The process aids forPVC, They are acrylic-based polymers that, as their name indicates, help the PVC processing It makes the process simpler and more uniform. It's a material that promotes fusion, or in other words, improves the surface finish and shine of finished products.
Process aids for PVC are used in Rigid PVC However, in general they can be useful because they considerably reduce production downtime and prevent excessive adhesion to the metal of the production equipment.
Our high molecular weight grades increase torque during the process as well as the mass temperature, which can benefit customers who are manufacturing foamed parts.
Lower molecular weight grades help achieve melting without the need for high temperatures in the process. Furthermore, as part of this improved melting, lumps or surface defects in the PVC They are clearly reduced. Process aids also help us achieve greater transparency in the PVC for transparent applications.
When using PVC processing aids It is recommended to have a well-balanced lubrication system because the process aids, being acrylic-based, tend to greatly increase viscosity and can cause rapid thermal degradation if a good stabilizer is not used.
