In ceramic fiber paper production, the sheet does not always fail at the forming stage. Sometimes the wet sheet looks acceptable, but problems appear later during drying, winding, or cutting. For example, the paper may feel weak after drying. The edge may crack during slitting. Fine fiber dust may come off the surface. In continuous production, these small problems can quickly lead to material los...

Waterborne polyurethane dispersions, commonly known as PUDs, may appear milky white, translucent, or slightly bluish in the liquid state. This difference is mainly related to particle size, particle size distribution, and how strongly the dispersed particles scatter visible light. In general, milky dispersions scatter more light, while finer dispersions allow more light to pass through. However, a...

Choosing a water-based resin should begin with the application, not with viscosity, solids content, or price. Products with similar technical data can behave very differently in production. A resin may work well on paper but show weak adhesion on plastic film. A coating may form properly under heated drying but remain tacky at room temperature. A low-viscosity polyurethane dispersion may look too ...

As global environmental regulations such as EU REACH and OEKO-TEX® Standard 100 become increasingly stringent, traditional solvent-based PU systems face growing restrictions in protective glove manufacturing. With advantages such as low VOC emissions and no DMFa residue, waterborne polyurethane (WPU) emulsions are rapidly becoming a key choice for glove manufacturers transitioning from solvent...

Printing problems on plastic film do not always come from the same part of the process. Ink may shrink immediately after transfer. A printed layer may look normal but fail a tape test after drying. Some problems only appear after water exposure, rubbing or when the press reaches normal production speed. During troubleshooting, it is useful to record when the defect first appears before changing se...

Poor surface smoothness, low gloss, and microscopic pinholes may occur during the spraying and baking of waterborne PTFE non-stick coatings. These defects can allow steam, fats, and corrosive substances to penetrate the coating over time, increasing the risk of blistering, peeling, and reduced non-stick performance. Why Pinholes May Form Pure PTFE has extremely high melt viscosity and limited flow...
