PAPER BASED
Presspahn/Elephantide

Developed for the transformer industry paper based insulation is excellent at providing cost effective insulation either in air or oil. Also know in the trade as Presspahn or Elephantide.

Also used in the printing industry as Make Ready Board.

 
A flame retardant (UL Approved) plastic material suitable for multiple electrical applications.
 
These products have characteristics which make them ideally suited for electrical applications.
   

SRBP
Synthetic Resin Bonded Paper

(Paxoline / Pertinax)

Also known as Paxoline, Pertinax

Available in a variety of grades from commercial to high spec in sheet, rod and tube. Its applications can vary from backing and entry drilling boards to high voltage electrical insulators.

Specifications: P1 (Standard Grade) / P3 (High Quality Grade)

 

SRBF
Synthetic Resin Bonded Fabric

Most commonly used in mechanical applications (gears, bearings, jigs and fixtures). It is available in a variety of grades with slightly different characteristics.

Specifications: F1 (Fine Weave) / F2 (Medium Weave) - PDF Format

 
Epoxy FR4
Glass-epoxy laminates are specified for their extremely high strength and high dimensional stability over temperature. They can be used for terminal boards, in high humidity applications, electrical and electronic test equipment and electric rotor insulation. Presspahns range of CNC machines allow precision cutting of these materials to customers requirements.
 

Polyester Glass

Produced by combining polyester resin with glass mat and suitable inorganic fillers laminated under heat and pressure. These laminates have excellent mechanical and electrical properties and include special grades imparting flame resistance and arc and track resistance. The also exhibit food retention properties and dimensional stability at elevated temperatures.

Specification: GP03

 
Known as Hostaphan the films are made of poly(ethylene terephthalate), PET, and characterised by outstanding physical data. They are biaxially oriented and heat-set. These films are suited to a diverse range of uses, due to their excellent properties.
 
Polytetrafluroethylene (PTFE) is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products for applications excluded to other materials.
     
 

Elmtherm board is made from a micro porous material that allows it to have the lowest thermal conductivity of any industrial insulating product.
Capable of withstanding termeratures of up to 1000°C it is ideally suited for use in the metal melting industry or any application where exceptional levels of thermal insulation are required.

 
 
 

Vulcanised Fibre Sheet

Vulcanized Fibre is a hard, durable, chemically pure cellulose product that contains no resin or bonding agents. Vulcanized Fibre is manufactured in Rolls, Coils, Sheets, Tubes and Rods. The electrical grade of Vulcanized Fibre is sometimes referred to as Fish Paper.
