Cold feed vacuum rubber extruder for car seal and door seal
Application:
Cold feed venting rubber extruder is used for the production of the sealing strip in the car and door seal, window seal, and it can usmore than 40% PVC and add NBR materail. Cold feed venting rubber extruder can supply a range of low (<24%), middle (25%-30%), middle-high (31%-35%) and high (36%-42%) acrylonitrile content.
