Waterway Use Impact-Resistant Rigid Polyvinyl Chloride Pipe HI-VP 25 × 1m (1 set: 4 pieces) (JIS K 6742 standard product) Nominal diameter (approximate inner diameter): 25 mm Outer diameter: 32.0 mm ± 0.2 mm Thickness: 3.5 mm ± 0.3 mm Weight: 0.44 kg (reference) Color: Dark blue Features: This is a PVC pipe with excellent impact resistance. ■ HIVP pipe is strong against impact Standard VP pipes have low strength against impact, which can lead to breakage during installation or use. Additionally, at low temperatures, their impact resistance decreases further, making them more prone to cracking, which has been a problem particularly in cold regions. Therefore, the material has been improved, significantly enhancing the performance against impact, resulting in the HIVP pipe. ■ Reasons for the strength of HIVP pipe Standard PVC resin is mixed with impact resistance modifiers (such as ABS, MBS, EVA, acrylic rubber, and chlorinated polyethylene, which have rubber-like properties) as reinforcing agents. By mixing this reinforcing agent at about 5-20%, the particles of the reinforcing agent absorb impact energy and become more resilient, preventing breakage.
