Product Detail

Low Temperature Expanding Microspheres CAS 38742-70-0 Wallpaper Embossing Agent Physical Foaming Powder

Product Overview

CAS 38742-70-0 Low Temperature Expanding Microspheres are eco-friendly physical foaming powder specially designed for wallpaper and wall covering embossing modification. With low-temperature thermal expansion performance and ultra-fine uniform particle size, the microspheres expand stably and evenly under mild heating conditions. It can form delicate, uniform and three-dimensional concave-convex textures on the wallpaper surface, replacing traditional mechanical embossing processes. This product features low activation temperature, excellent slurry compatibility and stable foaming effect, without chemical residues or surface damage. It effectively improves the texture, stereoscopic sense and grade of wallpaper products, being an ideal physical foaming and embossing additive for modern decorative wall materials.

Core Features

Low Temperature Physical Foaming: Achieve uniform expansion at low temperature, no high-temperature damage or yellowing to wallpaper base material. Gentle foaming process ensures intact base fabric and stable product performance.

Exquisite 3D Embossing Texture: Form dense and fine micro-convex structures after expansion, creating soft and delicate embossed patterns. The texture is natural and uniform with strong stereoscopic sense, avoiding rigid mechanical embossing traces.

Excellent Slurry Compatibility: Good dispersion in various wallpaper coating slurries, no agglomeration, precipitation or floating powder. It can be perfectly fused with wallpaper coating systems to ensure consistent surface effect of finished products.

Eco-Friendly & Safe: Pure physical foaming principle, no chemical reaction, no harmful volatile substances and peculiar smell. Compliant with environmental protection standards for interior decorative materials, safe for home and engineering decoration.

Improve Product Durability: The foamed texture is firm and not easy to fall off or deform. It enhances the wear resistance and anti-scratch performance of wallpaper surface, maintaining long-term stable three-dimensional embossing effect.

Product Specifications

Product Name: Low Temperature Expanding Microspheres

CAS No: 38742-70-0

Product Type: Physical Foaming Powder / Wallpaper Embossing Agent

Foaming Temperature Range: 75℃–110℃

Appearance: White Ultra-Fine Powder

Applicable Products: Wallpaper, Wall Covering, Interior Decorative Coating Materials

Core Function: 3D embossing texture, physical foaming, surface decoration upgrading

Recommended Dosage: 1.0%–3.5% (Adjustable according to embossing depth and texture requirements)

Application Scope

Mainly applied to the production and surface modification of various decorative wall materials, including household embossed wallpaper, commercial engineering wall coverings, PVC decorative wallpaper, textured wall coating and interior decorative soft film materials. It is suitable for all wallpaper products that require soft three-dimensional embossing, delicate texture and high environmental protection performance, widely used in home decoration, hotel engineering and commercial space decoration fields.

Usage Guide

Add the expanding microspheres into wallpaper coating slurry under low-speed stirring, and mix evenly at room temperature. Avoid high-speed shear stirring to prevent microsphere structural damage and premature foaming. After full dispersion, apply the slurry evenly on the wallpaper base material through conventional coating process. Complete physical foaming and embossing forming via low-temperature drying and curing. Adjust the dosage, coating thickness and curing temperature appropriately according to the expected embossing effect. Keep raw materials sealed and moisture-proof during operation and storage.

Packaging & Storage

Packaging: 25kg sealed moisture-proof composite bag with inner PE liner, dust-proof and leak-proof, suitable for industrial mass production and long-distance transportation.

Storage: Store in a dry, cool and ventilated warehouse, keep tightly sealed at all times. Avoid direct sunlight, high temperature environment and humid air to prevent spontaneous foaming and caking. The standard shelf life is 12 months under qualified storage conditions.
