BCP-1631 | Medium voltage Busbar Coating Powder

Main features
  • 49 kv/mm breakdown voltage
  • Specifically formulated for steel
  • Thermoplastic Polymer Alloy

Product Description

Linqsol BCP-1631 is a self-adhesive thermoplastic coating powder capable of achieving a breakdown voltage of up to 49 kV/mm. It is a semi-crystalline powder that exhibits a high melt flow and low melt temperature, which is ideal for the high-speed coating of thin and complex parts.

A distinctive feature of Linqsol BCP-1631 is that it has a virtually infinite shelf life when stored at room temperature since cross-linking is unnecessary for coating. It is very easy to apply, environmentally friendly, and great for applications where cold impact resistance of up to -30C is required.

This thermoplastic is used in technical and functional applications and offers excellent flexibility, elongation, and resistance to stress cracking. Some application ideas are copper busbars, valves, and fittings, industrial springs, rail guards, cable trays, etc. 


Advantages of BCP-1631

  • Excellent adhesion and elongation
  • Good moisture barrier
  • Excellent cold impact
  • Good chemical resistance

Breakdown Voltage
Breakdown Voltage
Breakdown voltage is the minimum voltage necessary to force an insulator to conduct some amount of electricity.
It is the point at which a material ceases to be an insulator and becomes a resistor that  conducts electricity at some proportion of the total current. 

After dielectric breakdown, the material may or may not behave as an insulator any more because of the molecular structure alteration. The current flow tend to create a localised puncture that totally alters the dielectric properties of the material.

This electrical property is thickness dependent and is the maximum amount of voltage that a dielectric material can withstand before breaking down. The breakdown voltage is calculated by multiplying the dielectric strength of the material times the thickness of the film.

Mechanical Properties
Hardness is a dimensionless quantity. There is no direct relationship between measurements in one scale and their equivalent in another scale or another hardness test.
Durometer (Shore D) 50
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
