The material of the beauty sponge is neither latex nor the common sponge we use, but polyurethane, which is non-allergenic, non-shedding, and more durable. Let's learn about the secret of the beauty sponge - Wanhua Chemical TDI hydrophilic polyurethane prepolymer!
Product Specific Application
Product Supplier Name
Wanhua Chemical WanSponge GST
Main Applications
WanSponge GST is a TDI-based hydrophilic polyurethane prepolymer that can be used to make hydrophilic foams, such as beauty sponges, bath sponges and kitchen sponges. WanSponge GST can react with liquid formulas containing surfactants and fillers according to application requirements to prepare foams with pore diameters of 50-500 μm. The pore size, feel and resilience can be further adjusted by adjusting process parameters and water-based formulas.

Product Question Time
QWhat
is the difference between latex beauty eggs and non-latex hydrophilic polyurethane beauty eggs?
ALatex
beauty eggs: they fall off, have odor, and have a high allergy rate.
Non-latex hydrophilic polyurethane beauty egg: no residue, no odor, fine density, easy to clean, skin-friendly and hydrophilic.
QHow
to adjust the properties of hydrophilic polyurethane foam products?
A
① Adjustment of cell fineness:
Appropriately increase the amount of closed-cell agent added/appropriately increase the head speed/appropriately increase the prepolymer content/appropriately increase the amount of emulsifier added.
②Elastic adjustment:
Increase the amount of cell opening agent while increasing the amount of cell closing agent.
③The finished product's skin peels off:
Increase the prepolymer content.
