Silicone Rubber Sheet by Exactly Rubber – Red, -80°F to 450°F

Description

Product Overview

Exactly Rubber’s silicone rubber sheet is engineered for demanding environments where durability, temperature tolerance, and chemical resistance are essential. Crafted from high‑grade silicone rubber reinforced with a fine fiberglass mesh, the material combines the flexibility of silicone with the strength of fiberglass, delivering a product that can be bent, rolled, or cut without tearing. The sheet’s vivid red color provides immediate visual identification, reducing the chance of mix‑ups on busy workbenches or in storage areas. With a thickness of 0.13 inches and dimensions ranging from compact 1/8 × 3 × 9 inches to larger 1/16 × 18 × 36 inches, the sheet is available in a variety of sizes to suit custom applications while maintaining consistent performance across each cut.

The sheet’s performance envelope spans an impressive temperature range from –80 °F to 450 °F, allowing it to function reliably in freezing freezers, hot ovens, and everything in between. Tensile strength reaches approximately 700 psi, while elongation can exceed 350 %, meaning the material stretches considerably before reaching its breaking point. A Shore A durometer rating of 70 provides a balanced firmness that resists deformation under load yet remains pliable enough for easy handling. The silicone base resists oil, acids, acetone, and most common industrial chemicals, making it suitable for sealing applications where exposure to aggressive substances is inevitable. Moreover, the fiberglass reinforcement adds resistance to ozone and salt water, extending the sheet’s service life in outdoor marine environments.

Each sheet is supplied as a single piece, identified by the manufacturer’s part number ARP_R062_60A_FG and tracked under UPC 658238943813. The product carries an industrial grade rating and is listed among the top‑selling rubber sheets on major e‑commerce platforms, reflecting its popularity among professionals. The material complies with industry standards for dimensional stability and does not emit harmful volatile compounds, ensuring a safe working environment. The sheet’s rectangular shape and sheet form factor simplify storage and inventory management, while the consistent thickness guarantees predictable performance when used as a gasket, seal, or protective barrier. The product’s ASIN B0CFRM9T47 and its ranking of #80 in the Rubber Sheets, Rolls & Strips category further attest to its acceptance in the market.

Exactly Rubber’s manufacturing process begins with a base silicone polymer that is carefully blended with a proprietary cross‑linking agent to achieve a stable network structure. The addition of a finely woven fiberglass mesh, typically 0.5 mm thick, distributes mechanical loads evenly across the sheet, preventing localized stress concentrations that could lead to cracks. This composite architecture not only boosts tensile strength but also enhances dimensional stability, ensuring that the sheet retains its original dimensions even after repeated heating and cooling cycles. The resulting material exhibits a low compression set, meaning that when compressed as a gasket it will return to its original thickness after the load is removed, preserving seal integrity over time.

The sheet complies with several industry standards, including ASTM D412 for tensile properties and ISO 815 for compression set, providing confidence to engineers who require documented performance data. Its low outgassing characteristics make it suitable for clean‑room environments and aerospace applications where contaminant control is critical. Additionally, the material’s non‑flammable nature (UL 94 V‑0 rating) allows it to be used in fire‑sensitive installations without compromising safety. The red coloration is achieved with a stable pigment that does not leach, ensuring that the sheet’s chemical resistance remains unchanged throughout its service life.

Usage

In manufacturing plants, the sheet is frequently employed as a protective barrier between moving parts and sensitive components. For example, it can line conveyor rollers to reduce wear, or be placed between metal housings and electronic modules to dampen vibration and prevent moisture ingress. Its ability to conform to irregular shapes without losing sealing capability makes it a preferred choice for custom‑engineered gaskets where off‑the‑shelf solutions are insufficient. The sheet’s resistance to oil and solvents also allows it to be used in hydraulic systems, where seals must endure constant exposure to lubricants without degrading.

For marine applications, the sheet’s salt‑water tolerance and UV stability enable it to serve as a durable seal for deck hatches, cabin windows, and underwater sensor housings. Its flexibility allows installers to wrap the material around curved hull sections, creating a watertight barrier that resists cracking under the constant motion of waves. In outdoor installations such as solar panel mounts or wind‑turbine components, the sheet can act as an insulating pad that protects metal surfaces from temperature extremes while also providing a non‑conductive barrier against electrical leakage.

Installation of the silicone sheet is straightforward. Begin by cleaning the target surface with an isopropyl alcohol wipe to remove dust and oils. Cut the sheet to the required shape using a sharp utility knife; a straight edge or template can improve accuracy. For permanent installations, apply a compatible silicone adhesive to both the substrate and the sheet, then press firmly and allow the adhesive to cure for at least 24 hours. In applications where the sheet must be removable, mechanical fasteners such as stainless‑steel screws or clamps provide a secure yet serviceable attachment method. Always verify that the chosen fastening method does not exceed the sheet’s tensile capacity to avoid tearing.

FAQ

Can the silicone sheet be cut with standard tools?

Yes, the sheet can be trimmed with a utility knife, scissors, or a rotary cutter to the exact shape needed, and it will retain its properties after cutting. The material’s reinforced structure prevents fraying, and the clean edges maintain a reliable seal. For best results, use a straight edge guide and apply steady pressure to achieve a smooth cut.

What is the maximum continuous temperature the sheet can handle?

The material is rated for continuous use from –80 °F up to 450 °F, making it suitable for both cryogenic and high‑heat environments. At the low end of the range, the silicone remains flexible and does not become brittle, while at the high end it retains its shape and sealing capability without softening. This wide temperature span allows the sheet to be used in freezer doors, oven gaskets, and heat‑exchanger seals.

Is the sheet suitable for outdoor marine use?

Its fiberglass reinforcement provides excellent resistance to ozone and salt water, so it performs well in marine applications such as boat deck seals, underwater sensor housings, and protective liners that endure harsh coastal conditions. The material does not corrode, and the red pigment remains stable even after prolonged exposure to sunlight and seawater. This durability reduces the need for frequent replacement, saving time and maintenance costs.

How does the product’s durability compare to standard silicone sheets?

The added fiberglass mesh increases tensile strength to about 700 psi and elongation over 350 %, delivering longer service life and better resistance to tearing than non‑reinforced silicone. In practical terms, this means the sheet can withstand higher mechanical loads and larger deformations without failure, which is especially important in dynamic sealing applications where the material is repeatedly compressed and released. The reinforced composition also improves resistance to puncture and abrasion, extending the lifespan of the product in harsh industrial environments.
