CAS 38742-70-0 Ultra High Temperature Microspheres for Automotive Lightweight Composites

Product Overview

CAS 38742-70-0 Ultra High Temperature Microspheres are high-performance lightweight functional fillers custom-developed for automotive lightweight composite materials. Optimized to withstand high-temperature compounding and molding processes of automotive composites, these microspheres retain intact particle morphology and deliver consistent expansion performance under rigorous production conditions. Fine, uniform and independent closed-cell structures are formed within composite matrix, significantly lowering component density and raw material consumption. While achieving efficient weight reduction, the product maintains favorable mechanical properties, thermal resistance and dimensional stability required for automotive composite parts. With outstanding high-temperature stability and excellent compatibility with diverse composite formulations, it serves as an ideal additive for lightweight components of new energy vehicles and conventional automobiles.

Core Features

Excellent Ultra-High Temperature Stability

Reinforced shell structure endures high processing temperatures during composite mixing and forming. Microspheres expand evenly without premature foaming, particle rupture or cell collapse, adapting to continuous industrial mass production.

Reliable Compatibility with Composite Systems

Disperses uniformly in various polymer composite materials without agglomeration. It will not impair interfacial bonding between resin and fillers, and imposes minimal adverse impact on the overall mechanical performance of finished composites.

Efficient Lightweight & Cost Control

Dense closed-cell structure realizes stable weight reduction for composite parts. Material consumption and comprehensive manufacturing costs can be reduced while meeting automotive lightweight design targets.

Low Defect Rate & Good Surface Quality

Optimized particle toughness resists shear force during compounding. Less broken microspheres avoid surface bubbles, pits and uneven texture, satisfying appearance requirements of automotive composite components.

Guaranteed Dimensional Consistency

Balances internal stress generated during composite curing and molding, effectively inhibiting shrinkage, warpage and deformation, improving yield rate of precision automotive composite products.

Environmentally Friendly Physical Foaming Solution

Operates via pure physical thermal expansion mechanism, no chemical decomposition, low odor and low VOC. Complies with mainstream environmental standards for automotive interior and exterior composite parts.
