Why Does My Paraffin Wax Crack?
Key Causes
✅ Rapid Cooling: Wax shrinkage exceeds 6% when cooled >2°C/min
✅ Low-Grade Wax: Impurities (<0.5% oil content) weaken structural bonds
✅ Wrong Additives: Overuse of stearic acid (>15%) causes brittleness
Junda's Solutions
🔧 Use Our High Melt Point Wax
60-66°C melting range reduces thermal stress
98.6% purity minimizes micro-cracks
Add 3-5% microcrystalline wax (Ask for free samples!)
⚠️ Pro Tip: Preheat molds to 45-50°C – our tests show 80% crack reduction
2. How to Prevent Mold Growth in Wax Products?
Root Causes
✅ Humidity Absorption: Unrefined wax holds 0.1%+ moisture
✅ Organic Contamination: Natural oils attract fungi
✅ Storage Issues: Temperatures 25-35°C accelerate spoilage
Fushun's Anti-Mold Technology
🔧 Hydrotreated Paraffin Wax (HPW Series)
<0.02% moisture content via vacuum dehydration
Food-grade oxidation stabilizers inhibit microbial growth
UV-resistant packaging for tropical climates
📦 Storage Guide: Keep below 22°C with our silica gel container inserts (Free with bulk orders)
3. Why Won’t My Wax Release from Molds?
Failure Analysis
✅ Surface Roughness: Ra >3.2μm causes mechanical locking
✅ Wax-Mold CTE Mismatch: ΔCTE >2×10⁻⁵/°C creates vacuum adhesion
✅ Inadequate Release Agents: Silicone sprays leave residue
