Addition Curing Silicone, specialized in high-safety polymer molding for diverse scenarios. As a national high-tech enterprise with standardized production and one-stop solutions, this safe-grade liquid is FDA, RoHS and EN71 certified, non-toxic, odorless, and free of harmful residues (including volatile methyl siloxane D4-D9), featuring reliable safety performance, easy operation, and stable quality. It caters to global B2B purchasers pursuing high-safety molding materials, supporting food-contact, craft, and precision scenarios, flexible customization, and mass production, helping avoid safety risks and meet international safety standards.
Product Overview
Our Safe Grade Polymer Rubber Molding Liquid is a high-performance
RTV 2 Silicone Rubber, a polymer polysiloxane material composed of high-purity flowable Part A (base rubber) and Part B (curing agent), adopting advanced addition curing technology. Focused on core safety, it supports both room-temperature and heat curing with simple operation, achieving shrink-free deep curing without thickness limits, producing no toxic by-products, and strictly controlling harmful residues to solve the safety risks of ordinary
Mold Making Silicone (such as volatile substance residues). Unlike
Condensation Curing Silicone Mold Rubber with potential safety hazards, it is the trusted choice for global B2B purchasers in food-contact, toy, and high-standard molding fields.

Product Features & Advantages
1. Superior Safety Performance: FDA, RoHS and EN71 certified, non-toxic, odorless, no harmful by-products, and free of volatile methyl siloxane (D4-D9) residues, avoiding risks to human health and the environment, far safer than ordinary
Mold Silicone and condensation curing silicone mold rubber.
2. Strict Quality Control: Standardized production and multi-layer safety testing (raw material, mixing, curing) ensure consistent safety performance, complying with global food-contact and toy safety standards.
3. Versatile Safety Adaptability: Suitable for food-contact, toy, and precision molding scenarios, with stable chemical properties that do not react with acids, alkalis, or salts (except caustic alkali and hydrofluoric acid).
4. Excellent Molding Performance: Good fluidity for easy pouring and precise detail replication, high tensile/tear strength, supporting 90~110 mold cycles, balancing safety and durability.
5. Easy Operation & Customization: 1:1 mix ratio, simple stirring; hardness, operating time, and curing time can be customized without compromising safety performance.
6. Reliable Safety Guarantee: As a national high-tech enterprise, we provide one-stop safety solutions, ensuring each batch meets international safety standards for B2B purchasers.
How to Use (Step-by-Step for Safe Molding)
1. Mix Part A and Part B of the safe grade polymer rubber molding liquid in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free, ensuring safe and even integration.
2. Perform vacuum degassing for 2~5 minutes; adjust time based on viscosity to eliminate bubbles and avoid molding defects.
3. Pour the degassed liquid into mold masters, leveraging good fluidity to fill all details and gaps, ensuring safe and precise molding.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing, maintaining safety performance after curing.
5. Store unused liquid in sealed packaging, indoor storage away from sunlight and rain, use within 10 months; proper storage ensures no safety performance degradation or residue generation.
Application Scenarios
Our Safe Grade Polymer Rubber Molding Liquid is widely used in global high-safety molding fields, including food-contact molds (high-simulation food, tableware), toy molds, metal crafts, alloy car accessories, epoxy resin molds, precision handboard models, and children’s product molds. It brings tangible value: meeting international safety standards, avoiding safety-related penalties and product recalls, improving product competitiveness, reducing safety risk costs by 35%+, and supporting mass production, helping B2B purchasers gain trust in global high-safety markets.
