01.

F621 (GPO-1) polyester glass mat products

Mechanical properties: Glass fiber polyester felt has extremely high tensile strength, which can provide strong support when the material is subjected to internal and external pressure. This not only improves the bearing capacity of the material, but also extends its service life.


Tear resistance: Even in harsh environments, polyester felt is not easy to tear, ensuring long-term stable use. This is very important for applications that need to withstand large external forces or complex stress conditions.


Acid and alkali resistance: Glass fiber polyester mat has good tolerance to chemicals such as acids and alkalis, and is suitable for various corrosive environments. This not only extends the service life of the material, but also reduces maintenance costs.


UV resistance: It has good tolerance to UV rays and can maintain stable performance under long-term exposure to sunlight. This is especially important for materials used outdoors.

Lightweight: Fiberglass polyester mat is lighter than traditional metal materials and is easy to transport and install. This is especially important for large-scale engineering projects, which can significantly reduce the difficulty and cost of construction.


High strength: Despite its light weight, fiberglass polyester felt has extremely high strength and can maintain stability and durability when subjected to large external forces.


Low thermal conductivity: Fiberglass polyester mat has a low thermal conductivity, which can effectively prevent heat transfer and reduce energy loss. This is especially important for high-temperature or low-temperature materials, which can significantly improve energy efficiency.


High temperature resistance: Many types of fiberglass polyester felt can withstand temperatures up to 650°C or even higher, suitable for applications in extreme environments.

FAQ

 

Q: What are the main types of polyester resins used in molded products?

A: There are two main types - thermosetting polyester resins and thermoplastic polyester resins. Thermosetting polyesters, once cured, cannot be remelted. They are often used in applications where high heat resistance and rigidity are required. Thermoplastic polyesters, on the other hand, can be melted and re - molded multiple times. Examples include polyethylene terephthalate (PET) and polybutylene terephthalate (PBT).

Q: How are polyester molded products made through injection molding?

A: First, the polyester resin (either thermoplastic or a pre - mixed thermosetting resin with any required additives) is melted in an injection molding machine's barrel. Then, it is injected under high pressure into a mold cavity. The mold is cooled (for thermoplastic polyester) or cured (for thermosetting polyester) until the resin solidifies into the shape of the mold cavity. Finally, the molded part is ejected from the mold.

Q: How is the quality of the molded product ensured during manufacturing?

A: Quality is ensured through several methods. Firstly, the raw materials are carefully selected and tested for purity and consistency. During the molding process, parameters such as temperature, pressure, and time are closely monitored and controlled. Mold design is also crucial; a well - designed mold ensures proper filling, uniform thickness, and minimal defects. Post - molding inspection includes visual inspection for surface defects, dimensional checks using precision measuring tools, and sometimes non - destructive testing such as ultrasonic inspection to detect internal flaws.

Q: What is the typical density of polyester molded products?

A: The density of polyester molded products varies depending on the type of polyester resin and any reinforcements. For example, pure thermoplastic polyester resins like PET have a density of around 1.3 - 1.4 g/cm³. When reinforced with glass fibers, the density can increase to around 1.5 - 2.0 g/cm³, depending on the fiber content.

Q: How strong are polyester molded products?

A: The strength of polyester molded products can vary widely. Unreinforced thermoplastic polyesters have moderate tensile strength, typically in the range of 50 - 70 MPa. However, when reinforced with glass fibers, the tensile strength can increase significantly, reaching up to 150 - 250 MPa or more, depending on the fiber loading and orientation.

Q: What is their flexural modulus?

A: The flexural modulus of polyester molded products also depends on factors like resin type and reinforcement. Unreinforced thermoplastic polyesters may have a flexural modulus in the range of 2 - 3 GPa. With glass fiber reinforcement, the flexural modulus can be in the range of 5 - 10 GPa or higher.
