What are polypropylene particles, polypropylene pp particles

Summary. PP particles are polypropylene particles, which can be made of petroleum, coal, PDH, methanol, propane, propylene. At present, the majority of PP made of coal and oil PP are mainly used in China, and PP particles should be called PP slices strictly speaking, but in China, the industry is used to calling PP particles, and it has been inherited.

So what are the properties of PP particles, and what are their application ranges? PP particles have less density and lighter weight, which can be used to make interior and exterior decorations, dashboards and bumpers and other products of automobiles to reduce the weight of automobiles and reduce fuel consumption. Especially in new energy vehicles, it is widely used, because the battery storage capacity of new energy vehicles is limited, and reducing the total weight of the car can effectively reduce the consumption of electricity and prolong the driving time of the car.

PP granules have a certain degree of transparency and hygiene, so they are widely used in the medical field, such as the infusion bottles and infusion tubes we use are PP granule products. Heat resistance is also an advantage of PP granules, which can be used normally at high temperatures of 100 degrees Celsius, so they can be used in maternal and child products, such as non-woven fabrics, baby bottles, toys and so on. Of course, PP particles also have many disadvantages, such as poor lightfastness and ultraviolet sensitivity, and their products are easy to embrittle if they are exposed to the sun for a long time.

And its abrasion resistance and scratch resistance are also poor, so in the application of automotive interior and exterior products, additives and fillers must be added to improve its wear resistance.

Hello, upon inquiry:

PP particles are polypropylene particles, which can be made of petroleum, coal, PDH, methanol, propane, propylene. At present, the majority of PP made of coal and oil PP are mainly used in China, and PP particles should be called PP slices strictly speaking, but in China, the industry is used to calling PP particles, and it has been inherited. So what are the properties of PP particles, and what are their application ranges?

PP particles have less density and lighter weight, which can be used to make interior and exterior decorations, dashboards and bumpers and other products of automobiles to reduce the weight of the rolling limbs of automobiles and reduce fuel consumption. In particular, Nazi is widely used in new energy vehicles, because the battery storage capacity of new energy vehicles is limited, and reducing the total weight of the car can effectively reduce the consumption of electricity and extend the driving time of the car. PP granules have a certain degree of transparency and hygiene, so they are widely used in the medical field, such as the infusion bottles and infusion tubes we use are PP granule products.

Heat resistance is also an advantage of PP granules, which can be used normally at high temperatures of 100 degrees Celsius, so they can be used in maternal and child products, such as non-woven fabrics, baby bottles, toys and so on. Of course, PP particles also have many disadvantages, such as poor lightfastness and ultraviolet sensitivity, and their products are easy to embrittle if they are exposed to the sun for a long time. And its abrasion resistance and scratch resistance are also poor, so in the application of automotive interior and exterior products, additives and fillers must be added to improve its wear resistance.

Chlorinated polyethylene pellets are a type of plastic raw material, also known as CPE pellets. It is a blend of polyethylene and chlorinating agent, which has excellent weather resistance, impact resistance, flexibility and processability.

Chlorinated polyethylene granules are commonly known to be used in the manufacture of various rubber products, plastic products, and wire and cable insulation materials. In the rubber industry, CPE can be used as a reinforcing agent or filler; In the plastics industry, CPE can be blended with PVC to improve the weather resistance and impact resistance of PVC; In terms of wire and cable insulation, CPE can be used as a secondary flame retardant.

In short, chlorinated polyethylene granules have a wide range of application prospects, and have important application value in many industries such as construction, automobiles, and Yilingliang medicine.

Summary. OK.

1. The compatibility between the two is very good, and the finished product can have a variety of properties through mixing in different proportions.

2. In what proportion is the specific mix, you can consult professional information or consult professionals.

3. Mix at will, which may produce substandard products.

Can plastic granular polypropylene be mixed with plastic granular polyethylene.

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

OK. 1. The two are very good at mixing each other, and the finished product can have a variety of properties through different proportions of mixing 2.

Hello dear! We'll be happy to answer for you. Is polyethylene and polypropylene pellet machine the sameA:

1. From the perspective of heat resistance, the heat resistance of polypropylene is higher than that of polyethylene, under normal circumstances, the melting temperature of polypropylene is about 40%-50% higher than that of polyethylene, about 160-170, so the product can be sterilized at a temperature of more than 100, and 150 is not deformed under the condition of no external force. In life, we will find that the "No. 5" polypropylene lunch box is often used to heat food in the microwave oven (the general temperature of microwave heating is 100-140), and the base plum polyethylene is not suitable for microwave oven plastic due to poor heat resistance, including lunch boxes and plastic wrap. Similarly, in the field of ordinary packaging films, polyethylene packaging bags are more suitable for use below 90, while polypropylene packaging bags are also allowed to be used at relatively high temperatures.

2. From the perspective of rigidity and tensile strength, the main characteristics of polypropylene are low density, mechanical properties are better than polyethylene, and there is a very prominent rigidity, for example, polypropylene has gradually competed with engineering plastics (PA PC), and is widely used in electronic appliances and automobiles. At the same time, due to the high tensile strength of polypropylene, and then good bending resistance, it is known as "100 folded glue", which is bent in half for 1 million times and does not turn white, which also provides clues for us to identify polypropylene products, and at the same time becomes a hidden sign for the reclassification of products.

Specific gravity, polypropylene plastic particles refer to polypropylene, and polypropylene is a polymer formed by the addition and polymerization reaction of propylene.

It can resist the corrosion of acids, alkalis, salts and a variety of organic solvents below 80, and can decompose under high temperature and oxidation. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, etc.

And because of its plasticity, polypropylene material is gradually replacing wooden products, and high strength toughness and high wear resistance have gradually replaced the mechanical function of metal. In addition, polypropylene has good grafting and composite functions, and has a huge application space in concrete, textile, packaging, agriculture, forestry and fishery.

The specific gravity of unmodified polypropylene plastic particles is about and right, and it is relatively large after modification.

Polypropylene plastic is a thermoplastic resin made from propylene polymerization. Polypropylene also includes copolymers of propylene with a small amount of ethylene. It is usually a translucent colorless solid, odorless and non-toxic.

Due to the regular structure and high crystallization, the melting point is as high as 167, heat resistance, and the products can be sterilized by steam is its outstanding advantage. density, which is the lightest general-purpose plastic. Corrosion resistance, tensile strength 30MPa, strength, rigidity and transparency are better than polyethylene.

The disadvantage is that the low temperature impact resistance is poor, and it is easy to age, but it can be overcome by modification and adding antioxidants.

The proportion of unmodified PP is around, and it is relatively large after modification.

Polyethylene can be used in film products, injection molded products, hollow products, pipe products, silk products, cable products, etc.

1. High-pressure polyethylene: more than half is used for film products, followed by pipes, injection molding products, wire wrapping, etc.

2. Medium and low, pressed polyethylene: mainly injection molded products and hollow products.

3. Ultra-high pressure polyethylene: due to the excellent comprehensive properties of ultra-high molecular weight polyethylene, it can be used as an engineering plastic.

Polyethylene Properties:

1. Polyethylene has excellent chemical stability, and is resistant to corrosion by various chemicals such as hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, potassium hydroxide, etc., at room temperature, but nitric acid and sulfuric acid have a strong destructive effect on polyethylene;

2. Polyethylene is easy to photooxidation, thermal oxidation, ozone decomposition, and easy degradation under the action of ultraviolet rays, and carbon black has excellent light shielding effect on polyethylene. After irradiation, cross-linking, chain breaking, and the formation of unsaturated groups can occur.

High-density polyethylene.
