Technical Brief
Long Glass Fiber (LGF) Compounds exhibit excellent price-to-performance characteristics and are routinely considered as a cost management alternative to higher density and higher cost reinforced compounds. LGF Compounds offer the following benefits:
- Light weight
- Easy to mold
- Superior chemical resistance
- Properties not effected by humidity
- High impact strength
- Reduced cost
- Low process and mold temperatures
- Minimal pre-drying required
At 50% relative humidity, LGF PP Compounds have comparable physical properties to Short Glass Fiber reinforced Nylon (SGF PA) 6 and 6/6 Compounds; however, LGF PP Compounds provide a competitive advantage due to lower price and lower specific gravity.
In many applications, LGF PP compounds can be used as drop-in replacements for PA compounds because they can meet physical performance requirements, offer processing advantages and can be used in existing molds with little or no alterations. In addition, polypropylene maintains its mechanical properties in high humidity.
LGF PP compounds have a lower specific gravity than reinforced nylons, resulting in more parts per lb/kg of material purchased. This cost and weight reduction is appealing to processors and OEMs trying to reduce costs.
