How do liquid additives filter in the production of soft PVC? May 29, 2018

 

For soft PVC products, different plasticizers with different proportions should be added before production. In order to ensure the molding quality of the products, these plasticizers should be filtered, removed from the liquid material and then proportions according to the requirements of the formula. Then the plasticizers can be weighed separately and then they can be added into the mixed tank. In the mixing tank, mix it up with compressed air, mix it evenly and heat it at constant temperature. Keep it in reserve at 70 C -80 C temperature range.
