Scratch resistance testing of hard-to-scratch transparent resin in the laboratory. Multiple sample plates and testing equipment are lined up.

Selection of transparent resin with few scratches｜Thorough comparison of the types and characteristics of machine covers

2026/1/21    Cover, Resin

  Here, we make a note of "Examination of transparent resin that is hard to scratch and peripheral information" about transparent resin used in machine covers. When designing the safety cover of the machine and the view window of the cleaning equipment, it is specified in the drawings."..
