Maleic Anhydride Grafted POE Properties, Uses, Upstream and Downstream Raw Materials and Storage Method Analysis

1. maleic anhydride grafted POE

Maleic anhydride grafted POE(Polyolefin Elastomer,POE) refers to the grafting of maleic anhydride through a chemical reaction in POE, so that it has some specific chemical and physical properties. Grafted maleic anhydride POE has the following main properties:

1. Enhanced polarity: Due to the introduction of maleic anhydride, the grafted POE has a stronger polarity than pure POE, enabling it to be better compatible with other polar materials such as polyamide, polyester, etc.

2. Good heat resistance and oxidation resistance: The grafted POE can maintain good stability at high temperatures, and the oxidation resistance is also significantly improved, which makes it excellent in high temperature applications.

3. Enhanced mechanical properties: Through the grafting reaction, the mechanical properties such as tensile strength and impact strength of POE are significantly improved, showing higher strength and toughness.

4. Good processing performance: maleic anhydride grafted POE has excellent processing performance, which can be formed by injection molding, extrusion and other processes, and is suitable for various processing equipment.

2. of maleic anhydride grafted POE for use

Because of its excellent performance, maleic anhydride grafted POE is widely used in many fields, including:

1. Adhesives and tackifiers: Due to its increased polarity, maleic anhydride grafted POE is often used to prepare various adhesives and tackifiers, especially in the automotive and construction industries, for bonding materials such as metals, plastics and rubbers.

2. Blending modifier: As a blending modifier, maleic anhydride grafted POE can be blended with other polymers to improve the compatibility and mechanical properties of blended materials, and is widely used in the field of plastic modification.

3. Sealing material: With its excellent heat resistance and aging resistance, maleic anhydride grafted POE is used as a sealing material, which is suitable for applications that require high temperature resistance and chemical corrosion resistance such as automobiles and electronic equipment.

4. Packaging materials: In the field of packaging, maleic anhydride grafted POE is used to produce high-performance packaging films with good tensile properties and transparency, which can effectively protect internal items.

3. of Maleic Anhydride Grafted POE Upstream and Downstream Raw Materials

1. Upstream raw materials: The production of maleic anhydride grafted POE involves multiple upstream raw materials, mainly including:

• Maleic anhydride: an important chemical raw material prepared by catalytic oxidation from maleic.
• POE: usually by ethylene and 1-octene, 1-butene and other α-olefin copolymerization, has excellent elasticity and weather resistance.

1. Production process: The key step in the production of maleic anhydride grafted POE is to graft maleic anhydride onto the POE molecular chain, usually through a free radical initiated reaction. The specific process involves reacting maleic anhydride with POE at high temperature to produce a product with chemical bond grafting.

2. Downstream Products: Downstream products include a variety of modified materials and products, such as plastic alloys, reinforced plastics, various high-performance adhesives and sealants, which are widely used in automotive, construction, electronics and packaging.

4. maleic anhydride grafted POE storage method

1. Temperature control: Maleic anhydride grafted POE should be stored in a low temperature environment to avoid prolonged exposure to high temperatures to prevent degradation and performance loss. The storage temperature of the recommend is 5-30°C.

2. Moisture-proof measures: the material should be prevented from absorbing moisture, the storage environment should be kept dry, and the packaging material should have a good seal to prevent moisture infiltration.

3. Light protection: Maleic anhydride grafted POE should be protected from direct sunlight to prevent aging and degradation caused by ultraviolet rays. Materials should be stored in a light-protected environment or with light-blocking packaging materials.

4. Packaging requirements: Generally, maleic anhydride grafted POE is packaged in the form of paper bags, plastic bags or metal drums. The outer packaging should be complete and undamaged, and the inner packaging should be well sealed to ensure that the materials are not contaminated.

5. Safety measures: The storage area should be well ventilated and away from fire and high temperature areas. Material Safety Data Sheets (MSDS) should be followed to ensure safety during storage and handling.

Conclusion

Maleic anhydride grafted POE occupies an important position in modern industry due to its unique properties and wide range of uses. From the upstream raw material acquisition, production process, to the downstream application and storage methods, every link needs strict control and management. With its excellent performance, maleic anhydride grafted POE has shown great application potential in many industries, and will be more widely promoted and applied in the future.
