similarity:The end of the molecular chain used for reaction with isocyanate is hydroxyl terminal.difference:Polymer polyol is a kind of vinyl monomer and initiator polymer. Based on ordinary polyether
Polyester polyol is generally formed by condensation (or transesterification) of organic binary carboxylic acid (anhydride or ester) and binary alcohol (including binary alcohol) or polymerization of
The physical and chemical properties of polyether polyols are mainly determined by the types and molecular weights of initiators and oxidized olefins:1. The amount of active hydrogen in the initiator
The production technology of polyether polyol is becoming more and more mature, and each company has its own proprietary technical expertise. For ordinary polyether polyols represented by propylene ox
Polyether polyol is a polymer with polyether bond (- R-O-R -) in its molecule and OH group as its terminal group. It is a low molecular compound (prolactin) initiated by active hydrogen, polymerized w
Polyether polyol (polyether for short) is a kind of synthetic oil with large sales volume at present. It is a linear polymer prepared from ethylene oxide, propylene oxide and butane oxide by ring open
Slow rebound sponge is also called inert sponge, memory sponge, low rebound sponge, slow rebound sponge and zero pressure sensing sponge. Because of the special polyether, the sponge produced has a ce
It is a kind of soft foam with excellent performance due to its high forming resilience. It has the characteristics of light weight, softness, high resilience and high hand comfort, and is also widely
The amount of foam stabilizer determines the cell size of foam product structure. The larger the cell, the thinner it will be. If too much battery is used, it will shrink. To find this, too few cells
