Multi-purpose solutions for thermal insulation, volume filling, model manufacturing, and buoyancy — thermal insulation: the forefront of thermal and economic savings through the use of state-of-the-art technology. — structural strength: exceptional strength-to-weight ratio and high adhesion capacity to various substrates. — water resistance: closed-cell structure ensures excellent resistance to water absorption and low weight providing buoyancy. — versatility: wide application across a vast array of products — from refrigerators to machining boards.
The IN series includes rigid polyurethane systems representing the forefront of thermal insulation applications through state-of-the-art technology. The systems are characterized by an exceptional insulation coefficient (Lambda 0.022), an outstanding strength-to-weight ratio, high adhesion capacity to various substrates, and excellent resistance to water absorption—all while meeting strict environmental standards (GWP < 10). These materials are widely used globally across a vast array of applications and products, particularly where energy efficiency is a core consideration (e.g., household and industrial refrigerators).
Application Fields and Engineering Solutions
— thermal insulation and energy savings — these foams have the best thermal insulation capacity in the industry, significantly outperforming other options (except vacuum). The foam is exceptionally durable and maintains its properties over decades. Systems are matched for spraying or pouring to create a continuous insulation shell. Advanced raw materials, R&D, and decades of experience have resulted in foams with improved high-temperature resistance and fire retardancy complying with the strictest building standards—while meeting environmental requirements, specifically ozone layer protection and low GWP. — structural filling and element strengthening — thanks to the expansion and adhesion capacity of the foam during the rapid polymerization process, it is used as a filling/strengthening material for various structures and products. It provides structural rigidity to lightweight elements, eliminates the need for external adhesives, and fills complex cavities in a single, simple application. — marine applications and buoyancy — with a closed-cell rate exceeding 92%, these systems ensure reliable buoyancy over time. The material is resistant to the absorption of water, fuels, and oils, and is used for filling boat hulls, buoys, and industrial buoyancy devices. — rigid boards and machining — we provide rigid polyurethane boards in varying bulk densities, designed for precise machining. The boards feature a homogeneous structure allowing for easy and simple milling of fine details. They can be painted and processed using various methods. Particularly suitable for the manufacturing of engineering models, casting molds, decorative elements, and large-scale sets.
Application Methods
— professional spraying — using high-pressure two-component equipment for architectural and industrial applications. — pouring/casting — filling molds, products, or existing cavities in continuous or discrete processes. — ready-for-use boards — cutting to project dimensions for use as floor insulation, truck bodies, and containers.
