CAS：1191261-43-4| CHAIN EXTENDER TRUELICHT 3700

Introduction and application of CAS：1191261-43-4| CHAIN EXTENDER TRUELICHT 3700

●TRUELICHT 3700 is a polymeric epoxy functional chain extender. The epoxy functional group in its structure can achieve chain extension of the polymer by reacting with the terminal hydroxyl group, carboxyl group and amino group in the resin, thereby improving the characteristic viscosity, mechanical properties and inhibition of the resin. Polymers can be used in food contact materials for hydrolysis purposes.
●TRUELICHT 3700 is a multifunctional polymer designed to restore molecular weight and IV (intrinsic viscosity) in decomposed polymers. It can improve the recycling of low-quality polymers and can be used during processing to improve the melt strength of polyester or polyamide.
TRUELICHT 370 also has high epoxy functionality, which allows rapid reaction with condensation thermoplastics, resulting in higher molecular weights.
●TRUELICHT 3700 has a melting point of 60℃ and a decomposition temperature of 320℃.
The main advantage:
1. Improve the compatibility of condensation polymer alloys
2. Increase molecular weight, improve tensile strength, and significantly reduce melt index.
3. Enhance hydrolytic stability, enhance the elastic modulus, tensile strength, etc. of the material
Areas of use:
- Used for blending modification of biodegradable materials PLA, PBAT PBS PHA and other alloys and fillers (additives must be added)
-Used for blending modification of engineering plastics PC, PBT, PET, etc. and their alloys
-Increase molecular weight (viscosity), avoid molecular chain breakage, reduce melt index, increase tensile strength, increase modulus (rigidity),
-Improve impact strength, increase heat distortion temperature, etc.
application:
Generally, it is blended and extruded with modified resin through twin-screw or single-screw extruders.
Recommended dosage in bio-based and biodegradable plastics such as polylactic acid (PLA), polymethylethylene carbonate (PPC), polybutylene succinate (PBS), polyhydroxyalkanoates (PHAs) is 0.2-1.5phr
The recommended dosage in polycondensation recycled plastics such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), and polycarbonate (PC) is 0.2-2.0phr.
The specific dosage depends on the number of active functional groups in the resin and product performance requirements.
