Injection Grade Expandable Microspheres CAS 38742-70-0 High Temperature Polymer Processing Foaming Agent

Product Overview

Injection Grade Expandable Microspheres CAS 38742-70-0 are professional physical foaming and lightweight additives specially optimized for high-temperature polymer injection molding processing. Tailored to adapt to high-speed shear and high-temperature molding characteristics of injection technology, these microspheres maintain complete particle structure and stable expansion performance during industrial injection production. They form dense, uniform and independent closed-cell structures inside polymer materials, effectively reducing product density and realizing lightweight modification. While cutting raw material consumption and production costs, the product perfectly retains the mechanical strength, surface flatness and dimensional stability of injection-molded parts. With excellent high-temperature resistance, outstanding fluidity and universal compatibility with various thermoplastic resins, it is a high-performance foaming agent for mass production of lightweight injection plastic products.

Core Features

Professional Injection Molding Grade Design: Optimized particle toughness and pressure resistance, effectively resisting high shear force during high-speed injection molding. Low particle breakage rate, no abnormal foaming or cavity defects, fully adapted to automated injection mass production.

Stable High-Temperature Foaming Performance: Reliable thermal stability under high-temperature polymer processing conditions. Microspheres expand evenly and fully without collapse, cracking or premature foaming, ensuring consistent foaming effect for each batch of products.

Efficient Lightweight & Cost Optimization: Delicate and uniform closed-cell structure greatly reduces the weight of injection products. It lowers raw material usage per product, significantly reduces production costs while ensuring the basic structural performance of plastic parts.

Excellent Fluidity & Dispersion: Good powder fluidity and resin compatibility, uniform dispersion in plastic melts without agglomeration. It will not block injection nozzles or affect molding efficiency, perfectly matching continuous injection production.

Superior Dimensional & Surface Quality: Effectively inhibits thermal shrinkage, warping and deformation of injection-molded parts. Avoids surface bubbles, pits and uneven texture, ensuring smooth surface and high dimensional accuracy of finished products.

Safe & Eco-Friendly Physical Foaming: Adopts pure physical thermal expansion principle, no chemical decomposition, low odor and low VOC. Complies with international environmental protection standards, suitable for industrial, civilian and electronic plastic injection products.
