DATOS DE RESISTENCIA QUÍMICA DEL CLORURO DE POLIVINILO (PVC)

Fuente: PPI TR-19 Plastic Pipe Institute, Nueva York, Nueva York

Esta tabla está destinada a ayudar al diseñador en las decisiones sobre el transporte / transporte de productos químicos no diluidos. La información de resistencia química para tuberías de PVC proporcionada se basa en la inmersión a corto plazo de tiras de PVC sin estresar en productos químicos y, en menor medida, en la experiencia de campo.

R – En general resistente. C – Menos resistente que R pero aún adecuado para algunas condiciones. N – No resistente.
