Cascell® IH rigid foams are typically produced through a chemical foaming process using polyurethane (PU) or polyisocyanurate (PIR) as the base material. The primary manufacturing methods used to produce Cascell® IH rigid foams include:
Polymerization and Blending: The process begins by combining the base polymer (PU or PIR) with various additives and chemical agents. These additives can include catalysts, blowing agents, flame retardants, and stabilizers.
Mixing: The blended mixture is then thoroughly mixed to ensure uniform distribution of additives and achieve the desired chemical reaction.
Foaming: The key step in the manufacturing process involves the introduction of a blowing agent, typically a low-boiling-point chemical compound, into the mixture. This blowing agent decomposes or vaporizes when exposed to heat, releasing gas bubbles throughout the material and causing it to expand.
Molding: The foamed mixture is then poured or injected into molds of the desired shape and size. These molds can be customized to meet specific product requirements.
Curing: The filled molds are then subjected to a controlled curing process, which involves heating the material to a specific temperature. During curing, the chemical reaction between the base polymer and the blowing agent continues, resulting in the formation of a rigid foam structure.
Cooling and Demolding: After curing, the foam is allowed to cool, and the rigid foam product is removed from the molds. The cooling process helps set the foam's final shape and structure.
Cutting and Trimming: The foam blocks or sheets may undergo additional cutting and trimming processes to achieve the desired dimensions and surface finish.
Quality Control: Quality control measures are implemented throughout the manufacturing process to ensure that the final Cascell® IH rigid foam products meet the required specifications and performance standards.
It's important to note that the specific formulations, additives, curing parameters, and molding techniques can vary based on the desired characteristics and applications of the Cascell® IH foam. These manufacturing methods are chosen to produce rigid foams with excellent thermal insulation properties, low thermal conductivity, high compressive strength, and flame retardancy, making them suitable for various industries and applications, such as construction, transportation, and industrial insulation.
