Is it important to predry PET and impact modifier to get high impact strength PET ?
A: When we using the PET impact modifier to improve the PET impact strength and toughness and flexibility and make the PET product not easily getting broken .
but should i still need to predry PET resins ?
B : Yes sure , even add the impact modifier , still need to predry the PET resins to remove all the moisture inside .
because the PET resins easily absorbing moisture , and moisture will make the PET very brittle . impact modifier is for improving the PET impact strength ,toughness ,flexibilty , not for removing the moisture , so even add the PET impact modifier ,still need to predry the PET resin to solve the moisture problem first . or it will effect the PET impact modifier function .
Meawhile our PET transparent impact modifier have PET as the carrier resin , so need to predry the PET together with our A-868 Transparent PET impact modifier together to remove all the moisture .
Below are our impact modifier instruction label:
