PVDF (Polyvinylidene Fluoride)
Featuring incredibly high thermal and chemical resistance, PVDF can withstand temperatures up to 150°C while being chemically resistant. It is suitable for coatings and photovoltaic panels. It has good electrical insulation and is useful in the wire and cable industry, where thermal and electrical performance are essential.

Heat resistant PVDF gears
Heat resistant plastics are used in many capacities in many industries. They are used in high temperature conditions due to their light weight, high strength, and thermal efficiency. In aerospace, heat resistant plastics are often useful in parts that are subjected to high temperatures during flight or space missions. They are mainly used in engine components, thermal insulation, and structural sections where thermal stability and strength are preferred.

The application of these plastics in the automotive industry not only allows vehicles to withstand high heat, but also minimizes the mass of the car. This helps reduce fuel consumption and power, as the engines are smaller and lighter again. The high temperature resistance of consumer-rated plastics allows them to be used in many automotive engines and email dataset electrical parts. For example, PPS and PEI are essential in automotive engines, car hoods, transmissions, and sensors. They are heat and chemical resistant. They improve the durability and reliability of vehicles while supporting the trend towards weight reduction. The desired durability and reliability are the cause of fuel economy and low emissions.

Some plastics used in the electronics industry include heat-resistant plastics, since some parts of electronic products generate heat when in use. PPS, PES, and PVDF polymers are used in connectors, printed circuit boards, and insulating materials. These plastics now offer excellent electrical insulation and high-temperature resistance characteristics. They also enable electronic components to be encapsulated to protect them from thermal stress and ensure the stability of the devices under extreme conditions.

Manufacturing processes for heat-resistant plastics
Injection molding
Heat-resistant plastics are exceptional; to make them, specific steps must be followed to ensure that the products have the right qualities. Injection molding is a common application of heat stability in plastics processing. It involves liquefying the material and forcing it into a mold cavity at high pressure. It is essential for high-temperature plastics, including PEEK, PPS, and PEI.

It allows to create complex shapes with precise tolerances. However, the process requires temperature and pressure control in order not to disturb certain characteristics of the materials. It also confirms compliance with the mechanical and high temperature requirements of the final application through temperature and pressure control.
