RTP Company Introduces PEEK Long Fibre Compounds

Specialty compounder RTP Company has expanded its Long Fibre product line with Victrex PEEK (Polyetheretherketone).

These RTP 2200 Series PEEK Long Fibre Compounds significantly improve impact strength when compared to conventional short fibre PEEK materials, making them ideal for metal replacement applications.

“”RTP Company’s Long Fibre Compounds are superior to short fibre products because the longer fibres mechanically interlock, which typically reduce warpage and shrinkage and absorb higher stress levels,”” commented Bob Wick, Product Manager at RTP Company. “”PEEK Long Fibre Compounds from RTP Company offer several important additional advantages, with the most noteworthy benefit being a significant increase in notched Izod impact.””

Recent tests by RTP prove that the company’s Long Fibre PEEK 30% glass-filled compounds have more than twice the impact strength of short fibre PEEK 30% glass-filled compounds. Long fibre PEEK containing 40% and 50% long glass fibre also demonstrated dramatic increases over their short glass fibre counterparts (see graph). Other expected benefits include improved long-term creep and fatigue and better dimensional stability especially at elevated temperatures.

Long fibre compounds are ideal metal replacement materials. They offer many benefits including weight reduction, increased throughput, part consolidation, reduction of secondary processing, and improved chemical resistance to name a few. PEEK Long Fibre Compounds are suitable for metal replacement applications in the compressor and pump markets where excellent chemical resistance, high mechanical properties, elevated temperatures, and outstanding wear resistance are required.
Datasheets and additional technical information can be obtained from the RTP website.
