Diestone High-Strength Powder (500g/1KG)

• Composition: High-purity calcium sulfate hemihydrate (modified alpha-hemihydrate).
• Water/Powder Ratio: Typically a low ratio, around 20-23 mL of water per 100 g of powder, which contributes to its high density and strength.
• Compressive Strength (Dry): Can reach up to 10,000–18,000 psi (pounds per square inch).
• Setting Expansion: Generally very low, around 0.08% to 0.10%.

• Type IV die stone uses a lower W/P ratio (around 23-30 mL of water to 100g of powder).
• Type V die stone has an even higher strength and expansion, requiring a similar or slightly different specific ratio depending on the manufacturer.
Additives are sometimes used to adjust properties like setting time or expansion:
• Accelerators (e.g., potassium sulfate) can limit setting expansion.
• Retarders (e.g., borax) can slow the setting process.
• Hardeners (e.g., colloidal silica) can improve abrasion resistance.
• Keep it Dry: Store powder in a cool, dry place, away from humidity, and keep containers tightly sealed to prevent moisture absorption.
• Cleanliness: Use dedicated, clean tools and containers, and always use distilled or deionized water to avoid impurities.
• Dust Control: Be aware that the dust can irritate respiratory systems; work in fresh air and consider dust extraction.

• Detailed Product Descriptions: Provide comprehensive details on your e-commerce platform, including:
Type: e.g., Type IV or Type V gypsum.
• Specifications: Compressive strength (e.g., 10,000 psi), mixing ratio (water to powder), setting time, and expansion percentage.
• Recommended Uses: Clearly state if it is for fixed prostheses, crown & bridge models, or general study models.
• Compatibility: Mention compatibility with various impression materials
