What are the effects of powdered Nitrile rubber products on PVC soft products?

Author:

The purpose of using powdered Nitrile rubber is to make the product's wear resistance, oil resistance, aging resistance and other properties achieve the desired effect. What interesting changes will happen to the PVC soft products? Let's take a look together!

In terms of hardness, whether at room temperature or under thermal aging or oil resistance conditions, the primary and secondary order of influence of the three factors is DOP>P83>calcium carbonate. Compared to calcium carbonate, the influence of calcium carbonate is very small and not very obvious.

In terms of tensile strength, intuitively analyzed under three different experimental conditions, the ideal combination of the three factors is A1B1C2, and the degree of influence of the three factors is different. Under thermal aging and oil resistance experimental conditions, although the order of influence of the three factors is different, the overall difference is not significant. At room temperature, the order of influence of the three factors is P83>calcium carbonate>DOP, It can be seen that P83 has a relatively large impact, which is also a major factor, and is significantly affected by powdered Nitrile rubber.

In terms of elongation at break, intuitively analyzed under three different experimental conditions, it belongs to the ideal horizontal combination of three factors: A3B3C3 at room temperature, A3B3C2 under thermal aging and oil resistance conditions. The order of influence of the three factors on it is the same at room temperature and thermal aging conditions, and the uniform order is DOP calcium carbonate P83. Among them, DOP is the main factor, but in oil resistance conditions, The primary and secondary order of the three factors affecting it becomes P83>calcium carbonate>DOP, with P83 becoming the main factor.

It can be seen from the above that in the processing and production of soft PVC products, such as hose, fire hose, cable material, shoe material and other fields, in order to achieve the ideal flexibility and improve the oil resistance, cold resistance and other properties of the products, powdered Nitrile rubber plays a vital role in the formula, and its role is irreplaceable by any additives, such as CPE, ACR and some high polymer resins.
