What is 60 ppi foam?

What is 60 ppi foam?

For example, 10 PPI foam has large pores, approximately 0.10” in diameter and offers very little resistance to airflow. Consequently, it is not very effective at capturing small particles and arrestance values are typically below 50%. By comparison, 60 PPI foam, has small pores, approximately 0.015” diameter.

What is poret foam?

Poret ® foam is a viscoelastic polyether foam with outstanding resistance to acids, bases, hydrolysis, and other forms of chemical attack often encountered in aqueous environments such as aquariums, sumps, or ponds. The specially engineered reticulation process creates foam with ~97% defined pore size.

How long does poret foam last?

Long life, 5-10 years and more! High compression strength to prevent shrinking. Hydrophilic surface facilitates colonization by beneficial microorganisms.

Is LDPE foam?

Polyethylene is a closed cell foam, also referred to as a PE foam or LDPE foam. The material starts off as a thermoplastic which is then blown into a foam format. This is a highly durable as well as versatile product.

What is the difference between 45 PPI and 30 PPI foam?

30 PPI Filter Foam has larger cells than 45 or 60 PPI foam. This allows for more air to pass through. 1″ Reticulated Foam, 30 PPI 48″ X 108″, 4 sheets.

What is reticulated foam sheets?

Reticulated Polyurethane Foam Sheet 1 Reticulated – cell walls are removed to increase the porosity of the foam 2 The porosity of foam listed in PPI (Pores Per Inch) 3 20 & 30 PPI are ether-based, all others are ester-based for filters only More

Can reticulated foam act as a filter?

Reticulated foam can act as a filter. Filter foam is a reticulated polyurethane foam, specially adapted to air and liquid filtration, in a range of controlled cells from 10 pores per inch to 100 PPI.

Is reticulated foam a good sound attenuator?

A coarse porosity, 10 PPI, reticulated foam is effective as a sound attenuator, scrubber pad, washable filtration media for air conditioners, furnaces, small engines and automobile air cleaners, plus many other applications. Reticulated foam can act as a filter.
