I. Differences in Nature 1. Polyester: A general term for polymers obtained through the polycondensation of polyols and polyacids. 2. Resin: An organic polymer that exhibits softening or melting upon heating, showing flow under external force when softened; at room temperature, it is solid or semi-solid, though it may occasionally exist in liquid form. II. Differences in Characteristics 1. Polyester Characteristics: Polyethylene terephthalate (PET) is produced via the polycondensation of terephthalic acid (PTA) and ethylene glycol (EG). Some of this PET is further processed by underwater pelletizing to yield the final product. Fiber-grade polyester chips are used to manufacture polyester staple fibers and polyester filaments, serving as a key raw material for polyester fiber producers.

I. Different natures

1. Properties of polyesters: A general term for polymers obtained through the polycondensation of polyols and polyacids.

2. Properties of resins: Upon heating, they exhibit a softening or melting range; during softening, they tend to flow under external stress. At room temperature, they are typically solid or semi-solid, though they may occasionally exist in the liquid state as organic polymers.

II. Different Characteristics

1. Polyester characteristics: Polyethylene terephthalate (PET) is produced via the polycondensation of terephthalic acid (PTA) and ethylene glycol (EG), with a portion of the PET subsequently converted into pellets through underwater pelletizing. Fiber-grade polyester chips are used to manufacture polyester staple fibers and polyester filaments, serving as the raw material for polyester fiber producers to process fibers and related products.

2. Characteristics of resins: Their relative molecular weights are variable but generally high; at room temperature, they exist as solids, semi-solids, or pseudo‑solids, and may occasionally be liquid. They exhibit a softening or melting temperature range, display flow under external stress, and typically fracture with a conchoidal fracture surface.
