AI Overview
Heat-resistant modifiers for PVC, such as Styrene-Maleic Anhydride (SMA) copolymers, acrylic-based modifiers (e.g., METABLEN H-602), and specialized N-phenylmaleimide terpolymers, significantly increase the Vicat softening temperature and thermal stability of PVC compounds. They prevent deformation in high-temperature applications like automotive parts, pipes, and electrical insulation.

What is PVC heat resistant?
The heat stability of raw PVC is very poor, so the addition of a heat stabilizer during the process is necessary in order to ensure the product's properties. Traditional product PVC has a maximum operating temperature around 60 °C (140 °F) when heat distortion begins to occur.
