Product Description:


Molecular Formular : C24H38O4
Molecular weight : 390.57
CAS No.:117-81-7
H.S Code : 2917.3200.00
EINECS No.: 204-211-0
Characteristics : Colorless transparent oily liquid, slight odor.

Processing : Injection Moulding

Application : It is one of the most extensively used plasticizers in plastics processing. It has comprehensive properties, such as high plasticizing efficiency, low volatility, UV-resisting property, water-extracting proof, cold-resisting property, and also good softness and electric property. As a fine main plasticizer, it is extensively used in processing polyvinyl choride and ethylcellulose resins to produce plastic film, imitation leather, electric wire, cable wearer, sheet, planet, mould plastic products and. Used in nitrocellulose paints, it can make the ethylcellu lose more elastic and more strong in extracting tension. It can be used as a softening agent of synthetic rubber, such as to make the product easier to rebound and harder to undergo form change under pressure, without affecting of the plastics.

Q:What are the raw materials for producing plastic bowls and cups?
PE, the name at noon is polyethylene. Insoluble in water, slightly soluble in hydrocarbons, toluene, etc.. Resistance to most acid and alkali erosion, water absorption is small, at low temperatures can still maintain flexibility, high electrical insulation. Plastic cups are basically made of PE. Maybe it's because the cup doesn't have the higher requirements of the bowl, and PE is generally cheaper than PP.
Q:What material is best for plastic gears?
The most commonly used is the POM. It can be made of carbon fiber reinforced, more stable size, of course, can also use high-end engineering plastics, such as: PEEK, SP-1, Teflon, LR, and so on. For different occasions, different characteristics of the use of choice
Q:What do you mean by grade 1, class two or class three in plastic?
Three grade material refers to the raw material has been used two times or more times, the processing of particles, and its elasticity, toughness and other aspects are not very good.
Q:What's the difference between recycled plastic bucket and plastic bucket made of raw material?
The easiest way to do this is to press hard, see flexibility and bounce back. You can also cut off a small piece with a knife, lost in the water, can float is generally the new material is recycled sink. If PE is the plastic bucket, the recycled material is usually porcelain white, and the raw material should be translucent.
Q:What is plastic film material?
The material is plastic particles. Polyethylene film is used for polyethylene particles; polypropylene film is polypropylene particles. Some of the films are blown out of film blowing machines; some are cast films and pressed out of the machine.
Q:What are the heavy bags in the plastic material?
(polypropylene) English Name: Polypropylene, PP plastic concept, proportion polypropylene, also includes propylene and a small amount of ethylene copolymer. PP granular material is natural, cylindrical particles, smooth particles
Q:What can recycled plastics do?
Plastic has good processability, easy to shape, such as: blow, extrusion, pressure, easy cutting, easy welding. In daily life there are many plastics can granulation, such as waste food bags, sandals, wire, plate, agricultural film, pipe, barrels, pots, and packaged with all kinds of waste plastic products can be repeatedly processing, production of plastic raw materials, through special process and formula for making machine parts and components; the system can be used for water, farm machinery, packing bag, cement bag;
Q:What is the difference between ABS plastic raw materials and recycled materials? Or how to distinguish between raw materials and recycled materials?
1. recycled material is not natural (ABS is yellow).2. non black pellets with black spots are recycled.3. the impurity in the aggregate is the recycled material.4. of the voids in the pellets are recycled.5. do MFI test, the result is more than 10% of indicators are recycled material.6., feed heating, smell, smoke, melting temperature is low, fast flow is recycled material.
Q:What raw material (HDPE) made of plastic bags, high transparency, good sense of light master?
The plastic we usually use is not a pure substance. It is made up of many materials. The polymer (or resin) is the main component of plastic, in addition, in order to improve the performance of plastics, but also add various auxiliary materials in the polymer, such as filler, plasticizer, stabilizer, lubricant, coloring agent, can become the good performance of plastic.
Q:What material do you need for plastic film? Do you use this material?
Plastic bags, quality, food grade requirements, the use of brand new HDPE (low pressure polyethylene).
