Silicone Rubber
Extruded, molded, or custom-converted silicone elastomer routes for seals, gaskets, tubing, and flexible parts.
Temperature stableLow compression set
Semperit — Semperit silicone elastomer programs for controlled industrial qualification.
Compare silicone rubber, silicone grease, MicroSi compounds, and polymer support options with cleaner evidence, faster sampling notes, and procurement-ready technical language.
Specification Matrix
Compare the data families buyers ask for before approval.
| Parameter | Review Range | Procurement Note |
|---|---|---|
| Durometer | 40A to 80A programs | Matched to sealing force or pump transfer need |
| Biocompatibility | USP Class VI / ISO 10993 screening | Confirm scope before medical qualification |
| Extractables | Application dependent | Document cleaning and contact media early |
| Parameter | Review Range | Procurement Note |
|---|---|---|
| Temperature | High heat service windows | Check cycling, compression, and exposure time |
| Chemical Resistance | Broad solvent compatibility | Validate against actual process chemistry |
| Format | Tape, film, skived sheet | Quote by thickness, width, and roll length |
| Parameter | Review Range | Procurement Note |
|---|---|---|
| Gauge | Thin film through rigid sheet | Tolerance drives converting performance |
| Surface | Printable, sealable, low-friction | State the downstream line conditions |
| Compliance | Food contact or electronics use | Request regulatory scope with the quote |
Product Families
Three practical starting points for silicone material selection.
Silicone Grease
Interface lubrication and protection programs for seals, connectors, maintenance kits, and controlled assembly operations.

MicroSi Compounds
Specialty compound review for electronics, medical, and precision component teams that require tighter data language.

Each Semperit review moves from chemistry to supply reality.
01
Application window first
Before grade discussion, Semperit frames temperature range, expected movement, contact fluids, substrate surface energy and target service interval so unsuitable materials are removed early.
02
Process data stays attached
Material recommendations include conversion notes for extrusion, injection molding, coating or laminating so buyers can evaluate the cost of processing, not only the nominal resin price.
03
Compliance mapped to end use
Regulatory conversations are linked to geography, food-contact exposure, automotive documentation, medical risk and customer restricted-substance lists rather than treated as generic certificates.
