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 is Ms plastic material?
Transparent polymers were synthesized from methyl methacrylate (MMA) and styrene (SM) as the main raw materials.
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:How to identify the proportion of nozzle material in plastic?
The melt index is detected by a melt flow rate analyzer. If the nozzle is added, the melt index will generally increase
Q:What is the raw material used in the production of plastic products?
Bearing cleaning supplies, plastic containers and bath products currently used in supermarkets and shopping malls in the plastic bag is made of this material, can resist high temperature of 110 DEG C, indicating the food use of plastic bags can be used for holding food. Bearing cleaning supplies, plastic containers and bath products can be repeatedly used carefully after cleaning, but these containers are usually not good cleaning, easy residual cleaning supplies, become a breeding ground for bacteria, it is better not to use circulation cleaning is not thorough so.
Q:What are the plastic raw materials?
Plastic raw material is a kind of polymer (polymer), also known as macromolecule or macromolecule, also is commonly known as plastic or resin. The so-called plastic raw material, in fact, it is a kind of [synthetic resin], the shape of the natural resin [pine resin] similar, but because of the chemical strength of the synthesis, and is called plastic.
Q:What is the difference between PA66 and PA6 plastic raw materials? Differences in price, color, performance, etc
Both are nylon series. What about the price, PA66? More expensive. The performance is probably about the same
Q:What are the raw materials for vest plastic bags?
Polyethylene (Polyethylene, PE), referred to as PE. It is a high molecular organic compound which is made up of ethylene. Polyethylene is recognized as the best food for contact with food in the world. Non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture-proof, anti - oxygen, acid, alkali, air tightness, heat sealing and other outstanding performance. Known as "plastic flowers" laudatory title. It is the most important and most important material in plastic packaging and printing.
Q:What kind of material is the plastic bag commonly used in supermarkets now?
1. HDPE is a shopping bag for supermarkets. It feels cool and hard to use. Do not add color, the bag is very dim.2. low density polyethylene, used for packaged food, feels soft and transparent.
Q:What are the properties of plastic material PS? What are the advantages and disadvantages?
The parameters of PS plastic (polystyrene) English Name: Polystyrene weight: 1.05 g / cm3 molding shrinkage rate: temperature: 170-250 degrees 0.6-0.8% molding material properties of electrical insulation (especially high-frequency insulation) excellent, colorless and transparent, light transmittance after organic glass, color of water resistance, good chemical stability, strength, but brittle that is easy to produce stress cracking, no resistance to benzene. Gasoline and other organic solvents. Suitable for production of transparent insulation. Trim and chemical equipment. Optical instrument parts forming performance.
Q:What kind of plastic material is used for medical instruments?
According to the use requirements of medical plastics, it is often necessary to make products with surface hydrophilicity, anti coagulation, radiation sterilization and other special functions.
