Product overview
Rogers HT-880 is a cellular silicone foam for sealing duty that ordinary organic foams cannot survive. Silicone chemistry keeps the foam flexible from deep cold to sustained high temperature, resists UV and ozone ageing, and does not harden or crumble with time — so the gasket still seals after years of thermal cycling.
DINGGU Tape supplies this grade as original manufacturer material and converts it on our own slitting, die-cutting and lamination lines. You can order it in roll form, or as finished parts made to your drawing — pads, strips, gaskets and multi-layer builds — with lot-level traceability on every delivery.
Construction and materials
Technical data
The values below are typical reference ranges for the BISCO cellular silicone foam family, provided to help you shortlist a construction. They are not reproduced from a manufacturer datasheet and are not a specification. Before release to production, confirm the figures for Rogers HT-880 against the current technical datasheet issued by Rogers.
| Material | Cellular silicone foam |
|---|---|
| Density range | approx. 190 – 400 kg/m³ across the family (typical) |
| Service temperature | −55 °C … +200 °C continuous (typical) |
| Short-term peak | up to +260 °C (typical, grade-dependent) |
| Ageing resistance | Excellent resistance to UV, ozone and long-term heat ageing |
| Thickness range | 0.5 – 12.7 mm across the family |
| Flammability | UL 94 V-0 and flame-block grades available within the range |
| Compression set | Low — retains sealing force through thermal cycling |
| Adhesive option | Available plain or PSA-laminated for assembly |
| Substrate note | Silicone-safe design required — avoid contact with silicone-sensitive optics |
Typical applications
- High-temperature gasketing in lighting and power equipment
- EV battery thermal barrier and compression pads
- Aerospace and rail interior sealing with fire performance requirements
- Environmental seals on outdoor enclosures exposed to UV
- Oven, appliance and industrial process door seals
Application guidance
- Design compression to the grade’s recommended range for a lasting seal
- Confirm flame and smoke requirements at assembly level, not material level alone
- Avoid silicone contamination of surfaces that will later be painted or bonded
- Use PSA-laminated stock for repeatable placement on production lines
- For continuous seals prefer die-cut frames over spliced strips
Supply and conversion
