Filtration

Application Description

Needle-punched nonwoven material is often used in filters. Rheology is an important property for the coating/binder as viscosity must allow good penetration and bond. Many filter applications also benefit from resistance to water as well as oil and other chemicals.

Rovene® 4021 is a good carboxylated styrene-butadiene latex for this type of application. Hydrophobic, and with some adhesion, it also provides a good combination of elasticity and strength.

Products
