Electrically insulated cords

Flat lavsan cords are designed for bandaging electric motors, insulating electrical appliances and special-purpose products.

Lavsan cord is made of polyester thread by weaving. It is soft and flat, and does not have a core.

The materials are highly resistant to thermal shock and increased radiation, have excellent electrical insulating properties at elevated temperatures and high humidity, can be used for a long time at t 200 C and for a short time at higher temperatures up to 250 C.

Products made of polyester threads are resistant to organic and inorganic acids even at elevated temperatures (except hydrofluoric, phosphoric, hydrochloric) and weak alkalis, they are an excellent substitute for asbestos, are not hazardous to human health (non-toxic, non-combustible, non-flammable).

Polyester cords are elastic, flexible, resilient, resistant to vibrations, humidity, solar radiation. have good adhesion to high-temperature adhesives.
