PE plastic bellows raw material formula (PE and PP ratio, as well as other filling)?
- The additives are mostly organic additives, and they are usually analyzed by infrared, nuclear magnetic resonance and mass spectrometry. Fillers are mostly calcium carbonate, kaolin and other fillers, play a role in strengthening and reducing costs, and can be qualitatively and quantitatively analyzed by thermogravimetric analysis and fluorescence spectroscopy. After sample pretreatment, a single component, for unknown components need to go through a variety of instruments integrated spectrum, the final reduction formula, get the whole component analysis report.s
What is the hardness of PAEK+30%GF plastic material?
- Polypropylene plastic (PP) hardness is Rockwell hardness 48. General plastics Rockwell hardness, Brinell hardness and Rockwell hardness measurement, not with Mohs hardness measurement. The hardness of nails is not measured, so it is difficult to compare with the data, I think the hardness should be quite.s
What is the raw material used in the production of plastic products?
- Common mineral water bottles and carbonated beverage bottles are made of this kind of material which can not be recycled or hot water. Its heat-resistant temperature is only 70 degrees, only suitable for warm drinks or cold drinks, high temperature liquid or heating, easy to deformation, will dissolve the harmful substances. The scientists also found that the plastic could release carcinogens in 10 months. Therefore, when the beverage bottle is used up, it should be thrown away. It should not be used as a drinking cup or used as a storage container to hold other foods, so as not to cause health problems.s
Can PE material be used as food grade plastic?
- Yes, of course, but the raw material suppliers have already divided the ingredients into food grade, and they will be used in non food occasions to contain substances harmful to the bodyFor human health, please choose food grade PE materials, and note that the highest temperature can not exceed the manufacturer's maximum limit, otherwise the material will appear unstable, resulting in harmful substancess
What raw material (HDPE) made of plastic bags, high transparency, good sense of light master?
- Fillers, also called fillers, can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood powder to phenolic resin can greatly reduce the cost, and make phenolic plastic one of the cheapest plastics, and can also significantly improve the mechanical strength. Packing can be divided into two kinds of organic fillers and inorganic filler, the former such as wood powder, rags, paper and all kinds of fabric, the latter such as glass fiber, diatomite, asbestos, carbon black.s
Plastic pipe gas temperature 150 degrees, plastic pipe surface problems?
- Plastic pipe is usually plastic resin as raw material, adding stabilizers, lubricants, etc., to "plastic" method in the pipe mill by extrusion processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering. Mainly used for building construction of the water supply system, piping, drainage, exhaust and sewage sanitary pipe, underground drainage pipe system, storm pipe and wire installation supporting the use of threading tubes, and so on.s
What are the raw materials made of modified plastics?
- In order to reduce costs, improve performance and meet different needs, plastics are often modified to suit a variety of practical requirements. Commonly used methods are mainly:1. filling modification, adding a certain amount of filler in plastic is an important way to reduce plastic prices and improve performance. Such as phenolic resin filled with wood and paper made of bakelite practical material, overcomes the weakness of crisp.2. blends of two or more polymers with similar properties and two or more polymers are blended in a certain proportion to make polymer blends.3. copolymerization of two or more than two kinds of monomer polymerization of a copolymer of ethylene propylene rubber, such as copolymerization of ethylene and propylene has a good elasticity; acrylonitrile, butadiene and styrene copolymer obtained with ABS resin.s
What kind of plastic material is used for medical instruments?
- You need to add various additives in plastics processing or modification process, such as in the PVC medical products in the amount of the plasticizer is as high as 30 - 60%, so as far as possible the use of non-toxic additives, long-term use to prevent or reduce the additive precipitation, so as not to affect the product performance and the therapeutic effect;s
