-mainly used to improve PET POLYESTER impact strength/toughness/viscosity / flexibility/shock resistance/cold impact strength/ weatherbility/anti-aging/durability. Advantage of anti cracking additive PET Impact Modifier 1. -improve impact strength ,toughness , viscosity ,shock resistant,cold impact strength and chain and viscosity. NOT EFFECT THE TRANSPARENCY ! 2. -our flexibility modifiers low dosage 2%--4% ,impact strength /flexibility/sofness/viscosity get 40%--70% improvement while with no effect on other physical properties. 3. Solve PET plastics products like sheets /containers /boards etc easily get broken problem ! NOT EFFECT THE TRANSPARENCY ! 4. Good compatibility and dispersion with the plastics polymers, no precipitation or layerings after adding. 5. good balance of flexibility and stiffness for the plastics, no conflicts or clash 6. no fillers, ensure high performance 7. Wide applications in PET films sheets containers bottles boards injection extrusion blowing
