Frequently Asked Questions

What is PPI in foam?

PPI stands for "Pores Per Inch" — it measures the number of open cells per linear inch. Higher PPI means finer filtration but lower airflow.

Can reticulated foam be used in aquariums?

Yes, reticulated foam is widely used in aquariums as a biochemical filter medium to support beneficial bacteria growth.

What's the difference between activated carbon foam and photocatalyst foam?

Activated carbon foam adsorbs pollutants, while photocatalyst foam (with TiO2) breaks them down using light, offering self-cleaning and long-term purification.

Do you offer custom shapes and sizes?

Yes, we provide full customization including die-cutting, CNC shaping, and molding for any industrial or consumer application.

Is cellulose sponge biodegradable?

Yes, cellulose sponge is made from natural wood pulp and is fully biodegradable and eco-friendly.
