The 27th China (Yuyao) International Plastics Expo 2026

Exhibition Review

Replacing Metal with Plastic for a Lighter Future

Gathering in Yuyao to Explore the Future of Advanced Materials

The 5 Most Frequently Asked Questions at the Exhibition

After four days at the expo, one thing became clear: Almost nobody visiting Booth 1001 started by asking, "What grades do you offer?" Instead, they wanted to know: Can your material replace this metal part? And does it make economic sense?

Q1 What Is the Difference Between Long Glass Fiber and Short Glass Fiber

Short glass fibers are only a fraction of a millimeter long, providing point reinforcement and primarily improving stiffness. Long glass fibers retain lengths of 5–25 mm, forming a three-dimensional reinforcing network within the polymer matrix to deliver a combination of strength, impact resistance, and fatigue resistance.

The key difference lies in their failure behavior. Short-fiber reinforced parts are more prone to brittle fracture under impact, while long-fiber reinforced parts can better withstand repeated impacts. This is one of the key reasons why LFT materials can replace certain metal structural components.

Q2 How Does the Cost Compare with Metal and Short-Fiber Materials

The key is to evaluate the total part cost, not just the material price. A single injection molding process can eliminate additional steps such as stamping, welding, painting, and assembly. With a density of just 1.2–1.4 g/cm³, LFT materials also offer significant weight reduction, while processing efficiency can improve by more than 60%.

What matters is not how much one kilogram of material costs, but how much the customer can save annually.

Q3 How Can Metal Structural Components Be Made Lighter

Long fiber reinforced thermoplastics offer more possibilities for replacing metal with plastics, helping manufacturers achieve lightweight designs without compromising structural performance.

Q4 Long Glass Fiber or Long Carbon Fiber Which Should You Choose

LGF offers a balance of strength and impact resistance, while LCF focuses on higher stiffness and lightweight performance. The right choice depends on the mechanical requirements and application.

Q5 Can Materials Be Customized for Special Applications

Yes. From resin systems and fiber content to specific performance requirements, we provide customized material solutions tailored to individual projects.
