Conductive plastics represent a revolutionary class of materials, achieving a remarkable transformation from insulator to semiconductor to conductor—arguably the most significant property span possible in any material class. They uniquely combine the electrical conductivity of metals (where an ... Read More

Polybutylene Terephthalate (PBT) is a semi-crystalline engineering plastic valued for its excellent electrical properties, chemical resistance, fast crystallization rate (leading to short molding cycles), and good mechanical strength. However, when modified—especially with glass fibers—several ... Read More

Glass fiber reinforcement is a fundamental technique for enhancing the properties of thermoplastics like PP, ABS, PA6, PA66, PC, POM, PBT, and PPS. By adding typically 10% to 60% glass fibers, the material transitions from a general-purpose plastic to a structural engineering material. Understanding ... Read More

PBT features a saturated linear molecular structure with alternating rigid benzene rings and flexible aliphatic chains, providing high mechanical strength, chemical/heat resistance, and excellent electrical properties. Its symmetrical structure enables tight packing, high crystallinity, and a high ... Read More

Demolding challenges in glass-fiber reinforced PA6 injection molding typically arise from: Improper mold temperature control (too high or too low), causing uneven shrinkage and clamping force. High residual stress in the part, increasing required ejection force. Solutions include: Reducing injection ... Read More

Light-colored ABS (white, beige, gray) is prone to yellowing due to unsaturated double bonds in its molecular chain, which degrade under light, heat, and oxygen exposure. This weathering issue affects aesthetics and customer satisfaction, especially in applications like家电 casings and automotive ... Read More

Processing PC/ABS blends can present specific challenges. Here is a consolidated guide to the seven most frequent problems and their targeted solutions to ensure high-quality production. Silver Streaks: Manifesting as silver-white streaks, this is caused by gas interference—entrapped air, material ... Read More

Plastic alloys represent a advanced class of materials created by physically blending or chemically grafting different polymers to achieve new, high-performance, functional, and specialized properties. These alloyed products find widespread use in demanding sectors such as automotive, electronics, ... Read More

Successful injection molding of PBT requires careful attention to its specific process parameters. The melting temperature is critical, with a narrow range of 250-260°C; processing below 240°C can cause condensation, while temperatures above 270°C lead to thermal degradation. A barrel constant ...

The "floating fiber" phenomenon remains a significant surface quality challenge in the injection molding of glass fiber reinforced Polycarbonate (PC). This issue arises from the inherent differences between the polymer and the reinforcing fibers. During injection, the differing densities and flow ... Read More
