Industrial Strength Liquid Silicone Mold Rubber

HONGYE SILICONE’s Industrial Strength liquid silicone Mold Rubber is a high-performance dual-component Addition Curing Silicone, tailored for global B2B purchasers in heavy-duty industrial mold manufacturing, large-scale casting, and high-wear scenarios. As a national high-tech enterprise with standardized production and one-stop solutions, this industrial-grade silicone features exceptional tensile/tear strength, FDA and RoHS certification, non-toxic odorless performance, and easy operation. It supports room/heat curing, deep curing without thickness limits, and flexible customization, helping purchasers reduce mold replacement costs, improve production efficiency, and meet the rigorous demands of industrial-scale mold making.

 

 

Product Overview

Our Industrial Strength Liquid Silicone Mold Rubber is a professional-grade RTV 2 Silicone Rubber, composed of high-purity flowable Part A (base rubber) and Part B (curing agent), adopting advanced addition curing technology optimized for industrial durability. Its core advantage is industrial-grade toughness and wear resistance, solving the pain point of ordinary Mold Making Silicone with poor load-bearing capacity and short service life in heavy-duty scenarios. Unlike condensation curing silicone mold rubber with weak mechanical properties, it achieves shrink-free deep curing, produces no toxic by-products, and maintains stable performance under harsh industrial conditions, perfectly matching the needs of large-scale, high-frequency mold manufacturing.

4. Easy Industrial Operation: 1:1 mix ratio, simple stirring, compatible with industrial production equipment; supports room/heat curing, adapting to mass production and large-scale mold making.

5. Flexible Customization: Hardness, operating time, curing time, and color can be tailored to industrial needs (large components, high-wear molds) without compromising toughness.

6. Cost-Effective: Long service life and stable batch quality reduce downtime and rework costs, improving overall industrial production profitability.

 

How to Use (Step-by-Step for Industrial Mold Making)

1. Mix Part A and Part B of the industrial strength liquid silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free, ensuring full integration to maintain industrial-grade toughness.

2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity, weight, and vacuum strength) to eliminate bubbles, avoiding defects in large-scale molds.

3. Pour the degassed silicone into industrial molds slowly, leveraging good fluidity to fill all details and gaps, ensuring uniform thickness for heavy-duty use.

4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing; post-cure if needed to enhance wear resistance for high-frequency demolding.

5. Store unused silicone in sealed industrial 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 Industrial Strength Liquid Silicone Mold Rubber is widely used in global industrial mold manufacturing scenarios, including large cement components, cultural stone, concrete molds, metal crafts, alloy car accessories, epoxy/polyester resin industrial molds, and high-precision industrial handboard models. It brings tangible value: extending mold service life by 50%+, improving production efficiency by 35%, reducing replacement and rework costs, and helping B2B purchasers meet the rigorous demands of industrial-scale production, enhancing competitiveness in the global industrial mold market.
