1.Essential difference Physical foaming is to use physical principles for foaming, such as dissolving gas or liquid in plastic, and then making it expand or vaporize. Chemical foaming is a method to make the plastic melt full of bubbles by using the specially added chemical foaming agent to decompose by heat or chemical reaction between

By means of chemical reaction, several maleic anhydride molecules are connected on the polyethylene molecular chain, so that the product not only has the good processability and other excellent properties of polyethylene, but also has the re reactivity and strong polarity of maleic anhydride polar molecules, which is conducive to use as coupling agent and

1.The reason why compatibilizer is called Maleic Anhydride Grafted Compatibilizer is that it can improve the compatibility between polymer and alloy (this coupling agent is not good), and improve the compatibility and combination between resin and filler. For example, for PC / ABS alloy, it is useless to add maleic anhydride graft compatibilizer and coupling

There are many advantages of adding Physical Foaming Nucleating Agent in polypropylene modification. Nucleating agent can promote the crystallization rate of melt, obviously improve the mechanical properties and processing properties of polypropylene products, and benefit the aging resistance and optical properties of products. The functions of these nucleating agents are summarized into 5 points and

Qingming Festival, also known as the outing Festival, Xingqing Festival, March Festival and ancestor worship Festival, is held at the intersection of mid spring and late spring. Qingming Festival originated from the ancient ancestor belief and spring festival rituals and customs. It has both natural and human connotations. It is not only a natural solar

The Single Screw Extruder needs to be equipped with a device to detect the pressure in the middle section, head and other places. It is better to take the extrusion pressure as the reference parameter of the whole production line. In the design of the screw, BM section can be added in the front section

The physical foaming method has a series of advantages and benefits, such as high foaming degree, low dielectric constant ε and dielectric loss angle TG δ, reducing cable attenuation, good foaming uniformity, fine foaming hole, airtight, high production efficiency, etc. it adapts to the requirements of higher transmission frequency and wider transmission cable bandwidth in

April 1st is a traditional Western Folk Festival, April Fool’s day, also known as April Fool’s day. There are different opinions on its origin: one view holds that the custom originated from the “hermeneutic Festival” in India. The festival stipulates that on the festival day of March 31 every year, couples fool and cheat each

The Micro-injection metering pump has a wide range of distribution capacity and flow rate. The factory set discontinuous pulse distribution range of micropump (micro metering pump, electromagnetic diaphragm pump) is 8 to 250 μ L, the pulse frequency of Zui small model and model can reach 2.0 Hz and 1.6 Hz respectively, and the flow
