Sponge is a kind of polyurethane foam, and it is also a kind of soft
polyurethane foam.
Because of its porous honeycomb structure, the sponge has excellent
characteristics of softness, water absorption, elasticity and water resistance,
which m...
High density sponge refers to the sponge with a net weight of 45KG per cubic
meter.
Generally speaking, high-density sponge has good air permeability and other
characteristics, so it is related to various industries, including automotive
indus...
The formula of slow rebound sponge is more or less the same as that of
ordinary sponge.
In addition to the main material polyether is quite different, some small
materials can be used with each other.
However, in order to produce high-quali...
There are two kinds of polyurethane sponge foaming machine: hard foam and
soft foam. in order to make us know more about hard foam and soft foam, we will
briefly introduce the difference between these two kinds of foam.
The structure of rigid f...
I often receive calls from colleagues from all over the world to ask about the various technical problems in the production of slow rebound sponges. In fact, these problems are encountered by everyone in the actual production process, including my...
The yellowing of polyurethane foam sponge has been a problem that has
perplexed sponge manufacturers and polyol manufacturers for a long time.
Many sponge manufacturers, especially some high-grade sponge manufacturers,
try to improve the anti-y...
According to the track of raw material movement:
tank-filter-pump-pipe-steering pneumatic valve-mixing chamber-pouring
Storage tank: the size of the tank should be related to the foaming site, the
tank is too big, too small, too thick, too thin...
1. High closed pore rate.
(1) Polyether polyols: high proportion of ethylene oxide, high activity,
often occurs in the replacement of polyether polyols with different
activities.
(2) process formula: large amount of stannous octanoate, high...
