PVC Foam and PVC Building Materials
SURECEL™ and PARALOID™ Acrylic Processing Aids and Polymeric Lubricants for efficient processing and high-quality cell structure in PVC foam applications.
SURECEL™ and PARALOID™ Additives for PVC Foam applications
With our innovative range of SURECEL™ and PARALOID™ Processing Aids and Polymeric Lubricants, PVC foam products can be produced using free foam extrusion, Celuka extrusion and co-extrusion. Our additives enhance foam quality and performance during processing and in final products such as facade, cladding, foam profiles, decking, trim, foam core pipe, signage and display, and other PVC building materials.
SURECEL™ Processing Aids facilitate cost efficient foaming of PVC, while PARALOID™ Polymeric Lubricants improve processability and efficiency by promoting metal release from hot equipment surfaces.
SURECEL™ Processing Aids offer a means to optimize foaming of PVC needed in the manufacture of lightweight, yet structurally resistant end-products, regardless of foam thickness.
The uniform cell structure and size achieved in formulations of PVC with SURECEL™ Processing Aids can lead to enhanced physical properties of the resultant PVC foam product such as heat dissipation and a smooth surface finish.
Selection of the correct SURECEL™ Additive requires understanding the impact of molecular weight distribution on melt flow. Dow offers a range of Processing Aids for achieving the desired melt flow, foam structure and surface quality.

A selection of our products
SURECEL™ 4280 Processing Aid
The molecular weight range is tailored for stable foam structures, high cell density and small cell size. Foam thickness is controlled, and surface quality is high especially for wide sheet dies.
PARALOID™ K-185 ER Lubricant
More efficient production of foam sheet can be achieved by minimizing adhesion to high temperature equipment surfaces using this PARALOID™ Polymeric Lubricant.
SURECEL™ T-60 Processing Aid
Due to its proprietary reactive functionality, SURECEL™ T-60 promotes finer foam cell structure and improves gas containment for applications where lower densities are desired.
SURECEL™ 488 Processing Aid
An ultra-high molecular weight grade allowing excellent melt flow and foaming. This grade facilitates high cell density, small cell size and control of foam thickness while maintaining surface finish.
SURECEL™ 466 ER Processing Aid
Our highest molecular weight acrylic processing aid in EMEAI facilitates the production of sheets requiring high thickness and small cell size.
SURECEL™ 467 Processing Aid
Our workhorse processing aid for North America. An ultra-high molecular weight offers outstanding melt strength and efficiency, as well as a stable and uniform cell structure for thicker foam sheets.
SURECEL™ 445 Processing Aid
A very high molecular weight processing aid, which contributes to the production of uniform foam sheets requiring low thicknesses, especially for digital printing.
PARALOID™ K-175 Lubricant
A polymeric lubricant designed for the North American market which facilitates metal release on high temperature equipment surfaces.
