Olefin carpets (polypropylene) Characteristics
Olefin Carpets is an attractive, inexpensive fiber that’s strong and resists fading, but it’s not as resilient as nylon. It’s most often made into a looped Berber with a nubby weave that conceals dirt. It has good stain, static and mildew resistance. Olefin carpeting is often selected for high-traffic “clean” areas such as family rooms and play areas. It costs $8 to $25 per sq. yd.
Olefin Carpets Advantages
- Olefin carpets are very moisture resistant. It will absorb only one tenth of 1% of its weight in water. This leads to some pros and some cons.
- Very difficult to stain.
- Great for outdoor applications (stadium or pool)
- Chemical Resistant – Most chemicals and bleaches won’t damage it at all
- Solution dyeing makes it resistant to fading.
- Lightweight – It is the only common carpet fiber that will float on water. ( Except celluloid)
- Strong – It wears well except for resiliency factor (see cons).
- It has good cleanability and stain release. (Except oil/petroleum-based stains – see cons)
Olefin Carpets disadvantages
- Olefin carpets is not a resilient fiber. When crushed it does not regain its original shape easily. Traffic areas tend to lie down, showing “apparent soiling”. Furniture marks can be permanent reminders to the owner of where his furniture used to be.
- It is a very heat sensitive fiber. Its melting point is around 300 degrees but damage can occur at lower temperatures.
- Olefin can be damaged by Friction – Even dragging a heavy piece of furniture across an olefin carpet can cause permanent marks from the heat generated by friction.
- Like polyester, extended exposure to oil-based soils may become permanent.
- Olefin is very difficult to dye due to its low absorbency rate. It is almost always solution dyed.
- Quite often, Olefin is in a glue-down situation, which creates a potential to brown from soil wicking from the base of the yarns due to incomplete soil removal. Over wetting and/or slow drying increases the likelihood.
