AuroraGuard™ compounds include rigid PVC, TPOs and TPEs that provide high-heat, Low-Smoke Zero-Halogen and flame-retardant properties. As a result, they are ideal for demanding applications that include appliance, automotive, battery, electrical, umbilicals, and wire and cable.
Low-Smoke Zero-Halogen (LSZH or LSOH) is a type of plastic used in the wire and cable industry for cable jacketing. LSOH cable jacketing is custom compounded to produce minimal smoke and low toxicity when exposed to fire.
Most network cables (CAT5, CAT6, etc.) are insulated with polyvinyl chloride (PVC), polyethylene, or thermoplastic urethane (TPU). In a fire, halogen-containing plastic releases hydrogen chloride, a poisonous gas that forms hydrochloric acid when it comes in contact with H2O. Low-Smoke Zero-Halogen cables do not produce this toxic combination of gas, acid, and smoke when exposed to flame.
Since no harmful toxins are actually released, LSOH material is usually used in poorly ventilated areas such as plenum, aircraft, rail cars, and tunnels in which smoke is likely to both build up and come into contact with people. Low-Smoke Zero-Halogen material is becoming very popular, and can be required when the safety of people and equipment is critical. Low-Smoke Zero-Halogen compound also has the added benefit of complying with the European Union’s Restriction of Hazardous Substances (RoHS) directive and similar North American safety and environmental standards.
Our innovative line of LSOH compounds fall into two families:
- Extrusion grades – By using special grades of metal hydroxide and very unique resin combinations, we were able to develop the series of one of the most flexible zero halogen compounds on the market, having a -50C to 90C+ continued use temperature rating, as well as exceptional physical and processing characteristics.
- Molding Grades – Using advanced phosphorus-nitrogen chemistry, we developed a high grade FR intumescent compound with UL 94 VO rating down to 40-45 mils. Other special characteristics of these compounds are good thermostability and low moisture sensitivity.
Aurora Plastics offers a portfolio of concentrates that includes more than 20 formulations.
The goal of concentrates is the ideal dispersion of additives in the polymer matrix. The fine, powdery feed material often tends to agglomerate and therefore is difficult to work with. Concentrates (masterbatches) with an additive share of 20 – 90% are available, depending on the feed material.
Using masterbatch increases the process stability. Additionally, since there is no handling of large powder masses, the environment and the work station remain clean.
Our portfolio of concentrates are divided into five main categories. When more than one additive is required, Aurora Plastics can combine two or several of these additives to provide multifunctional performance into a single custom concentrate, or the customer can combine them individually themselves when applicable.
- Flame Retardant (FR)
- Ultraviolet (UV)
- Odor Masking
