What is the difference between rubber and plastic, and what is the difference between rubber and pla

There is a difference between rubber and plastic, rubber is much higher than plastic, the material of rubber is solid, that is to say, rubber is made of a material from the inside out, it has the effect of wear-resistant, anti-static, anti-slip and not easy to break, plastic is different, he is much worse than rubber. Now you can choose your own color on the market.

The most essential difference between rubber and plastic is divided into several large pieces:

1.From the point of view of touch feel, the feel of rubber is soft, comfortable and delicate, and has a certain elasticity, then plastic is completely inelastic and has a certain rigidity, because it is harder and more brittle.

2.From the tensile stress-strain curve, plastics exhibit a high Young's modulus in the early stage of tensile development.

The stress-strain curve has a steep rise phase, followed by yield, elongation, and fracture (brittle plastics do not undergo yield deformation, but fracture directly); Rubber, on the other hand, usually has a significant stress rise in the slight deformation phase, and then enters a gentle rise stage until the stress-strain curve is about to break.

to exhibit a zone of steep rise (usually due to strain-induced crystallization of the final stress rise). Elongation at break of rubber.

Usually much larger than plastic materials.

3.from thermodynamics.

From an angle of view, the plastic is at the glass transition temperature of the material within the temperature range of use.

below (glassy), while rubber operates in a highly elastic state above its glass transition temperature.

4.The most essential difference between plastic and rubber is that plastic deforms plastically when it is deformed, while rubber is elastically deformed. In other words, plastic is not easy to return to its original state after deformation, while rubber is relatively much easier.

The elasticity of plastic is very small, usually less than 100%, while rubber can reach 1000% or even more. In terms of plastic molding, most of the molding process is completed, and the product process is completed; After the rubber molding process is completed, a vulcanization process is required.

Hello landlord! What do you want to compare between the two?

Rubber is commonly used in automobile tires, etc., which has good wear resistance and toughness;

Plastics, on the other hand, are like washbasins, toothbrushes, mobile phone cases, etc.

There is no material comparison.

In the eyes of the industry, plastics and plastics are a thing. In the past, domestic factories were called plastic factories, while Hong Kong and Taiwan called plastic factories plastic companies. At present, in order to facilitate communication with foreign businessmen, some foreign-funded enterprises in China basically hang the "plastic" brand.

It cannot be taken literally as plastic and rubber.

Hello, rubber additives cause vulcanization derived from natural rubber. After more than 80 years of research, it was not until the 20 30s of the 20th century that with the industrialization of the basic varieties of vulcanization accelerators, 2-mercaptobenzothiazole and its hyposulfonamide derivatives and p-phenylenediamine antioxidants, rubber additives were basically formed. Plastic additives, also known as plastic additives, are some compounds that must be added to polymers (synthetic resins) when they are molded to improve their processing performance or to improve the properties of the resin itself.

The essential difference is that one is made of natural rubber vulcanization, and the other is processed by synthetic resins, and their roles are also different: plastic additives are used in a large class of additives for plastic molding products, including plasticizers, heat stabilizers, antioxidants, light stabilizers, flame retardants, foaming agents, antistatic agents, antifungal agents, colorants and brighteners (see pigments), fillers, coupling agents, lubricants, release agents, etc. The rubber additives with excellent performance can not only improve the processing performance, improve the product quality, reduce energy consumption and production costs, but also prevent aging degradation and prolong the service life.

<>The difference between plastic and rubber is as follows: 1. Different compositions Rubber is a material with elasticity, insulation, and impermeability made by extracting latex from rubber trees, rubber grass and other plants. The main component of plastic is polymer synthetic resin, that is, polymer, which is then incorporated into various auxiliary materials or additives. 2. Different characteristics: Rubber is in a high elastic state at room temperature, with high energy, and the movement of the chain segment is excited, and the conformation can be changed by the internal rotation of a single bond.

The plastic is in a glass state at room temperature, the molecular chain is in a crystalline state, and the energy is low. 3. The hardness is different, and the rubber is soft. Plastic is hard.

1. Introduction of plastics: 1) The main ingredient of plastic raw materials is resin, which is infiltrated into various auxiliary materials or additives by polymer synthetic resin as the main ingredient, which has plasticity and movement at a specific temperature and pressure, and can be molded into a certain shape, and keep the shape unchanged under certain conditions; 2) Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, and sound attenuation performance.

3) Most of the plastic raw materials are extracted from some oils, and the most familiar part of the PC material (polycarbonate plastic) is extracted from petroleum, and the PC material has a gasoline smell when burned; ABS (acrylonitrile butadiene styrene copolymer plastic) is extracted from coal, and ABS will be soot-like when burned and extinguished; POM (polyoxymethylene plastic) is extracted from natural gas, and POM will have a very smelly gas smell when it is burned. 2. Introduction of plastics: 1) Plastic raw materials are heated and compressed, and the linear expansion coefficient is much larger than that of metal; 2) The stiffness of general plastic raw materials is an order of magnitude lower than that of metal; 3) The mechanical properties of plastic raw materials will decrease significantly under long-term heating; 4) Generally, plastic raw materials are temporarily stressed at room temperature and under stress lower than their yield strength, and permanent deformation will occur 5) Plastic raw materials wholesale is very sensitive to notch damage; 6) The mechanical properties of plastic raw materials are usually much lower than those of metal, but the specific strength and specific modulus of some composite materials are higher than that of metal, and if the product design is reasonable, it will be more able to play a superiority; 7) Generally, the mechanical properties of enhanced plastic raw materials are heterogeneous; 8) Some plastic raw materials will absorb moisture and cause changes in size and performance; 9) Some plastics are flammable.

3. The difference between the two Plastic does not belong to plastic, but its main component is resin, and the main component of plastic is also resin, and the two are just the same main component, not the same thing.
