FAQ

How many kinds of plastic raw materials are there? How to distinguish them?
Classification, composition and characteristics of plasticsPlastic is a synthetic polymer material widely used, in our daily life. From the plastic products meet the eye everywhere after we get up to use the toilet articles, the breakfast dishes, to work with the rest of the stationery, with cushions, mattresses, and TV, washing machine, computer shell, and the night bring us all the other light lamps......
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
What is the plastic bag made of?
The main raw material of plastics is oil and natural gas, that is, carbon hydrogen compounds. First, the appropriate macromolecular components in petroleum and natural gas are extracted, first split into monomers, and then polymerized into polymers to become plastic
Plastic raw materials, why LDPE and LLDPE?
LDPE is low density polyethylene, that is, high pressure material; LLDPE is linear material.
PE plastic bellows raw material formula (PE and PP ratio, as well as other filling)?
PP and PE plastic corrugated pipe in the role of the following two: 1, PP material can reduce the production of pipe, HDPE than PP pipe grade market sales price higher, the production of HDPE pipeline adding appropriate amount of PP, for the reduction of raw materials
Plastic PPT30S add what material will increase hardness?
Commonly used talc and calcium carbonate increase the flexural modulus rather than the surface hardness. To increase surface hardness, a nucleating agent can be used. Moreover, talc and calcium carbonate can not be added to the injection molding, you must use the pumping equipment.
What are the APP of plastic raw materials?
Thermoplastic engineering plastics (polyamides, polycarbonates, POM, PET, PBT and others)
What's the shell of the relay? What exactly is plastic?
In thermoplastic resins, the molecular chains of resins are linear or branched, with no chemical bonds between the chains, and soften the flow when heated. The process of cooling hardens is a physical change. The first heating thermosetting plastics can be softening, heated to a certain temperature, chemical reaction and curing a chain to harden, this change is irreversible, then again, when heated, can no longer become soft flowing.
