FDA Compliant Low Viscosity Food Grade Liquid Silicone Rubber 15 Shore A 1:1 China Factory for Chocolate Candy Molds

FDA Compliant Low Viscosity Food Grade Liquid Silicone Rubber 15 Shore A 1:1 for Chocolate Candy Molds

This FDA compliant, low viscosity food grade platinum cure (addition-cure) 1:1 liquid silicone rubber is a two-component mold-making silicone supplied as HN-E615 in the HN-E6XX series by a direct China manufacturer, Shenzhen Hanast New Materials Co., Ltd. Its low viscosity gives excellent flow for fine chocolate and candy mold detail, and the simple 1:1 mix ratio cures at room temperature or by gentle heating — delivering a soft, tough, translucent elastomer with no low-molecule release and ultra-low shrinkage, ideal for food-contact RTV-2 molds.

Key Features

• FDA compliant food grade — suitable for direct food contact; MSDS, RoHS and REACH certified for export markets
• Low viscosity (3500±500 mPa·s) — excellent flow for intricate chocolate and candy mold detail
• Shore A 15±2 hardness (HN-E615) — soft grade for delicate food molds and easy demolding
• Two-component addition-cure (platinum) RTV-2 system; foolproof 1:1 mix ratio by weight
• Ultra-low linear shrinkage (≤0.1%) for excellent dimensional accuracy on complex geometries
• High elongation (600%) for flexible demolding; high tensile strength (5.7 MPa), tear strength 17 kN/m
• Room-temperature cure (3-4 h at 25°C); heat-accelerated to ≤20 min at 80-100°C; 30-40 min pot life
• Non-toxic, odourless, non-corrosive; no low-molecule release; −50°C to 200°C; 12-month shelf life

Typical Applications

• Chocolate, praline, candy and confectionery molds (food-safe)
• Gummy, jelly, fondant, marzipan and pastry molds
• Cake, cupcake and baking molds; baking mats and liners; ice cube and dessert molds
• Butter, cheese and sugar-art molds; confectionery and bakery production
• Handmade soap molds, wax and aromatic candle molds
• High-precision jewellery, figurine and arts & crafts molds; resin casting
• Plaster, gypsum and cultural stone craft molds
• Medical and skin-safe products; soft prosthetics and simulation models
• Rapid prototyping and precision model reproduction
• Any food-contact RTV-2 mold requiring low viscosity, high detail and easy demolding

Technical Data (HN-E615, 15 Shore A)

Mixing & Application

1. Pre-mix: stir Components A and B thoroughly before use to ensure homogeneity.
2. Weigh A and B at exactly 1:1 by weight using a precision scale.
3. Mix thoroughly for 2-3 minutes, scraping the container walls and bottom.
4. Degas under vacuum to remove entrapped air for bubble-free molds.
5. Pour into the clean, dry mold frame within the 30-40 min pot life.
6. Cure at room temperature for 3-4 h, or heat at 80-100°C for ≤20 min; demold after full cure.

FAQ

1. Q: What is the mix ratio and cure time of this low viscosity silicone rubber?

A: Mix Component A and Component B at a 1:1 ratio by weight. Pot life is 30-40 minutes at 25°C. It cures in 3-4 hours at room temperature, or in 20 minutes or less at 80-100°C for fast production.

2. Q: Is this low viscosity silicone rubber FDA compliant and food safe?

A: Yes. The HN-E615 is a food-grade platinum-cure (addition) silicone that is FDA compliant and certified with MSDS, RoHS and REACH. It is non-toxic, odourless and releases no low-molecule by-products during cure, making it suitable for chocolate, candy and baking molds.

3. Q: Why choose a 15 Shore A low viscosity grade?

A: The 15 Shore A (HN-E615) soft grade with low viscosity (3500±500 mPa·s) flows into fine detail and demolds easily, ideal for chocolate, candy, gummy and delicate food molds. Harder grades (20-40 Shore A) are available for more rigid mold requirements.

4. Q: What must I avoid to prevent platinum catalyst poisoning?

A: Platinum-cure silicone may fail to cure in contact with organotin compounds, sulfur / polysulfide, amines, polyurethane, phosphorus compounds, organic acids and solder flux. Keep all substrates, tools and containers clean, and never mix with tin-cure silicone residues.

5. Q: What are the MOQ, supply ability and delivery time?

A: MOQ starts at 20 kg. Supply ability is 50 tons per month, with about 3-5 days lead time for samples and 10-15 days for bulk orders. Components A and B are packed in 10/20/25 kg iron or plastic drums, or as 20/40/50 kg kit sets.
