lntroduction:

Coace ® W5AF is a glycidyl methacrylate modified polyolefin elastomer with high content of reactive groups.


The high content of reactive groups in Coace ® W5AF makes it particularly suitable for applications where adhesion to other materials is important. The GMA modification enables the material to form strong chemical bonds with other substrates, such as metals, plastics, and composites. This can make it useful in applications such as adhesives, coatings, and composite materials.

Description

Coace ® W5AF is a type of polyolefin elastomer that has been modified with glycidyl methacrylate (GMA) to introduce reactive groups into the polymer structure. This modification allows the material to be more easily cross-linked, which can improve its mechanical properties and make it more resistant to heat and chemicals.

Polyolefin elastomers are a class of materials that combine the flexibility and elasticity of rubber with the toughness and durability of polyolefin plastics. They are often used in applications where a high level of flexibility and impact resistance is required, such as in automotive components, consumer products, and packaging materials.

The high content of reactive groups in Coace ® W5AF makes it particularly suitable for applications where adhesion to other materials is important. The GMA modification enables the material to form strong chemical bonds with other substrates, such as metals, plastics, and composites. This can make it useful in applications such as adhesives, coatings, and composite materials.
