- Overview
- Technical Data
Overview
ST-Eleveat is foamed plastics foam with excellent heat resistance, flame retardancy, heat insulation and light weight. Especially suitable for use under a high-temperature conditions.
E Series : Polyester bead foam
Features
- ・High heat resistant
-
E Series : 180℃×168hrs
- *The dimensional shrinkage under static temperature conditions is 1% or less.
- ・Flame retardancy
-
Passes to FMVSS302 standard.
- Passes to "V-2" in the UL94 standard flame resistance test.
- ・Light weight
- ST-Eleveat is 80-90% lighter compared to non-foamed plastic molded products.
- ・Moldable into a wide range of shapes:
- In principle, ST-Eleveat E type can be processed on the same molding machines which are designed for processing of EPS. It is also possible to make a form core material of CFRP / GFRP composite structure.
Applications
- ・Automobiles / Transportation
- ・Aircraft / Ships
- ・Electronic devices
- ・CFRP / GFRP foam-core sandwich Structure
Product lineup
- ・ST-Eleveat BIO / RNW E
- Environmentally friendoly product utilizing biomass-derived / recycle-regin plastics.
