    Abstract: The disclosure provides a liquid molding compound and preparation method thereof, belonging to the technical field of semiconductor packaging. The liquid molding compound includes: the following components in mass fraction, a filler 83%-88%, an epoxy resin 6%-9%, a curing agent 6%-9%, a colorant 0.1%-0.2%, an accelerator 0.1%-0.3%, and a paraffin oil 0.3%-0.6%; by adding paraffin oil that has a small surface activity, paraffin oil does not participate in the reaction between epoxy resin and curing agent, is easily compatible with epoxy resin, and easy to precipitate under heating conditions. The precipitated paraffin oil forms a spacer layer between the colloid surface and the thermal release tape. The paraffin oil of the spacer layer has almost no adhesion to the acrylic adhesive on the thermal release tape, so the thermal release tape can be easily removed at a certain temperature to achieve the effect of no residual adhesive.

    Abstract: Rubber formulations include a rubber and a norbornylized seed oil. The norbornylized seed oil is a seed oil that is modified with norbornylene groups. The norbornylized seed oil can replace petroleum oils currently often used in rubber formulations. A process for creating a rubber formulation includes the steps of adding a norbornylized seed oil to a rubber, wherein the norbornylized seed oil is a seed oil modified with norbornylene groups.
