Q:What is the material of plastic dip?

Immersion is a plastic coating process, that is, the plastic coating on the substrate (usually metal), such as: our daily clothes racks, pliers handle, scissors on the rubber sleeve, handrails and so on. According to whether need to be heated into hot dip and cold plastic raw materials, in accordance with the dip to points can be divided into liquid dip and dip powder.

Q:Low pressure plastic raw materials in the process of blowing the two sides of the fold, how to deal with?

Blow up ratio of transverse expansion ratio of the film, is actually on the orientation of the transverse tensile film, tension will have a certain degree of plastic molecules, the blowing ratio is increased, thereby improve the lateral strength of thin films.

Q:What is plastic film material?

You should first say what type of plastic film you are going to make. You should make a bag or make a plastic wrap. The type is different. You should see what determines what material to use, and the plastic film is also divided into many kinds

Q:What does plastic material include?

The main raw material of plastics is oil and natural gas, that is, carbon hydrogen compounds. First, the appropriate large molecules in petroleum and natural gas are extracted, first split into monomers, and then polymerized into polymers to become plastic.

Q:What are the main biodegradable plastic bags made of?

Biodegradable plastics(1) natural polymer modification method. Starch, cellulose, chitin, lignin, seaweed and other natural polymers as raw materials, through chemical modification and copolymerization method, these molecules were modified to synthesize biodegradable plastics.(2) chemical synthesis. The simulation of natural polymer structure, starting from simple water molecules, in the polymer chain of plastic with active groups such as amide, peptidyl, ester compounds containing these radicals, similar to natural protein structure, fragments of grease, easily biodegradable.(3) microbial fermentation, many microorganisms can take some organic substances as carbon source, through metabolism, secrete, produce polyester polymer, these molecules are easy to degrade, and can be further recycled.

Q:I'd like to know what PP plastic material is PP plastic raw materials cleaning can not use ultrasonic cleaning machine to wash it?

However, for some occasions, water can be used instead of organic solvent to clean the acid and alkali. Thus compared with other various cleaning methods, ultrasonic cleaning machine shows great advantages, in particular, in the group of professional production enterprises, has gradually replaced the traditional ultrasonic cleaning machine, cleaning, washing, washing pressure vibration cleaning and steam cleaning process.

Q:What material is plastic bag made of?

Shrinkfilm-- shrink film (Shrinkfilm) is a thermoplastic film that is stretched during production, contracted, and subjected to thermal air treatment or infrared irradiation during use. After heat treatment, the film is wrapped tightly in the package, and the shrinkage force reaches the maximum value in the cooling stage and can be stored for a long time. LDPE-- low density polyethylene (LDPE), low density polyethylene (HDPE), or LDPE, is the most widely used plastic packaging and printing industry in many countries. The specific gravity is 0.92 ~ 0.93, and can float in water. Low crystallinity (60%), under the pressure of 1000 ~ 3000kg/C square meters of bulk polymerization of high pressure polyethylene. At 23 degrees centigrade, the density is about 0.92. It is difficult to roll forming and is suitable for tubular films. Applicable to food packaging, fiber packaging, daily necessities packaging. Degradable plastic bags mark

Q:Can PE material be used as food grade plastic?

Yes, 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 body

Q:What are the POE plastic raw materials?

POE classification of plastics raw materials:Plasticizing properties: Thermoplastics and thermosetting plastics.Divided by use: General Plastics and engineering plastics.

Q:What are the specific differences between plastics and plastics?

Plastic materials (LC plastic raw materials wholesale, high temperature resistant plastic material, PPS, LCP, PET, PA, PES plastic raw materials suppliers): the main ingredient is resin, is made of polymer resin as main ingredients into a variety of auxiliary material or adding agent, at a certain temperature, with plastic and motor can be under pressure molded into shape and maintain the same shape of material under certain conditions;
