CASCELL® FR is a rigid PMI foam that is specifically designed for applications requiring fire resistance. It is self-extinguishing, meaning it has the ability to stop burning once the ignition source is removed. CASCELL® FR foam finds particular suitability in industries such as rail vehicle and watercraft construction, as well as the aeronautic industry. It can be processed using various techniques including prepregs (pre-impregnated composite materials), vacuum infusion methods (such as RTM and VARTM).
Features of CASCELL® FR
Fire resistance: CASCELL® FR foam
is formulated to possess fire-resistant properties. It is self-extinguishing, which means it can resist and stop burning once the source of ignition is removed. This characteristic makes it a suitable choice for applications where fire safety is a critical consideration.
Application in rail vehicle and watercraft construction: CASCELL® FR foam is particularly well-suited for use in rail vehicle and watercraft construction. These industries have strict safety regulations and requirements, and the fire-resistant properties of CASCELL® FR make it an ideal choice for various components and structures in these applications.
Aeronautic industry: CASCELL® FR foam also finds applications in the aeronautic industry, where fire safety is of paramount importance. It can be used in the manufacturing of aircraft components and structures that require fire resistance, contributing to the overall safety of the aircraft.
Processing methods: CASCELL® FR foam can be processed using various techniques, including prepregs, which are composite materials impregnated with resin in advance. Additionally, it is compatible with common vacuum infusion methods such as Resin Transfer Molding (RTM) and Vacuum Assisted Resin Transfer Molding (VARTM). These processing methods offer flexibility and versatility in incorporating CASCELL® FR foam into composite structures.
How to CASCELL® FR
Material preparation: Ensure that you have the required quantity of CASCELL® FR foam sheets or blocks for your application. Store the foam in a clean, dry, and controlled environment to maintain its quality and performance.
Design and cutting: Determine the dimensions and shape of the foam needed for your specific application. Use appropriate tools such as saws, routers, or water jet cutting machines to cut the CASCELL® FR foam to the desired size and shape. Follow recommended cutting techniques and safety precautions.
Surface preparation: Clean the surface of the CASCELL® FR foam to remove any dust, debris, or contaminants. This can be done using a soft brush, compressed air, or a lint-free cloth. Ensure the surface is clean and dry before proceeding to the next step.
Adhesive application (if required): If bonding or laminating CASCELL® FR foam to other materials, apply an appropriate adhesive according to the manufacturer's instructions. Ensure proper coverage and even distribution of the adhesive. Use compatible adhesives that are suitable for fire-resistant foam materials.
Assembly and curing: Position the CASCELL® FR foam in the desired location or mold. If using composite materials, such as prepregs, follow the recommended lay-up process and ensure proper alignment and consolidation. Apply appropriate pressure or vacuum as needed for the chosen processing method, such as RTM or VARTM. Allow sufficient time for the adhesive or resin to cure, following the recommended curing temperature and time.
Finishing and post-processing: After the curing process, trim or shape the CASCELL® FR foam as required for the final application. Use appropriate tools and techniques to achieve the desired surface finish and dimensions. Post-processing steps may include sanding, painting, or applying protective coatings.
