why Abrasive disc back must use good quality vulcanized fiber ?

Abrasive disc  are used in various industrial applications such as grinding, sanding, and polishing. The back of the abrasive disc plays a critical role in ensuring that the disc stays securely attached to power tools during use.
Using good quality vulcanized fiber for the backing material is essential for several reasons:
  1. Durability: Vulcanized fiber has excellent strength and toughness compared to other materials like plastic or paper, making it ideal for withstanding high-speed rotation without tearing apart.
  2. Resistance against Heat : High temperatures can cause plastics & other materials to melt , warp or even catch fire when exposed prolonged periods of time unlike vulcanised fibre which can withstand heat up to certain temperatures
3 . Moisture Resistance: Being moisture-resistant means that vulcanised Fibre does not absorb water easily which could lead swelling over time thereby causing distortion
4 . Porosity : The porosity of vulcanized fiber ensures effective dust extraction from abrasive work surfaces .
5 . Compatibility – Vulcanised Fibre is compatible with most resin bonding agents used in manufacturing abrasive product meaning there’s less likelihood adhesive failure during operation

Safety – Since abrasives operate at relatively high speeds ,the presence any defects within backing material could lead catastrophic consequences if breakage occurs while machine is still running leading injury/damage etc..

Overall,vulcanized fiber offers outstanding performance characteristics including high dielectric strength,resistance against heat ,moisture,and most chemicals.Its unique combination physical attributes allows it find use across many industries from automotive manufacturing through electronics production right up sports equipment manufacture making it one more widely applied materials around today especially where safety & durability are major concerns.
The data for vulcanized fiber used as backing material for abrasive discs can vary depending on the specific application requirements. However, some general data that may be considered include:
  1. Thickness: Vulcanized fiber is available in a range of thicknesses from 0.5mm to 1.5mm or even higher based on customer specifications.
  2. Color: The color of vulcanized fiber typically varies between brown and black.
  3. Density: The density of vulcanized fiber ranges from about 1 g/cm³ to over 1.2 g/cm³, which provides good stability and strength required for abrasive applications.
4.Tensile Strength :Vulcanised Fibre has high tensile strength ranging from approximately 80-150 Mpa making it suitable withstanding the forces generated during operation
5 . Temperature Range : Vulcanised Fibre can withstand temperatures up to approximately +115°C before begining to lose its mechanical properties
6.Moisture Absorption – Since moisture absorption affects dimensional stability,vulcanised fibre typically has maximum moisture absorption rates below around 10% by weight .
7.Porosity – Porous structure ensures effective dust extraction while maintaining structural integrity throughout use
It’s important to note that these specifications are not exhaustive but rather provide an overview of the typical characteristics of vulcanized fiber used in abrasive disc backing .If you have any specific requirements, it would be best to consult with your manufacturer or supplier who could advise accordingly when making abrasive disc backing

Vulcanized fiber is paper a good insulator.

Vulcanized fiber is paper a good insulator.

Yes, vulcanized fiber, or fish paper, is an excellent insulator. This is due to its unique properties, which make it ideal for use in a wide range of electrical applications.
One of the key properties of vulcanized fiber that makes it such a good insulator is its high dielectric strength. This refers to the material’s ability to withstand high voltages without breaking down or conducting electricity. Vulcanized fiber has a dielectric strength that is several times higher than that of regular paper, which makes it ideal for use in electrical insulation applications.
Another important property of vulcanized fiber is its high heat resistance. This material is able to withstand temperatures of up to 150°C without degrading or losing its insulating properties. This makes it ideal for use in high-temperature applications, such as electrical motors and transformers.
In addition to its electrical and thermal properties, vulcanized fiber is also highly resistant to chemicals and moisture. This makes it an ideal material for use in harsh industrial environments, where exposure to chemicals and other contaminants can cause other materials to break down and lose their insulating properties.
Overall, vulcanized fiber is an excellent choice for use as an electrical insulator. Its unique combination of properties makes it ideal for use in a wide range of industrial and consumer applications, and its high performance and durability make it a popular choice among engineers and designers alike.
