Product Highlights

At room temperature it resists practically any type of chemical attack and at temperatures close to 70ºC, very few chemical agents can attack it. It is a plastic with a high degree of recyclability, with very little impact on the environment. To achieve greater hardness or resistance to abrasion wear, it is reinforced with a fiberglass filler.

Main Characteristics
  • Good stability against temperature.
  • Easy machining and low specific weight.
  • High chemical resistance.
  • High resistance to abrasion.
  • Excellent electrical insulator.
  • Minimal water absorption.
  • Great resistant to dilute acids, solvents and cleaning agents
  • Very tough
  • Easily weldable
