HONGYE SILICONE’s High Tear Strength Liquid silicone rubber is a premium dual-component Addition Curing Silicone, tailored for global B2B purchasers in industrial mold making, high-wear scenarios, and precision casting industries. As a national high-tech enterprise with standardized production and one-stop solutions, this silicone features exceptional tear resistance, high tensile strength, wide temperature resistance, and easy operation. It supports room/heat curing, deep curing without thickness limits, and flexible customization, helping purchasers reduce mold damage, increase mold cycles, lower production costs, and meet strict industrial durability requirements.
Product Overview
Our High Tear Strength liquid silicone Rubber is a high-performance Industrial mold silicone rubber, composed of high-purity flowable Part A (base rubber) and Part B (curing agent), adopting advanced addition curing technology. It solves the pain point of ordinary liquid silicone or Condensation Curing Silicone Mold Rubber with low tear strength, easy cracking, and short service life. Unlike standard Mold Making Silicone, it is specially formulated to enhance tear resistance, maintaining structural integrity even under frequent demolding and high stress, making it ideal for high-wear molds, precision casting, and industrial components requiring strong durability.

Product Features & Advantages
1. Exceptional Tear Resistance: Tear strength ≥38N/mm, 30% higher than ordinary liquid silicone, resistant to cracking, tearing, and damage during demolding and use, ensuring long-term mold integrity.
2. High Tensile & Durability: High tensile strength (≥5.2MPa), good elasticity, mold cycle life up to 200 times, reducing mold replacement frequency and costs.
3. Advanced Addition Curing: No harmful by-products, deep curing without thickness limits, low shrinkage rate, ensuring precise mold replication and stable performance.
4. Versatile Operation: 1:1 mix ratio, simple stirring for 2~3 minutes, compatible with industrial equipment; supports room/heat curing, adapting to small-batch and mass production.
5. Wide Adaptability: (-60℃~250℃), resistant to aging and chemicals, suitable for harsh industrial environments and high-wear scenarios.
6. Flexible Customization: Hardness, tear strength, curing time, and color can be tailored to industrial needs, without compromising durability.
How to Use (Step-by-Step Guide)
1. Mix Part A and Part B of the high tear strength liquid silicone rubber in a 1:1 weight ratio, stirring thoroughly with industrial equipment in an irregular direction for 2~3 minutes until uniform and bubble-free.
2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity and vacuum strength) to eliminate bubbles, preventing mold defects and weakening tear resistance.
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 to enhance tear strength further.
5. Store unused silicone in sealed 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 High Tear Strength Liquid Silicone Rubber is widely used in global industrial fields, including high-wear mold making silicone, precision casting molds, epoxy/polyester resin casting, large cement components, metal crafts, and Rapid prototyping silicone. It also applies to Shoe mold silicone, Toy mold silicone, and industrial high-wear components, bringing tangible value: increasing mold cycle life by 60%+, reducing replacement costs by 40%+, and helping B2B purchasers gain advantages in the high-durability silicone market.
