Differences in chemical composition between polyether silicone oil and polyurethane foam additives
Polyether silicone oil and polyurethane foam additives are different in chemical composition, functional characteristics and application fields. Here is a detailed comparison between the two:

1、 Chemical composition
Polyether silicone oil
Polyether silicone oil is a modified silicone oil that contains hydrophobic groups (silicone oil groups) and hydrophilic groups (polyether groups) in its molecular structure.
It is usually prepared by combining polyether with hydrogen containing silicone oil through specific chemical reactions, such as hydrosilylation reaction.
Polyurethane foam additives
Polyurethane foam additives are a series of chemical additives used in the production of polyurethane foam plastics.
These additives may include catalysts, foam stabilizers (foam stabilizers), foaming agents, etc. Their chemical compositions are different, but they act together on the formation and performance optimization of polyurethane foam.
2、 Functional characteristics
Polyether silicone oil
Having lower surface tension facilitates the spreading of liquids on solid surfaces and improves wetting performance.
It can quickly wet the surface of materials, improve the uniformity and adhesion of coatings, inks, etc.
It has good emulsification and dispersibility, which can promote the mixing of oil-water phase and improve the stability of the dispersion system.
Has excellent lubrication performance, can reduce friction, and extend equipment life.
It has remarkable defoaming and foam suppression ability, and can effectively control the generation and elimination of foam.
Polyurethane foam additives
Catalyst: used to accelerate the chemical reaction in the production process of polyurethane foam plastics, so as to balance the gel reaction and foaming reaction.
Foam stabilizer (foam stabilizer): used to improve the stability and uniformity of foam and prevent foam from collapsing and bursting.
Foaming agent: It is used to generate gas to make polyurethane foam expand and foam.
3、 Application Fields
Polyether silicone oil
It is widely used in polyurethane foam homogenizer, cosmetic raw materials, plastic additives, antifogging agents, fiber finishes, fabric post-treatment agents, paint additives and other fields.
In the coating industry, it can improve the fluidity, adhesion and durability of coatings, and control the generation of foam.
In daily chemical products such as shampoo and shower gel, they can provide a silky touch and excellent hair care effects.
In the textile industry, it is used as a softener and lubricant to improve the feel and durability of textiles.
Polyurethane foam additives
It is mainly used in the production of polyurethane foam plastics, including soft foam, hard foam, semi hard foam and other different types of polyurethane foam.
The properties of polyurethane foam, such as density, hardness and resilience, can be optimized by adjusting the type and amount of additives.
In conclusion, polyether silicone oil and polyurethane foam additives are significantly different in chemical composition, functional characteristics and application fields. Polyether silicone oil is mainly used as a chemical additive with multiple functions, playing an important role in multiple fields; While polyurethane foam additives focus on the production process of polyurethane foam plastics, and meet the needs of different fields by optimizing the performance of foam.
