40mm 42mm PP Foam Pump Dispenser with Leak-proof Design for Hand Wash and Soap Spray

A PP plastic foam pump is a dispensing device made primarily of Polypropylene (PP) that transforms liquid into foam. It's the standard mechanism behind foaming hand soap, facial cleansers, and other personal care products.

What is it and How Does it Work?

Unlike regular pumps that dispense liquid, a foam pump mixes the liquid with air inside the pump head. When you press down, the mixture is forced through a fine mesh screen, creating light, airy foam. This provides a luxurious feel while using less product per pump

Key Material: Why Polypropylene (PP)?

Polypropylene is the preferred material for foam pumps because it offers:

• Chemical Resistance: Holds up well against soaps, lotions, and other cosmetic formulations

• Durability: Excellent fatigue resistance for repeated use

• Heat Tolerance: Suitable for hot fill applications up to 205°F (96°C)

• Recyclability: Fully recyclable, especially in all-plastic designs without metal springs

• Safety: FDA compliant and BPA free (BPA not intentionally added)
