POE toughened masterbatch granulator

& Toughening masterbatch granulator and: have certain mutual substitution in terms of toughening effect. In general toughening applications, many manufacturers mainly consider cost factors to choose them. In terms of toughening effect, it is generally slightly better. Some of the different properties of PTFE and PTFE are suitable for products with other special performance requirements in addition to toughening. In film applications, it has better barrier properties, while generally there is no printing and dyeing effect that can be improved, but it will reduce the aging resistance, while the unit density with good aging resistance and excellent heat resistance and cold resistance is smaller, Inexpensive for volume.
High rubber powder: chemical structure styrene, acrylonitrile butadiene rubber, core-shell polymer.
General purpose
. For general-purpose grade, it can be directly blended and granulated. It is recommended to use Daqing and Guoheng because their nitrile content and high rubber powder are the best matched and comply with the similar compatibility rules. The blending ratio is generally ~:~, which can achieve the ideal physical properties (other additives are added according to normal proportions, internal lubricant is ~~, external lubricant is ~~, and antioxidant is ~~). The emulsion grafting bulk blending method commonly used by domestic B manufacturers requires B rubber powder to be obtained and blended. Therefore, it is not surprising that there are high rubber powders of Daqing, Xinhu, Guoheng, Taihua and other brands on the market. Because B high rubber powder is originally its upstream product, it can be continued to be used for general use or sold as finished products.
To make modified B products, it is the same as making general B. B high rubber powder needs to be mixed. The only difference is that other additives are added while mixing. For example, flame retardant and Flame retardant synergist, (Typical formula: B powder %%, , flame retardant, auxiliary agent %%) To make heat-resistant B, additional heat-resistant components need to be added to make glass fiber-containing B, additional glass fiber filler is added.
Make B alloy products, such as C/B alloy, /B alloy, /B alloy, B/B alloy. The so-called alloy material is nothing more than the physical blending of two or more materials in a certain proportion. , learn from each other's strengths and weaknesses to obtain materials with better comprehensive properties. As for the B component, it also needs to be blended with high rubber powder. The only difference is that the proportion in the alloy is smaller. For example, when producing C alloy, high rubber powder generally requires 100 parts (typically Formula: B powder %%, auxiliaries %%), among the performance indicators, the impact reaches /, the heat deformation temperature is ℃, and the Rockwell hardness is around 10%.
. Toughened B regrind, C/B regrind, etc. Regardless of the new material regrind, its impact strength is provided by rubber powder. Due to the aging of butadiene in the rubber, the impact strength of the regrind has dropped significantly. Its impact strength can be enhanced by adding new rubber powder.
