Tips
Q: How many kgs of silicone I need to make a mold, like 1m*1m?
A: First, you change the "m" to "cm". Then the V(volume)=100cm(length)*100cm(width)*1.5cm(height or thickness) =15000cm3
→ the density of the liquid silicone is 1.1g/cm3→ the quantity= 15000cm3* 1.1g/cm3=16500g(16.5kg)
Q: How can I know the thickness of the silicone mold?
A: For the pouring way, if you do not have a plaster have a base to keep its shape (like square), then we usually suggest that 2-3cm is enough. If yes, then 1-1.5 cm is enough.
Q: Why is there not enough 25kgs silicone in the drum?
A: V=m/p. because the different of the silicone viscosity, so there will be a little difference. When the viscosity is lower, there will be 26kgs or more. In contrast, there will be 24kgs or little.
Q: Why should I choose RUIHE Silicone?
A: We can offer you the sample, sample test, technical support, engineers' instruction, new products development, new market expansion, factory visiting reception, latest silicone news in China, related products purchasing assistance, 15-year experience in producing silicone rubber.
Q: Which shipping method can we choose?
A: You can choose your usual logistics company and logistics method.
