The key differences between food - grade PVC hose and regular PVC hose lie in safety and application.
First, consider the material composition. Food - grade PVC hose is manufactured using raw materials that meet food contact standards. It contains no harmful plasticizers or heavy metals. Even when it is in contact with water, beverages, or food ingredients, no harmful substances are released. Regular PVC hose, on the other hand, may use low - cost, non - food - grade additives and is unsuitable for contact with edible materials.
Next, consider the application scenarios. Food - grade PVC hose is primarily used in food processing, catering, and beverage delivery, such as wine delivery in distilleries or syrup delivery in milk tea shops. Regular PVC hose is suitable for non - food contact applications such as industrial drainage, agricultural irrigation, and equipment cooling, and should not be used to transport food or beverages.
There are also performance requirements. Food - grade PVC hose must pass specialized food contact safety testing. It has a smoother surface, is less susceptible to bacterial growth, and is easy to clean. Regular PVC hose focuses more on industrial properties such as wear and aging resistance, and has lower hygiene standards. The two should not be used interchangeably, as this may compromise food safety.
