Product Advantages
Compared with PEA (polyethylene adipate), it offers better low-temperature toughness and a wider processing window with lower risk of thermal degradation. Widely used for polyester TPU, cast elastomers, footwear adhesives, synthetic leather, tubing and casters. Its main limitation is moderate hydrolysis resistance due to ester bonds, so long-term service under high-humidity conditions needs careful consideration.
