Maleic anhydride grafted POE(Polyolefin Elastomer) is an important raw material widely used in the field of chemical production. The upstream and downstream related products of maleic anhydride grafted POE mainly include the following categories:

1. Upstream raw materials:

(1) Maleic anhydride: Maleic anhydride is one of the key raw materials of maleic anhydride grafted POE, mainly used for grafting reaction with POE.

(2)POE:POE is a copolymer of ethylene and α-olefin, which has excellent weather resistance, UV resistance, chemical resistance and mechanical properties.

(3) Initiator: The initiator is a compound used to initiate the grafting reaction of maleic anhydride and POE. Commonly used initiators include benzoyl peroxide, azobisisobutyronitrile, etc.

2. Downstream products:

(1) Toughening agent: Maleic anhydride grafted POE can be used as a toughening agent to improve the toughness and impact resistance of plastics. Common applications include plastic products such as polypropylene and polyethylene.

(2) Compatibilizer: Maleic anhydride grafted POE can be used as a compatibilizer to improve the compatibility between different polymers and improve the performance of blends. It is widely used in polymer alloy, composite materials and other fields.

(3) hot melt adhesive: maleic anhydride grafted POE can be used to prepare hot melt adhesive to improve the bonding strength and heat resistance of the adhesive. It is widely used in packaging, shoemaking, automobile and other fields.

In short, maleic anhydride grafted POE plays an important role in the field of chemical production raw materials, and its upstream and downstream related products cover many fields, which is of great significance to promote the development of the chemical industry.
