Vuller

Vuller is a Dutch noun meaning a filler or material used to fill gaps or to add volume. The word derives from the verb vullen, “to fill,” with the agent-noun suffix -er. The sense is broad and covers materials used to occupy space, smooth irregularities, or modify a composite’s properties.

In construction and DIY, vullers include putty, spackle, plaster, and similar compounds used to fill holes, seams, or cracks and to create a smooth surface before painting or wallpapering. In manufacturing and materials science, the term refers to filler materials added to polymers, rubbers, ceramics, or composites to modify properties, improve processing, or reduce cost. Common industrial fillers include mineral powders such as calcium carbonate, talc, and silica, among others.

In cosmetics and medicine, fillers are substances used to restore volume, fill wrinkles, or augment soft tissue. In Dutch-language medical and cosmetic literature, these products are described in terms that align with the general concept of vulling or vullers, referring to the role of adding material to achieve a desired appearance or function.

The word also occurs as a surname in some cases, indicating possible historical association with occupations involving packing or filling.
