HONG YE SILICONE Flexible RTV Silicone Rubber for Moldmaking is a premium two-component RTV 2 Silicone Rubber, designed for small-size (≤10cm) crafts and fine-pattern mold making. As professional Mold Making Silicone and liquid silicone , it features exceptional fluidity, room-temperature curing (25℃, 5-7hrs), good tensile/tear strength and low shrinkage. With ultra-flexible texture and easy demolding, it suits resin products, decorations, sculptures, soap and candle arts. The Platinum cured mold silicone version meets food grade standards, supporting safe contact applications, while reducing mold replacement costs and improving production efficiency for global B2B buyers.
Product Overview
This specialized Industrial mold silicone rubber is engineered for small-scale, high-precision mold making, focusing on flexible texture to replicate intricate details without damaging castings. It is a two-part flowable liquid product (Part A: base silicone, Part B: curing agent), requiring no special equipment for room-temperature vulcanization. Its optimized fluidity ensures full filling of fine mold cavities, making it ideal for products with delicate patterns. Widely adopted by craft manufacturers, it balances usability and durability, with stable performance across repeated duplication cycles.

Product Features & Advantages
Ultra-flexible texture (10-25 Shore A) ensures easy demolding of delicate small crafts, avoiding pattern damage. Exceptional fluidity enables full coverage of intricate cavities, capturing ultra-fine details accurately. Room-temperature curing (25℃) saves energy and simplifies production without heating equipment. Good tensile and tear strength extends mold service life, supporting multiple duplication cycles. Low shrinkage guarantees consistent dimensional stability of cast products across batches. Dual curing systems offer cost-effective (condensation) and food-safe (platinum, Food grade mold silicone) options. Simple operability reduces training costs for production teams.
How to Use the Product
Step 1: Prepare the small-size prototype (≤10cm) and molding frame, fix the prototype firmly; apply release agent for glass/ceramic prototypes to prevent sticking.
Step 2: Select condensation or platinum curing silicone, weigh Part A and Part B according to the recommended ratio, stir evenly.
Step 3: Perform vacuum defoaming for 1-2 minutes to eliminate air bubbles (critical for fine patterns).
Step 4: Pour the mixed silicone into the frame, ensuring full filling of all detail areas.
Step 5: Cure at 25℃ for 5-7 hours (full curing), demold gently after 2-3 hours if urgent, then use the mold for casting.
Application Scenarios
Widely used for mold making of small-size (≤10cm) resin products, decorations, arts and crafts, sculptures, soap arts, candle arts and fine-pattern toys. Suitable for craft workshops, small-batch toy manufacturers, soap/candle factories and handmade gift enterprises. It helps buyers improve product detail accuracy (reducing defective rates by 30%+), shorten production cycles via easy operability, and lower mold replacement costs through durable performance, enhancing market competitiveness in fine-craft segments.
Certifications and Compliance
The product complies with ISO 9001 quality management system and CE industrial standards. Platinum cured Mold Silicone meets FDA and EU food grade mold silicone regulations, safe for soap, candle and other indirect food-contact applications. All formulas conform to international chemical transportation and import requirements, supporting smooth cross-border B2B bulk procurement.
Customization Options
Support customization of hardness (10-25 Shore A), viscosity (optimized for extra-fine patterns), curing speed (3-8hrs adjustable) and color. Provide formula modification for slightly larger molds (10-15cm) or ultra-delicate pattern molding. Customize packaging specifications (small sample jars for testing, large drums for mass production) and mixing ratios to match production lines.
Production Process
Adopt high-purity Silicone raw materials, go through precise proportioning, closed vacuum mixing (to maintain fluidity and avoid bubbles), multi-index testing (hardness, flexibility, shrinkage rate), automatic filling and sealed packaging. Each batch undergoes strict quality inspection, with mature production lines ensuring consistent performance. Sufficient inventory guarantees on-time delivery for small-batch and bulk orders.
FAQ
Q1: What’s the maximum mold size it can make?
A1: Optimized for ≤10cm small-size crafts; customizable for 10-15cm molds with formula adjustment.
Q2: Can it be used for food-contact molds (e.g., candy)?
A2: Yes, the platinum cured version is food grade mold silicone, compliant with FDA standards.
Q3: How to speed up curing?
A3: Increase ambient temperature to 30-35℃ (shortens curing time to 3-4hrs); avoid excessive curing agent addition.
Q4: Do I need a release agent for resin prototypes?
A4: No, porous materials like resin do not require it; only for smooth non-porous surfaces (glass/ceramic).
Q5: How many times can one mold be reused?
A5: With good tear strength, it can be reused 50-100 times depending on use and maintenance.
