The impact modifiers for PVC They are copolymers of the type MBS (Methyl-Butadiene-Methacrylate), ABS (Acrylonitrile-Butadiene-Styrene), among others, which help to Rigid PVC to dissipate the impact and thus prevent fracture. PVC It is inherently weak to impact and in applications, such as water jugs o rigid profiles, This can help us avoid breakage and thus guarantee quality for the customer. There are different grades for PVC opaque such as transparent, with or without weatherproof properties.
Just like the acrylic-based processing aids, These additives increase the viscosity of the melt during processing, so to avoid rapid thermal degradation, it is recommended to use one of our thermal stabilizers or lubricants.
To improve the performance of this material, reduce its dosage, and save costs, it is recommended to thoroughly review the formulation used to promote polymer melting. Certain adjustments to process conditions can also be made to achieve improvements in this area.
When they are manufactured rigid PVC profiles, This additive helps prevent breakage when cutting during the process, although care must be taken with the whitening that forms during folding.
