Hot melt adhesive testing instrument scheme for sanitary napkins [in line with HG/T 3948]

Hot melt adhesive is used in the positioning of sanitary napkins. As sanitary products, the requirements for its indicators are naturally very high. The HG/T3948 standard specifies the requirements for hot-melt adhesives used for positioning of sanitary napkins and sanitary pads, including test methods and inspection rules.

The experimental methods of hot melt adhesives for sanitary napkins include visual inspection of appearance, measurement of melt viscosity, thermal stability, 180° peel strength before aging, 180° peel strength after aging, hygienic requirements, transferability, etc.

According to the hot melt adhesive test method stipulated in the standard, Xiaochao searched in our mall and compiled a list of instruments suitable for this standard test for reference by all industry friends. Please refer to:
