Polyurethane systems in the country
We put our science and technology competence to keep our customers COMPETITIVE, our environment SUSTAINABLE and to remain responsible to our SOCIETY.
Few products in the polymer world can compete with polyurethane in terms of the variety of applications and the range of properties that can be provided. Polyurethane, in terms of having various chemical structures, has enabled this possibility both in the synthesis and in the formulation of the final product. Razin Polyurethane Company, benefiting from its technical knowledge and high technological power, has targeted the production and supply of polyurethane systems in the main uses required by the country’s industries.
The highest performance of mechanical properties in different densities.
Our company's soft polyurethane systems and basic polyols play a distinctive role for all kinds of foam technologies, including viscoelastic foams, high elasticity foams, and microporous foams. Razin company produces materials for the mentioned applications in three main soft polyurethane production technologies, which include: Slapstick, Batch blocks and Molding. Our company also provides technical services in order to solve technical issues and to be able to meet the expectations of new markets.
Ultimate comfort, performance & economical solution
As a shoe sole manufacturer, you can count on Razin as leading technology solution provider of polyurethane material for the combination of mechanical properties, durability and optimum final density for your choice of material. Our team of expert engineers and innovative technologists provide you the best optimum solution for your shoe sole products in the variety of weight, product durability, mechanical properties and also colors.
Depending on their application, high mechanical properties and thermal insulation along with low weight are usually expected from hard foams, and in this regard, the cell type and foam structure play an important role in providing optimal performance.
Polyurethane systems consist of two components, one of which is a mixture of polyols with additives and the other a diisocyanate. When mixed homogeneously, they react forming polyurethane. The first of the components of the system is the mixture of polyols with reactive -OH groups, containing catalysts, flame retardants, expansive agents and foam stabilizing agents. The second component of the polyurethane system is the Isocyanate, a bond of one or several NCO groups. The most common would be the aromatic types (MDI, TDI, PMDI), but there are also aliphatic types.
The trust of our reliable costumers is the most business value for Razin. This is because of our belief in quality and the strict quality policy we have applied in all aspects of our production process, business strategies and management practices. This quality policy is based on the total quality management system and the procedures of ISO 9001: 2015.

We’ve targeted three key technology segments as our strategic innovation and technology plan, including; esterification, pre-polymerization and polyurethane system. Accordingly, we developed synthesis pilot plants, equipped our research center with state of the art facilities and got the valuable contribution of talented and creative technologists who are dedicated to polyurethane science.
Esterification is the process of combining an organic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water. This reaction occurs at high temperature and the presence of titanate base catalyst in the discontinuous esterification reactor.
Prepolymers are frequently used in injectable two-component systems to improve handling properties or reduce toxicity. Isocyanate-terminated prepolymers are prepared by reacting an excess of a polyisocyanate with a polyol at 60–۹۰ °C in the presence of a urethane catalyst, such as dibutyltin dilaurate. By varying the molar ratio of polyisocyanate:polyol, prepolymers with targeted NCO content and average molecular weight can be prepared. The NCO content of prepolymers typically ranges from 5 to 25 wt%, while less viscous quasiprepolymers typically have NCO content exceeding 25%

As our social responsibility, we provide our infrastructure, business brand, management system and investment capabilities to incubate technology startup companies willing to develop their ideas and develop the business based on their technology and innovation. We believe that our experience as developed technology company would help new startups to successfully manage their risks of failures.
We consider all aspects of our activities to understand how they interact with the environment in which we operate. As one of important basic fundamentals of our strategies; either our production process or the supply chain of our raw material should not negatively affect our environment but should significantly eliminate the concern of the use of plastic material in our society.
