In - depth Analysis of the Diverse Applications and Remarkable Effects of Guanidine Phosphate in the Polyurethane Industry

In the continuous development of the polyurethane industry, guanidine phosphate, as a highly valuable additive, is demonstrating excellent application effects in multiple sub - fields with its unique properties, playing a crucial role in enhancing product safety and functionality.

I. Polyurethane Foam: Building a Safe Fire - proof Barrier

Polyurethane foam is widely used in furniture, building insulation and other fields. However, its flammable nature has been a major safety hazard. This problem has been effectively addressed by adding guanidine phosphate during the production process. Take the polyurethane foam board used for building exterior wall insulation as an example. When guanidine phosphate is heated and decomposes, it rapidly forms a dense char layer on the surface of the foam. This char layer is like a solid fireproof wall, which can not only effectively isolate oxygen and heat but also capture the free radicals generated during the combustion process, thus significantly improving the flame - retardant performance of the foam. After adding guanidine phosphate, the polyurethane foam board can easily reach a higher fire - protection level, fully meeting the strict requirements of building fire - safety, providing strong protection for building safety.

II. Polyurethane Coatings: Building a Fire - proof Defense Line for Steel Structures

In places with extremely high fire - protection requirements such as industrial plants and warehouses, the fire - protection of steel structures is of vital importance. The polyurethane fire - proof coatings containing guanidine phosphate play a huge role here. When a fire breaks out, the guanidine phosphate in the coating quickly takes effect, prompting the coating to form a dense char layer. This char layer adheres tightly to the surface of the steel - structure substrate, like a solid armor, which can effectively slow down the heating rate of the steel structure at high temperatures and greatly extend the bearing time of the steel structure in the fire, buying precious time for personnel evacuation and fire fighting.

III. Polyurethane Elastomers: Enhancing Dual Guarantees of Flame Retardancy and Mechanical Properties

In the production of polyurethane elastomer products such as insulation sheaths for wires and cables and auto parts, the addition of guanidine phosphate brings a dual improvement in flame retardancy and mechanical strength. Take the polyurethane insulation sheath for wires and cables as an example. After adding guanidine phosphate, the sheath not only has excellent flame - retardant performance, effectively preventing the spread of fire along the cable in case of a fire, but also significantly enhances its mechanical strength, being able to withstand a certain degree of external pulling force. This ensures that the insulation sheath of wires and cables can work stably in various complex environments, strongly guaranteeing the safe use of wires and cables and reducing the risk of safety accidents caused by line problems.
