RTV-2 Liquid Silicone Rubber for Candle Mold Making - High Tear Strength Food Grade

Product Description

Product Description

 

Our RTV-2 Liquid Silicone Rubber is a two component room temperature vulcanizing silicone specifically formulated for manufacturing durable high precision molds for all types of candles including pillar candles votive candles container candles taper candles floating candles wax melts tealights and 3D novelty shaped candles.

The material is designed to withstand repeated exposure to hot wax typically 60 to 80 degrees Celsius without degradation swelling or deformation. Its excellent flexibility high tear strength and non stick surface ensure that finished wax candles release cleanly and easily from the mold even from complex shapes with undercuts and fine details.

Whether your customers are professional candle manufacturers producing thousands of candles per week or DIY crafters making candles at home for personal use or small business our silicone delivers the performance durability and safety required for high quality candle molds that can be used hundreds of times.

 

Key Features

*Food Grade Safety - Compliant with FDA for food contact applications. Safe for direct contact with candle wax and fragrances. Non toxic odorless and BPA free.

*High Tear Strength - Tear strength of 20 to 25 kN m ensures molds withstand repeated flexing and stretching during demolding. Ideal for complex candle shapes with undercuts thin sections and intricate surface details.

*Low Shrinkage - Linear shrinkage of 0.1 to 0.3 percent ensures dimensional accuracy. Maintains consistent candle dimensions across hundreds of casting cycles.

*Excellent Detail Replication - Low viscosity formulation flows smoothly into every cavity and fine detail. Captures intricate patterns textures logos and surface finishes with exceptional fidelity.

*Easy Demolding - Silicone s inherent non stick surface allows cured wax candles to release cleanly. No heavy mold release agents required saving production time and cost.

*Heat Resistance - Operating temperature up to 200 degrees Celsius well above typical wax pouring temperatures of 60 to 80 degrees Celsius. No swelling softening or deformation during wax casting cycles.

*Room Temperature Curing - Vulcanizes at room temperature within 3 to 6 hours. No heating equipment required. Heat acceleration available for high volume production.

*Adjustable Hardness - Shore A hardness from 00A to 50A customizable. Soft grades for complex undercut molds. Medium grades for standard pillar and votive molds. Hard

ADDITIONAL INFORMATION
Reproduction of Vertical Surfaces
If a skin mold is required of a vertical object or surface and cannot be made by normal pouring techniques, the catalyzed mixture can be made non flowable by the addition of thixotropic agent.

1. Prepare the original as described earlier.
2. Brush the original with a thin layer of catalyzed mixture. Repeat the operation when the first layer has started to cure, to achieve a coating thickness of >2mm. Leave to cure at
room temperature until the material is tacky.
3. Prepare a new catalyzed mixture of silicone and add 1% by weight of thixotropic additive and mix thoroughly until a paste consistency is reached. De-airing of the mixture is not
required.
4. Using a spatula, cover the coated original with the thixotropic coating until all undercuts are filled; leave to cure for 24 hours at room temperature.
5. Construct a support mold using polyester resin or plaster and allow to set in contact with the silicone coating. Carefully remove the support mold. Peel the rubber off the original
and place in the support mold.

Use at High Temperatures
Some molds produced from condensation cure silicone rubbers can degrade when exposed to temperatures above 150°C (302°F) over a period of time or when totally confined in
storage at high ambient temperatures. This can result in softening and loss of elastic properties.
Resistance to Casting Materials
The chemical resistance of fully cured silicone rubber is excellent, and similar to all condensation cure silicone elastomers. It should be noted however that ultimately, resins and
other aggressive casting materials will attack silicone molds, changing physical properties, surface release and possibly mold dimensions. Molds should be checked periodically during
long production runs.
