Uniform film formation is essential for glove strength, appearance, and barrier performance. In NBR dipping systems, film quality depends not only on latex properties but also on formulation design.
Viscosity, particle size distribution, and surface tension all influence latex pickup and drainage behavior on the former. Instabilities in any of these parameters can result in thin spots, pinholes, or uneven thickness.
Additives such as wetting agents, defoamers, and stabilizers must be carefully selected to avoid disrupting latex stability. Nonionic additives are generally preferred due to their lower impact on ionic balance.
Formulation optimization should always be validated under real dipping conditions, including circulation time and contamination buildup. Laboratory film tests alone cannot fully predict production performance.
