K3A is a type of chemical functionalized propylene-based copolymer that has a low glass transition temperature (Tg). Copolymers are polymers made from two or more different monomers. In the case of K3A, the copolymer is made from propylene and another monomer that has been chemically functionalized to improve its properties.
Coace®K3A is a kind of chemical functionalized propylene base copolymer with low glass transition temperature. It owns high fluidity during the manufacturing process.
The low glass transition temperature of K3A means that the copolymer transitions from a glassy, brittle state to a more rubbery state at a lower temperature than other propylene-based polymers. This property can make K3A easier to process and improve its flexibility and impact resistance at lower temperatures.
The chemical functionalization of K3A involves the introduction of reactive groups onto the polymer chain, which can improve its adhesion to other materials or enhance its compatibility with fillers and additives. This modification can also provide reactive sites for further chemical reactions, allowing for the synthesis of more complex materials.
K3A copolymers with low glass transition temperature and chemical functionalization are used in a variety of applications, including packaging films, adhesive tapes, and coatings, as well as in the production of composite materials. The low Tg and improved adhesion and compatibility make K3A a versatile material that can be tailored to meet specific application requirements.
To be used as hot melt adhesive for aluminum foil and polypropylene composite sheet.
