What concerns the abrasion resistance of spiral guard
In daily life and production, hoses and pipes are common sights. Among them, PVC hoses and PE hoses are widely used. Both materials offer great value, but which one is superior? Let’s explore this question.
Hygienic Performance Comparison of PVC and PE Pipes
Contrary to common belief, PVC can be just as hygienic and non-toxic as PE. A major misconception about plastic products is the “toxic or non-toxic” debate, and PVC often bears the brunt of this misunderstanding. In scientific terms, the question isn’t about toxicity; rather, it’s about whether a plastic is of general use or food hygiene grade. In fact, most plastics are non-toxic. As a result, they can serve as food packaging, medical supplies, and can even be used to create human body parts like bones and organs.
PVC products come in both general and food grades. Food hygiene grade PVC products have strict limits on the heavy metal content in additives and vinyl chloride monomer (VCM) in PVC. However, this doesn’t mean general grade PVC products are toxic. Instead, it simply means they aren’t suitable for food hygiene applications. It’s inaccurate to claim that people can’t use or touch them. On the other hand, processed PE typically has fewer additives, making it hygienically safe and non-toxic. The controversy surrounding PVC mainly arises from these two aspects.
In addition, both PVC and PE are eco-friendly materials. You can recycle and reuse them, contributing to environmental sustainability.
