What’s different between Polyurethane foam, Polyether foam and Polyester foam?

Polyurethane(PU) foam mainly includes polyester foam and polyether foam, which can be sliced or rolled, and can also be processed by composite processing, hot pressing and blasting for open-cell structure according to customer requirements. PU foam is involved in various industries, including automobile industry, battery industry, cosmetics industry, bust underwear manufacturing industry, and furniture manufacturing industry due to its heat preservation, heat insulation, sound absorption, shock absorption, flame retardant, anti-static, and good air permeability.

Polyether foam has better water resistance, antibacterial resistance and low temperature impact resistance than Polyester foam, so polyether foam is ideal for aquarium and water treatment.

Polyester foam: In addition to the properties of polyether foam, it also has special properties such as oil resistance, abrasion resistance, corrosion resistance, high temperature resistance, and strong stretchability, and the product has uniform cells, good gloss, and composite adhesion to the fabric. Strong knot rate and other characteristics, widely used in high-end vehicle interiors, high-end fabric composite, flocking, cosmetics, printer consumables, filtration, and other fields. There is a simpler way to distinguish Polyether foam and Polyester foam: stretch the foam until it breaks. The polyester requires a lot more force and the elongation is greater than 150%.
