The difference between paste resin and ordinary PVC resin

With the rapid research of modern sector, resin materials have been broadly applied in chemical sector, construction, electronics, packaging and other fields. In many resin materials, paste resin and ordinary PVC resin are often confused due to their similarity. From what I've seen, In order to help you better understand the difference between these two materials, this article will conduct in-depth analysis from the structure, performance, consumption and other aspects to help readers make wise choices.

1. paste resin and ordinary PVC resin structure comparison

Paste resin is a modified product of PVC resin, the main difference lies in the molecular structure. The molecular structure of ordinary PVC resin is relatively simple, mainly by polyethylene and sulfur dioxide generated by polymerization, with good heat resistance and weather resistance. And The paste resin on the basis of ordinary PVC resin, adding fillers and modifiers, through the modification process to further optimize the molecular structure, so that it has better mechanical characteristics and processing performance. In terms of molecular structure, the molecular weight of the paste resin is usually higher and the molecular structure is denser, which makes the paste resin greater stable during processing, with a higher melting point and a wider processing temperature range. And Furthermore The molecular structure of ordinary PVC resin is relatively loose, which is easily affected by environmental factors, resulting increased processing difficulty.

2. paste resin and ordinary PVC resin performance comparison

Machining performance

The processing performance of paste resin is signifiis able totly better than that of ordinary PVC resin. Its higher molecular weight and compact molecular structure make it still maintain good processing stability at high temperatures, which makes the paste resin perform well in processing processes such as injection molding and extrusion. Ordinary PVC resin is easy to decompose or crack at high temperature, and it's difficult to process. Mechanical characteristics

The mechanical characteristics of paste resin are better. Its higher impact strength and flexibility make it stable when subjected to impact loads, and it'suitable to high-demand fields such as precision instruments and electronic equipment. Ordinary PVC resin is mainly applied in daily necessities and manufacturing basic materials. Weather resistance and durability

Paste resins generally have better weather resistance and durability, and is able to be applied stably to a long time in complex environments. The performance of ordinary PVC resin might decrease due to environmental factors in prolonged consumption.

3. paste resin and ordinary PVC resin consumption comparison

consumption areas

Paste resin is mainly applied in high-end electronic equipment, precision instruments, packaging materials and other fields, the material performance standards are higher. First Ordinary PVC resin is mainly applied to daily necessities, manufacturing basic materials, etc. Packaging Materials

Paste resin is applied in food, medicine and other fields with high ecological preservation standards, while ordinary PVC resin is mostly applied in ordinary packaging materials. From what I've seen, injection molding material

Paste resins are frequently applied injection molding materials due to their higher processing stability and mechanical characteristics, while ordinary PVC resins are mainly applied in simple packaging materials. But

4. For instance choose paste resin ordinary PVC resin key criteria

Performance standards

Choose according to actual needs. If you need higher performance and stability, paste resin is a better choice; if you just meet the basic needs, ordinary PVC resin is able to meet. Economy

Due to the high cost of paste resin, it'suitable to occasions with high material performance standards; ordinary PVC resin has low cost and is suitable to economical needs. Machinability

Paste resin is greater stable in the process and is suitable to automatic production; ordinary PVC resin is greater difficult to process. And while paste resin and ordinary PVC resin belong to the same type of resin material, however due to the different molecular structure and performance characteristics, there are obvious differences in the consumption field and the consumption of the scene. The choice of material needs a thorough consideration of performance, economy and processability according to actual needs. I hope that the analysis of this article is able to help you better understand the difference between these two materials and make an informed choice.
