Product Features & Advantages

1. Exceptional Longevity: Enhanced wear-resistant formula and high tensile/tear strength support 120~150 mold cycles, 30% longer than ordinary Mold Silicone and far superior to condensation curing silicone mold rubber, reducing replacement frequency.

2. Strong Wear & Aging Resistance: Stable chemical properties, resistance to wear, oxidation, and high/low temperatures (-60℃~250℃), maintaining performance after long-term use without hardening or cracking.

3. Food-Grade Safety: FDA and RoHS certified, non-toxic, odorless, no harmful by-products, suitable for food-contact mold fabrication and high-standard scenarios.

4. Easy Operation & Customization: 1:1 mix ratio, simple stirring; hardness, operating time, and curing time can be customized without compromising durability.

5. Cost-Effective: Extended service life reduces mold replacement costs by 40%+, lowering overall production costs for purchasers.

6. Stable Batch Quality: Standardized production ensures consistent durability across batches, avoiding quality fluctuations that affect service life.

 

How to Use (Step-by-Step for Long-Lasting Mold Fabrication)

1. Mix Part A and Part B of the long lasting rubber in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free, ensuring even integration to maximize durability.

2. Perform vacuum degassing for 2~5 minutes; adjust time based on viscosity to eliminate bubbles, which can reduce mold strength and service life.

3. Pour the degassed rubber into mold masters, leveraging good fluidity to fill all details and gaps, ensuring uniform thickness for long-term use.

4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing, ensuring full curing to enhance durability.

5. Store unused rubber in sealed packaging, indoor storage away from sunlight and rain, use within 10 months; proper storage preserves its wear-resistant performance and longevity.

 

Application Scenarios

Our Long Lasting Rubber For Mold Fabrication is widely used in global long-term mold fabrication, including industrial concrete/cultural stone molds, metal crafts, alloy car accessories, epoxy resin/polyester resin molds, large cement components, and precision handboard models. It brings tangible value: extending mold service life by 30%+, reducing replacement costs by 40%+, improving production efficiency by reducing downtime, and supporting mass production, helping B2B purchasers enhance cost-effectiveness and market competitiveness.
