Silicone Mats & Pads

When rigid heaters can't fit, flex or deliver even heat, silicone heater mats and pads solve the problem. Designed and built in-house, each mat is a thin, waterproof silicone-rubber heater engineered for precise temperature control on complex surfaces — from batteries and gas cylinders to concrete drying and process equipment.

Operating from –60 °C to +250 °C, each heater is built to match your application: your dimensions, your power, your control strategy. Standard products are available for common applications, but most solutions are engineered to order — built around the object you need to heat.

What are silicone heater mats and pads?

A silicone heater mat — sometimes called a silicone heating pad, silicone rubber heater or flexible silicone heater — is a thin heating element laminated between two layers of fibreglass-reinforced silicone rubber. Because silicone stays flexible across a wide temperature range and resists water, oils and most chemicals, the heater can be wrapped around curved surfaces, adhered to tank walls, or laid flat against a cold plate without cracking or losing contact. Compared to mica or cartridge heaters, silicone heaters run at lower watt densities, heat more evenly, and tolerate repeated bending and thermal cycling.

Why silicone heaters are the right choice

  • Flexible: conforms to drums, IBCs, gas cylinders, battery packs, curved deck boards and irregular shapes
  • Fast, even heat: the thin profile puts the element close to the object — almost no thermal lag
  • Wide operating range: typically –60 °C to +250 °C depending on model
  • Waterproof: silicone envelope handles washdown, humid and outdoor environments
  • Durable: withstands repeated flexing, vibration and thermal cycling
  • Customisable: any size, power rating, voltage, lead configuration, bi-metal thermostat or digital controller

Standard and custom-built

The products listed above cover the most common jobs we're asked to solve:

  • Silicone heating mats and pads for general process and surface heating
  • Gas cylinder heating pads for 22 kg and 33 kg LPG bottles — improving vaporisation and flow in cold conditions
  • Silicone battery heaters that keep lithium and lead-acid packs inside their safe operating window in EVs, off-grid installations and outdoor equipment
  • Flood Repair Heating Mats that accelerate the structural drying of concrete, screed and masonry after water damage — often paired with dehumidifiers
  • FlexDeck Board Bending Heater — a heating blanket engineered to form curved deck boards and composite panels

If none of these match your application, tell us what you're heating and how hot it needs to get — we build silicone heaters to order, in small series, from a single unit upward. Custom mats can be specified with bi-metal safety thermostats, overheating cut-outs, PT100 sensors, or paired with one of our digital temperature controllers for precise closed-loop control.

Custom silicone heaters — built to your specification

Most silicone heater mats we deliver are custom-built. That's because real-world applications rarely match standard sizes or power ratings. We design each heater based on:

  • Surface geometry and material
  • Target temperature and heat-up time
  • Available voltage and power limits
  • Environmental conditions (indoor, outdoor, washdown)
  • Required control strategy and safety level

From one-off prototypes to small production runs, we build silicone heaters that fit the job — not the other way around.

Technical specifications at a glance

  • Operating temperature: –60 °C to +250 °C (standard ranges: –60 to +250 °C, 0 to +150 °C, and 70 °C fixed)
  • Power ratings: 400 W, 500 W and up to 1,932 W per unit — custom watt densities on request
  • Voltage: 230 V single-phase stocked; 12 V, 24 V, 48 V and three-phase available on request
  • Temperature control: bi-metal thermostat, digital controller, or adjustable overheating protection
  • Ingress protection: silicone rubber envelope withstands washdown and outdoor conditions
  • Construction: fibreglass-reinforced silicone rubber, etched-foil or resistance-wire element, PTFE-insulated leads

Typical applications

  • LPG and gas cylinder heating at filling stations, forklift depots and process plants
  • Battery pack pre-heating in EVs, energy storage systems and cold-weather machinery
  • Concrete, screed and masonry drying after water damage or new construction
  • Deck board bending, composite forming and marine fit-out
  • Drum and IBC viscosity management for resins, syrups, waxes and oils
  • Sub-zero equipment warming in telecom cabinets and outdoor enclosures
  • Laboratory and pilot-plant process heating on non-standard geometries

Are silicone heating mats safe?

Properly specified silicone heater mats are one of the safest flexible heating technologies available. The silicone envelope is self-extinguishing, the heating element is fully sealed, and every mat we build is fitted with overheat protection — either a bi-metal safety thermostat or a dedicated overheating cut-out. The key is correct sizing: watt density, surface area and control strategy have to match the duty. That specification step is something we do for every custom order — tell us the object and the target temperature, and we'll make sure the mat stays inside its safe operating window for the lifetime of the job.

Why buy silicone heaters from HXP

We design and manufacture silicone heaters in Europe — we don't import them. The mat on your loading dock was specified by an engineer who understood your duty, built in small series or as a one-off, and tested before it left the workshop. If you need something non-standard — and most serious heating jobs do — send us the part, the target temperature and the deadline, and we'll quote a mat built for it. Fast lead times, technical support you can reach on the phone, and a one-stop shop for the controller, cabling and accessories that make the heater work on your site.
