Abbreviation code of plastic resin of plastic raw material physical properties

The meaning of the representation is as follows:

1. Polyester ———01-PET (PET bottle) such as: mineral water bottles, carbonated drink bottles.

2. High-density polyethylene - 02-HDPE such as: cleaning products, bath products.

3. PVC ———03—PVC such as: some decorative materials.

4. Low-density polyethylene - 04-LDPE such as: plastic wrap, plastic film, etc.

5. Polypropylene———05-pp (can withstand temperatures above 100 degrees) such as: microwave oven lunch box.

6. Polystyrene———06-ps (heat-resistant 60-70 degrees, hot drinks will produce toxins, and styrene will be released when burning) Such as: bowls of instant noodle boxes, fast food boxes.

7. Other plastics**—— 07—others such as: kettles, cups, bottles.

Precautions should be taken when using plastic products:

1. To understand the performance of the plastic products used, you can look at the logo at the bottom of the product, and you can know the material of the plastic through the logo.

2. Most plastics are not resistant to high temperatures, so try not to use plastic products to heat at high temperatures.

3. It is best not to use plastic products to contain oil, vinegar, oil, etc., for example, if the vinegar is stored for a long time, it may make the plastic swell, thus producing harmful substances to the human body.

4. Pay attention to maintenance when using plastic products, do not expose them to the sun, try not to let them rain, and dry them as soon as possible if they are rained.

Hello, I will answer for you about the physical properties of plastic raw materials, I believe that many friends do not know, now let's take a look at it! 1. ABS plasticized stool grinding name: C. <>

1. Chemical name of ABS plastic: acrylonitrile-butadiene-styrene copolymer, full name in English: Acrylonitrile butadiene styreneabs plastic physical properties:

ABS plastic specific gravity: grams cubic centimeters, molding shrinkage: , molding temperature:

200-240, drying conditions: 80-90 2 hours ABS plastic features: good comprehensive performance, high impact strength, chemical stability, good electrical properties; 2. It has good weldability with 372 plexiglass, and is made into two-color plastic parts, and can be chrome-plated and painted on the surface; 3. There are high impact resistance, high heat resistance, flame retardant, reinforced, transparent and other grades; 4. The fluidity is a little worse than HIPS, better than PMMA, PC, etc., and the flexibility is good.

2. The use of ABS plastic: suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and telecommunication parts.

The English abbreviation for "plastic material" is plastic material.

According to the scope of application, plastic materials can be divided into: general plastics, engineering plastics, and special engineering plastics.

General-purpose plastics, a type of plastic with a particularly large output, a wide range of uses, and a low grade. The main ones include PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride), PS (polystyrene), PF (phenolic plastic) and amino plastics. Their total production accounts for more than 75% of the total production of plastics.

Many of the products that people use in their daily lives are made from these general-purpose plastics.

Engineering plastics, long-term use temperature at 100-150 degrees. It can withstand a certain external force, has good mechanical properties and dimensional stability, and can maintain its excellent properties at high and low temperatures, and can be used as a plastic for engineering structural parts. Because of their high mechanical strength or special properties such as high temperature resistance, corrosion resistance, radiation resistance, etc., they can replace metal as some unloading components or other special purposes.

Special engineering plastics, long-term use temperature of more than 150 degrees. Plastics with high mechanical strength and heat temperature resistance, or with special functions and can meet the requirements of special applications. According to whether the polymer is cross-linked or not, it can be divided into cross-linked type and fee cross-linked special engineering plastics.

The physical properties of plastic raw materials are a collection of plastic raw materials, which brings together detailed information on the physical properties of plastic raw materials.
