1. Q: Is this silicone rubber safe for direct food contact?
A: Yes. It is an FDA compliant food grade liquid silicone rubber suitable for chocolate, candy, baking and other food-contact molds. It is odorless, non-toxic and non-corrosive, and supplied with FDA, MSDS, RoHS and REACH documentation for export markets.
2. Q: What does "low viscosity" mean for chocolate and candy molds?
A: The low viscosity (4000 ± 500 mPa·s; 800-20000 cps customizable) gives excellent flow, so the silicone fills intricate chocolate, candy and pastry details without trapped air for accurate, high-definition molds.
3. Q: What is the mixing ratio and cure schedule?
A: Mix Component A and Component B at 1:1 by weight. Pot life is 30-40 minutes at 25°C. Cure in 3-4 hours at room temperature, or accelerate to about 20 minutes at 80-100°C. Vacuum-degas the mixed silicone for bubble-free molds.
4. Q: What hardness and viscosity options are available?
A: The HN-E6XX series covers 0-60 Shore A with a shared 1:1 ratio and 30-40 minute pot life. This listing is HN-E620 (20 Shore A). Typical food-contact grades are 10-40 Shore A; hardness, viscosity and colour are customizable, and softer grades suit delicate chocolate molds while harder grades suit larger baking molds.
5. Q: What are the MOQ, sample policy and delivery time?
A: MOQ is only 1 kg, with free trial samples available. Supply ability is 100 tons per month. Packaging is 20 kg / 25 kg / 200 kg drums with MSDS and TDS included; shelf life 12 months. Lead time is about 3-5 days for samples and 10-15 days for bulk/OEM orders — contact us for factory-direct bulk pricing.
