Advantages of Polyester Unsaturated Resin
Normal temperature and pressure forming: unsaturated polyester resincan be cured at room temperature and formed at normal pressure, without complicated high-temperature and high-pressure equipment and special processing conditions.
High process flexibility: can be processed through a variety of molding processes, such as hand paste, laminating, spraying, molding and so on.
Moderate mechanical properties: cured unsaturated polyester resin with high strength, including tensile strength, bending strength and compression strength, can meet the needs of a variety of applications.
Excellent electrical insulation performance: with good electrical insulation performance, can be used to manufacture electrical equipment insulation components, such as motor winding insulation, transformer insulation shell, etc. .
Good corrosion resistance: to water, dilute acid, dilute alkali and so has a certain corrosion resistance
The variety of products is rich and the adaptability is extensive: the raw material of unsaturated polyester resin is various, through the different raw material combination and the formula design, can produce each kind of performance, the different use product, to meet the needs of different industries and areas.
