Maleic anhydride grafted TPE
Maleic anhydride grafted TPE is a modified polymer in which maleic anhydride molecules are chemically linked to the main chain of a thermoplastic polyethylene (TPE). This chemical modification significantly changes the properties of TPE and opens up new applications for it.
Why do we link maleic anhydride to TPE?
Increased polarity: TPEs are typically low-polarity polymers. By linking maleic anhydride, polar functional groups (carboxylic acids) are added to the polymer surface. This increased polarity improves adhesion to other materials, especially polar materials.
Improved compatibility: Increased polarity improves the compatibility of TPE with other polymers, fillers, and polar materials. This allows the production of polymer composites and alloys with improved properties.
Increased reactivity: The carboxylic acid groups in maleic anhydride can react with other materials, allowing for further modification of the polymer.
Advantages of MAH-g-TPE
Better adhesion: Due to the increased polarity, MAH-g-TPE has much better adhesion to other materials, including metals, glass, and other polymers.
Better compatibility with fillers: MAH-g-TPE has better compatibility with fillers such as talc, calcium carbonate, and glass fibers. This improves the mechanical properties of polymer composites.
Better dyeability: Due to the increased polarity, MAH-g-TPE has better dyeability and brighter colors can be created on it.
Better printability: The adhesion of ink to the surface of MAH-g-TPE is better, resulting in improved printability.
Greater reactivity: The carboxylic acid groups in MAH-g-TPE allow for greater chemical reactions, allowing the polymer to be modified for specific applications.
MAH-g-TPE Applications
Polymer alloys: As a compatibilizer in polymer alloys to improve compatibility between different alloy components.
Adhesives and sealants: As a binder and adhesion enhancer in adhesives and sealants.
Coatings: As an adhesion and durability enhancer in coatings and paints.
Polymer composites: As an improver of compatibility between the polymer matrix and fillers in polymer composites.
Automotive industry: In the production of interior parts such as dashboards and seat covers due to its soft, flexible and good adhesion properties.
Packaging industry: In the production of multi-layer packaging films to improve the adhesion of layers and barrier properties.
The process for producing MAH-g-TPE
typically involves grafting maleic anhydride onto TPE in the presence of a radical initiator. This process can be carried out in the melt or solution phase.
Ultimately, MAH-g-TPE is a modified polymer with improved properties that has wide applications in various industries. This polymer enables the production of higher performance products by improving adhesion, compatibility, and reactivity.
