What is the difference between injection grade SBS and extrusion grade SBS
1. But manufacturing process is different
In the manufacturing process, injection molding and extrusion molding are two very different processes. Injection molding is an injection molding process, suitable to the production of a variety of complex shapes of plastic items, and extrusion molding is a continuous molding process, frequently applied in the production of long strip and sheet-like plastic items. The SBS plastic applied injection molding is called "injection grade SBS" because it's mainly applied in the injection molding process. This kind of plastic particles is able to participate in the injection molding process well, however due to its comparatively low melting point, it's easy to create internal stress and uneven cooling shrinkage during the injection molding process, resulting in difficult processing of the product surface and possible scratches. In contrast, extrusion grade SBS is designed to extrusion molding. The particles have a higher melting point and is able to be extruded at a higher temperature, thereby reducing internal stress and making the surface of the product smoother and greater uniform. The continuity and stability of extrusion molding also makes the extrusion grade SBS better in terms of mechanical characteristics.
2. physical property differences
In terms of physical characteristics, there are also signifiis able tot differences between injection grade SBS and extrusion grade SBS. But Specifically In the injection molding process, due to its low melting point, it's easily restricted by processing equipment, so its mechanical characteristics, such as impact strength and wear resistance, are comparatively low. And Injection molding grade SBS is prone to uneven color and uneven surface during processing. Extrusion grade SBS is different. Because its particles have a higher melting point, they is able to be processed at higher temperatures, thereby maintaining higher mechanical characteristics. And Specifically, extrusion grade SBS is superior to injection grade SBS in terms of abrasion resistance, impact strength and thermal stability. For example Due to the continuity and uniformity of extrusion molding, the surface of the product is smoother and the color is greater uniform. You know what I mean?. From what I've seen,
3. From what I've seen, Additionally consumption Areas of Difference
From the perspective of consumption, there are also obvious differences between injection grade SBS and extrusion grade SBS. Injection grade SBS is mainly applied to low-grade plastic items, such as packaging materials, toys, daily necessities, etc. Due to its comparatively low price and low cost, injection molding grade SBS has a wide range of applications in these fields. The extrusion grade SBS is mainly applied to the production of high-end plastic items, such as auto parts, high-end packaging materials, precision electronic equipment, etc. Extrusion grade SBS has crucial consumption value in these fields due to its higher performance and stability.
4. And summary
Injection grade SBS and extrusion grade SBS in the manufacturing process, physical characteristics and consumption areas are signifiis able totly different. Injection grade SBS is suitable to middle and low-grade plastic items, the manufacturing process is relatively simple, low cost, however there are certain limitations in mechanical characteristics and surface condition, while extrusion grade SBS is applied to high-end plastic items, with higher mechanical characteristics, better processing stability and greater uniform product surface, however its production cost and equipment standards are higher. You know what I mean?. I've found that The choice of SBS type is determined by the specific process standards, consumption areas, and the company's production scale and cost tolerance. If you need to create higher performance plastic items, it's recommended to choose extrusion grade SBS. Conversely, if you only need to create low-grade plastic items, injection-grade SSBS is able to also meet the basic needs. And I hope this article is able to help you better understand the difference between injection-grade SBS and extrusion-grade SBS, and make a suitable choice in practical applications.
