PP-R Pipe Grade - b2bPolymers.com

1 PP-R Pipe Grade Hot and cold water supplying pipe Under floor heating pipe Radiator heating pipe Pipes for chemical and agricultural usesThe Advantages of R200P- Long-term service life of over 50 years- Excellent chemical stability- Environmental friendliness- Outstanding installation safety- Easy manufacturing processibilityR200P, produced and marketed by hyosung Corporation is PolypropyleneRandom Copolymer (PP-R), a result of up-to-date PP manufacturing process andHYOSUNG's polymerization technology through over 35 years experience. R200P is the most suitable material known for all types of pipe application, inparticular hot and cold water supplying system, heating system and drinking water R200 PHot waterBoilerColdwaterKitckenBath tubRadiatorFloor heatingWash standResistance to internal hydrostatic pressureConditionRequiredTypical Value of R200 PTest Method20 C95 C110 C16 MPa1hr1,000 hrs8,760 hrs>10 hrs>5,000 hrs>10,000 hrsISO 1167 ISO 1167 ISO 1167* The data of table are relative and represent empirical values obtained in various Test Method Unit DataDensityASTM D792g/ C, C.

Because of this characteristics it is not easy to mix thenatural resin with color master batch during pipe production.

3 Therefore we would like to recommand to use color gradefor better quality actual extrusion conditions will depend on the type of customer's , the most suitable processing conditons have to be sought case by the following conditions should be used as a guide. And, hyosung canprovide rheological data on the customer's request.

4 It is important to set the moldingcondition to the lowest possible stress and to appropriately adjust the temperature.
