C / Why is abrasive paper base sensitive to heat and humidity ?

After months spent getting your latest abrasive just right, you send off an urgent shipment to Scandinavia, braving the cold and all…and then wham, out of the blue, the customer calls you to say that he's disappointed and the product is too brittle.

Or maybe your sales team have landed a new contract in Asia? And you discover that your first delivery arrived in the middle of the monsoon season - with the edges of the abrasives all curled up.

Brittleness...Curling…Adhesion… Stiffness… Strength… sometimes resistivity…Are just some examples of the impacts of humidity and heat on coated abrasives.

 

Made mainly by cellulose, an abrasive paper backing is a material that reacts to external factors like climate. Temperature and humidity will have direct consequences on your maker adjustments and later on also on the perceived quality of your abrasive papers.

 

If you want to know:

  • Why does cellulose react with water and heat ?
  • How does it impact the characteristics of coated abrasives  ?
  • Where are the critical spots in the process [+ how to put them under control] ?
