Polymerized MDI Isocyanate
Polymeric MDI is the polymerised form of methyl diphenyl diisocyanate. It is polymerised between MDI molecules through a specific chemical reaction to produce a high molecular weight polymer.The molecular structure of MDI itself gives it good stability and reactivity, making it suitable for polymerisation reactions.
Basf M20S, Huntsman 5005, WANHUA PM200,Covestro 44V20L, Kumho M-200, Tosoh MR200, Dow PAPI 27 etc
Isocyanates MDI is extensively application in most of field, such as thermal insulation rigid foam, PU coating, PU adhesive, Seepage-proofing, structure foam, Automobile bumper, high resilience etc.
With good performance such as very good fluidity, very good foaming capacity, strength well, dimension stability etc.
Typical Physical and Chemical Properties
Unit | Content | |
Appearance | - | Brownish Liquid |
Viscosity(25ºC) | (mPa·s) | 150-250 |
NCO Content | % | 30.5-32.0 |
Density (25ºC) | (g/cm3 ) | 1.220-1.250 |
Acid Content | % | ≤0.030 |
Hydrolysable Chlorin | % | ≤0.20 |
Standard Packing:Iron Drum N.W.: 250KG/Iron Drum
Can also according to your requirment to packing.
appearence: Brown transparent liquid;
boiling point (ºC): 200~208;
stability: stable. Incompatible with strong oxidizing agents, alcohols. May decompose in moist air, or on contact with water.
Since Polymerized MDI Isocyanate is a reactive chemical, reaction with atmospheric moisture happens easily and leads to the formation of insoluble ureas and carbon dioxide gas, which can result in pressure build-up in closed containers and viscosity increase of the product. Containers must therefore be absolutely dry and carefully sealed after congested with nitrogen. Containers of Polymerized MDI Isocyanate should be kept properly closed and stored indoors at ambient temperature (15-35ºC) in a well-ventilated area. Storage at low temperature (below 5ºC) may lead to some crystallization; this material must, therefore, be protected from frost.
If crystallization does occur, the material should be heated by rolling the drum in a hot air oven at 70-80ºC to melt it out, and should then be thoroughly agitated before use. Melting in a water bath is not recommended.
Extended storage at temperatures above 50ºC is not recommended to prevent from the formation of insoluble solids and viscosity increase.
Under recommended storage conditions, the shelf life is one year since the date of production.
Changzhou JLON Composite Co., Ltd.
A company who believes a satisfied customer is the best business accomplishment.
Changzhou JLON Composite Co. provides a wide range of reinforcements tailored to many applications such as construction, marine, pultruded profiles, transportation, wind energy, sports, etc. We’re one stop source for FRP raw materials.
In recent years we’ve entered new business axial fan and PVB/SGP film. Now there’re mainly two business sectors in our company:
A. Composite reinforcement materials and building materials:
1. Fiberglass products such as roving, chopped strand mat, woven roving, stitch mat, multiaxials, infusion mat, nonwovens for roofing, flooring, ceiling and walls of buildings
2. High performance fiber such as carbon fiber, aramid fiber, basalt fiber, high silica fiberglass, quartz
3. Core materials such as PVC/PET foam, PP honeycomb
4. Chemicals such as UP resin, vinyl ester resin, epoxy resin, SMC/BMC, MDI
5. Auxiliary materials such as infusion consumables, FRP tools
B. Axial fan:
We provide PAG and aluminum axial fan for HVAC, engineering equipment...We have different blades, hubs to satisfy customers’ specific needs.
A: Yes, We usually discuss with customers and help them find solutions.
A: Usually a sample will be prepared within one week after specification agreed.
A: Usually around 2-3 weeks after order confirmed. Exact delivery time depends on order quantity and Off-season/ busy season.
A: Offer TDS of each lot of production for confirmation before delivery.Once you have any quality problem, you can provide samples /pictures and test data. We will give you feedback in short time. If the quality problem confirmed, we will discuss about compensation with you.
A: Usually we do EXW, FOB, CIF and DDU
