1. Micro-computer controlling high pressure pu foam machine and self-cleaning type low pressure pu foam machine can only be used for material ratio (POLY:ISO) 1:1, rigid foam product production

2. Wood-imitation product, density begins from 300kg/m3, and the mould would be metal moulds

3. The pressure of spray machine is for spraying pressure, not air pressure. And the spray machine would be devided into low pressure pu foam machine and high pressure pu foam spray machine.

4. High pressure pu foam spray machine has bigger working area, and the hose can be from 15 meter to 90 meters. Standard equpment would be 15 meter with 2 meter gun connecting hose.

5. Elastomer machine has two types: a. high temperature elastomer machine, b. low temperature elastomer machine. If you are using MOCA, as one of the material, you would need high pressure elastomer machine.

6. To produce flexible foam product, you can use PLC high pressure pu foam machine, low pressure flexible pu foam machine and also cyclopentane high pressure pu foam machine. Cyclopentane foam machine would be good for envirionment protecting demanded area.

7. PLC high pressure pu foam machine would be good for both rigid and flexible foam product. And big output work would be good.

8. The reaction temperature of polyurethane material would be from 20 to 25 degree. Chiller can be used if you are at high temperature area, and also if you want to produce very high end product, you may also build a green-house, to keep the temperature the same.

9. Generally, rigid foam product mould takes more pressure than flexible foam product.

10. About material ratio, generally, more Isocyanate the product would has more rigidity.
