Welcome to our exhibitionFEIPLAR COMPOSITES & FEIPUR 2024 Polyurethane, modified MDI, polyether polyols, silicone oil, amine catalysts
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 make i...
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 industry, ...
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-quality product...
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 foam o...
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-yellow...
According to the track of raw material movement: tank-filter-pump-pipe-steering pneumatic valve-mixing chamber-pouringStorage tank: the size of the tank should be related to the foaming site, the tank is too big, too small, too thick, too thin will...
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 activity ...
