Methanol-resistant PU (polyurethane) is a material with special properties.

I. Characteristics

1. Chemical resistance: It has good tolerance to methanol. It can maintain stable performance in a methanol environment and is not easily corroded, dissolved, or degraded in performance by methanol.

2. Wear resistance: Usually has high wear resistance and can withstand a certain degree of friction and wear.

3. Elasticity: It has good elasticity and resilience and can return to its original state after being stressed.

4. Strength: It has a certain strength and can withstand a certain pressure and tension.

II. Application fields

1. Chemical industry: Used for seals, pipes, etc. of methanol storage and transportation equipment, which can ensure the long-term stable operation of equipment in a methanol environment.

2. Automotive field: It can be used for certain parts in the automotive fuel system, such as sealing gaskets, etc., to adapt to the situation where it may come into contact with methanol fuel.

3. Machinery manufacturing: In some mechanical equipment that needs to contact methanol, methanol-resistant PU can be made into specific parts or protective components.

The polyurethane wear-resistant parts produced by Wuhan Lijiali Company are covered with modified polyurethane by a metal skeleton. They have the characteristics of precise dimensions, wear resistance, no fading in strong acids and alkalis, no harmful metal particles in polyurethane, short delivery time and long service life. They are the main suppliers of polyurethane wear-resistant parts for sand mills at home and abroad. They are widely used in the grinding of titanium dioxide by sulfuric acid method, hydrochloric acid method and chloride method. Polyurethane structural parts for grinding metal and gold concentrate in large sand mills of 3000-5000 liters. They also have extensive application achievements in the grinding processes of new energy lithium iron phosphate batteries in aqueous and methanol systems. They are an ideal choice for polyurethane wear-resistant parts of sand mills.
