Nouryon Expancel 031 DU 40

Nouryon Expancel 031 DU 40 is a high-performance dry, unexpanded thermoplastic microsphere blowing agent and lightweight filler engineered for thermoplastics, PVC plastisols, underbody coatings, adhesives, porous ceramics, construction materials, printing inks, and technical textiles. As a leading supplier in India, JITSY provides Expancel 031 DU 40 to all major industrial clusters backed by technical expertise, local stock, and compliant logistics.

Expancel 031 DU 40 features a robust acrylonitrile-based shell filled with volatile gas, expanding physically in a controlled temperature window (Tstart 80–95 °C, Tmax 120–135 °C). This enables fine, uniform cell structures, significant density reduction, and improved insulation and mechanical properties—without chemical residues or process disruption.

Functional Features & Technical Authority

Expancel 031 DU 40 is engineered for:

• Dry, unexpanded microspheres: Free-flowing powder for easy dosing and uniform dispersion.
• Low expansion onset: Expands from as low as 80 °C, ideal for low-to-medium temperature processes including textile screen printing and puff printing inks.
• 40 µm expanded particle size: Delivers smooth surfaces, fine cell structure, and controlled texture in coatings, ceramics, and 3D effect inks.
• Very low expanded density: Achieves substantial weight reduction and material savings per unit volume.
• Closed-cell, compressible structure: Improves insulation, cushioning, impact resistance, and acoustic damping.

Applications & Industry Use

Expancel 031 DU 40 is widely applied in:

• Thermoplastics & PVC Plastisols: Enables lightweight, flexible parts with fine, uniform cell structures for automotive, appliance, and industrial plastics. Reduces density and enhances insulation and impact resistance.
• Underbody Coatings, Paints & Inks: Used in automotive underbody coatings, high-build paints, and especially in puff printing inks for textiles and 3D effect screen printing inks. Delivers density reduction, matting, texture control, and the signature raised “puff” or 3D tactile effect for fashion and branding applications.
• Adhesives, Sealants, Putties & Porous Ceramics: Lowers density, improves gap-filling, reduces shrinkage and cracking, and forms controlled porosity for thermal insulation in ceramics.
• Construction Materials & Technical Textiles: Adds bulk, softness, and improved insulation to mortars, boards, and coated fabrics without increasing weight. Enhances crack resistance and acoustic performance in building products.
• Puff Additive for Textile Printing: As a specialty puff additive, Expancel 031 DU 40 is widely used by Indian textile printers for producing high-quality, soft, and durable raised prints on garments, t-shirts, and fashion textiles.
