Our silicone rubber heating wire is manufactured with high quality and stable property in mind. It will surely meet and exceed customers' expectations in terms of electrical insulating ability, flexibility, and excellent heat conductivity. Therefore, please feel secure in purchasing this product.

Currently, the heating wire has found countless applications in many fields. For instance, it is widely used in electric cushion, electric cloth, animal pet, jade mattress, electric shoes, electric massage armchair, car windows, electric towel rack, and heat preservation type rice cooker. In addition, the wire is usually used in air conditioner, refrigerator and cooler to avoid surface condensation formation. It can also be used as anti-freeze heating wires for pipe and tank, etc.

Our products mainly come in four models, including SH-SR-20, SH-BSR-20, SH-2SR-20, and SH-SR2-20. The technical parameters of these models are nearly the same.
