MDI Applications
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.

Storage
Since 44V20L 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 44V20L should be kept properly closed and stored indoors at ambient temperature (15-35ºC) in a well-ventilated area. Storage at low temperature (below5ºC) 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.
Shelf Life
Under recommended storage conditions, the shelf life of 44V20L is one year since the date of production.

1. What is Polyurethane System material?
Polyurethane system is a compound that includes 2 components, which are component A and Component B, Component A is blended polyol, Component B is Isocyanate. TDI or MDI is belong to Isocyanate.
2. Are you a factory or trading company?
We are a cooperated polyurethane system material factory, we provide bicomponents PU material (Component A & Component B) to factories or manufacturers who make molded foam products.
3. What is your MOQ?
Our minimum ordered quantity for single component is 10KG, our smallest drum can carry 10KG.
4. How to ship samples and mixed chemicals in bulk to clients?
For small quantity, we ship by air or land, since the chemicals are liquid which belongs to sensitive cargo, the air shipping fee will be higher than common goods.
5. Is your sample free?
Our sample is not free, but we can return the sample fee to you once your ordered quantity reaches 20 Tons.
6. What types of PU foam system material you can offer?
We offer flexible system, semi-rigid foam system, rigid foam system, integral skin foam system, polyurethane elastomer system.
7. What applications can use your PU system?
For flexible foam system: bedding, mattresses, pillow, furniture, automotive interiors, shoes insoles, bra cup, GEl, toys, packaging.
For rigid foam system: insulation, insulated windows, doors, roofs, air barrier, cooling box, skateboards, PU imitation woods, PU ceiling borders.
8. Do you provide product design and developing service?
We can develop foam formulation according to your technical requirements after business relations established.
9. Is your chemical formulation open to clients?
Our formulation is unique, and non-disclosure, we can offer the technical parameters to you, and teach you how to mix the materials with the proportion.
