Product Description

HONG YE JIE’s liquid silicone for off-road tire molds is a high-performance addition-curing RTV-2 silicone rubber, designed for precision mold making of off-road tire prototypes and industrial parts. Featuring excellent fluidity, high tear resistance, and wide temperature tolerance (-60℃~250℃), it cures at room temperature or with heat. FDA-certified, non-toxic, and customizable, this Industrial mold silicone rubber ensures multiple mold turns, reduces production costs, and meets ISO, CE, UL standards, trusted by global B2B buyers.

Product Overview

Our liquid silicone for off-road tire molds is a professional two-component addition-curing silicone material, consisting of flowable Part A and Part B. Tailored for replicating complex off-road tire textures (such as deep treads and anti-slip patterns), this Mold Making Silicone combines easy operation with superior durability. Beyond off-road tire molds, it’s widely used in high-grade alloy auto accessories, epoxy resin products, precision hand prototypes, and rapid prototyping, providing a one-stop industrial mold solution for manufacturers.

Technical Specifications

- Type: Addition-curing RTV-2 Silicone Rubber

- Mix Ratio: 1:1 (by weight)

- Operating Time (25℃): 30-40 minutes (customizable)

- Curing Time (25℃): 4-5 hours; 80-120℃ for tens of minutes (customizable)

- Temperature Resistance: -60℃ to 250℃

- Certifications: ISO9001, CE, UL, FDA

- Shelf Life: 10 months (sealed, indoor storage)

- Core Material: High-purity silicone oil + platinum catalyst

Product Features & Advantages

1. Deep & Uniform Curing: Unrestricted by mold thickness, ensuring consistent hardness for large off-road tire molds.

2. Superior Durability: High tensile and tear resistance, supporting 20-50 mold turns, reducing replacement frequency.

3. Excellent Fluidity: Easily fills fine tread details, capturing precise textures for lifelike tire replicas.

4. Flexible Operation: Room temperature or heat-curable, adapting to different production lines.

5. Safe & Compliant: FDA-certified, non-toxic, odorless, meeting industrial and environmental standards.

6. Customizable: Tailor color, viscosity, operating/curing time to match specific mold requirements.

How to Use

1. Prepare the master model (off-road tire prototype) and clean it thoroughly to remove dust.

2. Mix Part A and Part B in 1:1 weight ratio, stirring evenly for 2-3 minutes to avoid lumps.

3. Perform vacuum degassing for 2-5 minutes (adjust based on viscosity and vacuum strength) to eliminate air bubbles.

4. Pour the mixed silicone into the mold frame, ensuring full coverage of the master model’s treads.

5. Cure at 25℃ for 4-5 hours or heat to 80-120℃ for faster curing (tens of minutes).

6. Demold gently and trim excess silicone; the mold is ready for off-road tire production.

Application Scenarios

- Off-road tire prototype molds (ATV, UTV, 4x4 vehicle tires)

- Alloy auto accessory molds (off-road wheel hubs, decorative parts)

- Epoxy/polyester resin tire model production

- Large industrial part molds (heavy-duty off-road equipment components)

- Precision hand prototyping for automotive R&D

- Rapid tooling for small-batch off-road tire manufacturing

Production Process

1. Raw Material Selection: Adopt high-quality Silicone raw materials and platinum catalysts for stable performance.

2. Precision Blending: Automated mixing with strict ratio control to ensure consistency.

3. Quality Testing: Test viscosity, curing speed, and tear strength before production.

4. Vacuum Degassing: Remove air bubbles to guarantee mold precision.

5. Automated Filling: Seal in airtight containers to maintain freshness.

6. Final Inspection: 100% inspection before shipment, complying with ISO9001 standards.

FAQ

1. Can it be used for large off-road tire molds (over 1m in diameter)?

Yes, its deep curing feature supports large-size molds without hardness inconsistency.

2. How to extend the mold’s service life?

Store the mold in a cool, dry place after use; avoid sharp tools during demolding.

3. Is the silicone compatible with epoxy resin for tire casting?

Absolutely, it’s compatible with epoxy, polyester resin, and concrete for various casting materials.

4. What’s the minimum order quantity (MOQ)?

MOQ is 50kg, with bulk order discounts available.

5. Can you adjust the silicone’s hardness for soft tire molds?

Yes, we offer hardness customization (Shore 10-80A) to match different mold requirements.
