PPI (pores per inch) indicates the number of cells in the foam per inch. The standard range is 10-80 PPI. PPI 10 has large cells and is completely open, while PPI 80 has small cells, is more …

Typical applications: vehicle and small engine air filters, water purification, air conditioning filters, speaker grills, microphone windscreens, cosmetic applicators, face mask filters, humidifier …

One of the most important characteristics that distinguish different types of reticulated foam are the pores per inch or PPI — ranging from 4 PPI up to 100 PPI. It’s important to understand …

Characteristics: A reticulated, open-pore, flexible, ether-type of polyurethane foam. Characterized by a skeletal structure of strands which provide a constant 97 percent void space and a very …

Filter foam is a porous, low-density, reticulated flexible polyester/polyether urethane sponge. With an open cell structure and three dimensional skeletal strand structure. Available in pore size …

60 PPI Filter Foam is the tightest filter foam that we offer. It has twice the number of cells per inch for filtration than the 30 PPI filter foam does. The finer or smaller the cells (pores), the more …

PPI (pores per inch) indicates the number of cells in the foam per inch. Standard range is 10ppi – 80ppi. PPI 10 has large cells and is completely open, while PPI 80 has small cells, is more …

Reticulated polyurethane foam is a very porous, open-cell, low-density polyurethane foam. This foam type undergoes a thermal reticulation process that removes the window cell membranes. …

Reticulated foams are available in a wide range of porosity, which is measured in PPI, or Pores Per (linear) Inch. There are two methods of reticula-tion: Thermal, and Chemical. U-Foam …

Mar 16, 2022 · Reticulated polyurethane is measured in pores per inch (PPI), which is the measure of how many “cells” or openings the foam has and it's used to determine its filtration …
