Two component Polyurethane Pre-polymer for the shoe mould
Description
This system materials is Bi-component. A is polyol component, and B is MDI-terminated pre-polymers.
Application
This system material is used to produce various Pu mould, such as shoe mould, concrete mould tec. It can substitute silicone rubber to produce “artificial culture stone”.
Characteristic
It has excellent processing properties, cured under room temperature, short demould time, and the color can be changed by adding pigment. The final products are transparent which enjoy good abrasion resistance, water resistance, good resilience. The hardness is in the 40 to 90 shore A hardness range.

Operation by manual
1．Take certain A component to make reserve.
2. Calculate B component to make reserve.
3. Pour B component to A component and stir evenly.
4. Cast the mixture of step 3 to the mould.
6. Open the mould when the product is hard.
7. Post cure 16 hours at 100℃.
Note: The mixture in the step 3 can be vacuumized to get rid of bubble.
Operation by casting machine
1. Put some A component into A tank, vacuumize to make reserve.
2. Put some B component into B tank, vacuumize to make reserve.
3. Cast the two materials according the ratio to the mould.
4. Open the mould when the product is hard.
5. Post cure 16 hours at 100℃.
Safety
Use in a well ventilated area. Avoid contact with skin using protective gloves and protective clothing. Repeated or prolonged contact on the skin may cause an allergic reaction.
Eye protection is extremely important. Always use approved safety glasses or goggles when handling this product.

Note 1
It generally cures to a demouldable state in 30 to 60 minutes; however, thin sections or certain part configurations may require more in-mould cure time. Sections that are less than 3mm may require more before demould. It depends on different products.
Note 2
Both components should be mixed before each use to ensure uniformity of the materials. Opened containers of material should be prevented moisture contamination from humid air.
