Silicone Trim® EN45545-2 compliant type

Silicone trim, which is easy to install and maintain,
now has a new specification conforming to
EN45545-2 R22/R23 (European Railway Vehicle Standard) .

We have added a new series of One-Touch Easy & Convenience gasket silicone trims conforming to “HL (Hazard Level) -3”,
the most stringent of “EN45545-2 (European fire safety standard: combustion behavior requirements for materials used in railroad vehicles) R22/R23”.
The new series has excellent flame resistance and low smoke emission, and since it has been confirmed as compliant by a testing organization accredited under ISO/IEC17025, it can be easily adopted as gaskets and sealing materials.
The inner core is made of perforated metal made of stainless steel (SUS443), which excels in rust resistance, flexibility, and safety, and can be used in a variety of environments, such as outdoors and in places where it is difficult to handle. It can also be manufactured as a stand-alone product, not as a silicone trim.

Easy installation without adhesive

Features

Rust resistance

Made of rust-resistant stainless steel (SUS443).
Length cutting is also easier to install.

Low smoke generation

Compared to general silicone
rubber, the amount of smoke
emitted is extremely low,
making it easier to maintain a
clear field of vision in the event of a fire.

Easy Installation

Since it is simply clamped
onto a steel or plastic plate,
it can be easily installed. It is
also easy to install at corners
because it bends freely.

Good maintenance

No adhesives are used, so no
contamination occurs.
It is also removable for easy
maintenance.

Applications

Gaskets and sealing materials for railway vehicles, packing and cable covers for testing equipment, electrical equipment, and inspection equipment, etc.
