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:What material is plastic bag made of?
Polyethylene (Polyethylene, PE), referred to as PE. It is a high molecular organic compound which is made up of ethylene. Polyethylene is recognized as the best food for contact with food in the world. Non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture-proof, anti - oxygen, acid, alkali, air tightness, heat sealing and other outstanding performance. Known as "plastic flowers" laudatory title. It is the most important and most important material in plastic packaging and printing.
Q:What is the difference between EPS plastic particles and PS? What materials are represented?
EPS is a foaming agent that is used to make foam, which is the white foam that is packed in the TV and refrigerator.
Q:What is the raw material used in the production of plastic products?
Cling film, plastic film are such materials, heat resistance is not strong. Usually qualified PE cling film will appear hot when the temperature exceeds 110 degrees, and will leave some plastic preparations which can not be decomposed by human body. And wrapped with plastic wrap food heating, food grease is easy to preserve the harmful substances dissolved in the film. Therefore, the food into the microwave oven before, to remove the cling film wrapped.
Q:What material is good for plastic bellows?
In the cases to recommend the use of PE (polyethylene) bellowsNo oxidizing acids, no environmental oils, vegetable oils, mineral oils, no organic solvents such as aliphatic hydrocarbons, aromatic hydrocarbons, ketones, esters, etc..Mainly used in the temperature range of -40 to 80 degrees Celsius environment; used in automobiles, motorcycles and other motor vehicle wire harness sheath; also used for household appliances, precision machine tools and other equipment wiring wire sheath.
Q:What raw materials do plastic color printing plants use?
Mainly plastic film and ink, the film is generally in accordance with the nature and requirements of products such as PVC film, POF film
Q:What is the hardness of PAEK+30%GF plastic material?
Mohs hardness is mainly used in mineral classification. The Mohs scale from I to 10. the scratch resistance increasing (such as talc Mohs hardness is I, the diamond is 10), namely each scale corresponding to the Mohs material can be scraped traces in the previous stage of material. According to the Mohs hardness can determine the scratch resistance between contact with objects in the use of Engineering plastics.Engineering plastics Mohs hardness is between 2 and 3.
Q:How to test plastic raw materials?
Sample appearance quality. The plastic raw material is produced according to the normal production process, and the appearance quality of 10~20 parts is observed. The sample product shall not be cracked, deformed, foamed, broken, expanded or shrunk, and other defects that affect appearance. Smooth surface and clear surface.
Q:What is the specific material for plastic pallets?
Polyethylene (HDPE) has excellent impact resistance and cold resistance, and it can resist environmental stress cracking. Excellent chemical stability, good oil resistance. Water absorption and tiny, low permeability, organic vapor transmission rate is larger. Electrical insulation is good, in all frequency range, dielectric properties are extremely excellent.
Q:PE plastic bellows raw material formula (PE and PP ratio, as well as other filling)?
PE bellows formulations generally include the main resin, additives and fillers, in which the resin polymer in the infrared spectrum of the difference, the plastic material can be judged by analysis.
In the past years, We have get more and more experiences in sales market and new items developments, Which shall be the great advantages for us to get more achievements in the international market.
