HONGYE SILICONE’s FDA Liquid silicone rubber is a premium dual-component Addition Curing Silicone, tailored for global B2B purchasers in food-contact, medical, and daily-use product manufacturing. As a national high-tech enterprise with standardized production and one-stop solutions, this FDA-certified silicone features strict compliance with USA CFR 21.Part.177.2600, non-toxic odorless performance, excellent heat resistance, and easy operation. It supports room/heat curing, deep curing without thickness limits, and flexible customization, helping purchasers meet global food/medical safety standards, reduce compliance risks, and enhance product competitiveness.
Product Overview
Our FDA liquid silicone Rubber is a high-performance RTV 2 Silicone Rubber, composed of high-purity flowable Part A (base rubber) and Part B (curing agent), adopting advanced addition curing technology. As a professional Food grade mold silicone, it solves the pain point of ordinary liquid silicone failing to meet FDA standards or having volatile substance residues. Unlike Condensation Curing Silicone Mold Rubber, it produces no harmful by-products, has ultra-low volatile methyl siloxane (D4-D9) residues, and fully complies with FDA and RoHS standards, making it ideal for food-contact molds, medical accessories, and safe daily-use silicone products.

Product Features & Advantages
1. Strict FDA Compliance: Fully meets USA CFR 21.Part.177.2600 and RoHS standards, ultra-low volatile substance and D4-D9 residues, non-toxic, odorless, no harmful by-products, far superior to non-FDA liquid silicone.
2. Excellent Safety & Purity: Made of high-purity Silicone raw materials, free of heavy metals and toxic additives, suitable for direct food contact and medical scenarios. 3. Versatile Curing & Operation: Supports room/heat curing, deep curing without thickness limits; 1:1 mix ratio, simple stirring for 2~3 minutes, no professional skills required, adapting to small-batch and mass production.
4. Strong Durability: High tensile/tear strength, good elasticity, mold cycle life up to 120 times, reducing replacement costs and improving production efficiency.
5. Flexible Customization: Color, hardness, operating time, and curing time can be tailored to food/medical/daily-use needs, without compromising FDA compliance.
6. Cost-Effective: Stable batch quality reduces defect rates; FDA compliance eliminates export and market access risks, saving compliance costs.
How to Use (Step-by-Step Guide)
1. Mix Part A and Part B of the FDA liquid silicone rubber in a 1:1 weight ratio, stirring thoroughly in an irregular direction for 2~3 minutes until uniform and bubble-free, ensuring safety and compliance.
2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity and vacuum strength) to eliminate bubbles and reduce volatile residues.
3. Pour the degassed silicone slowly into molds, leveraging good fluidity to fill all details and gaps.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing; post-cure if needed to enhance stability.
5. Store unused silicone in sealed food-grade packaging, indoor storage away from sunlight and rain, use within 10 months; avoid contact with N, P, S-containing compounds to prevent curing failure.
Application Scenarios
Our FDA Liquid Silicone Rubber is widely used in global food, medical, and daily-use fields, including food grade Mold Silicone (cake, candy, baking molds), silicone tableware (spatulas, plates), medical accessories, high-transparency mold silicone for food, and precision Prototype silicone for safe products. It also applies to food-contact Pad Printing Silicone, bringing tangible value: meeting global safety standards, eliminating export compliance risks, improving product qualification rate by 45%+, and helping B2B purchasers gain trust in the high-end safe silicone market.
