UB-302L Melting Point: 180±5°C

Description

Ubest specializes in customized low-melting-point PET resin, with a controllable melting point range of 110–240℃. Products can be tailored to meet specific customer requirements for a variety of industrial applications, including textiles, building materials, coatings, shoe materials, hot melt adhesives, and masterbatches.

Key Product Applications

1. Masterbatches

• Low-melting-point PET chips for masterbatches melt quickly, exhibit excellent fluidity and dispersibility, and ensure uniform color dyeing.

• Ideal as carriers for polyester dyes.

• Particularly suitable for high-speed spinning dyeing such as POY and FDY.

• Offers bright, saturated colors with good color fastness.

2. Spinning

• PET for spinning has high viscosity, excellent spinnability, and consistent crystallization.

• Suitable for full-melt yarn, skin-core yarn, and other yarn types.

• Narrow melting range ensures uniform dyeing without streaks.

• Copolyester variants are available to improve dyeability under normal temperature and pressure.

3. Film Drawing

• Used to produce heat shrink films and heat sealing films.

• Heat shrink films offer 30–65% shrinkage, with uniform contraction, minimal warping, and few crystal points.

• Heat sealing films provide excellent sealing performance and are easy to print.

4. Coatings

• Low-melting-point PET improves polyester-type coating performance.

• Molecular weight and melting point can be customized per customer specifications.

• Features include low B value, low hydroxyl value, and low acid value, enhancing coating quality and consistency.

5. Other Applications

• Widely used in shoe materials, hot melt adhesives, building materials, engineering plastics, and other industrial purposes.
