Applicazione

Polymer crosslinking agent (Core Application)

1, 3-bis (4,5-dihydro-2-oxazolyl)benzene is used for crosslinking modification of engineering plastics such as polyester, polyamide, and polyolefin: by reacting with carboxyl and hydroxyl groups in the material to form a three-dimensional network structure, it enhances the heat deflection temperature, impact resistance, and solvent resistance of the plastic (for example: The heat resistance of modified PET polyester makes it suitable for components in high-temperature environments.

Rubber vulcanization crosslinking agent: 1, 3-bis (4,5-dihydro-2-oxazolyl)benzene can replace traditional sulfur or peroxides and is used for the vulcanization of nitrile rubber, chloroprene rubber, etc. It has a high crosslinking efficiency and the tensile strength and aging resistance of the finished rubber are better.

Polymer monomer/copolymer monomer

Participate in copolymerization reactions to prepare functional polymers: for instance, copolymerize with dicarboxylic acids (such as adipic acid) to synthesize polyoxazolin-polyester copolymers, or copolymerize with epoxy monomers to prepare high-performance epoxy resins, which are used in adhesives, coatings, etc.

The graft polymer containing oxazoline groups, 1 3-Bis (4 5-dihydro-2-oxazolyl) Benzene, was prepared for interface modification of composite materials (to enhance the binding force between fibers and matrix resins).

Composite material additives

1 3-Bis (4 5-dihydro-2-oxazolyl) Benzene as an interfacial compatibilizer for glass fiber reinforced plastics (FRP) and carbon fiber composites: The oxazoline ring reacts with the hydroxyl and carboxyl groups on the fiber surface, and at the same time cross-links with the base resin to improve the interfacial bonding and enhance the mechanical properties of the composite material (such as flexural strength and impact strength).

Modification of coatings and adhesives: 1 3-Bis (4 5-dihydro-2-oxazolyl) Benzene is added to polyurethane coatings and epoxy adhesives to enhance the adhesion, water resistance and weather resistance of the products, and is suitable for high-end scenarios such as automobiles, electronics and construction.

Other special uses
