Special polymers replace polycarbonate

Flame retardant, extrudable, and co-extrudable grades of Isoplast polymers come in various hardness levels. The polymers are a rigid plastic with chemical and impact resistance. They work well as replacements for polycarbonate, in applications that encounter stress cracking, and those that are difficult to color or tint. Other features include low-temperature flexibility, toughness, and abrasion and wear resistance in combination with chemical or hydrolysis resistance.

Non-Halogen Flame Retardant Material Adds More

Estane X-1425 thermoplastic polyurethane (TPU) delivers lower smoke generation. The material is intended for wire and cable jacketing in nonhalogen flame retardant applications. The industry is placing greater emphasis on the development of new compounds that produce lower smoke and higher Limited Oxygen Index (LOI) to reduce flame spread. Estane X-1425 TPU meets this industry demand for wire and cable jacketing used in applications such as robotics and industrial equipment where lowsmoke fire resistant materials are necessary. The material provides an LOI of 33 and achieves a UL vertical burn rating of V0. Estane TPUs are known for their superior abrasion, wear, tear and puncture resistance  compared with conventional materials such as rubber or PVC.
