The company’s professional knowledge combines a deep understanding of polymer chemistry, mechanical engineering, and operator adaptation, providing technical solutions precisely tailored to the customer.
Application Fields and Technologies
Spraying and dosing systems are designed for a wide range of industrial and engineering applications: — thermal insulation — spraying dedicated PU foam for residential homes, industrial buildings, cold storage, roofs, and cavities to achieve optimal thermal insulation. — acoustic insulation — spraying dedicated PU foam for noise reduction. — protective sealing and coating (polyurea) — application of advanced elastomeric membranes for sealing and protection against abrasion or impact; requires specialized high-temperature and high-pressure machinery. — piping and cold storage insulation — for site-pouring and injection in cold storage facilities and air conditioning systems. — gap filling — performing site-pouring, spraying, or a combination of both; includes floor lifting and filling for structural load support. — model and mold manufacturing — spraying dedicated materials with high hardness and strength for creating large and small prototypes and models.
Standardization and Environment
— Standard 921 — as part of the company’s professional activities to promote application quality in Israel, Polyurethane Ltd. led the 2016 revision of Israeli standard 921. This update enables the use of IN-series polyurethane systems for building insulation while meeting current safety and fire requirements. — green materials — the company leads the forefront of material innovation, ensuring systems comply with the latest European standards to prevent ozone depletion (e.g., materials with GWP < 10).
