Plastic (PVC) hoses are widely used in many fields. What bothers us is that they are not durable. They will become no longer soft after a period of time. Forced bending may break. It is well known in the industry why plastic (PVC) hoses become rigid and brittle. The reason why PVC resins become soft when plasticizers are added. The reason for hardening is simple. It is caused by the precipitation and volatilization of plasticizers. The products made without plasticizers are rigid, such as water supply and drainage pipelines. In order to reduce costs and add inferior plasticizers, some manufacturers will harden and become brittle after 3-6 months of use. Others will use recycled granules. The products have irritating odor. Others will add chemical aromatics to cover up the irritating odor. In order to increase the weight of products, a large amount of calcium powder is added, totally ignoring the interests of consumers. Malicious competition. (Yitong plastic hose does not contain calcium powder)



The importance of plasticizer selection, many customers only pay attention to the price, not to the intrinsic product, which is irresponsible for themselves and customers, some friends said, this thing also can not see what ah? In fact, it is very simple, you can get the hose through the sense of smell to identify, poor plasticizers have a pungent odor, and environmental plasticizers are odorless. Second, we can bend back and forth several times after we get the hose. Look at the creases. The products with calcium powder are white, but those without calcium powder are not intact. Short-term experiments prove that two samples can be exposed to the sun at the same time. After 30 days or so, the hose will change obviously, and the hose will begin to aging and hardening. This shows that plasticizer weathering resistance is not strong, plasticizer precipitation volatilization, hose into a hard pipe, once broken off, greatly reducing the service life of hose.



Through the unremitting efforts of Yitong Plastic Research and Development Team, we devote ourselves to the research and development of PVC hose. The main factor for the hardening of hose is the precipitation of plasticizer. In 2012, the company developed WVR to protect plasticizer from volatilization. While absorbing plasticizer, it can form a strong outside of plasticizer. No matter how bad the environment is, the plasticizer will not evaporate. The cluster factor (WVR) developed by Yitong Plastics can reach 165 degrees of heat-resistant particles, and the radiation resistance to high-intensity ultraviolet radiation will remain unchanged. After five years of use, the physical properties of Yitong plastic hose reach more than 90%.
