Injection Molding Defect: Fiber Floating – Root Causes and Fixes
2025-06-20
In the injection molding process of glass fiber-reinforced materials, fiber floating is one of the most common surface defects. It appears as an uneven surface caused by exposed glass fibers on the part. This issue not only affects the visual appearance of the product but can also negatively impact secondary processes such as painting, coating, or electroplating. Today, we will take a deep dive in...

The Science and Strength of PPS: A Deep Dive into Polyphenylene Sulfide
2025-07-21
Introduction Polyphenylene Sulfide (PPS) is a semi-crystalline thermoplastic engineering polymer composed of alternating benzene rings and sulfur atoms in its molecular backbone, with the structural formula -[Ph-S]n- (Ph representing a phenyl ring). This unique combination of rigidity and stability has earned PPS the nickname “Plastic Gold.” PPS Long Glass Fiber Reinforced Four Core Properties of ...

Application of Long Glass Fiber Reinforced Composites in Automotive Lightweighting
2025-08-21
With the rapid development of the automotive industry, long glass fiber reinforced thermoplastic composites (LGF) have been increasingly applied. Under the trend of automotive lightweighting, “replacing steel with plastics” has become a mainstream approach. By taking full advantage of LGF’s low linear expansion coefficient, high specific strength, high specific modulus, and excellent dimensional s...

How Much Glass Fiber is Needed to Make Polypropylene Truly Fire-Resistant?
2025-08-29
In modern industrial fields, glass fiber reinforced polypropylene (PP/GF), with its low density, excellent heat and creep resistance, and high cost-performance ratio, has become a “rising star” in industries such as electronics, aerospace, and automotive manufacturing. This material is often used to produce lightweight and thin-walled components as a substitute for steel and conventional engineeri...

A Quick Guide to the Power of Glass Fiber Reinforcement
2025-09-15
When you pick up your phone, take apart an auto part, or look at a home appliance casing, you might not realize that hidden inside these seemingly ordinary plastic products lies a kind of “invisible rebar” — glass fiber (GF). From PP + 20% GF to PA + 60% GF, these reinforcing fibers quietly support the plastic matrix, much like steel bars inside concrete. Today, let’s uncover the mystery of long g...
