lntroduction:

Coace ® K2L is a maleic anhydride grafted composte polyolefin. It is designed to develop a reliable bonding strength in coextrusion processes for the composite structure materials, like aluminum plastic panels, metal plastic pipe, etc.


Coace ® K2L is a maleic anhydride grafted composte polyolefin. It is designed to develop a reliable bonding strength in coextrusion processes for the composite structure materials, like aluminum plastic panels, metal plastic pipe, etc.

The maleic anhydride component in SANMA provides functional groups that can react with other materials to form chemical bonds, creating a strong interfacial adhesion between the layers. This results in improved mechanical properties, such as increased tensile and flexural strength, as well as enhanced resistance to delamination.

SANMA is often used in combination with other materials, such as polyethylene or polypropylene, to create a multi-layered composite structure that combines the desirable properties of each material. The use of SANMA in coextrusion processes allows for the creation of lightweight, high-strength composite materials that are ideal for a range of applications, such as automotive parts, aerospace components, and consumer goods.

Overall, SANMA is an important material in the development of reliable bonding strength in coextrusion processes for composite structure materials. Its unique properties make it an ideal choice for creating strong and durable composite materials that can withstand a range of harsh environments and operating conditions.

Description

Coace ® K2L is a maleic anhydride grafted composte polyolefin. It is designed to develop a reliable bonding strength in coextrusion processes for the composite structure materials, like aluminum plastic panels, metal plastic pipe, etc.

Styrene-acrylonitrile-maleic anhydride copolymer (SANMA) is a commonly used material in coextrusion processes for composite structure materials. In this application, SANMA is used as a bonding layer between different layers of materials, such as metal and plastic, to create a strong and reliable bond.
