Thiolyte is a brand named electrical insulating thermoset phenolic laminate material.

Overview

These industrial thermoset laminates are generally stronger than thermoplastic materials at elevated temperatures up to 130 °C (266 °F). Thermoset materials cannot be easily recycled since they cannot be melted and re-moulded after curing like thermoplastics.

A hard, dense engineering plastic manufactured by applying heat and pressure to layers of resin-impregnated paper sheet or cotton fabric. During the heat and pressure process polymerization occurs and this transforms the layers into a high-pressure thermoset laminate.

Sheets of material measuring up to 8000 mm long can be produced however most popular sheet size demand is for 1220 mm x 1220 mm and 2440 mm x 1220 mm. The available thickness range is from 0.4 mm to 100 mm with greater thickness material availability up to 160 mm (material type dependent) on request. A range of different Thiolyte grades are available depending on the specific electrical / mechanical performance requirements.

Epoxy resin, silicone resin, melamine resin and modified polymer–based materials with paper, cotton fabric, glass fabric, carbon fibre and other reinforcements are also produced from Stage-B "pre-preg" laminate core material.

Contract production of high-tech composite laminates, honeycomb composite laminates and a range of decorative laminates to the required specification levels are available.

Grading

  • Paper based Phenolic laminates conforming to NEMA grades X, XX, XXX and XXXPC.
  • Cotton based Phenolic laminates (canvas and linen) conforming to NEMA grades C/CE and L/LE.
  • Glass based laminates of Epoxy (NEMA G10 and NEMA G11), Melamine (NEMA G5) and Silicone (NEMA G7).
  • Graphite Impregnated Cotton based Phenolic laminates to suit end-user requirements.

    • Standards

    Thiolyte Phenolic Laminates conform to the following standards:

  • British Standards (BS)
  • German Standards (DIN)
  • European Standards (IEC)
