What is Polymer Crosslinking?

Crosslinking is known as the bridging or interconnecting of two chemical compounds. A crosslinker is the molecule that is employed to create this connection. Crosslinkers can be utilized for all kinds of polymeric materials, and are especially suitable for hybrid resin systems.

Polymer crosslinking is attained through a broad range of chemical reactions under an equivalently broad range of conditions. Catalysts can additionally be employed in this process to make the chemical reaction more efficient.

Standard polymers that benefit from crosslinkers are thermoset plastics including bismaleimides, epoxies, and vinyl resins. In some circumstances, thermoplastics like nylons and polyolefins can benefit.

Two of the unique crosslinkers offered by CABB  are ortho-Diallyl Bisphenol A and 2-Allylphenol.

 JAYHAWK 301 (2-Allylphenol)

2-ALP (2-Allylphenol) has the chemical formula of C9H10O and is additionally known as o-Allyl Phenol.

This crosslinker is a colorless to yellow, mobile liquid and has a 134.18 g/mol molecular weight. It has a boiling point of 220 oC in ambient environments and a specific gravity of 1.02 at 20 oC.

JAYHAWK 301 is a bifunctional crosslinker due to its hydroxy and allyl functionality. It is most effective for the production of hybrid resins such as epoxy-acrylates with synergistic and novel characteristics.

JAYHAWK 302 (ortho-Diallyl Bisphenol A)

ortho-Diallyl Bisphenol A has the chemical formula C21H24O2 and is additionally known as ODBPA. This crosslinker is a thick liquid of a medium color that may sometimes crystallize at room temperature.

It has a flashpoint of more than 200 oC. A tetrafunctional crosslinker, JAYHAWK 302 can be utilized for composites and optimizes the features of thermosetting resins such as bismaleimides and epoxies. It is employed to enhance heat resistance at high temperatures.
