Product Description

HONGYE SILICONE, a national high-tech enterprise, specializes in durable liquid silicone for mold production. Our Mold Making Silicone is a two-component Addition Curing Silicone, composed of flowable A&B components, supporting room-temperature and heat curing with easy operation. It boasts FDA-certified food grade safety, excellent high-low temperature resistance (-60℃~250℃), high durability, and multiple mold turnover times. We provide standardized production, one-stop solutions, and customized services for global B2B buyers.

Product Overview

HONGYE SILICONE’s durable liquid silicone is a professional-grade mold making silicone designed for high-efficiency, long-lasting mold production. As a one-stop solution provider with standardized production, we offer addition curing silicone that is a two-component (A&B) flowable liquid. It features easy operation, flexible curing methods (room temperature or heating), and can be customized in color, operation time and curing time to meet diverse industrial needs. Our RTV 2 Silicone Rubber is trusted by global buyers for its durability and stable performance.

Technical Specifications

Type: Addition curing silicone, RTV 2 Silicone Rubber; Component Ratio: A:B = 1:1 (by weight); Operation Time: 30~40 minutes (25℃, room temperature); Curing Time: 4~5 hours (room temperature), 10~30 minutes (80~120℃, customizable); Temperature Resistance: -60℃ ~ 250℃; Certification: FDA food grade; Shelf Life: 10 months (sealed, indoor storage, away from sun and rain); Core Performance: High tensile strength, tear resistance, deep curing without thickness limitation.

Product Features & Advantages

Our Industrial mold silicone rubber stands out with unique durability and performance advantages: 1. Deep curing design, not limited by product thickness, ensuring uniform and stable curing. 2. Food grade, non-toxic and odorless, passing FDA certification, safe for food contact molds. 3. Excellent temperature resistance, adapting to harsh working environments. 4. Good fluidity, easy to pour, simple operation, improving production efficiency. 5. High tensile and tear resistance, more mold turnover times and longer service life, reducing procurement costs. 6. Fully customizable to match your specific production requirements.

How to Use

Step 1: Mix A and B components in 1:1 weight ratio evenly for 2-3 minutes. Step 2: Conduct vacuum defoaming for 2-5 minutes (adjust according to silicone viscosity, weight and vacuum strength). Step 3: Pour the defoamed silicone into molds, cure at room temperature for 4-5 hours or heat at 80~120℃ for tens of minutes. Step 4: Store unused silicone in sealed condition indoors, avoiding sun and rain, with 10-month shelf life.

Application Scenarios

Our durable Liquid Mold Silicone is widely applied in various industries: high-grade simulated food molds, metal crafts and alloy car accessory molds, epoxy/polyester resin casting molds, large cement components and cultural stone molds, high-precision prototype and rapid prototyping (compatible with Prototype silicone and Rapid prototyping silicone). It is also suitable for Toy mold silicone and Shoe mold silicone production, delivering reliable performance.
