Borealis Beta-PPR allows the use of thinner and smaller pipes for hot and cold water(09/04/2007)
PP-R materials were brought to the market more than 20 years ago and have been used predominantly for hot and cold water pipe systems. Due to its reliability, ease of installation, corrosion-resistance and other benefits, PP-R has made a major contribution to the growth of plastic pipes for heating and plumbing applications. However, over that time there has been no substantial advance in the performance of PP-R resins. The strength of the raw material, which is the basis for calculating the wall thicknesses of the pipe and determines the material consumption per unit length and the hydraulic capacity of the installed pipe system, has not changed until now. Borealis has developed Beta-PPR™ RA7050, which delivers a clear improvement in the long term strength compared to current Polyp... [read full article]
PP-RCT recognised as a category under new DIN standards for water pressure pipes(02/04/2007)
According to EN ISO 1043 designations, PP-RCT is a PP random copolymer with special crystalline structure. This structure gives improved pressure resistance particularly at elevated temperatures, offering more than a 50% improvement in long-term strength at 70°C over 50 years compared to standard PP-R materials. As a result, pipes based on this material can be produced with thinner walls thus with a larger internal pipe diameter, delivering a range of benefits to the plumbing industry and homeowners. The German standards for polypropylene (PP) pressure pipes have been revised in 2006. The designations PP-H100, PP-B80 and PP-R80 have been withdrawn as they did not reflect the required behaviour at elevated temperatures and were changed to PP-H, PP-B and PP-R. Also, PP-RCT has now been of... [read full article]
