Foams silicone for thermal insulation

Description of Foams silicone for thermal insulation

HY-F662 is a RTV-2 liquid silicone rubber, general called two-component room temperature vulcanization silicone, part A is silicone rubber, part B is catalyst / curing agent. Foam silicone is platinum cure silicone / addition cure silicone, a kind of environmentally friendly material which is totally non-toxic ,tasteless, safety and health, food grade.

Application of Foams silicone for thermal insulation

HY-F662 Foaming Liquid Silicone Rubber,which is widely used as a filling material for Mannequin,Streetlight Filling,seat cushion, silicone clone human, polyurethane furniture, sheet material and other rubber products.since silicone rubber foam is very lightweight, very soft and has good cushioning effect.



 

Technical Parameters of Foams silicone for thermal insulation

Note: Above technical datasheet doesn't include all of our products, and it's not the fixed data, they can be adjustable according to customer's requirement.

ADVANTAGES of RTV Foams silicone for thermal insulation
- FDA certified, medical grade, totally nontoxic, odorless, harmless, and eco-friendly
- Wide hardness from 0-10 shore C.
- Wide bubbling times
- High temperature resistance
- Good flexibility, permeability and insulativity
- No oily problem

NOTICE of Foams silicone for thermal insulation
1. In order to avoid no curing problem, it cannot mix with condensation cure silicone rubber, organic matter which is containing N, S, P organics and ionic compound like Sn, As,Hg, Ph. What's more, please do not smoke when operating the foaming silicone rubber, otherwise, it will cause to no curing problem too.
2, The solidification of platinum cure silicone rubber is particularly affected by temperature, higher the temperature is, faster the curing time will be.

PROCESSING RECOMMENDATIONS

PREPARATION...

Store and use at room temperature (73°F/23°C). These products have a limited shelf life and should be used as soon as possible. Good room size ventilation is essential. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.

Cure Inhibition - Addition cured silicones may be inhibited by certain contaminants such as sulfur, polyesters,certain wood surfaces, epoxies, urethane rubber and tin catalyzed silicones resulting in tackiness at the pattern interface or a total lack of cure throughout the mold. If compatibility between the rubber and the surface is a concern, a small-scale test is recommended. Apply a small amount of foam onto a non-critical area of the pattern.Inhibition has occurred if the matrerial is gummy or uncured after the recommended cure time has passed. This product will not cure against tin-based silicone rubbers.

Applying A Release Agent - Silicone Foams will stick to some surfaces and a release agent may be necessary to facilitate demolding. When casting Silicone Foams into or over other platinum silicones, apply Ease Release *200 prior to applying foam.

IMPORTANT: To ensure thorough coverage, lightly brush the release agent with a soft

brush over all surfaces. Let the release agent dry for 15 minutes.Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

MEASURING & MIXING...

Mixing - Mixing can be done by hand or using a drill and a mixer attachment, such as a "squirrel" mixer. After dispensing required amounts of Parts A and B into mixing container, mix thoroughly for 30 seconds. Stir quickly and deliberately, making sure you scrape the sides and bottom of the mixing container several times. Be careful not to splash material out of the container. Remember, foam cures quickly. Do not delay between mixing and pouring. Elevated temperatures will result in a reduced pot life and cure time.

POURING, CURING & PERFORMANCE...

Warning - A small amount of Hydrogen gas is released as part of the A:B reaction. Use only with adequate ventilation and do not breathe fumes. Also do not smoke or have other ignition sources in proximity to this product during mixing and pouring.

Pouring - For best results, pour your mixture in a single spot at the lowest point of the containment field and let the mixture seek its own level.

Handling Strength is 20 minutes with full cure in 1 hour at room temperature. Foam color will darken over time. Adding silicone pigments will help stabilize color of cured foam. To adhere Silicone Foams to other platinum silicones, best adhesion is realized when poured against newly cured platinum silicone rubber.

Results May Vary: This material is subject to variables such as high or low environmental temperatures. A small test to determine how material performs for your application is recommended.

Improve Surface Finish and Minimize Voids With Back Pressure

Use a board that will completely cover the mold opening. Using a "¾ (2 cm) drill bit, drill 3 holes in the board spaced a few inches / cm apart. Make sure that, when the board is placed over the mold opening, the holes are over the mold cavity and rising foam will be able to make it through. Apply Ease Release *200 thoroughly too both sides of the board and into the drilled holes. Mix and pour foam into mold cavity and place board over mold opening. Hold board firmly in place. As foam rises in the mold cavity, some foam will grow out of the drilled holes. After the foam stops growing, you can let go of the board. Do not demold for at least 20 minutes.

Demold - After 20 minutes, cut excess material that came through holes. Gently remove board and casting.
