Polyurethane material for top car materials
According to the latest statistics, as of August 2015, the domestic production capacity of polyurethane raw material MDI (diphenylmethane diisocyanate) has soared to 3.02 million tons per year. The consumption of polyurethane materials for automobiles is in a stage of rising.
The increase in polyurethane consumption is inseparable from the increase in sales in the global automobile industry. According to incomplete statistics, my country's automobile sales reached 23,491,900 in 2014, a year-on-year increase of 6.86%. In the plastics used in modern automobile materials, the amount of polyurethane is not only the largest, but also its application range is unparalleled, from the car box to the outer parts, from soft to hard, from light to dense, all the way to high High-strength glass fiber reinforced products, polyurethane applications can be seen everywhere.
The polyurethane material for automobile roof is the most demanding among all polyurethane materials for vehicles, especially now it needs to be combined with a duct folding machine to meet the hardness and rigidity requirements of the substrate during the hemming process of the duct folding machine.
o provide the security industry with important information such as development scale, speed, industrial concentration, product structure, ownership structure, regional structure, product prices, benefit status, etc., and for the security industry to study and predict the development trend of securit
1. Site selection skills The location of the thermal insulation house of the breeding farm should be a place with a leeward wind and sunny, high terrain and dry soil. 2. Alternative insulation materials for the insulation room of the farmExtruded polystyrene foam (extruded board), molded polystyr
What are the classifications of high-pressure mixing spraying machinery for thermal insulation materials1. The important role of the on-site polyurethane high-pressure mixed foam external wall insulation systemPolyurethane rigid foam external wall insulation system is a kind of external wall insulat
is mostly used in building boards and insulation walls, mainly for heat preservation and waterproofing. The equipment used to complete the polyurethane foaming process is a polyurethane high-pressure foaming machine.The overall layout of the polyurethane foaming machine fully considers the use of sp
For many new products and technologies, only those that have passed theoretical and practical tests are worth recommending. The same is true for polyurethane products. It is recommended that you weigh the relationship between price and value when purchasing polyurethane products. The self-discipline
Polyurea as a new type of environmentally friendly spraying Compared with traditional environmentally friendly coating technology, spraying polyurea elastomer technology has the following advantages:1. It does not contain catalyst, it cures quickly, and can be sprayed on any curved surface, inclined
Polyurethane rigid foam is a material with a large amount of flexible deformation. It has strong resistance to external deformation. It is not prone to cracks under the action of external force, temperature deformation, dry and wet deformation, etc., effectively ensuring the stability and durability
In recent years, China has made innovations in wall insulation materials, especially civil engineering exterior wall insulation systems, exterior wall decoration fire protection systems, etc., and proposed the combination and selection of high-performance insulation materials, but they have achieved
Excellent performance characteristics of polyurethane elastomer: We are a manufacturer mainly engaged in the research, development and production of castable polyurethane elastomer products. Because of the best comprehensive performance, the output of castable polyurethane accounts for more than 60
If it is idle for more than 1 month, the polyurethane foaming opportunity will be blocked and your equipment will be paralyzed. The isocyanate component in the black material system of the polyurethane foaming machine will crystallize if it does not flow for a long time. So what we have to do is to
