This is because catalysts lower the activation energy required for the reaction to occur, which makes it happen faster. The fillers are inert materials and they impart strength and hardness. This is because the fillers fill in the spaces between the resin molecules, which makes the material stronger and harder. Fibrous fillers increase thermal resistance.
