Composite polyester-based foam core material "ST-Eleveat"
It contributes to the lightweighting of FRP molded products with excellent heat resistance and shape flexibility.
"ST-Eleveat" is a material made of bead foam, which allows for shape formation using molds. It reduces the cutting processes required for conventional board foams, contributing to material waste reduction, and offers mass production capabilities suitable for medium to large lots. ✔ Type: Eleveat BIO E (150g/L) ✔ Particle Diameter: Approximately 2.5mm ✔ Adoption Record: Used in FRP wind turbine blades and mobility parts Expected Applications: Propeller core materials, composite materials using RTM method 【Features】 - A lineup centered on biomass grades, contributing to the environment - Superior thermal dimensional shrinkage and chemical resistance compared to conventional foamed materials - High design flexibility, capable of reproducing shapes that are difficult with board core materials - Proven track record of mass production adoption for Japanese automotive OEMs (interior parts/core materials for composites) 【Exhibition Participation】 September 18-20: SAMPE Japan Advanced Materials Technology Exhibition Booth: S-42 October 9-11: N-Plus Product Development Technology Exhibition Booth: NCC Pavilion C-66 We will also be exhibiting at the trade shows, so please feel free to visit us.
