PVC products have the advantages of high softness, good pressure resistance, high transparency, easy processing, non-toxic effect, disinfection use, etc., are widely used in the field of medical devices, and the gradual expansion of the market for disposable PVC medical products has also given PVC products greater space for development.

Statistics show that the use of PVC and polyethylene (PE) products in the domestic medical plastic market is the largest, of which medical products made of PVC as raw materials rank first in the market consumption ratio. Including blood transfusion bag, infusion bag, disposable intravenous infusion tube, peritoneal dialysis bag, all kinds of medical cannula, disposable identification bracelet, disposable nasal oxygen tube, etc.

Magnesium chloride hexahydrate is divided into food grade, industrial grade and aquaculture feed grade according to its different applications. 

PVC plastic is a commonly used plastic, and many products are currently obtained by processing PVC plastic. However, many people worry that PVC plastic will be toxic and affect health, so PVC plastic is toxic in that case? Why does PVC plastic turn yellow? Today, we will introduce in detail the "PVC plastic in which case is toxic, why does it turn yellow?"

First of all, protective wax is classified according to its application. Secondly, PE wax, paraffin wax and microcrystalline wax all can be used as protective wax.

PVC modifiers can be divided into 6 groups according to their functions and modification characteristics for glassy amorphous PVC modifiers

The impact resistance of MBS resin is better than EVA, but worse than ACR, CPE and ABS. MBS is close to ABS in weather resistance, but inferior to the other three. In terms of light and thermal stability, MBS is close to ABS, but lower than ACR. With the CPE. It should be emphasized that the important role of MBS resin in the processing of transparent PVC resin products cannot be replaced. MBS resin can usually increase the impact strength of PVC by 5-6 times, and has little influence on tensile strength and elongation.

[Summary Description] The multilevel microphase structure of liquid crystal and polymer composite materials has a potential application prospect in the fields of nano-template, nano-printing and information anti-counterfeiting, and has been widely concerned by researchers in recent years.

PVC resin has a number of double bonds and unstable structure, which is easy to break under the damage of light and oxygen, which causes discoloration of the product. The unstable structure of different resins is not the same, that is, the stability is not the same, so choose A resin excellent in stability and weather resistance is a prerequisite for maintaining the weather resistance of the product.
