Resistoflex® Polypropylene-Lined

Polypropylene is our most economical system. It has good resistance to both inorganic acids and bases.

Polypropylene Homopolymer

• Used in 1”-8” Swaged Pipe
• Used in 1”-12” fittings
• Temperature capability 0º F– 225º
• Will exhibit brittle behavior as temperatures approach 0 F (-18 C)
• Possesses some abrasion resistance
  
  

Polypropylene Copolymer

• Used in 1’-12” Thermalok Pipe
• More ductile than homopolymer PP and hence has improved low temperature resistance
• Temperature capability -20 º F – 225º
• Better abrasion resistance
  
  

Typical industries using PP

• Water Treatment
• Chemical Processing
• Food and Beverage
• Steel & stainless steel pickling
• Power Generation

Common PP Applications

• Up to 38% HCl
• <90%  H2SO4
• <30%  HNO3
• <60% HF
• Sea Water / Brine
• NaOH (caustic)
• Ultrapure Water
• Fruit Juices
