Polyurethane foam products are mainly used in automotive, construction and furniture industries to as the packing of its products or from the role of shock absorption and insulation. According to the different products, polyurethane foam products offer different features in some special applications. Used in the saddle, it can be rendered as soft and flexible, while for the insulating material can be rendered as hard and durable. 
 Industry challenge 
 In order to achieve the inherent characteristics of the polyol and isocyanate must be precise mixing ratio, so that the material react with each other to form a honeycomb structure. Through the addition of catalyst, air-dried agents, colorants and other additives, manufacturers can change or strengthen the physical properties of the foam product to achieve a particular purpose. 
 Polyurethane foam quality of the product depends on the mixing ratio of the polyol and isocyanate. Improper mixing ratio will result in uneven texture of the product of poor quality. 
 Another important factor is the variety of the viscosity of the polyol and isocyanate. Polyhydroxy compounds at room temperature, high viscosity, and may contain abrasive colorants. Its viscosity reduce the ease of transmission, multi-hydroxy compounds need to be heated or pass into the nitrogen pressure at the top of the feed tank. Isocyanates viscosity is usually higher than the polyol is lower, but easy to crystallize in the damp. Special shaft seal in the pump of domestic demand in order to prevent the occurrence of such situations. 
 Zenith, Pumps solutions 
 The pumps used in polyurethane foam technology are generally positive displacement gear pump, the pump conveying high viscosity fluids at high temperature and high pressure. This high-precision pump can accurately conveying the polyol and isocyanate, in order to ensure strict mixing ratio. Pumps Zenith, glue pump output steady, pulsating, hair foam production process can maintain a high degree of consistency in the pump using a special washing lips shaft seal to prevent the isocyanate in the shaft seal crystallization. 
 Zenith, the Pumps glue pump specifications and types can meet the needs of most of the polyurethane production process to ensure that the exact ingredients mixed in different process conditions. 
 How do you benefit 
 Accurate ingredients --- Zenith, Pumps glue pump output is accurate, no pulse and good repeatability, high degree of consistency to ensure that accurate ingredient in the production of polyurethane mixing and product quality. 
 Adaptable --- to make the proportion of ingredients with maximum adaptability, each pump should use a separate drive system. 
 Zenith, Pumps with proportional control system for two or more variable speed DC drives provide accurate process control. 
 To improve the quality --- Zenith, Pumps glue pump to ensure accurate mixing ratio, manufacturers of polyurethane products can greatly improve product quality through the use of Zenith Pumps adhesive pump.
