As consumers become increasingly health-conscious, manufacturers of food contact materials face growing scrutiny about safety, durability, and compliance. Materials used in kitchenware, bakeware, and reusable utensils must not only perform under extreme temperatures—they must also meet global food safety standards.
Among the top materials that meet these criteria stands heat vulcanized silicone rubber. In this article, we dive into what makes heat vulcanized silicone a superior material for food grade applications, how it is used, and the role Hefeng Silicone plays in delivering safe, reliable solutions to global brands.
Heat vulcanized silicone is solid silicone cured under high heat for superior safety and durability.
It is odorless, tasteless, BPA-free, and safe for food contact.
Offers excellent thermal resistance, making it ideal for bakeware and kitchen utensils.
Globally compliant with FDA, LFGB, BFR, and other food contact standards.
Customizable in color, hardness, and shape—perfect for modern kitchen solutions.
Heat vulcanized silicone—also called high consistency rubber (HCR) or HTV silicone—is a type of solid silicone material that undergoes vulcanization using heat and pressure in the presence of a curing agent (usually peroxide or platinum-based). This results in a material with enhanced elasticity, mechanical strength, and long-term thermal stability.
Unlike liquid silicone rubber (LSR), which is injection-molded, heat vulcanized silicone is typically processed through compression molding or extrusion.
High durability under heat
Tear-resistant and flexible
Tasteless, odorless, and non-toxic
Chemically inert—does not react with food or liquids
Naturally antimicrobial and easy to clean
Thanks to these properties, heat vulcanized silicone has become an industry standard in reusable kitchen tools, baking accessories, and other food-contact components.
Heat vulcanized silicone can endure -60°C to +250°C, making it ideal for:
Baking molds
Microwave cooking
Oven use
Dishwasher cleaning
Unlike many plastics or rubbers, it does not deform, melt, or emit harmful fumes at high temperatures.
This silicone is manufactured using food-safe raw materials and complies with global regulations such as:
FDA 21 CFR 177.2600 (USA)
LFGB / BFR (Germany / EU)
REACH & RoHS (Europe)
GB 4806.11 (China Silicone Rubber Products for Food Contact)
It's completely BPA-free, phthalate-free, lead-free, and latex-free, offering peace of mind for both brands and consumers.
Heat vulcanized silicone is resistant to oil and staining. It can be easily cleaned and reused for years without degrading or releasing any substances, reducing environmental waste compared to disposable plastics.
Unlike PVC, rubber, or recycled plastics, heat vulcanized silicone won't retain food odors or affect flavor, making it perfect for everyday kitchen use.
At Hefeng Silicone, the material can be formulated in various colors, durometers (hardness), sizes, and textures, all while meeting food contact compliance.
Stringent regulations apply when any material is in contact with consumables. At Hefeng Silicone, all food-grade heat vulcanized silicone materials are rigorously tested and certified, including:
FDA CFR Title 21 Part 177.2600 — Covers rubber articles for repeated food contact.
LFGB (Lebensmittel- und Futtermittelgesetzbuch) — German standard widely recognized in Europe.
BFR Recommendations (Germany)
REACH / RoHS — For substance compliance and environmental safety.
GB 4806.11-2016 — China's food-grade silicone material standard.
Our production facilities also support ISO-quality-controlled processes to ensure reproducibility in every batch.
Here's how heat vulcanized silicone is used across modern food-grade consumer goods:
Cake molds
Muffin trays
Donut rings
Chocolate molds
These products benefit from superior thermal stability, non-stick properties, and vibrant custom colors.
Spatulas, spoons, tongs, turners
Whisks with silicone grips
Brush heads for oil and pastry
Vulcanized silicone won't melt or shed particles like plastic or nylon tools.
Heat vulcanized silicone stays flexible even when frozen and resists cracking/curling.
Reusable baking mats
Jar lids/gaskets
Food steaming baskets
Sealing rings (for mixers, rice cookers, tumblers)
These applications combine safety with high mechanical and chemical resistance.
Food manufacturers may consider TPE, PP, or PVC, but vulcanized silicone consistently outperforms them in:
| Property | Heat Vulcanized Silicone | Thermoplastics (PP, TPE, PVC) |
|---|---|---|
| Heat Resistance | Up to 250°C | Typically <120°C |
| Dishwasher Safe | Yes | Sometimes |
| Odor/Flavor Transfer | None | Can retain or absorb |
| Food Safety Compliance | Fully compliant | May need additives |
| Reusability & Lifespan | 3–10 years | 6–12 months |
| Non-toxic Under Heat | Yes | Not always |
This makes heat vulcanized silicone the smart, long-term material for reusable, food-safe tools.
Heat vulcanized silicone rubber offers the perfect combination of safety, durability, and performance for food-grade products. Whether used in professional bakeries or home kitchens, it delivers unmatched value by resisting heat, aging, contamination, and deterioration.
