PVC is a polar polymer. The structure contains Cl, which makes the structure less flexible and more rigid. At the same time, due to the presence of Cl, it is easy to break down chains under thermal or ultraviolet conditions, which results in increased fragility.
PVC has a high melt viscosity and poor fluidity, and the fluidity changes little even with increasing injection pressure and melt temperature. In addition, the forming temperature of the resin is very close to the thermal decomposition temperature, the temperature range that can be formed is very narrow, and it is a difficult material to be formed.
For the performance characteristics of PVC, the solution of Kaneka include weatherproof impact modifier (acrylate ACM), high impact modifier (MBS), and processing aids (acrylic ACR). Focus on solving the shortcomings of poor processing performance and brittleness of PVC products.
How to choose the right product depends on your application. We always suggest you contact us to discuss your needs
Kaneka PVC plastic additive is suitable for various applications, including extruded pipe, extruded profile, calendered sheet, salivated sheet, injection molded parts, foamed products, blown film and so on
Kaneka® PA Processing modifer–Acrylate polymer（ACR） can provide PVC with efficient, smooth surface, rapid fusion and highly homogeneous melt, and improve processing performance and product surface effect. Used in PVC foaming process to stabilize melt strength and produce lower density, higher foaming rate and very fine cell structure.
Kaneka ® B Impact modifier – The ternary copolymer MBS of methyl methacrylate (M), butadiene (B) and styrene (S) has a typical core-shell structure, which improves the impact resistance of PVC materials. The excellent balance between transparency and impact resistance is especially suitable for transparent PVC products
.Kaneka ® FM Impact modifier – Acrylate polymer（ACM）, a weather resistant impact modifier, is particularly suitable for outdoor PVC products
