HTX PVC processing aid for foam boards is an acrylic modified additive specially developed for the production of various PVC foam boards. It targets and solves common problems in foam production. It is perfectly suitable for free foaming and crust foaming processes, and can be used for advertising foam boards, decorative foam boards, furniture foam boards, building thermal insulation foam boards and other products. It is an optimal additive for mass production and high-quality finished PVC foam boards.

In the production of PVC foam boards, common problems such as uneven plasticization, inconsistent cell size, board collapse, rough surface and uneven thickness greatly affect product quality and yield. This dedicated HTX additive accelerates uniform plasticization of PVC resin, improves material fluidity, stabilizes the extrusion process, and thoroughly solves the problems of uneven melting and unstable discharging.

The core advantage of this product is greatly improved melt strength and stable foaming structure. With a long-chain polymer entanglement structure, it firmly locks internal foam cells to form fine, uniform and independent pores. It effectively prevents cell merging, cracking, collapse and shrinkage, and fundamentally solves quality defects such as board unevenness, deformation and delamination.

Adopting a low-dust and high-purity formula, this product features excellent compatibility. It works perfectly with conventional PVC raw materials including foaming agents, stabilizers, fillers and color masterbatches. No precipitation or migration occurs during production, and it will not affect the original color and appearance of boards. The finished boards are flat, smooth and uniform in gloss without secondary polishing, effectively saving production costs.

Meanwhile, this additive effectively reduces defective products, stabilizes board dimensional accuracy, and balances the hardness, toughness and impact resistance of foam boards. It enables foam boards to have a flat appearance and stable structure. Widely applicable to all kinds of PVC foam products, it helps manufacturers achieve high-speed stable production, improve product quality and reduce production loss.
