- Q: What plastic material has great impact resistance?
- The ability of metal materials, machinery parts and components to resist impact damage is called impact strength.
- Q: What is the difference between PPA plastic raw material and PP?
- PPA is a high temperature nylon, generally used in the automotive industry and the electrical and electronic industry, it has the characteristics of high temperature resistant nylon, but also much higher than nylon, that is to say in the high temperature working environment inside it will be more excellent performance than ordinary nylon, longer service life. At present, the high temperature nylon base material on the market is basically nylon 46, nylon, 6T, 9T and so on.
- Q: What is the plastic basin made of?
- The raw material is PP and PE, the raw material price is more than 10000, and some can be recycled at around 5000.
- Q: Main ingredients and formulations of PPR tubes
- The main ingredient of PPR tube is polypropylene. The formula is simple. It is added color masterbatch. Suggest not to add any calcium powder and so on.
- Q: Is plastic bucket and plastic bottle the same raw material?
- When the number of the triangle in the bottom of the barrel is "1", the main component of this kind of plastic bucket is polyethylene terephthalate (polyester), which is often called PET. The melting point of this kind of plastic barrel is high, but the heat resistance can only reach 70 degrees centigrade, and it is easy to deform. When the temperature of the plastic barrel is higher than that of the plastic bucket, the possibility of dissolving harmful substances in the plastic barrel is increased, and the material such as wine, oil and the like can be easily twisted and contracted. As China has traditionally been thrifty, people tend to reuse plastic buckets. However, this kind of plastic barrels of repeated use, may release carcinogenic DEHP, if such liquid plastic barrel by people drinking, will may be suffering from cancer, also has toxicity to male testis, its harm should not be overlooked.
- Q: What are the main biodegradable plastic bags made of?
- The degradable plastic bags made of polyethylene and starch, but this can only be degradable plastic plastic degradation into smaller chunks of plastic, plastic compositions did not completely disappear, so its degradation is limited.
- Q: Characteristics and uses of CA plastics
- Because of its characteristics and quality of different varieties are different, generally use as general plastics, in addition to avoid the use of related in food packaging, medical devices and health fields, the other is used. For example, car interior and exterior shell, household appliances and other daily necessities, mainly low price.
- Q: What are the properties of plastic material PS? What are the advantages and disadvantages?
- Amorphous material, moisture absorption is small, do not have to be fully dry, not easy to break down, but the coefficient of thermal expansion is large, easy to produce internal stress. Good liquidity, can be used screw or plunger injection molding machine
- Q: What does MFI mean in PC material?
- MFI- melt flow index, also known as the melt flow rate (MFR), it was determined at a given shear stress (with applied load) and temperature, melt flow properties of materials (measured by g/10min).
- Q: Is plastic raw material rubber?
- Raw materials are polymers of polymers such as polypropylene. Is generally from the fossil raw materials inside the extraction after polymerization together. A series of plastic refers to the resin as the main component, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials. To put it simply, the oil was extracted and finally made into plastic, rubber and plastic
