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.

High quality Dioctyl phthalate DOP

Q:Plastic raw materials, why LDPE and LLDPE?: LDPE is low density polyethylene, that is, high pressure material; LLDPE is linear material.

Q:How many kinds of plastic raw materials are there? How to distinguish them?: According to the nature of the plastic after heating, it is divided into thermoplastic and thermosetting plasticsThermoplastic molecular structures are linear structure, softening or melting when heated, plastic into certain shape, after cooling and hardening. When heated to a certain extent to soften after cooling and harden, this process can be repeated several times. Such as polyvinyl chloride, polyethylene, polystyrene and other thermoplastic. Plastic molding process is relatively simple, can continuous production, and has very high mechanical strength, so it is developing very quickly.The molecular structure of thermosetting plastics is the body structure, softening also occurs in heated, can plastic into a certain shape, but is heated to a certain extent or amount of curing agent, hardened stereotypes, re heating become soft and will not change shape. The thermosetting plastic processing molding after heating no softening, and therefore can not be recovered then, such as phenolic, amino plastics, resin and other plastic. These are thermosetting plastic molding process is more complex, so the continuous production is difficult, but its good heat resistance, not easy to deformation, and the price is relatively low.

Q:What are the APP of plastic raw materials?: Thermosetting plastics (phenolics, epoxy resins, unsaturated polyesters, polyurethanes, silicones, amino resins, etc.);

Q:Dissolve in 0.3 of the LDPE plastic raw materials what?: LLDPE, which was industrialized by Union Carbide in 1970s, represents a major change in polyethylene catalyst and process technology, which has significantly expanded the range of polyethylene products. LLDPE with coordination catalyst instead of free radical initiator, and with low cost low pressure gas phase polymerization reactor to replace the high cost, in a relatively short period of time, with its excellent performance and low cost, has replaced the LDPE in many areas. At present, LLDPE permeates almost all traditional polyethylene market, including film, molding, tubing and wire and cable.

Q:What are the common raw materials used in plastic bottles? What are the main features?: PE bottles and PP bottles are similar, toughness is better than PP, but rigidity and heat resistance are poor, solvent resistance is good, plastic soy sauce bottles seem to be PE, temporary loading a small amount of wine, kerosene will do.

Q:Will plastic raw materials (such as PET, PP, etc.) be made of non-woven fabrics, will certainly contain BPA?: BPA doesn't come out of thin air. PC uses BPA as raw material, so it comes with a little bit. Most plastics do not contain bpa. If you need to verify, you can test it and then ask the supplier to verify it. The electronic industry has done so, every level to find upstream suppliers signed a certificate of protection. We should ensure that mobile phone materials do not contain BPA, plasticizers and more than 150 substances.

Q:I do PA, PC, PP and other plastic raw materials can be used in the eye frame and lens it: In general, the lenses of PC need to be covered with scratch resistant protective films, which will be sufficient for better aging, and most lenses for children.

Q:What is the raw material for producing high temperature polyethylene plastic bags?: In the process, 2% montmorillonite can be added, which can significantly improve the thermal stability and tensile properties. For specific methods, please refer to the relevant literature.

Q:What kind of material is the plastic bag commonly used in supermarkets now?: Another is PP or OPP, which contains bread and crackers. The material is smooth and very transparent, but the tightness is not very good and there is no tension.

Q:Main ingredients and formulations of PPR tubes: PP-R (polypropylene, random) tubes are also called type three polypropylene tubes and also called random copolymerized polypropylene tubes or PPR tubes. The main component is polypropylene three. The formula is different for each manufacturer. This ratio requires manufacturers to do experiments many times before they can be certain.
