance under 0.1 mm depending on the product. Delivered in rolls, sheets or individual parts, laminated on one or both sides where needed, from our production sites in France and Germany. Family selection is based on your service environment: continuous and peak temperature, flame-resistance requirement, chemical exposure.
What actually sets PORON and BISCO apart ?
What is PORON® foam?
PORON® is a microcellular polyurethane foam manufactured by Rogers Corporation. It is chosen for its compression set resistance and its ability to recover its shape after repeated compression, within a service range of -40°C to +90°C.
It is the first choice for shock management, sealing or electronic insulation, where the service temperature stays moderate.
What is BISCO® foam?
BISCO® is a family of technical cellular silicones, also manufactured by Rogers Corporation. Its service range is markedly wider, -55°C to +200°C, with grades certified UL94 V-0 and HF1 for flame resistance.
The first criterion for choosing between PORON® and BISCO® is therefore not “which one is better”, but the application’s actual temperature and whether a flame-resistance requirement applies.
The foams families we convert
| Family | Key characteristic | Typical uses |
|---|---|---|
| PORON® | Microcellular polyurethane foam, -40°C to +90°C, compression set resistance | Gaskets, shock management, sensitive electronic applications |
| BISCO® | Technical cellular silicones, -55°C to +200°C, certified UL94 V-0/HF1 | Insulation and sealing at extreme temperatures, flame-resistance requirements |
| Volara® | Irradiation cross-linked polyolefin, closed-cell. Temperature range not published by the manufacturer to date | Padding, cushioning, packaging liners, automotive applications |
| PE, PU, EPDM | Generic foams, temperature range varies by grade | Non-critical applications, controlled cost |
Non-exhaustive selection. Over 700 raw materials in stock. The final choice is validated on your temperature / constraint pairing: see our dedicated page on flexible materials and technical foams.
Why die-cut foam rather than raw sheet stock?
A foam only delivers its performance at the exact geometry of the joint or bearing surface: contact area, constant thickness, dimensional stability under repeated compression. Die-cut to size, it becomes a reproducible assembly component from one part to the next, rather than a material your production line still has to trim.
Delivery formats
- Parts cut to shape: ready to fit, with or without adhesive.
- Single- or double-sided lamination: the foam is supplied with adhesive already applied, ready for direct assembly on your line.
- Rolls, sheets or individual parts: depending on your volume and supply model.
- Pull tabs: optional, to ease handling of thin parts in production.
The ATE method
Family selection isn’t made from a manufacturer catalogue alone. Our teams start from your service environment (temperature, flame-resistance requirement, chemical exposure), then validate with samples cut to your dimensions. Rotary die-cutting holds a tolerance under 0.1 mm depending on the product. IATF 16949 certified, we guarantee full traceability and systematic inspection, with production sites in France and Germany.
Your application deserves the right foam. Let's talk.
Send us your drawing, your temperature environment and your main constraint (sealing, insulation, shock absorption): our teams validate the right family and deliver samples cut to your dimensions. Contact ATE, production sites in France and Germany.
The first criterion is the actual service temperature: PORON covers -40°C to +90°C, BISCO -55°C to +200°C with grades certified for flame resistance (UL94 V-0/HF1). Above 90°C, or where a flame-resistance requirement applies, BISCO is the family to consider first.
Yes, single- or double-sided lamination is available: the foam is supplied with adhesive already applied on one or both sides, ready for direct assembly on your line, in rolls, sheets or individual parts.
Rolls, sheets or individual parts, with optional pull tabs to ease handling in production. Format is chosen based on your volume and your assembly-line integration method.
