PRODUCT FEATURES AND APPLICATIONS
* 3700polymeric epoxy-functionalized chain extender.It’s epoxy group can react with terminal hydroxyl ,carboxyl and amino to achieve chain extension improving viscosity, mechanical property and hydrolysis resistance.It can be used in indirect food packing materials.
* 3700 is multi-functional polymer agent.It is intended for increasing molecular weight and viscosity in degraded polymers. By this function, it can be used in low quality recycled polymers and increase strength of PET and PA.
* 3700 has high epoxy-functionalized groups, which can quickly react with condensation thermoplastics and get higher molecular weight polymers.
Features:
-increasingcompatibilityof condensation polymer alloy
-increasing molecular weight and strength , lower melt index
-increasing hydrolysis resistant stability, elasticity modulus and tensile strength
Application:
-Biodegradable material and their polymer alloy, PLA,PBAT,PBS,PHA
-Plastic modification in PC, PBT AND PET
-Other application related with increasing Molecular weight, strength ,rigid modulus and thermal stability.
Processing suggestion:
-Blending extrusion by single or twin screw.
-0.2-1.5phr, in PLA, PPC,PBS and PHAs.
-0.2-2.0%, inPET,PBT,PA and PC
