For resin craft molds: Prioritize addition-cure silicone (low shrinkage <0.1%), Shore A 15-25 (flexible for details), resin compatibility, tear strength ≥20 kN/m, and 20-40 mins pot life.

For plaster mold castings: Pick addition-cure silicone with Shore A 25-35 (balances flexibility and rigidity), water resistance (plaster is wet), and low shrinkage to preserve fine textures.

For candle molds: Opt for food-grade addition-cure silicone (non-toxic), Shore A 20-30 (easy demolding of wax), and heat resistance (to handle warm wax pouring).

For metal casting rubber molds: Choose high-temperature resistant silicone (up to 200℃+), Shore A 40-50 (rigid for shape retention), and high tensile strength (≥5 MPa) to withstand metal pressure.

For soap molds: Use food-grade addition-cure silicone (non-toxic, chemical-resistant), Shore A 15-25 (flexible for easy soap release), and smooth finish for clean soap surfaces.

For food-grade molds: Ensure FDA/LFGB certification, addition-cure type (no harmful byproducts), Shore A 20-30 (flexible), and non-reactive with acids/alkalis in food.

For epoxy resin jewelry molds: Select addition-cure silicone (Shore A 10-20, ultra-flexible for tiny details), low shrinkage, and resin compatibility to avoid clouding or adhesion.

For high-temperature casting molds: Prioritize silicone with heat resistance ≥180℃, Shore A 35-45 (structural stability), and low thermal expansion to retain shape under heat.

For large-scale sculpture molds: Choose addition-cure silicone with high tear strength (≥35 kN/m), Shore A 25-35 (balances flexibility and support), and long pot life (60+ mins) for easy pouring over large surfaces.
