Polyester Polyol is a core hydroxyl‑terminated intermediate formulated for manufacturing moisture‑cure hot‑melt adhesives. It reacts with isocyanate components to build polyurethane molecular networks. This polyol delivers balanced hardness, flexibility and thermal resistance for finished adhesive systems. It serves as a critical raw material for producing PU sealants as well as woodworking, automotive and textile bonding adhesives. JSY offers consistent bulk supply for polyurethane formulators

Typical Technical DataAppearance: Pale yellow viscous liquid or waxy semi‑solid Color (APHA): ≤150 Hydroxyl Value: 45‑75 mgKOH/g Acid Value: ≤1.2 mgKOH/g Melting Range: 45‑65℃ Water Content: ≤0.10% Viscosity (80℃): 2000‑6000 mPa·s

Key Features & Advantages

Controlled hydroxyl content enables predictable isocyanate cross‑linking for moisture‑cure systems
Balanced crystalline‑amorphous structure gives hot‑melt adhesives good initial tack and final peel strength
Provides favourable low‑temperature flexibility for finished polyurethane adhesive layers
Compatible with common isocyanate, catalyst and auxiliary additives for PU formulation
Versatile intermediate suitable for sealant as well as wood, automotive and textile bonding systems

ApplicationsPU Sealant ProductionUsed as primary polyol raw‑material for one‑component moisture‑curing PU sealant, improving elongation and substrate adhesion of cured sealant.

Woodworking Hot‑Melt AdhesiveFormulated into reactive hot‑melt adhesives for edge‑banding, panel lamination, delivering durable bonding on wooden substrates.

Automotive AdhesiveApplied for manufacturing reactive hot‑melt adhesives used for interior trim bonding inside automotive assemblies.

Textile Laminating AdhesiveServes as PU intermediate for textile laminating adhesives, providing flexible bonding for fabric composite materials.

Packaging, Storage & Shelf LifePacked in 200 kg steel drums. The material is sensitive to moisture. Keep drums hermetically sealed at all times. Store within dry, cool and well‑ventilated warehouse. Strictly isolate from water vapour, humidity and isocyanate substances. Shelf life is 6 months under recommended dry storage conditions.

Compliance NoteThis industrial polyurethane intermediate is not intended for direct food‑contact use. End‑formulators shall carry out their own compliance testing for finished articles.
