PVC Processing Aids are acrylic-based polymers that, as their name suggests, help make PVC processing easier and more consistent. It is a material that promotes fusion, or, in other words, improves the surface finish and gloss in finished products.
Process aids for PVC are used in rigid PVC, however, in general, they can be useful as they considerably reduce production stoppages and avoid excessive adherence with the metal of the production equipment.
Our high molecular weight grades raise in-process torque as well as dough temperature, which can benefit customers involving the manufacturing of foamed parts.
Lower molecular weight grades help achieve melting without the need to use high temperatures in the process. Also, as part of this improved melting, lumps or surface defects in the PVC are clearly reduced. The process aid also helps us achieve greater transparency in PVC for transparent applications.
When using processing aids for PVC, it is recommended to have a well-balanced lubrication system because process aids, being acrylic based, tend to increase the viscosity a lot and can cause rapid thermal degradation if they do not have a good stabilizer.
| Product Grade | Application | Key features |
| Akrelon PA 120 | PVC Fitting, PVC Window Profiles, Rigid PVC Sheet, SPC and PVC Laminate Sheet | Imparting excellent compatibility in PVC and faster fusion, AKRELON PA 120 improves melt strength and surface gloss significantly, which as a result ensures required dimensional stability and surface properties in the processes of PVC applications. |
| Akrelon PA 220 | PVC Fitting, PVC Window Profiles, Rigid PVC Sheet and PVC Laminate Sheet | AKRELON PA 220 is the best in class, highly versatile, most efficient general purpose Processing Aid that can address almost the entire range of vinyl processors – from films to pipes and building products. |
| Akrelon PA L175 | PVC Window Profiles, Rigid PVC Sheet, SPC and PVC Laminate Sheet, Foam Sheet | AKRELON PA L175 is a low molecular weight lubricating processing aid which can be used in any PVC application to ensure efficient external lubrication and die release without delaying fusion. Thanks to its polymeric structure and well balanced molecular weight, it forms a very heat stable and non-sticking lubricating film which improves surface finish significantly and avoids sticking in the hot die or calendering rolls. |
