PVC resin powder is a broad term encompassing various types of PVC resins, including paste resins. These paste resins exist in a unique liquid form and are created through lotion and micro-suspension methods. The fine particle size of PVC paste resin gives it a talc-like texture and when mixed with plasticizers, it forms a stable suspension for further processing into final products.

PVC resin powder is a general term, so PVC resins include paste resins. As the name suggests, PVC paste resins are mainly used in the form of a paste. People often refer to this paste as plasticized paste, which is a unique liquid form of PVC plastics in the unprocessed state.

Paste resin is usually prepared by lotion and micro suspension methods. Due to its fine particle size, polyvinyl chloride paste resin has a texture similar to talc powder and is non flowing. After mixing PVC paste resin with plasticizer, it is stirred to form a stable suspension, which is then made into PVC paste, or PVC plasticizer paste, or PVC sol. It is in this form that people use to process into final products.
