What Is Polyurethane Soaped Sponge?

May. 08, 2018

The polyurethane soaped sponge is a low-density PU with a foam density of less than 18 kg/m3, usually with a water consumption of more than 4.5 parts (per 100 parts of polyol) and a TDI content of more than 55 parts. The problem of foam heat dissipation is very prominent due to the foam. Internal heat is not easily dissipated, and the temperature automatically rises above 180°C during the foaming process, which can cause the foam to self-ignite and cause a fire hazard. There are three solutions at home and abroad: negative pressure foaming technology, forced cooling technology, and liquid CO2 foaming technology.

The characteristics of polyurethane sponge: The product has even foam, good gloss and hardness control. Applicable industries: automotive, medical, electronics, makeup and other industries, can be produced according to customer requirements, a variety of styles, shapes, sizes.
