Sandwich Panels, Aluminum and Thermoplastics honeycombs and Foams

ALUSTEP® F is a lightweight sandwich panel with a core in aluminium honeycomb with glass fiber reinforced with phenolic resin.

pannelli sandwich Alustep F

ALUSTEP® F는 경량 샌드위치 패널로, 알루미늄 허니콤 코어와 페놀 수지로 강화 된 유리 섬유로 된 두 겹의 외장 레이어가 있습니다.

페놀 수지의 인화성이 낮기 때문에 이 패널은 조선, 열차 및 대중교통 등 운송차량에 사용할 수 있습니다. Alustep F는 IMO MED 인증 Mod에 대해 F등급을 획득했으며, 선박에 대해 B단계와 D단계를 획득하였습니다.
