PVC grade HPMC Hydroxypropyl Methyl Cellulose is a cellulose ether derived from cellulose, and it is commonly used in the manufacturing of PVC (polyvinyl chloride) products.
In PVC, HPMC is typically used as a dispersant, thickener, or binder.
As a dispersant, HPMC helps to disperse the PVC resin particles in the solvent, resulting in a more homogeneous mixture. This can improve the quality and consistency of the PVC products.
As a thickener, HPMC can increase the viscosity of the PVC resin solution, making it easier to control the flow and improve the properties of the final product.
As a binder, HPMC can improve the adhesion between the PVC and other substrates, such as wood, metal, or concrete. This can be particularly useful in construction and other applications where PVC is used as a coating or adhesive.
