Chemical Related product Safeguard Ecology Chemical Pipe (U-PVC) Pipe with excellent chemical-resistance, high pressure-resistance and long-term durability P.107 Double Contained Pipe & Fittings (U-PVC, HI-PVC) PP Pipe & Fittings (PP) Detects leakage point and prevents fluid from scattering to outside P.123 DIN Environment-friendly clean material (generates no dioxin when burnt) with excellent corrosion- and heat-resistance P.141 Lineup Related Products P.175 Material Characteristics U-PVC The most standard PVC with excellent chemical and physical characteristics. HI-PVC A material still maintaining the excellent characteristics of PVC with improved impact-resistance. A material originally made as a countermeasure against the water hammer pressure for tap water piping materials. C-PVC A material still maintaining the excellent characteristics of PVC with improved heat-resistance to 90°C. PP Has a small specific gravity and excellent water-resistance, electric insulation capability and dynamic/mechanical characteristics in high temperatures. Cannot be bonded as PVC but has an excellent chemical-resistant balance. PVDF Highly strong and impact-resistant. Although usage is limited to alkali and some solvents, the chemical-resistance against other chemicals exceeds PVC and PP. Used in the temperature between -40 and 120°C and has an excellent wear-resistance and electrostatic property. Gas-barrier is superior than PTFE. 005
