Insulating silicone foam provides a protective layer for flexible heaters!

Flexible heater substrates have long been widely used in semiconductor, medical, clean energy, industrial, and food and beverage industries due to their reliable performance and long service life. They possess excellent thermal stability, electrical insulation, a UL-certified Relative Temperature Index (RTI) of 220°C, and are flexible and easy to design.

As countries worldwide reach a consensus on the importance of energy conservation, emission reduction, and curbing climate change, more and more end-users of flexible heaters are demanding improved energy efficiency and reduced heat loss. When heaters are operating, their surfaces continuously radiate heat, which is itself a waste of energy and poses a risk of accidental burns to workers and increases air conditioning costs due to the need to lower workshop temperatures. To better address this issue and improve heater efficiency and safety,

let's first look at the structure of how Yalong insulating silicone foam is combined with flexible heaters.

This structure, which layers Yalong insulating silicone foam over the heater, achieves the following benefits:

Lower surface temperature

Reduced heat loss

Enhanced protection for the flexible heater and operators

A triple benefit!

The features of Yalon insulating silicone foam include:

Complies with ASTM D1056 2D3 (Medium Level) standard

UL 94 HB, 150℃ RTI (ARLON C9)

Uniform closed-cell structure

Wide operating temperature range (-56℃ to 220℃)

Excellent thermal insulation performance

Low TML (Total Liquidity) <1%

Low water absorption <5%

RoHS compliant

Smooth and uniform surface texture

10-year shelf life

This product series offers customers numerous benefits, including:

Long-lasting thermal insulation and thermal stability, ensuring long service life and reliable operation, reducing downtime, and improving production efficiency

Reduced heater heat loss and air conditioning energy consumption due to ambient temperature rise, resulting in energy saving and environmental protection

Meets the flame retardant requirements for semiconductor applications (UL 94) HB)

No adhesive required, simple manufacturing process, easily bonded to flexible heater substrates, especially ARLON flexible heater substrates

Low gas release, reducing pollution to the environment and sensitive equipment

Supply in rolls, easy to use and process

We also compared this series of products with similar products on the market. ARLON thermal insulation silicone foam has lower gas release, extremely low water absorption, better thermal stability, and more uniform cell structure. It has unparalleled adhesion to silicone flexible heater substrates without adhesives, performing better in various high-temperature and harsh applications.

Currently, ARLON thermal insulation silicone foam is available in two models:

ARLON C9 material (UL certified) is made from ARLON 27 flexible insulating compound, exhibiting excellent thermal stability even in harsh flexible heater applications. ARLON D5 material is made from ARLON 10 flexible insulating compound, which, thanks to the inherent properties of silicone, offers significant product advantages.
