ETFE (Ethylene-tetrafluoroethylene)

  Related Performance of ETFE ETFE exhibits excellent toughness and wear resistance in a wide temperature range, and it combines high tensile strength, high impact strength, bending resistance and creep resistance, and combines the mechanical properties of hydrocarbon engineering polymers. Performance is combined with the chemical resistance and heat resistance of perfluoropolymers. ETFE has good friction and wear properties, which can be improved by adding fillers (such as glass fiber or bronze powder). Fillers can also improve creep resistance and increase softening temperature. Generally, the continuous upper limit of ETFE operating temperature is 150°C (302°F). When the polymer is crosslinked by peroxide or ionizing radiation, the physical strength can be maintained at a higher temperature. Highly crosslinked resins can withstand temperatures up to 240°C (464°F) in a short period of time. ETFE exhibits excellent dielectric properties, and its dielectric constant is very low, b...

Light Stabilizers: Safeguarding Polymers from UV Degradation

  In the world of polymers, the relentless assault of UV degradation is a perpetual challenge. UV radiation, whether originating from the sun or artificial sources, wreaks havoc on polymers, leading to compromised physical and chemical properties, discoloration, and a host of performance issues. It is in the face of these ever-present threats that light stabilizers  emerge as invaluable allies. Understanding UV Degradation of Polymers l  Weakened Mechanical Properties:  UV degradation precipitates the deterioration of the mechanical properties of polymers, leading to compromised strength, elasticity, and durability. l  Reduced Molecular Weight:  Exposure to UV radiation instigates the disruption of molecular chains within polymers, resulting in a reduction of molecular weight. This phenomenon undermines the structural integrity and performance of the affected polymers. l  Loss of Transparency:  Transparent polymers are particularly susceptible to ...
