Product Description

HONGYE SILICONE, a national high-tech enterprise, provides high-quality Addition Curing Silicone for casting applications. Our Mold Making Silicone is a two-component liquid silicone (A&B), which can cure at room temperature or by heating with easy operation. It meets FDA food grade standards, features excellent high and low temperature resistance (-60℃~250℃), high tensile strength and tear resistance. Widely used in various mold manufacturing and rapid prototyping, we offer customized solutions and one-stop service.

Product Overview

As a professional manufacturer of mold making silicone, HONGYE SILICONE focuses on providing high-performance Platinum cured mold silicone for global B2B buyers. Our Liquid Mold Silicone is a two-component addition curing silicone material, composed of two flowable liquid components (A and B). It supports both room-temperature and heat curing, with simple operation, making it suitable for various high-precision casting scenarios. We adhere to standardized production, provide one-stop overall solutions, and can customize the product according to customers’ specific requirements, such as color, operation time and curing time.

Technical Specifications

Component Ratio: A:B = 1:1 (by weight); Operation Time: 30~40 minutes at room temperature (25℃); Curing Time: 4~5 hours at room temperature, 10~30 minutes at 80~120℃ (customizable); Temperature Resistance: -60℃ ~ 250℃; Certification: FDA food grade; Shelf Life: 10 months (sealed, indoor storage, away from sun and rain); Type: Addition curing silicone, RTV 2 Silicone Rubber.

Product Features & Advantages

Our Industrial mold silicone rubber has outstanding performance and unique advantages compared with competitors: 1. Deep curing without being limited by product thickness, ensuring uniform curing effect. 2. Food grade, non-toxic and odorless, passing FDA certification, safe for food contact mold making. 3. Excellent high and low temperature resistance, adapting to various harsh working environments. 4. Good fluidity, easy to pour, simple operation, suitable for mass production. 5. High tensile strength and tear resistance, high mold turnover times and long service life, reducing procurement costs. 6. Fully customizable, including color, operation time, curing time, to meet diverse needs.

How to Use

Step 1: Component Mixing - Mix component A and B in a 1:1 weight ratio evenly for 2-3 minutes. Step 2: Vacuum Defoaming - Put the mixed silicone into a vacuum machine for 2-5 minutes (adjust according to viscosity, weight and vacuum strength). Step 3: Casting & Curing - Pour the defoamed silicone into the mold, cure at room temperature for 4-5 hours or heat at 80~120℃ for tens of minutes. Step 4: Storage - Seal the unused silicone and store it indoors, avoiding sun and rain, with a shelf life of 10 months.

Application Scenarios

Our mold making silicone is widely used in multiple industries: high-grade and high-simulation food product molds, metal crafts and alloy car accessory molds, epoxy resin and polyester resin casting molds, large cement components and cultural stone molds, high-precision prototype and rapid prototyping design. It is also applicable to Toy mold silicone and Shoe mold silicone production, bringing stable performance and high efficiency to your production.

Product Value for Buyers

Choosing our platinum cured Mold Silicone can help you reduce production costs (long service life and high turnover times), improve production efficiency (easy operation and fast curing), and enhance product quality (high precision and stable performance).
