Platinum Silicone Rubber 15A for Candle Molds

HY-E615 is a food-grade addition curing platinum silicone rubber with 15 Shore A hardness, designed for high-precision candle mold making and food contact applications. Its near-zero shrinkage, high tear strength, and FDA compliance make it a reliable choice for professional mold makers seeking consistent reproduction quality.
1. Product Overview
HY-E615 is a two-component (A+B) platinum-cured liquid silicone rubber from the HY-E series. With 15 Shore A hardness, it offers a soft yet durable feel, ideal for applications requiring detailed impression and flexible demolding. As a food-grade material, it meets stringent safety standards for direct food contact, making it suitable for chocolate, candy, and cake decoration molds.
2. Technical Specifications
Model: HY-E615. Hardness: 15 Shore A. Mix ratio: 1:1 (A:B). Color: Translucent. Viscosity: moderate flow, easy to pour. Curing time: room temperature 8-12 hours for full cure; accelerated at 60-80°C within 1-2 hours. Temperature resistance range: -10°C to 350°C after full cure. Shrinkage rate: less than 0.1% (near-zero). Tensile strength: ≥6.0 MPa. Tear strength: ≥25 kN/m. Packaging options: 1kg/5kg/20kg/25kg/200kg per container.

4. Product Features
The platinum-cured addition system delivers near-zero shrinkage, ensuring precise dimensional accuracy for every mold reproduction. High tear strength extends mold lifespan even under repeated use cycles. The material flows easily into complex mold patterns, capturing fine details with high fidelity. Unlike condensation-cure silicones, HY-E615 produces no alcohol byproducts during curing and maintains dimensional stability over time. Food-grade certification makes it safe for direct contact with food items such as chocolate, candy, and cake decorations.
5. How to Use
Stir parts A and B separately before use. Mix A and B at a 1:1 ratio by weight, stirring thoroughly for 2-3 minutes. Degas the mixture under vacuum for 5-10 minutes to remove trapped air bubbles. Pour the mixture into the master mold gently from a single point. Allow curing at room temperature for 8-12 hours, or accelerate with heat at 60-80°C for 1-2 hours. Demold after full cure, and the silicone mold is ready for production.
6. Application Scenarios
Candle mold making — reproduces intricate candle designs with sharp detail. Chocolate and candy molds — food-grade safety for edible product molding. Soap and cosmetic mold production — flexible demolding without damaging delicate shapes. Resin jewelry and craft molds — captures fine textures and embedded elements. Cake decoration and fondant molds — food contact safe for baking applications.
7. Buyer Benefits
Reduce material waste through near-zero shrinkage and predictable cure behavior. Extend mold service life with high tear strength material, reducing replacement frequency. Achieve faster production cycles with optional heat acceleration. Minimize surface defects from bubble inclusions with vacuum-degas compatibility. Access flexible packaging options matched to your production volume.
8. Certifications and Compliance
HY-E615 carries FDA (TS26030035), RoHS (TS21121372), REACH (TS21121373), and ISO9001:2008 (CN11/31147) certifications. UL listed (E354635-213401069). Complies with European and North American food contact safety regulations. Chemical inertness ensures no leaching or contamination during use.
9. Customization Options
Hardness can be adjusted within the 10-50 Shore A range by selecting alternate HY-E series grades. Color customization available — translucent, white, or colored per customer specification. Packaging options include 1kg samples, 5kg/20kg/25kg standard drums, and bulk 200kg packaging. Custom mix ratio and viscosity adjustments available for specialized applications. MOQ starts from 2kg for trial orders.
10. Production Process and Quality Control
Pre-production sample molding is offered to validate material selection before mass production. The factory operates 20 production lines with a monthly output of 220 tons. Each batch undergoes full inspection before shipment, covering hardness, tensile strength, and dimensional compliance. The facility is ISO9001 certified with traceable batch records.
11. FAQ
Q: Can HY-E615 be used for food-grade chocolate molds? A: Yes. HY-E615 is FDA certified for food contact, making it suitable for chocolate, candy, and cake decoration molds.

Q: What is the shelf life of this silicone rubber? A: When stored in a cool, dry place away from direct sunlight, the shelf life is 12 months from the production date.

Q: How many molds can one batch produce? A: Under proper usage conditions, the material can achieve hundreds of reproduction cycles depending on the complexity of the mold and the material being cast.

Q: Do you provide free samples? A: Sample requests are welcome. Contact HONG YE SILICONE directly for sample availability and shipping terms.

Q: Can I mix different hardness grades? A: It is not recommended to mix different hardness grades as it may affect curing characteristics and final physical properties.
