Does silicone melt or burn?

Silicone baking sheet how to use it

Need high-temperature silicone that can withstand extreme temperatures? Don’t worry! This guide will explain how to properly use a heat-resistant sealant, and which products hold up best to the hottest jobs.

High-temperature silicone is a very stable adhesive that forms a long-lasting seal that won’t shrink or crack. The chemical composition of this silicone gives it a very high thermal resistance, slowing heat transmission. This makes it an ideal material for resisting high temperatures.

Most high-temperature silicone sealants are heat resistant to some extent. However, they do not all withstand the same temperature intensity. High-temperature silicone is made specifically to withstand extreme temperatures, so it is important to consult the technical information on the silicone packaging before making your choice.

High-temperature silicones work very well in areas and joints exposed to intense heat or cold. The most common high-temperature sealants typically withstand temperatures between -50 °C and 300 °C, although some heat-resistant industrial silicones can withstand higher temperatures. However, this higher heat resistance comes at a price: the sealant is stiffer and does not withstand mechanical loads well.

Silicone glue gun

The various kitchen utensils are relatively new on the market, and have come on strong in a wide range of functions: from spatulas to trays and oven mats, from steamers for microwave steaming, and even baking pans, to freezer ice cube making dies.

Recently the OCU made a study of the efficiency of different silicone steamers, where it offered a series of tips before using them for the first time, consisting of preparing a paste with water, flour and oil, coating the silicone containers with them, baking the paste and then discarding it. The intention is that it absorbs possible compounds from migration from the plastic surface.

Silicone utensils can therefore be used perfectly well for both freezing and baking, provided that the maximum temperature is not exceeded. Silicone also has the advantage of being flexible, so that it can be easily stored even when folded. Another advantage is that food does not stick to the surface and cleaning is extremely easy, with just a little soap and without having to scrape. Especially in the case of baking pans, there is no need to sprinkle the baking pans with flour.

Silicone is water-removable

Silicone is mainly composed of oxygen and silicon.  Although many of us do not know it, silicon is one of the most common elements found in nature; in fact, almost 30% of the earth’s surface is composed of this material.

One of the great advantages of silicon is that it is elastic and resistant to high temperatures. For all these reasons and, above all, for its sealing capacity, silicon is widely used in the industrial field as an adhesive or lubricant, and also in other fields, for example in the medical sector.  Silicone is also used in a large number of everyday consumer products, especially hair care products and skin creams.

Silicone has a high degree of elasticity and flexibility, which makes it highly resistant to traction. It is also a powerful insulator (both thermal and electrical) and manages to maintain its properties unchanged even in environments with extreme temperatures.

What can be glued with the silicone gun

For domestic use few kinds of rods are available and sometimes they are interchangeable. For industrial use many kinds of rods are available for special purposes, the most common diameters being 12 mm (0.47 inches), 15 mm (0.59 inches) and 45 mm (1.8 inches). The rods have different open times (the working time to bond), varying from a second or two to several minutes.

Glue guns come in low and high temperature versions and are used depending on the type of glue sticks to be used. Low-temperature sticks heat up to 120 °C (248 °F), and are suitable for crafts with fabric, wood and plastics, for example, while high-temperature sticks require temperatures around 195 °C (383 °F) and result in stronger adhesion. The dual guns have a switch that allows both types of rods to be used.
