PVC Paste Resin P-450 is a low-molecular-weight emulsion-grade polyvinyl chloride homopolymer engineered specifically for chemical foaming applications. With the CAS number 9002-86-2 and a K-Value of 65–68, it appears as a white fine powder with a polymerization degree of approximately 1,000 — the lightest molecular weight in the paste resin family.
P-450 is purpose-built for excellent foamability. Its low molecular weight, medium Brookfield viscosity, and superior air-release properties produce plastisols that expand into uniform, fine-cell foam structures with exceptional stability — making it the industry-standard resin for foamed vinyl flooring, cushioned wall coverings, foam sheets, and the foam layers in premium artificial leather.
P-450's low molecular weight and outstanding foam characteristics make it the definitive choice for expanded PVC products — where controlled cell formation, surface smoothness, and mechanical cushioning are the defining quality metrics.
P-450 is the foundational resin for chemically foamed PVC floor coverings — from luxury vinyl tile (LVT) foam cores to cushioned sheet flooring. Its uniform cell structure and stable expansion ratio deliver consistent thickness, excellent underfoot comfort, and precise embossing pattern retention across production runs. The resin's low gelation temperature enables energy-efficient processing and rapid cycle times.
In expanded PVC wallpaper and decorative wall panels, P-450 plastisols create the characteristic three-dimensional foam patterns through controlled chemical blowing. The resin's fine cell distribution produces smooth, matte surfaces with high opacity, excellent printability, and stain resistance — essential for premium residential and hospitality interiors.
P-450 serves as the foaming interlayer in multi-layer PVC artificial leather constructions for automotive seating, furniture upholstery, and footwear. The foam core provides the soft hand feel, compression recovery, and weight reduction that distinguish premium synthetic leather from solid-coat alternatives.
In extruded and cast PVC foam sheets for packaging, insulation, and sealing applications, P-450 provides the expansion control and closed-cell structure needed for consistent density, thermal insulation, and moisture barrier performance.
P-450 plastisols are used in rotational molding of hollow parts and in automotive interior trim components where foam backing adds acoustic insulation, impact absorption, and a premium tactile finish.
