Polyvinyl chloride gets a lot of bad press, but it remains the third most produced resin in the United States. According to data from the American Chemistry Council, the domestic market for PVC last year was 14.4 billion pounds, up 3.1% from 2010 despite a still sluggish housing and construction market.
A new compound from Teknor Apex (Pawtucket, RI) is a reminder that PVC is an economical and highly functional alternative to engineering thermoplastics for many durable applications. The new high-flow Apex RM 8911 compound exhibits 25 to 50% greater flow in relative spiral flow (RSF) tests as compared with standard RPVC grades, while providing a high gloss finish.
It targets large products such as appliance panels, thin-wall parts, and complex structures with elaborate flow paths. The compound is UL-94 recognized for applications requiring V-0 or 5 VA flammability ratings. Benefits of PVC include strength, durability, chemical resistance, and low viscosity for ease of processing.
Michael J. Renzi, business development manager for the Vinyl Division of Teknor Apex, noted in a press release: “Our new Apex RM 8911 compound is the latest in a growing range of RPVC products from Teknor Apex. Drawing on decades of experience with vinyl technology and on our expanded manufacturing capabilities, Teknor Apex is poised to become a major player in RPVC worldwide.”
RPVC stands for rigid polyvinyl chloride.
