Elastomer polyether is an important raw material for chemical production, which is widely used in polyurethane, rubber, coatings and other fields. This article will detail the properties and uses of elastomeric polyethers. Properties of

1. Elastomer Polyether

Elastomer Polyether is a polymer compound, mainly composed of ether bonds, carbon-carbon bonds and ester bonds. The ether bond in its molecular structure makes it have good hydrolysis resistance, acid and alkali resistance and oxidation resistance. In addition, the elastomer polyether also has the following properties:

1. good low temperature toughness: elastomer polyether can still maintain good flexibility at low temperature, not easy to embrittlement, so it is suitable for use in low temperature environment.
2. High elasticity: Elastomer polyether has excellent elastic properties and can absorb a large amount of energy, so it is often used in the manufacture of shock absorption, impact resistance and other products.
3. Oil resistance: Elastomer polyether has good oil resistance and can be used in oil-based media for a long time without being affected. The use of

elastomer polyether as an important chemical raw material, has a wide range of applications in polyurethane, rubber, coatings and other fields, the following will introduce its specific use in these fields.

1. Polyurethane Field

In the polyurethane field, elastomeric polyethers are mainly used for the production of flexible foams. It is mixed with polyols, isocyanates and other raw materials, through the foaming reaction to form polyurethane soft foam. This material has the characteristics of light weight, good elasticity and strong comfort, and is widely used in furniture, car seats, mattresses and other fields.

In addition, elastomeric polyethers can also be used to produce polyurethane sealants, coatings, etc. These products have excellent weather resistance, water resistance, chemical resistance and other properties, can be used in construction, automotive, aerospace and other fields.

2. Rubber field

In the rubber field, elastomer polyether can be used as a rubber modifier to improve the elasticity, oil resistance, low temperature resistance and other properties of rubber. For example, adding a certain amount of elastomer polyether to natural rubber or synthetic rubber can prepare rubber products with excellent performance, such as tires, rubber hoses, seals, etc.

3.

in the field of coatings In the field of coatings, elastomer polyether can be used as a film-forming material, which can improve the elasticity, water resistance, weather resistance and other properties of coatings. For example, after the elastomer polyether is mixed with other resins, pigments, etc., an elastic coating with excellent performance can be prepared, which is widely used for waterproofing, decoration, etc. in the fields of building exterior walls, roofs, bridges, etc.

In short, as an important raw material for the production of chemical products, elastomer polyether has a wide range of applications in polyurethane, rubber, coatings and other fields. Its excellent performance makes it play an important role in many fields, which brings great convenience to people's production and life.
