Glass-fibre reinforced polyamide (GRP)<\/h3>\n\n\n
\n\n \n
\n \n \n

Glass-fibre reinforced polyamide (GRP) is a material that combines the properties of polyamide with the benefits of glass fibre reinforcement. Here are some of the typical properties of GRP:<\/p>\n <\/div>\n \n <\/div>\n\n <\/section>\n\n\n

\n
\n \n
    \n
  • \n \"\"\n

    Excellent mechanical resistance<\/h4>

    Glass-fibre reinforcement gives polyamide superior mechanical strength, particularly in terms of impact and abrasion resistance, tensile strength, flexural strength and compressive strength. Industrial socket outlets can be exposed to harsh working conditions. GRP is a robust material suitable for a wide range of applications, reducing replacement and maintenance costs over the long term.<\/p>\n<\/div>\n <\/li>\n

  • \n \"\"\n

    Lightweight<\/h4>

    Although GRP is very resistant, it remains relatively light compared to other materials, making it easier to install and handle industrial plug socket-outlets for applications requiring both strength and lightness.<\/p>\n<\/div>\n <\/li>\n

  • \n \"\"\n

    Corrosion resistance<\/h4>

    GRP is naturally resistant to corrosion, making it a wise choice in corrosive or humid environments where other materials may deteriorate more quickly.<\/p>\n<\/div>\n <\/li>\n

  • \n \"\"\n

    High levels of electrical insulation<\/h4>

    Good electrical insulation is essential for user safety and protection against short circuits.<\/p>\n<\/div>\n <\/li>\n

  • \n \"\"\n

    Resistance to extreme temperatures<\/h4>

    GRP can withstand both low and high temperatures, allowing it to be used in environments ranging from [-40\u00b0C to +60\u00b0C] without any special precautions. GRP also has a low coefficient of thermal expansion, which means it retains its shape and dimensions over a wide range of temperatures.<\/p>\n<\/div>\n <\/li>\n

  • \n \"\"\n

    UV resistance (f1)<\/h4>

    If industrial plug socket-outlets are used outdoors or in environments exposed to UV rays, it is important that the material is resistant to degradation caused by prolonged exposure to sunlight.
    \nGRP retains its mechanical properties and colour even under prolonged UV exposure, making it ideal for outdoor use.<\/p>\n<\/div>\n <\/li>\n

  • \n \"\"\n

    Chemical resistance<\/h4>

    In certain industrial environments, plug socket-outlets may be exposed to aggressive chemicals and cleaning agents. GRP is resistant to many chemicals, making it an appropriate choice for these applications.<\/p>\n<\/div>\n <\/li>\n

  • \n \"\"\n

    Ease of manufacture<\/h4>

    GRP can be moulded into a variety of complex shapes, allowing the industrial plug socket-outlets to meet the specific needs of each application.<\/p>\n<\/div>\n <\/li>\n <\/ul>\n <\/div>\n<\/section>\n\n\n

    \n\n \n
    \n \n \n

    These properties make glass fibre reinforced polyamide a robust and versatile choice for industrial plug and socket-outlets, offering strength, longevity, and electrical safety.<\/p>\n <\/div>\n \n <\/div>\n\n <\/section>\n\n\n\n

    Zamak<\/h3>\n\n\n
    \n\n \n
    \n \n \n
    \n

    Zamak is an alloy of zinc, aluminium, magnesium and copper. Zamak has a relatively low melting point compared with other metals and is easy to machine, which facilitates the manufacturing process and allows complex shapes to be produced with extremely fine details and thicknesses. The surface appearance depends on the moulding and the finish: rough, paint, or coated against corrosion.<\/p>\n <\/div>\n \n <\/div>\n\n <\/section>\n\n\n

    \n

      \n
    • \n \"\"\n

      Excellent mechanical resistance<\/h4>

      Zamak offers great mechanical strength, which is crucial for industrial plug socket-outlets that may be subjected to significant stress during use. Good tensile strength, impact resistance and wear resistance. Good damping capacity. Good dimensional stability.<\/p>\n<\/div>\n <\/li>\n

    • \n \"\"\n

      Corrosion resistance<\/h4>

      Thanks to its chemical composition, Zamak is resistant to corrosion and ensures the durability of industrial plug socket-outlets, especially in environments where they may be exposed to humidity or corrosive chemicals.<\/p>\n<\/div>\n <\/li>\n

    • \n \"\"\n

      Environment<\/h4>

      Good resistance to petrol, alcohols, oils and mineral lubricants. Can withstand temperatures up to 200\u00b0C.<\/p>\n<\/div>\n <\/li>\n <\/ul>\n <\/div>\n<\/section>\n\n\n

      \n\n \n

      \n

      Aluminium is a material that allows great freedom in the design of parts, combining lightness, strength and resistance in all operating environments. The surface appearance depends on the casting and finish: anodising, paint, etc.<\/p>\n <\/div>\n \n <\/div>\n\n <\/section>\n\n\n
