Core Definition of the Product
Low Carboxylic Polyester Chips are characterized by low terminal carboxyl content and strong processing adaptability. They mainly serve downstream scenarios with basic requirements for material stability and hydrolysis resistance, such as monofilament production.
Core Product Features
1.Controllable Terminal Carboxylic Content, Supporting Customized Requirements
The terminal carboxyl content of Low Carboxylic polyester chips is strictly controlled at ≤12% mol/t. Customized carboxyl content adjustments can be provided according to the specific processing technologies and application scenarios of downstream customers.
2.Superior Chemical Structure and Outstanding Mechanical Stability
Low Carboxylic polyester chips have relatively lower carboxyl content in their molecular chains,and the molecular chain distribution, crystallinity are better, and the linearity is better. This gives it certain advantages in mechanical properties such as stability.
3.Excellent Hydrolysis Resistance, Suitable for Humid Scenarios
One of the key performance highlights of Low Carboxylic polyester chips is their hydrolysis resistance:Since the terminal carboxyl group is a hydrophilic group, the lower its content, the less likely it is to undergo hydrolysis reactions and cause performance degradation when in a humid environment or in contact with water.
4.Stable Processing Performance, Adaptable to Multiple Processes
During processing, Low Carboxylic polyester chips demonstrate two key advantages: it has good thermal stability, can maintain stable performance under certain high – temperature conditions, and is less likely to affect the processing quality due to problems such as thermal decomposition. Its spinnability is also relatively good, enabling smooth subsequent processing such as spinning.
5.Wide Application Scenarios, Focusing on High-Demand Fields
As a spinning raw material, Low Carboxylic polyester chips can be used to produce textile fibers with certain washing resistance and deformation resistance, meeting the basic needs of mid-to-high-end clothing and home textile fabrics.
In low-end engineering plastic scenarios with relatively high requirements for material stability (e.g., small household appliance casings, simple mechanical parts), Low Carboxylic polyester chips can ensure the long-term usage reliability of the parts through their excellent mechanical properties
