HONG YE SILICONE Candle Making Silicone Rubber is a professional two-component RTV 2 Silicone Rubber, tailored for candle crafting with moderately soft hardness (neither too hard nor too soft) to perfectly replicate fine patterns. As premium Mold Making Silicone and liquid silicone , it features low viscosity, room-temperature curing (25℃, 2-6hrs), good tensile/tear strength and low shrinkage. Suitable for small-size mold pouring, it also applies to plaster moulding, soap making, toys and sculptures. The Platinum cured mold silicone version meets food grade standards, ensuring safety for skin-contact products, while helping global B2B buyers reduce defective rates and improve production efficiency.
Product Overview
This specialized Industrial mold silicone rubber is engineered for candle making, with optimized hardness to balance detail replication and easy demolding—avoiding candle damage or pattern loss. 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 low viscosity enables smooth pouring into intricate mold cavities, making it ideal for decorative candles with fine details. The product’s versatility extends to multiple craft scenarios, serving as a cost-effective and stable molding solution for candle factories, craft workshops and gift manufacturers.

Product Features & Advantages
Moderately soft hardness (15-30 Shore A) perfectly replicates candle details while ensuring easy demolding, no candle breakage or pattern distortion. Low viscosity enables smooth pouring, fully filling complex and small mold cavities. Room-temperature curing (25℃) saves energy and simplifies production, no heating equipment required. Good tensile and tear strength extends mold service life, supporting multiple duplication cycles and reducing replacement costs. Low shrinkage guarantees consistent candle size and shape across batches. Dual curing systems offer cost-effective (condensation) and food-safe (platinum, Food grade mold silicone) options. Versatile for multi-craft scenarios, reducing buyers’ need for multiple molding materials.
How to Use the Product
Step 1: Prepare the candle prototype and small-size molding frame, fix the prototype firmly; apply release agent only 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 for 2-3 minutes.
Step 3: Perform vacuum defoaming for 1-2 minutes to eliminate air bubbles (critical for smooth candle surfaces).
Step 4: Pour the mixed silicone into the frame, ensuring full coverage of all fine patterns.
Step 5: Cure at 25℃ for 2-6 hours (full curing), demold gently and use the mold for candle pouring.
Application Scenarios
Widely used for making molds for decorative candles, scented candles, shaped candles and other candle arts. It is also suitable for plaster moulding, lost wax casting, toy and artwork molding, soap making and small sculpture replication. Ideal for candle factories, handmade craft workshops, gift customization enterprises and plaster product manufacturers. The product helps buyers improve candle appearance quality (fine pattern replication), reduce defective rates by 25%+, shorten production cycles via easy operation, and lower comprehensive costs through multi-scenario applicability.
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 skin-contact crafts. All formulas conform to international chemical transportation and import requirements, supporting smooth cross-border B2B bulk procurement and market access.
Customization Options
Support customization of hardness (15-30 Shore A) to adapt to different candle pattern complexities, viscosity adjustment for faster/smoother pouring, and curing speed optimization (1-8hrs) to match production efficiency. Provide color customization and formula modification for large-size candle molds. Customize packaging specifications (small sample jars for testing, large drums for mass production) according to buyer needs.
Production Process
Adopt high-purity Silicone raw materials, go through precise proportioning, closed vacuum mixing (to maintain low viscosity and avoid bubbles), multi-index testing (hardness, tensile strength, shrinkage rate), automatic filling and sealed packaging. Each batch undergoes strict quality inspection to ensure consistent performance. Mature production lines and sufficient inventory guarantee on-time delivery for both small-batch and bulk orders.
FAQ
Q1: What is the optimal hardness for candle molds?
A1: 15-25 Shore A is best—it balances fine detail replication and easy demolding without damaging candles.
Q2: Is this silicone safe for soap making?
A2: Yes, the platinum cured version is food grade mold silicone, compliant with safety standards for skin-contact products.
Q3: Can I speed up the curing time?
A3: Increase ambient temperature to 30-35℃ (shortens curing to 1-3hrs); do not exceed recommended curing agent dosage.
Q4: Do I need a release agent for candle molds?
A4: No, the non-stick surface enables easy demolding; release agent is only needed for glass/ceramic prototypes.
Q5: How many times can one mold be reused?
A5: With good tear strength, it can be reused 50-100 times under normal use and proper maintenance.
