CAS 38742-70-0 Thermoplastic Expandable Microspheres serve as a special surface modifier for artificial leather to realize goat skin effect. When heated, microspheres expand uniformly and form fine micro-concave-convex structure on the leather surface, generating soft matte goat skin touch. It boasts good compatibility with artificial leather coating systems, stable texture forming performance, uniform grain and lasting surface effect, widely used in PU and PVC synthetic leather finishing proces

Product Detail

CAS 38742-70-0 Thermoplastic Expandable Microspheres for Artificial Leather Goat Skin Effect Additive

Product Overview

CAS 38742-70-0 Thermoplastic Expandable Microspheres are high-end functional surface modifiers specially developed for artificial leather finishing. Relying on unique thermoplastic expansion characteristics, the microspheres expand evenly under moderate heating during leather curing process, forming uniform and delicate microscopic concave-convex texture on the leather surface. This product perfectly simulates natural goat skin soft matte grain and delicate hand feel, effectively upgrading ordinary flat synthetic leather into high-grade goat skin effect leather. Featuring excellent compatibility with PU and PVC leather coating systems, stable texture forming and durable surface effect, it is the ideal core additive for high-quality faux leather texture customization.

Core Features

Authentic Natural Goat Skin Texture: Uniform thermoplastic expansion forms fine and regular micro grain on leather surface, restoring soft, delicate and layered natural goat skin matte touch. It solves the problems of stiff, flat and unnatural texture of ordinary artificial leather.

Stable Thermoplastic Foaming Performance: Controlled thermal expansion with stable particle stretching and shaping. No excessive expansion or shrinkage, ensuring consistent grain uniformity and texture fineness in batch leather production.

Excellent Leather System Compatibility: Ultra-fine powder with good dispersion in PU resin, PVC paste and leather finishing agents. No agglomeration, floating powder or surface defects, maintaining excellent leather flatness and base material adhesion.

Enhanced Leather Surface Quality: Optimizes leather matte performance, improves surface anti-slip and wear resistance, covers minor surface flaws, effectively improves the grade and appearance texture of finished leather products.

Long-Lasting Texture & Durability: The formed micro grain structure is firmly combined with the leather base layer, not easy to fall off or fade after repeated friction and washing. The goat skin effect remains stable with great weather resistance and aging resistance.

Wide Process Adaptability: Suitable for conventional low and medium temperature leather curing processes, no need to change original production lines, low transformation cost and high production efficiency.

Product Specifications

Product Name: Thermoplastic Expandable Microspheres

CAS No: 38742-70-0

Product Type: Artificial Leather Texture Modifier / Goat Skin Effect Additive

Foaming Temperature Range: 80℃–130℃

Appearance: White Ultra-Fine Powder

Applicable Material: PU Artificial Leather, PVC Synthetic Leather, Faux Leather

Core Function: Goat skin grain forming, matte texture modification, surface beautification, hand feel upgrading

Recommended Dosage: 1.0%–3.0% (Adjustable according to texture fineness and matte degree requirements)

Application Scope

Widely used in surface finishing and texture upgrading of various high-grade synthetic leather. Including garment leather, luggage leather, sofa decorative leather, automotive interior leather, shoe upper leather and craft artificial leather. It is specially used for customizing high simulation goat skin effect, helping manufacturers develop high-texture, high-value matte leather products.

Usage Guide

Add thermoplastic expandable microspheres into leather finishing agent or coating slurry under low-speed stirring at room temperature, and disperse slowly and evenly. Avoid high-speed shear stirring and high-temperature preheating to prevent microsphere rupture and premature foaming. After uniform dispersion, coat the slurry on the leather surface according to conventional finishing processes. Complete thermoplastic expansion and goat skin texture forming through standard low-medium temperature drying and curing. Adjust dosage, coating thickness and curing parameters appropriately according to target texture effect. Keep sealed and moisture-proof during operation and storage.

Packaging & Storage

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

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