Q:PP plastic stool surface with those raw materials, what is the ratio?
PP is crystalline polymer. PP is the most common plastic, and the density is only 0.91g/cm3 (smaller than water).
Q:Plastic PPT30S add what material will increase hardness?
In general, this material will be grafted with PP-G, POE, increase the impact, plus stone powder, glass fiber, mica powder, increase hardness.
Q:What's the shell of the relay? What exactly is plastic?
It is by virtue of this characteristic of molding, the use of the first heating of the plastic flow, under pressure filled cavity, and then solidified into a shape and size of the product. Thermosetting resins are linear or branched before curing, forming a chemical bond between the molecular chains after curing, becoming a network of three degrees, not only without melting, but also insoluble in solvents. Bakelite, formaldehyde, melamine, formaldehyde, epoxy, unsaturated polyester and silicone plastics are all thermosetting plastics. Mainly used for heat insulation, abrasion resistance, insulation, high voltage resistance in the harsh environment of the use of plastic, mostly thermosetting plastic, most commonly used should be wok, pot handle and high and low voltage appliances.. Commonly used thermosetting plastics are phenolic resin, urea formaldehyde resin, melamine resin, unsaturated polyester resin, epoxy resin, silicone resin, polyurethane and so on
Q:What is the raw material for producing corn starch plastic film?
At present, China's maize production in 1.31.5 million tons, only 1/10 of the corn crop is processed into starch, used in the textile industry, paper industry, food industry, medical industry and other fields, the total amount of nearly 10 million tons of starch (including corn starch close to 9 million tons; 420 thousand tons of cassava starch, potato starch, 240 thousand tons).
Q:The difference between resin and plastics
Plastic refers to the resin (or in the process of using monomer polymerization) as the main ingredient, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials, but also can be said to be material with resin as the main raw material and has plasticity and product. Plastic generally refers to finished products, such as plastic cups, plastic bowls and so on.
Q:Plastic raw materials, why LDPE and LLDPE?
LDPE is a low density polyethylene with a large number of branched structures. The molecular structure is lack of regularity, so the crystallinity of LDPE is small, 65%~75%, and the density is low, 0.91~0.93 grams / cubic centimeter. LLDPE is a linear low density polyethylene. Its molecular structure is linear, branched less, branched short, and its density is similar to that of LDPE. Its physical and mechanical properties are better than those of LDPE.
Q:What are the raw materials of plastics made of?
Synthetic resin refers to coal, petroleum, natural gas, calcium carbide and some agricultural products as the main raw material, the low molecular weight compounds prepared firstly has certain synthetic conditions (monomer), and then through chemical and physical methods for the synthesis of high molecular compound. The characteristics of this kind of compounds similar to natural resin (such as rosin, shellac, amber, etc.), but the performance and more superior than the natural resin.
Q:What are the raw materials for vest plastic bags?
Shrink film (Shrinkfilm) is a thermoplastic film that is stretched in production, directed, and contracted by hot air treatment or infrared radiation 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.
Q:What is plastic material E-PET?
With the prevalence of the hardware industry, more industry technology is dazzling, and the technology that we know may not be even longer, so here we are talking about what is the real PET plastic.Polybutylene terephthalate mainly consists of polyethylene terephthalate two (PET) and polybutylene terephthalate (two) (PBT).PET is highly symmetrical and has certain crystalline orientation ability, so it has high film forming ability and plasticity. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent wear resistance, friction and dimensional stability, and electrical insulation. PET bottles are widely used because of their high strength, good transparency, non-toxic, impermeable, light quality and high production efficiency. PBT and PET molecular chain structure similar, most of the same nature, but the main chain from two methylene into four, so the molecules are more supple, processing performance is better.
Q:What kind of plastic material is used for medical instruments?
Plastic) inevitable in the process of polymerization reactor, to come into contact with the metal catalyst. Often contain trace metal ions, according to the national standard of medical plastic, residues are clearly defined for zinc, lead, cadmium, copper, barium, tin and other metal ions;
