Product Description

HONG YE JIE’s liquid silicone for silicone sheet molds is a high-performance two-component Addition Curing Silicone, engineered for flat silicone sheet mold making. It supports room/heat curing with easy operation, featuring FDA food-grade safety, -60°C to 250°C temperature resistance, and excellent fluidity for uniform sheet thickness. Integrating Mold Making Silicone, liquid silicone, RTV 2 Silicone Rubber and Industrial mold silicone rubber advantages, it offers shrinkage-free deep curing and high durability. Certified by ISO9001/CE/UL, it meets industrial production standards for global buyers.

Product Overview

This specialized silicone consists of flowable A/B components, tailored for manufacturing flat silicone sheet molds that demand consistent thickness and smooth surface. With 20+ years of silicone manufacturing expertise, our product cures into a tough elastic body without deformation, unaffected by mold thickness. Its superior fluidity ensures even pouring and full coverage, suitable for both small-batch customization and large-scale industrial production of silicone sheets, providing one-stop mold solutions for industrial and craft sectors.

Technical Specifications

Base Material: Addition-cure organic silicone rubber; Mix Ratio (A:B): 1:1 by weight; Operating Time (25°C): 30-40 minutes (customizable); Curing Time (25°C): 4-5 hours, 80-120°C: 30-60 minutes; Temperature Resistance: -60°C to 250°C; Tear Strength: ≥22 kN/m; Hardness: 20-40 Shore A (customizable); Shelf Life: 10 months (sealed, indoor storage, no sun/rain exposure).

Product Features & Advantages

1. Uniform Thickness Guarantee: Shrinkage-free curing and excellent fluidity ensure consistent silicone sheet thickness, avoiding unevenness.

2. Safe & Versatile: FDA-certified, non-toxic odorless, suitable for food-contact and industrial silicone sheets.

3. Easy Industrial Operation: Dual curing methods fit production lines, simple mixing reduces operational complexity.

4. Durable & Cost-Saving: High tensile/tear resistance, 500+ reuse times, lowering mold replacement costs.

5. Stable Quality: Standardized production with pre-production sampling and pre-shipment inspection, backed by ISO9001.

How to Use

1. Clean and dry the flat mold frame, ensure no dust or oil to guarantee surface smoothness.

2. Mix A/B at 1:1 weight ratio, stir thoroughly for 2-3 minutes until uniform in color.

3. Vacuum defoam for 2-5 minutes (adjust by viscosity/weight) to eliminate bubbles.

4. Pour the mixture evenly into the mold frame, spread to desired thickness.

5. Cure at room temperature (4-5 hours) or 80-120°C (30-60 minutes) until fully solidified.

6. Demold gently and trim edges for finished silicone sheet molds.

Production Process

1. Select high-purity industrial-grade raw materials, conduct strict impurity and performance testing. 2. Precision formula mixing with temperature-controlled reaction to ensure stable fluidity. 3. Separate A/B component filling and sealed packaging to prevent contamination. 4. Test hardness, tear strength and fluidity of finished products. 5. Vacuum sealing with product specifications and operation guidelines.

FAQ

1. Can it make large-size silicone sheet molds?

Yes, it supports large-area pouring with uniform thickness.

2. How to ensure mold flatness?

Use a leveled mold frame and even pouring vacuum defoaming.

3. Is it compatible with epoxy resin sheets?

Yes, it has anti-adhesion for easy demolding.

4. Can curing time be shortened for mass production?

Yes, formula adjustment or temperature increase accelerates curing.

5. What if silicone is stored beyond shelf life?

It may lose fluidity and curing performance; use within 10 months.
