The Benefits Using Expanded Microspheres in Model Making Board
Using expanded microspheres in model making board offers several benefits:
1. Weight Reduction of Model Making Board:
Even a small addition of Waytop DET can significantly reduce the weight of the board while forming a closed cell structure, leading to a more uniform foam compared to traditional materials.
2. Insulation of Model Making Board:
Expanded microspheres improve sound and vibration damping, as well as thermal insulation in the model making board.
3. Production Advantages:
The elasticity and internal pressure of microspheres can reduce shrinkage during production and prevent stress cracking in the final product.
4. Post-Treatment Benefits:
Dust from microspheres is less irritating to the respiratory system compared to other materials containing glass microspheres. It is also less abrasive, reducing wear on machine parts.
5. Surface Finish:
The small particle size of Waytop microspheres results in a finer surface finish on the model making board, eliminating the need for crack fillers and allowing for immediate lacquering.
How to use expanded microspheres in model making board
To use expanded microspheres in model making board effectively, follow these recommendations:
1. Choice of Waytop Grade:
For model making materials, it is recommended to use Waytop WP40D or WP80D. Consider using WP80D if there are concerns about mechanical forces during processing,.
2. Mixing:
Add Waytop DET into the polyol component of a two-component polyurethane system. It can also be added just before injection into the mold alongside the polyol and iso-cyanate. Ensure that the microspheres can withstand the mixing process without damage.
3. Handling:
Waytop has developed handling systems to prevent dusting issues when working with expanded microspheres. Refer to the “Handling of dry expanded Waytop microspheres” guide for more information.
By incorporating expanded microspheres like Waytop DET into your model making board and following the recommended practices, you can enjoy the benefits of lightweight, insulated, and high-quality finished products.
