Empowering Smarter Glass Fiber Manufacturing & Composite Innovation Changfu Chemical MPE32.

Today, with the continuous upgrading of industrial materials, high-performance silicon-based materials are becoming the core engine driving industrial innovation. As a strategic category of advanced materials, they underpin the transformation and upgrading of manufacturing, new energy, electronics, aerospace, and composite sectors, enabling lighter weight, higher strength, greater durability, and better environmental adaptability for end products.

Relying on its profound technical accumulation, stable production capacity, and strict quality control system, Changfu Chemical has now launched one of its core products, ChangFu^® MPE32. This specialty silane coupling agent features a unique dual-functional molecular structure, combining hydrolyzable silyl groups and flexible polyether segments to deliver outstanding comprehensive performance.

Widely applicable in fiberglass products, reinforced composites, surface treatment systems, and polymer modification, ChangFu^® MPE32 helps customers optimize formulation performance, improve production stability, elevate product reliability, and enhance core competitiveness in high-end industrial applications.

1. Unique "dual-parent" structure, laying the foundation for multi-functional performance

ChangFu^® MPE32 contains a hydrolyzable silane group at one end and a flexible polyether segment at the other, offering six major advantages:

High reactivity: The silane end group can be hydrolyzed and self-crosslinked or form stable chemical bonds with the surface of the substrate.

Long-lasting adhesion: It has strong bonding forces to inorganic materials such as glass and metal.

Excellent hydrophilicity: The polyether segment provides long-lasting hydrophilic, antistatic and wetting properties.

Good flexibility: The long-chain polyether structure endows the molecular chain with excellent flexibility and mobility.

Surface modification ability: It can permanently change the surface properties of materials through chemical anchoring.

Excellent stability: The siloxane bond structure provides better weather resistance, heat resistance and ultraviolet resistance than ordinary organic bonds.

2. Wire Drawing Process: Efficient Lubrication Film Formation to Ensure High-Quality Fiber Production

In the core high-speed wire drawing stage of glass fiber manufacturing, ChangFu^® MPE32 acts as a high-efficiency lubricant and uniform film-forming agent, providing full‑range protection for fiber performance from the production source:

Forms a homogeneous, durable protective film on the filament surface to effectively reduce fiber-to-fiber abrasion and fuzz generation, ensuring stable, smooth running of the high-speed wire drawing process.

Significantly improves monofilament bundling and integrity, preventing filament scattering, breakage and static buildup, maintaining consistent yarn quality and process stability.

Provides excellent surface modification and coupling effects, enhancing interfacial compatibility and bonding strength between glass fibers and various resin matrices, laying a solid foundation for high-performance composite materials.

3. Weaving: Optimize Sizing Performance, Boost Fabric Quality

      In warp sizing, ChangFu^® MPE32 effectively solves key weaving challenges through targeted performance regulation:

Significantly improves warp softness, integrity and opening performance, resulting in smoother yarn feeding and more stable weaving operation.

Effectively reduces fiber opening pressure and mechanical friction, minimizing filament breakage, abrasion and damage during high-speed processing.

Fabric fuzz, lint and surface defects greatly decreases, ensuring consistent quality, uniform appearance and higher production yield.

Maintains a clean, low-odor and low-additive fabric surface, which simplifies washing, dyeing, impregnation and other post-treatment processes.

4. Composite Molding: Strengthen Interface Bonding, Enhance Product Performance

In the preparation of high-performance reinforced composites, ChangFu^® MPE32 acts as an efficient “molecular bridge” to solve the long-standing interface compatibility bottleneck between inorganic glass fibers and organic resin systems.

It forms stable covalent bonds with hydroxyl groups on glass fiber surfaces through hydrolyzable silane terminals, providing firm and durable interfacial anchoring.

Its flexible polyether segments deliver excellent compatibility and miscibility with various resin matrices, effectively reducing interfacial tension and improving wetting and dispersion.

It significantly enhances interface bonding strength and stress transfer efficiency, enabling more even load distribution across the composite structure and reducing internal defects.

By optimizing the interface layer, it greatly improves mechanical properties including tensile strength, flexural strength and impact resistance, while effectively enhancing hydrolysis resistance, moisture resistance and long-term durability of composite products. ChangFu Chemical's ChangFu^® MPE32 focuses on the glass fiber industry. It creates multiple values by optimizing wire drawing and weaving to improve efficiency, ensuring uniform and clean products to enhance quality, and optimizing composite material interfaces to strengthen performance. We look forward to in-depth cooperation with partners from all sectors of the glass fiber industry to jointly promote technological progress and product upgrading in the industry!
